  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The configurations shown in the following embodiments are merely examples, and the present invention is not limited to the illustrated configurations.

  In addition, the commands in the following embodiments are determined based on, for example, the Open Network Video Interface Forum (hereinafter sometimes referred to as ONVIF) standard. In the ONVIF standard, for example, this command is defined by using the XML Schema Definition language (hereinafter sometimes referred to as XSD).

Example 1
The network configuration according to this embodiment will be described below with reference to FIG. More specifically, FIG. 1 is a diagram illustrating an example of a system configuration of the monitoring system according to the present embodiment.

  In the monitoring system in the present embodiment, the imaging device 1000 and the client device 2000 are connected to each other via the IP network 1500 (in a state where they can communicate with each other). Accordingly, the imaging apparatus 1000 can distribute the captured image to the client apparatus 2000 via the IP network 1500.

  Note that the imaging apparatus 1000 in this embodiment is a monitoring camera that captures a moving image, and more specifically, a network camera used for monitoring. The client device 2000 in this embodiment is an example of an external device such as a PC. Further, the monitoring system in the present embodiment corresponds to an imaging system.

  The IP network 1500 is assumed to be composed of a plurality of routers, switches, cables, and the like that satisfy a communication standard such as Ethernet (registered trademark). However, in this embodiment, any communication standard, scale, and configuration may be used as long as communication between the imaging device 1000 and the client device 2000 can be performed.

  For example, the IP network 1500 may be configured by the Internet, a wired LAN (Local Area Network), a wireless LAN (Wireless LAN), a WAN (Wide Area Network), or the like. Note that the imaging apparatus 1000 according to the present embodiment may be compatible with, for example, PoE (Power Over Ethernet (registered trademark)), and may be supplied with power via a LAN cable.

  The client apparatus 2000 transmits various commands to the imaging apparatus 1000. These commands are, for example, a command for changing the imaging direction and angle of view of the imaging apparatus 1000, a command for changing imaging parameters, a command for starting streaming of the captured image, and the like.

  On the other hand, the imaging apparatus 1000 transmits a response to these commands and a stream of captured images to the client apparatus 2000. Further, the imaging apparatus 1000 changes the angle of view in accordance with a command for changing the angle of view received from the client apparatus 2000.

  Next, FIG. 2 is a diagram illustrating an example of a hardware configuration of the imaging apparatus 1000 according to the present embodiment. The imaging optical system 2 in FIG. 2 forms an image of a subject imaged by the imaging device 1000 on the imaging element 6 via the optical filter 4. Here, in this embodiment, the optical filter 4 is, for example, an infrared cut filter (Infrared Cut Filter; hereinafter referred to as IRCF) that cuts off infrared rays.

  The optical filter 4 is inserted into the optical path between the image pickup optical system 2 and the image pickup element 6 by a drive mechanism (not shown) based on a drive signal from the optical filter drive circuit 24 (for example, a plunger using an electromagnet). Get rid of. The image sensor 6 is composed of a CCD, a CMOS, or the like. The imaging element 6 captures an image of the subject formed by the imaging optical system 2.

  Furthermore, the image sensor 6 outputs a captured image by photoelectrically converting the captured subject image. Here, blocking infrared rays means that infrared rays are greatly attenuated, and does not have to block 100%.

  Note that the image pickup device 6 in this embodiment corresponds to an image pickup unit that picks up an image of a subject formed by the image pickup optical system 2.

  The video signal processing circuit 8 outputs only the luminance signal of the captured image output from the image sensor 6 or is output from the image sensor 6 in accordance with an instruction from a central processing circuit (hereinafter also referred to as CPU) 26 described later. The luminance signal and color difference signal of the captured image are output to the encoding circuit 10. In addition, the video signal processing circuit 8 outputs the luminance signal of the captured image output from the image sensor 6 to the luminance measurement circuit 18 in accordance with an instruction from the CPU 26.

  When only the luminance signal is output from the video signal processing circuit 8, the encoding circuit 10 compresses and encodes the output luminance signal, and outputs the compressed and encoded luminance signal to the buffer 12 as a captured image. On the other hand, when the luminance signal and the color difference signal are output from the video signal processing circuit 8, the encoding circuit 10 compresses and encodes the output luminance signal and the color difference signal, and the compressed luminance signal and the color difference signal are encoded. Is output to the buffer 12 as a captured image.

  The buffer 12 buffers the captured image output from the encoding circuit 10. Then, the buffer 12 outputs the buffered captured image to a communication circuit (hereinafter sometimes referred to as I / F) 14. The I / F 14 packetizes the captured image output from the buffer 12 and transmits the packetized captured image to the client apparatus 2000 via the communication terminal 16. Here, the communication terminal 16 includes a LAN terminal to which a LAN cable is connected.

  The I / F 14 corresponds to a receiving unit that receives a command related to insertion / removal of the optical filter 4 from the external client device 2000.

  The luminance measurement circuit 18 measures the luminance value of the current subject of the imaging apparatus 1000 based on the luminance signal output from the video signal processing circuit 8. Then, the luminance measurement circuit 18 outputs the measured luminance value to the determination circuit 20. The determination circuit 20 compares the luminance value of the subject output from the luminance measurement circuit 18 with the threshold value of the luminance of the subject set by the CPU 26, and outputs the comparison result to the CPU 26.

  The timer circuit 22 is set with a delay time from the CPU 26. In addition, the timer circuit 22 counts the time elapsed after receiving this instruction in accordance with the instruction to start timing from the CPU 26. Then, when the set delay time has elapsed, the time measuring circuit 22 outputs a signal indicating that the delay time has elapsed to the CPU 26.

  The optical filter drive circuit 24 receives an instruction from the CPU 26 and removes the optical filter 4 from the optical path of the imaging optical system 2. Further, the optical filter driving circuit 24 receives an instruction from the CPU 26 and inserts the optical filter 4 into the optical path of the imaging optical system 2. The optical filter drive circuit 24 in this embodiment corresponds to an insertion / removal unit that inserts / removes the optical filter 4 with respect to the optical path of the imaging optical system 2.

  The CPU 26 comprehensively controls each component of the imaging device 1000. Further, the CPU 26 executes a program stored in a nonvolatile EEPROM (Electrically Erasable Programmable Read Only Memory; hereinafter referred to as EEPROM) 28 that can erase data. Alternatively, the CPU 26 may perform control using hardware.

  The EEPROM 28 can store parameters for operating the imaging apparatus 1000, commands received from the client apparatus 2000, and the like. The CPU 26 in this embodiment corresponds to a control unit that controls the optical filter driving circuit 24 that inserts and removes the optical filter 4.

  In this embodiment, IRCF is used as the optical filter 4, but the present invention is not limited to this. For example, as the optical filter 4, a beam splitter that changes the destination of transmitted light, such as an ND filter that reduces the amount of incident light, a filter that transmits only light of a specific wavelength, a polarization filter that transmits only a specific polarization component, Different optical filters may be used.

  Next, FIG. 3 is a flowchart for explaining processing executed by the CPU 26 when an instruction command for instructing insertion or removal of the optical filter 4 with respect to the optical path of the imaging optical system 2 is received by the I / F 14. It is.

  In step S301, the CPU 26 determines whether an instruction command that has been subjected to appropriate packet processing by the I / F 14 has been received. If the instruction command is received, the CPU 26 proceeds to step S302. If not received, the CPU 26 returns the process to step S301.

  In step S302, the CPU 26 analyzes what kind of command the input instruction command (command received by the I / F 14) is.

  In step S303, the CPU 26 determines whether the command is an insertion command based on the result analyzed in step S302. If the CPU 26 determines that the command is an insertion command, the process proceeds to step S304. On the other hand, if the CPU 26 determines that the command is not an insertion command, the process proceeds to step S305.

  In step S <b> 304, the CPU 26 controls the optical filter driving circuit 24 to insert the optical filter 4 in the optical path of the imaging optical system 2.

  Here, in the present embodiment, imaging of the subject by the imaging apparatus 1000 with the optical filter 4 inserted in the optical path of the imaging optical system 2 is referred to as visible light imaging (normal imaging). That is, in visible light imaging, the imaging apparatus 1000 captures an image of the subject in a state where light from the subject is incident on the image sensor 6 via the optical filter 4.

  When visible light imaging is performed by the imaging apparatus 1000, the CPU 26 places importance on the color reproducibility of the captured image output from the imaging device 6 and instructs the video signal processing circuit 8 to output the luminance signal and the color difference signal. Is output to the encoding circuit 10. As a result, the I / F 14 delivers a color captured image. Therefore, in this embodiment, when visible light imaging is performed by the imaging apparatus 1000, the imaging mode of the imaging apparatus 1000 may be referred to as a color mode.

  In step S305, if the CPU 26 determines that the command is not an insertion command in step S303, the CPU 26 determines whether the command is a removal command based on the result analyzed in step S302. If the CPU 26 determines that the command is a removal command, the process proceeds to step S306. On the other hand, if the CPU 26 determines that the command is not an extraction command, the process proceeds to step S307.

  In step S <b> 306, the CPU 26 controls the optical filter driving circuit 24 to remove the optical filter 4 from the optical path of the imaging optical system 2.

  Here, in the present embodiment, imaging the subject with the imaging apparatus 1000 with the optical filter 4 removed from the optical path of the imaging optical system 2 is referred to as infrared imaging. That is, in infrared imaging, the imaging apparatus 1000 captures an image of the subject in a state where light from the subject is incident on the imaging element 6 without passing through the optical filter 4.

  When infrared imaging is performed by the imaging apparatus 1000, the CPU 26 instructs the video signal processing circuit 8 because the color balance of the captured image output from the imaging device 6 is lost, and encodes only the luminance signal. 10 to output. As a result, the I / F 14 delivers a monochrome captured image. Therefore, in the present embodiment, when infrared imaging is performed by the imaging apparatus 1000, the imaging mode of the imaging apparatus 1000 may be referred to as a monochrome mode.

  In step S307, if the CPU 26 determines that the command is not a removal command in step S305, the CPU 26 determines whether or not the automatic insertion / removal command includes an adjustment value indicating a luminance threshold based on the result analyzed in step S302. Here, an adjustment value relating to insertion / removal of the optical filter 4 can be described in the automatic insertion / removal command.

  This adjustment value can be omitted. The adjustment value is, for example, an adjustment value indicating a luminance threshold value or an adjustment value indicating a delay time.

  If the CPU 26 determines that it is included, the CPU 26 advances the process to step S308, and sets an adjustment value indicating a luminance threshold corresponding to the adjustment value included in the command in the determination circuit 20.

  On the other hand, if the CPU 26 determines that it is not included, the CPU 26 advances the processing to step S 309, reads out the luminance threshold value from the adjustment values stored in advance in the EEPROM 28, and sets it in the determination circuit 20.

  In step S310, the CPU 26 determines whether or not the command includes an adjustment value indicating the delay time based on the result analyzed in step S302. If it is determined that the CPU 26 includes the CPU 26, the process proceeds to step S 311, and the delay time corresponding to the adjustment value included in the command is set in the timer circuit 22.

  On the other hand, if the CPU 26 determines that it is not included, the CPU 26 advances the processing to step S 312, reads the delay time from the adjustment values stored in advance in the EEPROM 28, and sets the delay time in the timer circuit 22.

  In step S313, the CPU 26 determines whether or not the optical filter 4 is located outside the optical path. If the CPU 26 determines that the object is out of the optical path, the process proceeds to step S314. On the other hand, if the CPU 26 determines that it is in the optical path, the process proceeds to step S315.

  In step S314, when the CPU 26 determines that the optical filter 4 is out of the optical path in step S313, the determination circuit 20 determines whether or not the luminance of the current subject exceeds the luminance threshold set by the CPU 26. . If the CPU 26 determines that the number is higher, the process proceeds to step S316. On the other hand, when it determines with not exceeding, a process is returned to step S313.

  In step S316, the CPU 26 instructs the timing circuit 22 to start timing, and proceeds to step S318.

  In step S318, the CPU 26 determines whether or not the current luminance of the subject exceeds the luminance threshold set by the CPU 26 by the determination circuit 20 before the signal indicating that the delay time has elapsed is input from the timer circuit 22. Determine. If the CPU 26 determines that the number is higher, the process proceeds to step S320. On the other hand, when it determines with not exceeding, a process is returned to step S313.

  In step S320, the CPU 26 determines whether or not a signal indicating that the delay time has elapsed is input from the timer circuit 22. When the signal is input, the CPU 26 advances the process to step S322. On the other hand, if no signal is input, the process returns to step S318.

  In step S322, the optical filter drive circuit 24 is instructed to insert the optical filter 4 into the optical path of the imaging optical system 2.

  On the other hand, in step S315, if the CPU 26 determines in step S313 that the optical filter 4 is in the optical path, the determination circuit 20 determines whether the current luminance of the subject is below the luminance threshold set by the CPU 26. Determine.

  If the CPU 26 determines that the number is below, the process proceeds to step S317. On the other hand, if it is determined that it is not lower, the process returns to step S313.

  In step S317, the CPU 26 instructs the timing circuit 22 to start timing, and proceeds to step S319.

  In step S319, the CPU 26 determines whether or not the current luminance of the subject is below the luminance threshold set by the CPU 26 by the determination circuit 20 before the signal indicating that the delay time has elapsed is input from the timer circuit 22. Determine. When it is determined that the CPU 26 is below the CPU 26, the process proceeds to step S321. On the other hand, if it is determined that it is not lower, the process returns to step S313.

  In step S <b> 321, the CPU 26 determines whether or not a signal indicating that the delay time has elapsed is input from the timer circuit 22. When the signal is input, the CPU 26 advances the process to step S323. On the other hand, if no signal is input, the process returns to step S319.

  In step S323, the optical filter drive circuit 24 is instructed to remove the optical filter 4 from the optical path of the imaging optical system 2.

  Next, FIG. 4 is a diagram illustrating an example of a hardware configuration of the client apparatus 2000 according to the present embodiment. The client device 2000 in the present embodiment is configured as a computer device connected to the IP network 1500, and is typically a general-purpose computer such as a personal computer (hereinafter sometimes referred to as a PC). .

  The CPU 426 in FIG. 4 controls each component of the client device 2000 in an integrated manner. The CPU 426 executes a program stored in an EEPROM 428 described later. Alternatively, the CPU 426 may perform control using hardware. The EEPROM 428 is used as a program storage area executed by the CPU 426, a work area during program execution, and a data storage area.

  A digital interface unit (hereinafter also referred to as I / F) 414 receives an instruction from the CPU 426 and transmits a command or the like to the imaging apparatus 1000 via the communication terminal 416. Also, the I / F 414 receives a command response, a captured image that has been streamed, and the like from the imaging apparatus 1000 via the communication terminal 416. The communication terminal 416 includes a LAN terminal to which a LAN cable is connected.

  The input unit 408 includes, for example, a button, a cross key, a touch panel, a mouse, and the like. The input unit 408 accepts input of instructions from the user. For example, the input unit 408 can accept input of various command transmission instructions to the imaging apparatus 1000 as instructions from the user.

  In addition, when a command transmission instruction to the imaging apparatus 1000 is input from the user, the input unit 408 notifies the CPU 426 that the input has been made. Then, the CPU 426 generates a command for the imaging apparatus 1000 according to the instruction input to the input unit 408. Next, the CPU 426 instructs the digital interface unit (hereinafter sometimes referred to as I / F) 414 to transmit the generated command to the imaging apparatus 1000.

  Furthermore, the input unit 408 can accept an input of a user response to an inquiry message to the user generated by the CPU 426 executing a program stored in the EEPROM 428.

  Here, the CPU 426 decodes and expands the captured image output from the I / F 414. Then, the CPU 426 outputs the decoded and expanded captured image to the display unit 422. Thereby, the display unit 422 displays an image corresponding to the captured image output from the CPU 426.

  The display unit 422 can display an inquiry message or the like to the user that is generated when the control unit 2001 executes a program stored in the storage unit 2002. As the display portion 422 in this embodiment, a liquid crystal display device, a plasma display display device, a cathode ray tube (hereinafter sometimes referred to as CRT) display device such as a cathode ray tube, or the like can be used.

  As described above, the internal configurations of the imaging apparatus 1000 and the client apparatus 2000 have been described. The processing blocks illustrated in FIGS. 2 and 4 are for describing preferred embodiments of the imaging apparatus and the external apparatus according to the present invention. This is not the case. Various modifications and changes can be made within the scope of the present invention, such as including an audio input unit and an audio output unit.

  Next, FIG. 5 is a diagram for explaining the operation when the adjustment values of the brightness threshold value and the delay time are set in the imaging apparatus 1000 according to the present embodiment. A graph 101 in FIG. 5 shows a temporal change in luminance of the subject of the imaging apparatus 1000. This graph 101 shows that the luminance of the subject decreases as time elapses, such as during a sunset.

  The luminance threshold 102 indicates a luminance threshold used for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2. The luminance threshold 103 indicates a luminance threshold used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2.

  In this embodiment, the luminance threshold value described in the automatic insertion / removal command is normalized to a predetermined range of values. Specifically, the luminance threshold is limited to a value from −1.0 to +1.0. Therefore, as shown in FIG. 5, the specifiable range of the luminance threshold 102 and the luminance threshold 103 is a range from −1.0 to +1.0.

  For example, as shown in FIG. 5, when the luminance value falls below the luminance threshold value 103 due to a decrease in the luminance value of the subject, the CPU 26 sets a delay time in the timing circuit 22 and starts timing in the timing circuit 22. Instruct. Thereby, the time measuring circuit 22 starts time measurement.

  In FIG. 5, the luminance value of the subject is lower than the luminance threshold 103 at point A. The time when it falls below is t1. The CPU 26 sets a delay time in the timing circuit 22 when the time is lower than this, and the optical filter 4 is inserted into the optical path of the imaging optical system 2 until the set delay time elapses. The filter 4 is not removed.

  Such an operation of the CPU 26 can prevent the visible light imaging and the infrared imaging of the imaging apparatus 1000 from being frequently switched even if the graph 101 frequently crosses the luminance threshold 103. Further, such an operation can increase the probability that the luminance value of the subject is stably below the luminance threshold value 103. Such an operation is also effective when there is an influence of flicker of illumination such as a fluorescent lamp.

  Then, the CPU 26 instructs the optical filter driving circuit 24 to remove the optical filter 4 from the optical path of the imaging optical system 2 when the time reaches t2 when the delay time set in the timing circuit 22 elapses. Thereby, the imaging device 1000 performs infrared imaging. The luminance value of the subject at this time (time t2) is point B.

  As described above, in this embodiment, the user causes the imaging apparatus 1000 to transmit an automatic insertion / removal command in which an adjustment value related to insertion / removal of the optical filter 4 is described by operating the client apparatus 2000. Can do. Here, the adjustment value includes an adjustment value indicating the luminance of the subject and an adjustment value indicating the delay time.

  As a result, the imaging apparatus 1000 that has received the automatic insertion / removal command frequently inserts and removes the optical filter 4 with respect to the optical path of the imaging optical system 2 even when the luminance value of the subject is near the luminance threshold. Can be prevented. In addition, the imaging apparatus 1000 can prevent frequent insertion / removal of the optical filter 4 with respect to the optical path of the imaging optical system 2 even when the luminance of the subject frequently changes due to lighting flicker or the like. it can.

  Next, FIG. 6 is a diagram for explaining a typical command sequence for setting an adjustment value related to insertion / removal of the optical filter 4 between the imaging apparatus 1000 and the client apparatus 2000 according to the present embodiment. It is a sequence diagram. In FIG. 6, ITU-T Recommendation Z. The transaction of this command is described using a so-called message sequence chart defined in the 120 standard.

  Note that the transaction in this embodiment refers to a pair of a command transmitted from the client apparatus 2000 to the imaging apparatus 1000 and a response that the imaging apparatus 1000 returns to the client apparatus 2000 in response thereto. In FIG. 6, it is assumed that the imaging apparatus 1000 and the client apparatus 2000 are connected via an IP network 1500.

  First, through a GetServices transaction, the client device 2000 can acquire the types of Web services supported (provided) by the imaging device 1000 and the address URI for using each Web service.

  Specifically, the client apparatus 2000 transmits a GetServices command to the imaging apparatus 1000. With this command, the client apparatus 2000 acquires information indicating whether or not the imaging apparatus 1000 supports Imaging Service in order to determine whether or not the imaging apparatus 1000 can execute an automatic insertion / removal command or the like. be able to.

  On the other hand, the imaging apparatus 1000 that has received this command returns a response to this command. In the present embodiment, this response indicates that the imaging apparatus 1000 supports Imaging Service. The Imaging Service is a service for performing settings related to insertion / removal of the optical filter 4.

  Next, through a GetVideoSources transaction, the client apparatus 2000 acquires a list of VideoSources stored in the imaging apparatus 1000.

  Here, the VideoSource is a set of parameters indicating the performance of one image sensor 6 included in the image capturing apparatus 1000. For example, the VideoSource includes a VideoSourceToken that is an ID of the VideoSource, and a Resolution indicating the resolution of the captured image that can be output by the image sensor 6.

  The client apparatus 2000 transmits a GetVideoSources command to the imaging apparatus 1000. With this command, the client apparatus 2000 can acquire a VideoSourceToken indicating a VideoSource that can be set for insertion / removal of the optical filter 4.

  Then, the imaging apparatus 1000 that has received the GetVideoSources command returns a response to this command to the client apparatus 2000. In the present embodiment, this response includes a VideoSourceToken indicating a VideoSource corresponding to the image sensor 6.

  Next, with the GetOptions transaction, the client apparatus 2000 can obtain information indicating a command that can be executed by the imaging apparatus 1000 among the insertion command, the removal command, and the automatic insertion / removal command from the imaging apparatus 1000. . Also, with this transaction, the client apparatus 2000 can acquire information indicating adjustment values that can be described in the automatic insertion / removal command.

  The client apparatus 2000 transmits a GetOptions command to the imaging apparatus 1000 (more specifically, an address URI for using the Imaging Service of the imaging apparatus 1000). This command includes VideoSourceToken included in the response of GetVideoSource received from the imaging apparatus 1000.

  On the other hand, the imaging apparatus 1000 that has received this command returns a response to this command to the client apparatus 2000. In this example, this response includes IRCutFilterOptions.

  In this IRCutFilterOptions, information indicating commands that can be executed by the imaging apparatus 1000 among the insertion command, the extraction command, and the automatic insertion / removal command is described. Further, in the IRCutFilterOptions, information indicating adjustment values that can be executed (set) by the imaging apparatus 1000 among the adjustment values that can be described in the automatic insertion / removal command is described.

  Next, the client device 2000 can acquire information indicating the insertion / removal state of the optical filter 4 with respect to the optical path of the imaging optical system 2 from the imaging device 1000 by a transaction of GetImagingSettings.

  The client apparatus 2000 transmits a GetImagingSettings command to an address URI for using the ImagingService of the imaging apparatus 1000. This command includes VideoSourceToken included in the response of GetVideoSource received from the imaging apparatus 1000.

  On the other hand, the imaging apparatus 1000 that has received this command returns a response to this command. In this embodiment, this response includes IRCutFilter Settings.

  In this IRCutFilter Settings, information indicating whether the optical filter 4 is currently inserted in the optical path of the imaging optical system 2 or whether the optical filter 4 is currently removed from this optical path is described. In the present embodiment, the IRCutFilterSettings describes information indicating that the optical filter 4 is currently inserted in the optical path of the imaging optical system 2.

  Next, the client apparatus 2000 causes the imaging apparatus 1000 to automatically control insertion / removal of the optical filter 4 with respect to the optical path of the imaging optical system 2 through a transaction of SetImagingSettings.

  The client apparatus 2000 transmits a SetImagingSettings command to an address URI for using the ImagingServices of the imaging apparatus 1000. This command includes VideoSourceToken included in the response of GetVideoSource received from the imaging apparatus 1000.

  Further, in this command, an adjustment command describing information (IrCutFilter field having a value of “AUTO”) indicating that the imaging apparatus 1000 automatically controls insertion / removal of the optical filter 4 with respect to the optical path of the imaging optical system 2. It is. In addition, an adjustment value (IrCutFilterAutoAdjustment field) is described in this command.

  The IrCutFilter field and the IrCutFilterAutoAdjustment field will be described later.

  On the other hand, the imaging apparatus 1000 that has received this command returns a response of SetImagingSettings to the client apparatus 2000. This response argument is omitted. Here, this response in which the argument is omitted indicates that the execution of this command by the imaging apparatus 1000 is successful.

  Thereby, the imaging apparatus 1000 automatically determines whether the optical filter 4 is inserted into the optical path of the imaging optical system 2 or whether the optical filter 4 is removed from the optical path of the imaging optical system 2.

  Next, FIG. 8 is a flowchart for explaining the GetOptionsResponse transmission process in the imaging apparatus 1000 according to the present embodiment. This process is executed by the CPU 26. When the CPU 26 receives a GetOptions command from the client apparatus 2000 via the I / F 14, the CPU 26 starts executing this process.

  Hereinafter, the flowchart shown in FIG. 8 will be described with reference to FIG. 7 as appropriate. Here, FIG. 7 is a diagram illustrating an example of the GetOptionsResponse transmitted in the GetOptionsResponse transmission process of FIG.

  In step S601, the CPU 26 generates a GetOptions response and stores the generated GetOptions response in the EEPROM 28.

  In step S602, the CPU 26 sets ON, OFF, and AUTO to the value of the IrCutFilterModes field of the GetOptions response stored in the EEPROM 28 in step S601.

  As a result, as shown in FIG. 7, three <img20: IrCutFilterModes> tags are associated with the <ImagingOptions20> tag in the GetOptions response. Furthermore, each of the three <Img20: IrCutFilterModes> tags is associated with ON, OFF, and AUTO.

  Note that the IrCutFilterModes field whose value is ON indicates that the imaging apparatus 1000 can accept an insertion instruction command. An IrCutFilterModes field whose value is OFF indicates that the imaging apparatus 1000 can accept a removal instruction command. Further, the IrCutFilterModes field whose value is AUTO indicates that the imaging apparatus 1000 can accept an automatic insertion / removal command.

  In step S603, the CPU 26 sets Common, ToOn, and ToOff to the value of the Mode field of the GetOptions response stored in the EEPROM 28 in step S601.

  Accordingly, as shown in FIG. 7, three <Img20: Mode> are associated with the <IrCutFilterAutoAdjustmentOptions> tag in the GetOptions response. Furthermore, each of the three <Img20: Mode> tags is associated with Common, ToOn, and ToOff.

  The Mode field whose value is ToOn indicates that the imaging apparatus 1000 can individually use the individual adjustment value for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2. The Mode field whose value is ToOff indicates that the individual adjustment value can also be used individually for determining whether or not the imaging apparatus 1000 removes the optical filter 4 from the optical path of the imaging optical system 2.

  Further, the Mode field having the value Common is common and common for each of the determination whether the imaging apparatus 1000 inserts the optical filter 4 into the optical path of the imaging optical system 2 and whether the extraction is performed or not. Indicates that the value can be used.

  For example, a GetOptions response in which a Mode field whose value is Common is described, a Mode field whose value is ToOn, and a Mode field whose value is ToOff is not described indicates the following.

  That is, the adjustment value used by the imaging apparatus 1000 can be commonly set for each of the case where the optical filter 4 is inserted into the optical path of the imaging optical system 2 and the case where the optical filter 4 is removed from the optical path of the imaging optical system 2. It can be done.

  Further, for example, a GetOptions response in which a Mode field having a value of Common is not described, a Mode field having a value of ToOn, and a Mode field having a value of ToOff is described as follows.

  That is, the adjustment value used by the imaging apparatus 1000 can be set separately for each of the case where the optical filter 4 is inserted into the optical path of the imaging optical system 2 and the case where the optical filter 4 is removed from the optical path of the imaging optical system 2. It can be done.

  In step S604, the CPU 26 sets true to the value of the BoundaryOffset field of the GetOptions response stored in the EEPROM 28 in step S601. Further, the CPU 26 sets PT0S as the value of the Min field of the GetOptions response stored in the EEPROM 28 in step S601, and sets PT30M as the value of the Max field of this response.

  As a result, as shown in FIG. 7, the <img20: BoundaryOffset> tag is associated with the <IrCutFilterAutoAdjustmentOptions> tag in the GetOptions response. Furthermore, an <img20: ResponseTime> tag is associated with the <IrCutFilterAutoAdjustmentOptions> tag.

  The <img20: BoundaryOffset> tag is associated with true. The <img20: ResponseTime> tag is associated with the <img20: Min> tag and the <img20: Max> tag. Here, PT0S is associated with the <img20: Min> tag. Also, PT30M is associated with this <img20: Max> tag. The time set in the value of the ResponseTime field corresponds to a value related to the delay time when the optical filter 4 is inserted and removed.

  Note that a BoundaryOffset field whose value is true indicates that BoundaryOffset can be set in the imaging apparatus 1000. Moreover, a small value (shortest time) is shown. The <img20: Max> tag indicates the maximum time (longest time) that can be set in the ResponseTime field.

  That is, <img20: Min> and <img20: Max> indicate a time range that can be set in the ResponseTime field.

  In step S605, the CPU 26 instructs the I / F 14 to transmit the GetOptions response stored in the EEPROM 28 in step S601 to the client device 2000.

  Next, FIG. 9 is a diagram illustrating an example of the configuration of the SetImagingSettings command. In SetImagingSettings shown in FIG. 9, AUTO is set in the value of the IrCutFilter field. More specifically, in the SetImagingSettings command, AUTO is associated with the <IrCutFilter> tag.

  Note that these tables are stored in the EEPROM 28. The luminance values of the subjects in the tables 1401, 1402, and 1403 are the luminance values acquired from the luminance measurement circuit 18.

  In the ToOn table 1401, the value “−1 (−1.0)” of the Boundary Offset is associated with the luminance value “50” of the subject. Here, in the ToOn table 1401, as the value of BoundaryOffset increases, the luminance value of the subject associated with this value also increases.

  In step S1101, the CPU 26 reads a SetImagingSettings command from the EEPROM 28.

  In step S1102, the CPU 26 determines the value of the BoundaryType field in the command read in step S1101. Specifically, it is determined whether a BoundaryType field whose value is Common, a BoundaryType field whose value is ToOn, and a BoundaryType field whose value is ToOff are described. In this case, a plurality of cases may be described.

  If the CPU 26 determines that only the BoundaryType field whose value is Common is described, the process proceeds to step S1103.

  If it is determined that only the BoundaryType field whose value is ToOn and the BoundaryType field whose value is ToOff are described, the process proceeds to step S1107.

  If it is determined that the BoundaryType field whose value is Common, the BoundaryType field whose value is ToOn, and the BoundaryType field whose value is ToOff are described, the process proceeds to step S1113.

To do.

  In step S1103, the CPU 26 reads the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is Common in the command read in step S1101. In the case of the command shown in FIG. 9, the CPU 26 reads 0.52 as the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is Common.

  In step S <b> 1104, the CPU 26 reads out the respective luminance threshold values from the common conversion table 1403 when turning on and off, and stores them in the EEPROM 28.

  More specifically, first, the CPU 26 reads the luminance value of the subject associated with step S110 in the common conversion table 1403. Next, the CPU 26 stores the read luminance value of the subject in the EEPROM 28 as a luminance threshold value used for determining whether or not the optical filter 4 is inserted and removed from the optical path of the imaging optical system 2.

  In step S <b> 1105, the CPU 26 reads the value of ResponseTime when turning on and off, and stores the delay time in the EEPROM 28.

  More specifically, the CPU 26 stores the value of ResponseTime corresponding to the value read in step S1103 in the EEPROM 28 as a delay time when the optical filter 4 is inserted and removed from the optical path of the imaging optical system 2.

  In step S <b> 1106, the CPU 26 instructs the I / F 14 to transmit a response of SetImagingSettings to the client device 2000.

  In step S1107, the CPU 26 reads the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is ToOn in the command read in step S1101. In the case of the command shown in FIG. 10, the CPU 26 reads out 0.16 as the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is ToOn.

  In step S1108, the CPU 26 reads the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is ToOff in the command read in step S1101. In the case of the command shown in FIG. 9, the CPU 26 reads 0.25 as the value of BoundaryOffset corresponding to the BoundaryType field whose value is ToOff.

  In step S <b> 1109, the CPU 26 reads the luminance threshold value from the ToOn conversion table 1401 and stores it in the EEPROM 28.

  More specifically, first, the CPU 26 reads the luminance value of the subject associated with step S1107 in the conversion table 1401 for ToOn. Next, the CPU 26 stores the read luminance value of the subject in the EEPROM 28 as a luminance threshold value used for determining whether or not the optical filter 4 is inserted in the optical path of the imaging optical system 2.

  In step S1110, the CPU 26 reads the value of ResponseTime and stores the delay time in the EEPROM 28.

  More specifically, the CPU 26 stores the value of ResponseTime corresponding to the value read in step S1107 as the delay time when the optical filter 4 is inserted in the optical path of the imaging optical system 2 in the EEPROM 28.

  In step S <b> 1111, the CPU 26 reads the luminance threshold value from the ToOff conversion table 1402 and stores it in the EEPROM 28.

  More specifically, first, the CPU 26 reads the luminance value of the subject associated with step S1108 in the ToOff conversion table 1402. Next, the CPU 26 stores the read luminance value of the subject in the EEPROM 28 as a luminance threshold value used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2.

  In step S1112, the CPU 26 reads the value of ResponseTime from the ToOff conversion table 1402 and stores it in the EEPROM 28, and then proceeds to step S1106.

  More specifically, the CPU 26 stores the value of ResponseTime corresponding to the value read in step S1108 in the EEPROM 28 as a delay time when removing the optical filter 4 from the optical path of the imaging optical system 2.

  In step S1113, the CPU 26 determines the field value described earlier in the described field value in the command read in step S1101. Specifically, the field value described first in the BoundaryType field whose value is Common, the BoundaryType field whose value is ToOn, and the BoundaryType field whose value is ToOff is determined.

  If the CPU 26 determines that the BoundaryType field whose value is Common is described first, the process proceeds to step S1103.

  If the CPU 26 determines that the BoundaryType field with the value ToOn or the BoundaryType field with the value ToOff is described first, the CPU 26 advances the process to step S1107.

  As described above, this embodiment assumes the following case.

  There is a case where a SetImagingSettings command in which all of the BoundaryType fields having the value “Common”, the value “ToOn”, and the value “ToOff” are described is transmitted.

  This is because it is possible that a SetImagingSettings command in which such three BoundaryType fields are described from a client device conforming to the ONVIF standard is frequently transmitted.

  In such a case, the imaging apparatus 1000 according to the present exemplary embodiment performs processing by determining which of the three described BoundaryType fields is to be used. As an effect, it is possible to increase the degree of freedom in setting the luminance level and delay time of the subject of the imaging apparatus. In addition, it is appropriately set between a plurality of different manufacturer products as intended by the user.

  As a result, it can be prevented that the optical filter 4 is inserted into the optical path of the imaging optical system 2 even though the luminance of the subject is low, and the subject of the captured image is blacked out. In addition, it is possible to prevent the subject of the captured image from being blown out because the optical filter 4 is removed from the optical path of the imaging optical system 2 in spite of the high luminance of the subject.

  In the present embodiment, in step S1113, the CPU 26 determines the field value described first among the described field values in the command read out in step S1101, and performs the process accordingly. However, it is not limited to this. For example, in step S1113, the CPU 26 may determine the field value described later in the command read out in step S1101 and perform processing according to the field value.

  In this embodiment, the CPU 26 determines the order of the described field values among the described field values in the command read out in step S1101, and performs processing according to the order. However, the present invention is not limited to this. It is not something.

  For example, information indicating field values that are preferentially used among field values that can be described in the command read in step S1101 is stored in the EEPROM 28 in advance. An example of such information is the priority added to each field value that can be described in the command read in step S1101.

  Of course, the CPU 26 may perform processing according to the description of one of the field values of Common and ToOn / ToOff based on the priority order.

  In this embodiment, the CPU 26 determines the order of the described field values among the described field values in the command read out in step S1101, and performs processing according to the order. However, the present invention is not limited to this. It is not something.

  For example, the user may be able to set the priority order of field values to be used preferentially. Specifically, a priority setting check box or the like is arranged as a GUI component of the client apparatus 2000. Then, when this check box is selected by the user, a priority order may be set for the imaging apparatus 1000.

  This setting information is stored in the EPPROM 28 or the like of the imaging apparatus 1000 via a network. Of course, the CPU 26 may perform processing in accordance with the description of any one of the field values of Common, ToOn, and ToOff based on the priority order stored in the EPPROM 28.

  Further, the same applies when the field value of Common and the field value of only one of ToOn or ToOff are described. Specifically, in the operation of insertion and removal, processing is performed in accordance with either of the field values described for operations with overlapping settings, and the field value of Common is determined for operations that do not overlap. You may decide to do it.

Subsequently, Example 2 of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the component same as the above-mentioned Example, and the description may be abbreviate | omitted.

  Here, in the above-described first embodiment, the operation of the imaging apparatus when the value corresponding to the BoundaryType field of Common and ToOn or ToOff is described in the command is exemplified.

  FIG. 14 is a diagram illustrating an example of an IrCutFilterAutoAdjustment setting screen in the client device 2000 according to the present embodiment. This screen is displayed on the display unit 422.

  The optical filter type selection pane 301 in FIG. 14 includes a Common selection check box 303, a ToOn selection check box 305, a ToOff selection check box 307, and a BoundaryOffset setting numerical value box 309.

  The optical filter type selection pane 301 includes a delay time setting numerical value box 311. The optical filter setting pane 315 is provided with a first luminance threshold setting scale 317, a second luminance threshold setting scale 319, a first delay time setting scale 321, and a second delay time setting scale 323. Furthermore, a setting button 325 and a cancel button 327 are provided on the setting screen shown in FIG.

  Here, in the optical filter setting pane 315, the vertical axis indicates the luminance value, and the horizontal axis indicates the delay time. In particular, in the optical filter setting pane 315, the horizontal axis (on the Time axis) indicates a luminance value 0 (zero), and the upper limit (upper end) indicates a normalized luminance value 1.0. Further, the lower limit (lower end) indicates a normalized luminance value −1.0. In the optical filter setting pane 315, the left limit (left end) indicates the delay time 0 (zero).

  FIG. 14 is an example of a setting screen when the optical filter 4 is inserted and removed from the optical path of the imaging optical system 2. That is, the screen in FIG. 14 is a setting screen that is used when a SetImagingSettings command in which a BoundaryType field whose value is Common is described is transmitted to the imaging apparatus 1000.

  A common selection check box 303 in FIG. 14 is selected by the user. For this reason, the second luminance threshold setting scale 319 and the second delay time setting scale 323 are grayed out. That is, the second luminance threshold setting scale 319 and the second delay time setting scale 323 are in an inoperable state.

  The user slides the first brightness threshold setting scale 317 up and down to set the user's desired BoundaryOffset value. When the first brightness threshold setting scale 317 is operated by the user, the value of the Common equivalent in the BoundaryOffset setting numerical value box 309 changes in conjunction with this operation.

  On the other hand, the user can also directly input a value in the Common equivalent part in the BoundaryOffset setting numerical value box 309. Then, when a value is input to the Common equivalent part by the user, the first luminance threshold setting scale 317 moves up and down according to the input value.

  Thus, the user can roughly grasp the value of BoundaryOffset from the position of the first luminance threshold setting scale 317. Furthermore, since this position and the value of the Common equivalent in the BoundaryOffset setting numerical value box 309 are linked, the user can accurately grasp the value of BoundaryOffset by this Common equivalent.

  When the setting button 325 is pressed while the first luminance threshold setting scale 317 is arranged on the Time axis, the client device 2000 transmits a SetImagingSettings command in which the BoundaryOffset field is omitted.

  Similarly, even if the setting button 325 is pressed in a state where 0 (zero) is input to the Common equivalent part of the BoundaryOffset setting numerical value box 309, the client apparatus 2000 transmits the omitted SetImagingSettings command.

  For example, a GUI component for instructing to omit the BoundaryOffset field in the SetImagingSettings command may be separately displayed on the display unit 422.

  Specifically, a BoundaryOffset field omission check box is arranged on the screen of FIG. 14 as such a GUI component. Then, when this check box is selected by the user, the BoundaryOffset field of the SetImagingSettings command may be omitted.

  Also, the user sets the value of ResponseTime desired by the user by sliding the first delay time setting scale 321 left and right. When the first delay time setting scale 321 is operated by the user, the time display of the common equivalent part in the delay time setting numerical value box 311 changes in conjunction with this operation.

  On the other hand, the user can also directly input the time into the Common equivalent part in the delay time setting numerical value box 311. Then, when the user inputs time to the Common corresponding part, the first delay time setting scale 321 moves to the left and right according to the input time.

  It is assumed that the setting button 325 is pressed in a state where the first delay time setting scale 321 is arranged at the left end of the optical filter setting pane 315. In such a case, the client apparatus 2000 transmits a SetImagingSettings command in which the ResponseTime field is omitted.

  Similarly, it is assumed that the setting button 325 is pressed in a state where 0 (zero) is input to all the numerical boxes corresponding to the common in the delay time setting numerical box 311. Even in such a case, the client apparatus 2000 assumes a SetImagingSettings command in which the ResponseTime field is omitted.

  In the present embodiment, the first delay time setting scale 321 is arranged at the left end of the optical filter setting pane 315, or 0 is input to the Common equivalent part of the delay time setting numerical value box 311 so that the ResponseTime field is omitted. Can be instructed. However, the present invention is not limited to this.

  For example, a GUI component for instructing to omit the ResponseTime field in the SetImagingSettings command may be separately displayed on the display unit 422.

  Specifically, a ResponseTime field omission check box is arranged on the screen of FIG. 14 as such a GUI component. Then, when this check box is selected by the user, the ResponseTime field of the SetImagingSettings command may be omitted.

  In addition, the client apparatus 2000 according to the present embodiment may transmit a GetOptions command to the imaging apparatus 1000 before displaying the setting screen illustrated in FIG. 14 on the display unit 422. Then, the client device 2000 may update the setting screen of FIG. 14 displayed on the display unit 422 in accordance with the GetOptions response transmitted from the imaging device 1000.

  Here, this response includes an IrCutFilterAutoAdjustmetOptions field. In this field, the value of the BoundaryType field that can be received by the imaging apparatus 1000 is described.

  Further, in this embodiment, an example related to Common is shown, but the same operation can be performed by operating the ToOn selection check box 305 in FIG. 14 in the same manner even when selected by the user. Further, even when the ToOff selection check box 307 is selected by the user, it can be similarly operated by operating the second luminance threshold setting scale 319, the second delay time setting scale 323, and the like.

  Also, all of the common selection check box 303 and the ToOn selection check box 305 or the ToOff selection check box 307 can be selected at the same time. In such a case, when the setting button 325 is pressed, adjustments according to the three types are transmitted. Next, FIG. 15 is a flowchart for explaining the SetImagingSettings transmission process in the client apparatus 2000 according to the present embodiment.

  This process is executed by the CPU 426. Then, the CPU 426 determines whether or not the setting button 325 has been pressed. If it is determined that the setting button 325 has been pressed, the CPU 426 starts this processing and determines that the setting button 325 has not been pressed. Does not start this processing.

  In step S1201, the CPU 426 generates a SetImagingSettings command and stores the generated SetImagingSettings command in the EEPROM 428. The value of the IrCutFilter field in the stored SetImagingSettings command is AUTO.

  In step S1202, the CPU 426 determines which one of the common selection check box 303, the ToOn selection check box 305, or the ToOff selection check box 307 is selected.

  If the CPU 426 determines that only the common selection check box 303 is selected, the CPU 426 advances the process to step S1203. If the CPU 426 determines that the ToOn selection check box 305 and the ToOff selection check box 307 are selected, the process proceeds to step S1209. If it is determined that the Common selection check box 303, the ToOn selection check box 305, and the ToOff selection check box 307 are selected, the process advances to step S1214.

  In step S1203, the CPU 426 adds a BoundaryType field whose value is Common to the command stored in step S1201.

  In step S1204, the CPU 426 determines whether or not a value is set in the Common equivalent part in the BoundaryOffset setting numerical value box 309. If the CPU 426 determines that a value is set in the Common equivalent part in the BoundaryOffset setting numerical value box 303, the process proceeds to step S1205.

  On the other hand, if the CPU 426 determines that no value is set in the Common equivalent in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1206.

  In step S1205, the CPU 426 adds a BoundaryOffset field to the command stored in step S1201. The value of the BoundaryOffset field is a value set in the Common equivalent part in the BoundaryOffset setting numerical value box 309.

  In step S <b> 1206, the CPU 426 determines whether or not a value is set in a common equivalent part in the delay time setting numerical value box 311. If the CPU 426 determines that a value is set in the Common equivalent in the delay time setting numerical value box 311, the process proceeds to step S <b> 1207.

  On the other hand, if the CPU 426 determines that no value is set in the Common equivalent part in the delay time setting numerical value box 311, the process proceeds to step S1208.

  In step S1207, the CPU 426 adds a ResponseTime field to the command stored in step S1201. The value of the ResponseTime field is a value set in the Common equivalent part in the delay time setting numerical value box 311.

  In step S1208, the CPU 426 instructs the I / F 414 to transmit the command stored in step S1201 to the imaging apparatus 1000. Here, an example of a command including Common, which is a common adjustment value for inserting and removing an optical filter, in the SetImagingSettings command is the SetImagingSettings command illustrated in FIG. 9.

  On the other hand, in step S1209, the CPU 426 adds a BoundaryType field whose values are ToOn and ToOff to the command stored in step S1201.

  In step S <b> 1210, the CPU 426 determines whether values are set in the ToOn and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309. If the CPU 426 determines that values are set in the ToOn and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1211.

  On the other hand, if the CPU 426 determines that values are not set in the ToOn and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1212.

  In step S1211, the CPU 426 adds a BoundaryOffset field to the command stored in step S1201. The value of the BoundaryOffset field is a value set in a portion corresponding to ToOn and ToOff in the BoundaryOffset setting numerical value box 309.

  In step S <b> 1212, the CPU 426 determines whether values are set in the ToOn and ToOff equivalent portions in the delay time setting numerical value box 311. If the CPU 426 determines that values are set in the ToOn and ToOff equivalent parts in the delay time setting numerical value box 311, the process proceeds to step S1213.

  On the other hand, if the CPU 426 determines that values are not set in the ToOn and ToOff equivalent parts in the delay time setting numerical value box 311, the process proceeds to step S1208.

  In step S1213, the CPU 426 adds a ResponseTime field to the command stored in step S1201. The value of the ResponseTime field is a value set in a portion corresponding to ToOn and ToOff in the delay time setting numerical value box 311.

  In step S1208, the CPU 426 instructs the I / F 414 to transmit the command stored in step S1201 to the imaging apparatus 1000.

  Here, an example of a command to be transmitted including ToOn and ToOff, which are individual adjustment values for the case of inserting and removing the optical filter, is the command of SetImagingSettings shown in FIG.

  If it is determined in step S1210 that a value corresponding to ToOn or ToOff is not set in the BoundaryOffset setting numerical value box 309, each field that is not set is not added.

  If it is determined in step S1213 that a value corresponding to ToOn or ToOff is not set in the delay time setting numerical value box 311, the fields are not added for each item that is not set.

  In step S1214, the CPU 426 adds a BoundaryType field whose values are Common, ToOn, and ToOff to the command stored in step S1201. In addition, Common, ToOn, and ToOff are associated with the <BoundaryType> tag and described in this command.

  In step S <b> 1215, the CPU 426 determines whether values are set in the ToOn and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309. If the CPU 426 determines that values are set in the Common, ToOn, and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1216.

  On the other hand, if the CPU 426 determines that values are not set in the Common, ToOn, and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1217.

  In step S1216, the CPU 426 adds a BoundaryOffset field to the command stored in step S1201. The value of the BoundaryOffset field is a value set in the Common, ToOn, and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309.

  In step S <b> 1217, the CPU 426 determines whether values are set in the common, ToOn, and ToOff equivalent portions in the delay time setting numerical value box 311. If the CPU 426 determines that values are set in the Common, ToOn, and ToOff equivalent portions in the delay time setting numerical value box 311, the process proceeds to step S1218.

  On the other hand, if the CPU 426 determines that values are not set in the common, ToOn, and ToOff equivalent portions in the delay time setting numerical value box 311, the process proceeds to step S1208.

  In step S1218, the CPU 426 adds a ResponseTime field to the command stored in step S1201. The value of the ResponseTime field is a value set in a common, ToOn, and ToOff equivalent part in the delay time setting numerical value box 311.

  In step S1208, the CPU 426 instructs the I / F 414 to transmit the command stored in step S1201 to the imaging apparatus 1000.

  Here, an example of the command to be transmitted including the adjustment values Common, ToOn, and ToOff for the case where the optical filter is inserted and the case where it is removed is the command of SetImagingSettings shown in FIG.

  If it is determined in step S1215 that a value corresponding to Common, ToOn, or ToOff is not set in the BoundaryOffset setting value box 309, the addition of each field is not performed for each item that is not set.

  If it is determined in step S1217 that a value corresponding to Common, ToOn, or ToOff is not set in the delay time setting numerical value box 311, the fields are not added for each item that is not set.

  Next, display processing when the client device 2000 receives a GetImagingSettings response will be described with reference to FIG.

  FIG. 17 is a sequence diagram of a typical command for displaying the setting contents between the imaging apparatus 1000 and the client apparatus 2000.

  Here, the display process of the second embodiment will be described with reference to the flowchart of FIG.

  This process is executed by the CPU 426. When the CPU 426 receives a GetImagingSettings command from the imaging apparatus 1000 via the I / F 414, the CPU 426 starts executing this process. Also, the GetImagingSettings command received by the I / F 414 is stored in the EEPROM 428.

  First, in step S <b> 1301, the CPU 426 receives a GetImagingSettings response of the imaging apparatus 1000 in response to the GetImagingSettings command transmitted by the client apparatus 2000.

  In step S1302, the CPU 426 determines whether or not each selection check box in the IrCutFilterAutoAdjustment setting screen is selected by the user.

  If the CPU 426 determines that only the common selection check box 303 has been selected, the CPU 426 advances the process to step S1303. If the CPU 426 determines that the ToOn selection check box 305 and the ToOff selection check box 307 are selected, the CPU 426 advances the process to step S1307. If all of the common selection check box 303, the ToOn selection check box 305 and the ToOff selection check box 307 are selected, the process advances to step S 1311.

  In step S1303, the CPU 426 determines whether the value of BoundaryOffSet of Common is set. If it is set, the process proceeds to step S1304, and if not, the process proceeds to step S1305.

  In step S1304, the CPU 426 displays Common's BoundaryOffset described in the GetImagingSettings response. Here, the value is displayed in the Common equivalent part in the BoundaryOffset setting numerical value box 309 in FIG.

  In step S1305, the CPU 426 determines whether or not the ResponseTime of Common is set.

  If the CPU 426 determines that the Response Time of Common is set, the CPU 426 advances the process to Step S1306. If the CPU 426 determines that the Response Time is not set, the CPU 426 ends the process.

  In step S1306, the CPU 426 displays the Common ResponseTime described in the GetImagingSettings response. Here, the value is displayed in the Common equivalent part in the delay time setting numerical value box 311 in FIG.

  In step S1307, the CPU 426 determines whether the values of BoundaryOffset for ToOn and ToOff are set. If they are set, the process proceeds to step S1308. If not set, the process proceeds to step S1309.

  In step S1308, the CPU 426 displays ToOn and ToOff BoundaryOffset described in the GetImagingSettings response. Here, the value is displayed in a portion corresponding to ToOn and ToOff in the BoundaryOffset setting numerical value box 309 in FIG.

  In step S <b> 1309, the CPU 426 determines whether the response time ToOn and ToOff is set.

  If the CPU 426 determines that the response time of ToOn and ToOff is set, the process proceeds to step S1310. If the CPU 426 determines that the response time is not set, the process ends.

  In step S1310, the CPU 426 displays ToOn and ToOff ResponseTime described in the GetImagingSettings response. The display here is displayed in a portion corresponding to ToOn and ToOff in the delay time setting numerical value box 311 in FIG.

  In step S1311, CPU 426 determines the value of the Mode field of the GetImagingSettings response. If Common is described in the Mode field, the process proceeds to step S1303.

  At this time, BoundaryOffset corresponding to BoundaryOffset of ToOn and ToOff is not displayed. Specifically, as shown in FIG. 14, the CPU 426 grays out the BoundaryOffset setting value box 309 corresponding to ToOn and ToOff to make it inoperable.

  In addition, at this time, ResponseTime corresponding to ResponseTime of ToOn and ToOff is not displayed. Specifically, as shown in FIG. 14, the CPU 426 grays out the delay time setting numerical value box 311 corresponding to ToOn and ToOff to make it inoperable.

  On the other hand, if ToOn and ToOff are described in the Mode field, the process proceeds to step S1307.

  At this time, the BoundaryOffset corresponding to the BoundaryOffset of Common is not displayed. Specifically, the CPU 426 grays out the BoundaryOffset setting numerical value box 309 corresponding to Common to make it inoperable.

  In addition, at this time, the ResponseTime corresponding to the ResponseTime of Common is not displayed. Specifically, the CPU 426 grays out the delay time setting numerical value box 311 corresponding to Common to make it inoperable.

  As described above, this embodiment assumes the following case.

  There is a case in which the external device 2000 transmits a SetImagingSettings command in which all of the BoundaryType fields whose values are Common, ToOn, and ToOff are described.

  Then, the imaging apparatus 1000 determines which setting information is to be used among the three BoundaryType fields described.

  In this case, normally, the client apparatus 2000 cannot know what the determined setting information is. However, the client device 2000 in the present embodiment can receive the setting information via the network. That is, it is possible to know what setting information the imaging apparatus 1000 is operating on.

  As an effect, it is possible to increase the degree of freedom in setting the luminance level and delay time of the subject of the imaging apparatus. In addition, it is possible to appropriately set a plurality of different manufacturer products as intended by the user.

  In this embodiment, when the Common selection check box 303 and the ToOn selection check box 305 or the ToOff selection check box 307 are selected, the client device 2000 notifies a part of the display unit 422 and the like as an inoperable state. . However, the notification to the user is not limited to this. For example, the display unit 422 or the like may be notified to prompt the user to cancel the setting.

  As a specific notification method, a display such as “Duplicate setting” or “Release setting of one” may be performed for a predetermined time, or the other setting item may be blinked for a predetermined time. .

  Further, when there is a difference between the setting information set by the client apparatus 2000 and the setting information received from the imaging apparatus 1000, the client apparatus 2000 may display a notification that prompts the display unit 422 to cancel the value setting.

  As a specific notification method, display such as “setting changed” or “setting updated” may be performed for a predetermined time, or the other setting item may blink for a predetermined time.

  Note that the IrCutFilterAutoAdjustment setting screen in the present embodiment corresponds to a user interface unit for inputting values such as the BoundaryOffset field described in the SetImagingSettings command.

  Further, in this embodiment, the operation of receiving the setting information of the image capturing apparatus 1000 by the response of the GetImagingSettings command is exemplified. However, the setting information may be received by other methods. For example, it can be received by using an event command or the like.
