For such time management, for example, a GPS (Global Positioning System) function of a mobile phone is used.

Embodiments of the present invention will be described below with reference to the drawings.
[Example 1]
FIG. 1A and FIG. 1B are conceptual diagrams showing the configuration of a system including a mobile phone according to Embodiment 1 of the present invention. Here, in the example of FIG. 1A, shooting execution instruction information is transmitted from the mobile phone 100a that does not have a shooting function to the mobile phones 100b and 100c that have two shooting functions. This is an example in which the telephones 100b and 100c are simultaneously released. In the example of FIG. 1B, shooting execution instruction information is transmitted from one mobile phone 100a having a shooting function to one mobile phone 100b having a shooting function. This is an example in which the telephones 100a and 100b are simultaneously released. Note that, here, simultaneous release by a mobile phone having two shooting functions is described assuming stereo shooting, but the number of mobile phones is not limited to two. The shooting execution instruction information serves as a shooting trigger signal, as is apparent from the above description.

  Here, in the systems of FIGS. 1A and 1B, the mobile phone 100a on the side that transmits the shooting execution instruction information is referred to as the “master side” mobile phone for convenience, and the mobile phones 100b and 100c that are the destinations. Is called a “slave side” mobile phone.

  Next, with reference to FIG. 2, the internal configuration of these mobile phones will be described. Here, it is assumed that there is no structural difference between the mobile phone on the master side and the mobile phone on the slave side. Further, the mobile phone 100a on the master side in FIG. 1 (a) does not have a photographing function, and the basic configuration conforms to the configuration in FIG.

  That is, the mobile phone 100 includes a microphone 101, an analog / digital (AD) conversion unit 102, a digital signal processing unit 103, a control unit (CPU) 104, an operation switch unit 105, a modulation unit 106, and a transmission unit. 107, an antenna unit 108, a reception unit 109, a demodulation unit 110, a digital / analog (DA) conversion unit 111, a speaker 112, a photographing unit 113, a recording unit 114, and a display unit 115. Has been.

  Here, since the well-known thing can be utilized for these structures, the detailed description is abbreviate | omitted and it demonstrates easily below.

  The microphone 101 is a voice input unit for inputting voice from the user. That is, the user's voice is converted into an electric signal (voice signal) by the microphone 101 during a call. The audio signal is input to the AD conversion unit 102 and converted into a digital signal, and then input to the digital signal processing unit 103 and compressed (encoded) into a format suitable for subsequent communication. Then, the compressed signal is modulated by the modulation unit 106. Thereafter, the modulated signal is subjected to processing such as signal amplification and noise removal in the transmission unit 107. Then, the sound is transmitted as a radio frequency signal from the antenna unit 108 via the base station 300 to a predetermined transmission destination.

  On the other hand, when audio is transmitted from another mobile phone as a radio frequency signal, it is received by the receiving unit 109 via the antenna unit 108. The receiving unit 109 performs processing such as amplification of received signals and noise removal. Thereafter, this signal is demodulated in the demodulator 110. The demodulated signal is expanded (decoded) by the digital signal processing unit 103, converted to an analog audio signal by the DA conversion unit 111, and the audio is output via the speaker 112.

  The mobile phone 100 has a photographing function. The photographing unit 113 includes a photographing lens, an image sensor, and the like. During the release operation, in the photographing unit 113, an image of a subject (not shown) that has entered through the photographing lens is converted into an electrical signal by the image sensor. Thereafter, the electrical signal is converted into a digital signal and output to the digital signal processing unit 103. The digital signal processing unit 103 performs image processing such as color signal generation processing, white balance adjustment processing, and matrix conversion processing, and then compresses the signal in a format suitable for recording. Then, this compressed signal is recorded in the recording unit 114. It is also possible to display an image processed by the digital signal processing unit 103 on a display unit 115 constituted by an LCD (Liquid Crystal Display) or the like, or to transmit it to another mobile phone by communication.

  Note that data communicated via the antenna unit 108 is not limited to data related to sound and images. In particular, in the first embodiment, signals such as shooting execution instruction information, a pseudo trigger signal, and a response signal are communicated with other mobile phones at the time of simultaneous shooting described in detail later.

  The above control is centrally controlled by the control unit (CPU) 104. The CPU 104 executes control according to a predetermined program based on the operation state of the operation switch unit 105 operated in conjunction with an operation button (not shown) provided outside the mobile phone. In addition to what is normally used in conventional mobile phones, this program includes a program for performing control on the mobile phone on the master side and a program for performing control on the mobile phone on the slave side during simultaneous shooting. There is.

  The operation switch unit 105 includes a switch that operates in conjunction with a numeric button when making a call, a switch that operates in conjunction with a release button for instructing execution of shooting, and a shooting mode at the time of shooting for stereo shooting. And a switch that operates in conjunction with a mode switching button for switching to the stereo shooting mode.

  Next, as an example of simultaneous shooting using the mobile phone having such a configuration, a case of performing stereo shooting will be described. The example described here is an example in which photographing is simultaneously performed by the master-side mobile phone and the slave-side mobile phone shown in FIG.

  At the time of stereo shooting, shooting is performed with two cameras placed with the mobile phone separated by a distance between human eyes. In this state, the shooting mode of at least one of the mobile phones is set to the stereo shooting mode and stereo shooting is started. In the first embodiment, stereo shooting is started by depressing the release button of one of the mobile phones. Alternatively, one mobile phone set in the stereo mode may be called from the other mobile phone, and stereo shooting may be started when line connection is established.

  Here, the cellular phone on the side on which the release button is pushed down or the cellular phone on the side on which the telephone call is made becomes the above-described cellular phone 100a on the master side. First, the CPU of the mobile phone 100a on the master side starts the control shown in the flowchart of FIG.

  That is, in FIG. 3, in order to determine the photographing time (release timing) of the two mobile phones, processing for determining the delay time ΔT is performed. This ΔT is a time during which the photographing execution instruction information can be reliably transmitted from the master-side mobile phone 100a to the slave-side mobile phone 100b.

  In order to determine this delay time ΔT, the mobile phone 100a on the master side transmits a pseudo trigger signal to the mobile phone 100b on the slave side (step S1). Here, the pseudo trigger signal is a signal having a small data capacity in which transmission destination information, transmission source information, and information indicating that this signal is a pseudo trigger signal for stereo shooting are recorded at least.

  After transmitting such a pseudo trigger signal, the master-side mobile phone 100a determines whether or not a response signal has been received from the slave-side mobile phone 100b (step S2), and waits until the response signal is received. .

  If it is determined in step S2 that a response signal has been received, the master mobile phone 100a calculates a delay time ΔT (step S3). This delay time ΔT is 1/2 of the time τ from when the pseudo trigger signal shown in the timing chart of FIG. 4 is transmitted until the response signal is received (that is, the pseudo trigger signal is received by the mobile phone 100b on the slave side). Is equivalent to the time until) and a certain amount of margin α is added. When τ is short, the delay time Δt = τ may be set.

  In other words, the delay time Δt assumes a so-called release time lag indicating “delay from transmission of shooting execution instruction information, that is, trigger signal to shooting execution timing” that will occur at the time of actual shooting to be performed. Of course, it is conceivable that the state of the line changes during communication. Therefore, the delay time ΔT is calculated periodically, and the shooting time information is updated when the delay time ΔT changes significantly. Needless to say, it is more preferable.

  After calculating the delay time ΔT in step S3, the mobile phone 100a on the master side determines whether or not the delay time ΔT is longer than a predetermined time (for example, 0.5 seconds) (step S4). As a result of the determination in step S4, if it is determined that the delay time ΔT is shorter than the predetermined time, there is no particular problem, so the control of this flowchart is terminated as it is.

  On the other hand, as a result of the determination in step S4, if it is determined that the delay time ΔT is longer than the predetermined time, it is highly likely that the photographer misses the photo opportunity and the intended shooting is not performed. Therefore, the master mobile phone 100a displays a warning on the display unit 115 (step S5), and then ends the control of this flowchart. Here, it goes without saying that the warning is not limited to display but may be a voice warning or the like. Further, instead of issuing such a warning, the delay time ΔT may be displayed, or the subsequent photographing itself may be prohibited.

  Next, control performed in the CPU of the mobile phone 100b on the slave side will be described with reference to FIG. That is, in this flowchart, the mobile phone 100b on the slave side determines whether or not a pseudo trigger signal is received from the mobile phone 100a on the master side (step S11), and waits until the pseudo trigger signal is received. On the other hand, if it is determined in step S11 that the pseudo trigger signal has been received, the slave mobile phone 100b transmits a response signal to the master mobile phone 100a (step S12).

  After the delay time is determined by such control, simultaneous release of two mobile phones is executed. Next, the control performed by the master-side mobile phone 100a during the simultaneous release will be described with reference to FIG.

In FIG. 6, the mobile phone 100a on the master side determines shooting time information for making the shooting times of two mobile phones simultaneous, and generates shooting execution instruction information based on the shooting time information. The photographing execution instruction information is transmitted to the mobile phone 100b on the slave side (step S21). Here, the shooting time information is a time t ₂ (= t ₁ + ΔT) obtained by adding a delay time ΔT to the current time t ₁ measured by the GPS shown in FIG.

  Next, the mobile phone 100a on the master side determines whether or not the shooting time determined in step S21 has been reached (step S22), and waits until the shooting time is reached. On the other hand, when it is determined in step S22 that the photographing time has come, the master-side mobile phone 100a performs a release operation (step S23). Thereafter, a predetermined file name is given to the captured image and recorded in the recording unit 114.

  At the time of this image recording, a code indicating whether the image file to be recorded is an image taken from the left or right viewpoint, or an image file acquired by the mobile phone 100b on the slave side and this image file are a pair of image files. It is more preferable to record a code indicating that it exists. Further, if the shooting time is recorded at the same time, the user can determine whether or not two mobile phones have shot simultaneously.

  Next, control in the mobile phone 100b on the slave side will be described with reference to FIG. The slave-side mobile phone 100b determines whether or not the shooting execution instruction information is received from the master-side mobile phone 100a (step S31), and waits until receiving the shooting execution instruction information. On the other hand, if it is determined in step S31 that the shooting execution instruction information has been received, it is determined whether or not the shooting time has come based on the shooting time information included in the shooting execution instruction information (step S31). S32), waiting until the shooting time comes. On the other hand, when it is determined in step S32 that the shooting time has come, the mobile phone 100b on the slave side performs a release operation (step S33). Thereafter, the same image recording as that of the mobile phone 100a on the master side is performed.

  Here, after the end of image recording, the time when the release on the slave side is executed may be transmitted to the mobile phone 100a on the master side as shooting start time information. If it is configured such that such information can be received by the mobile phone 100a on the master side, it can be determined whether or not release has been executed simultaneously on the master side and the slave side. As a result, when the photographing is not performed at the same time, a warning may be given in the mobile phone 100a on the master side.

  Further, as in the example of FIG. 1A, when there are two or more mobile phones on the slave side, the same control as in the case of using one mobile phone may be performed on the two mobile phones. However, in this case, it is necessary to use a three-party simultaneous call mode or the like as a communication mode. That is, if the shooting execution instruction information is transmitted to both of the two mobile phones on the slave side, stereo shooting can be performed even if the mobile phone on the master side does not have a shooting function.

  Further, after the photographing is completed, the image data may be communicated to synthesize the left and right images with any of the mobile phones. Furthermore, shooting information such as exposure conditions may be included in the shooting execution instruction information.

  As described above, according to the first embodiment, the shooting time is determined in consideration of the line condition, and based on this, the shooting execution instruction is transmitted to the mobile phone on the slave side. The release operation can be performed simultaneously on the master side and the slave side. That is, stereo shooting can be performed without providing a dedicated mechanism or the like for the two mobile phones.

[Example 2]
Next, a second embodiment of the present invention will be described. The second embodiment is different from the first embodiment in the delay time calculation method. Note that the configuration and control at the time of simultaneous photographing are the same as those described in the first embodiment, and thus the description thereof is omitted.

First, control in the master-side mobile phone 100a will be described with reference to FIG. In FIG. 9, the mobile phone 100a of the master side transmits a pseudo trigger signal to the slave side of the mobile phone 100b, it is recorded in a memory (not shown) of the CPU to detect the transmission time t ₃ at this time (Step S41). Next, the master-side mobile phone 100a determines whether or not a response signal has been received from the slave-side mobile phone 100b (step S42), and waits until a response signal is received.

On the other hand, the mobile telephone 100b on the slave side detects the time t ₄ when receiving a pseudo trigger signal from the master, the master-side of the mobile phone 100a, including the data of the time t ₄ in reply signal Send. When determining that the response signal is received in the determination in step S42, the master-side mobile phone 100a calculates the delay time ΔT (step S43). This delay time ΔT is obtained by adding a slight margin α to the time (t ₄ −t ₃ ) between the transmission time t ₃ of the pseudo trigger signal and the reception time t ₄ of the response signal shown in the timing chart of FIG. Time. Needless to say, the delay time ΔT should be calculated periodically. For the calculation of t ₄ -t ₃ , the master side transmits the pseudo trigger signal including the data at time t ₃ to the slave side, the slave side performs the calculation, and the result is included in the response signal and returned. May be.

  After calculating the delay time ΔT in step S43, the master mobile phone 100a determines whether or not the delay time ΔT is longer than a predetermined time (for example, 0.5 seconds) (step S44). As a result of the determination in step S44, when it is determined that the delay time ΔT is shorter than the predetermined time, the control of this flowchart is ended.

  On the other hand, when it is determined that the delay time ΔT is longer than the predetermined time as a result of the determination in step S4, the mobile phone 100a on the master side displays a warning on the display unit 115 (step S45). End control. As in the first embodiment, instead of giving a warning, the delay time ΔT may be displayed, or the subsequent photographing itself may be prohibited.

  Next, control performed in the CPU of the mobile phone 100b on the slave side will be described with reference to FIG. That is, in this flowchart, the mobile phone 100b on the slave side determines whether or not a pseudo trigger signal is received from the mobile phone 100a on the master side (step S51), and waits until the pseudo trigger signal is received. On the other hand, if it is determined in step S51 that the pseudo trigger signal has been received, the mobile phone 100b on the slave side sends a response signal recording the reception time of the pseudo trigger signal at this time to the mobile phone 100a on the master side. Transmit (step S52).

  As described above, according to the second embodiment, the delay time can be calculated by comparing absolute times.
