Description

  The present invention relates to an imaging apparatus, and more particularly to an imaging apparatus having a plurality of interfaces with external devices.

  High-definition in video equipment such as television is progressing, and high-definition systems that double the resolution of conventional NTSC and other television systems are spreading. Corresponding to this, the number of pixels of the image pickup apparatus has increased, and an image pickup apparatus for high vision has been developed. Such high-definition image pickup apparatuses are generally capable of picking up high-resolution still images as well as high-definition moving images.

  Such an imaging apparatus requires a digital interface that transmits and receives a compressed digital signal to and from the external device as an interface with the external device. In addition, a high-speed digital interface for outputting high-definition signals in real time is required.

  Conventionally, for example, USB (Universal Serial Bus) is known as such an interface in the former example. USB can input and output compressed image data by connecting an imaging device and a personal computer, for example.

  For example, HDMI is known as an interface for real-time transmission of the latter high-definition video. The HDMI interface can be used as an interface for connecting an imaging device and, for example, a high-definition monitor and transmitting video in real time.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
A first embodiment of the present invention will be described. FIG. 1 is a block diagram showing a configuration of an imaging apparatus according to the present invention. 100 is an image sensor, 102 is an AD converter circuit, 103 is a signal processing circuit, 108 is a control circuit, 104 is a first interface circuit, 105 is a second interface circuit, and 106 and 107 are connectors for connecting external devices. It is.
Reference numeral 108 denotes a control circuit, and reference numeral 109 denotes a memory such as an SDRAM (Synchronous Dynamic Random Access Memory). The display unit 110 is a display device such as a liquid crystal display, and displays video signals such as captured and recorded moving images and still images, and information on operation menus and recorded data. Reference numeral 112 denotes a recording unit that records data such as a moving image, a still image, and audio on the recording medium 113. The recording medium 113 may be a recording medium such as a hard disk fixed in the imaging apparatus, or a memory card using a semiconductor memory such as a flash memory. An optical disc such as a DVD (Digital Versatile Disc) may be used.
The image sensor 100 converts an optical signal input via an optical system such as a lens (labor saving in FIG. 1) into an electrical signal, and generates a video signal. This imaging apparatus can capture moving images and still images, and can capture high-definition video in the moving image mode. In the still image mode, for example, a still image of 5 million pixels can be captured. The AD conversion circuit 102 converts an analog signal output from the image sensor 100 into a digital signal. Note that an image pickup element in which an AD conversion circuit is incorporated in the element may be used. In such a case, the AD conversion circuit 102 is unnecessary. The signal processing circuit 103 performs processing such as interpolation processing and filtering on the digitized video signal. Further, the signal processing circuit 103 normally performs signal processing by separating the input video signal into RGB three primary color signals, and generates a luminance signal and a color difference signal. Further, the generated luminance signal and color signal are compressed by the signal processing circuit 103 by the encoding method such as MPEG in the moving image mode and JPEG in the still image mode. The compressed image signal generated in this way is recorded in the memory 109. Further, the signal processing circuit 103 may perform different optimum processes on the monitor video signal displayed on the display circuit 110 and the recording video signal. This makes it possible to generate a video signal that matches the characteristics of the internal or external display device that displays each video.
The first interface circuit 104 is an interface circuit for mainly outputting the uncompressed video signal generated by the signal processing circuit 103, and is based on, for example, the HDMI (High Definition Multimedia Interface) standard. The HDMI interface is an interface suitable for transmitting a digital high-definition video signal to an external device in real time. As a result, the high-definition video can be monitored or recorded by the external display device. This signal is generally a high-quality uncompressed signal, but it may be a compressed signal subjected to encoding such as MPEG.
The second interface circuit 105 is an interface circuit for inputting / outputting the compressed video signal generated by the signal processing circuit 102 and other data, and is based on, for example, the USB (Universal Serial Bus) standard. . The USB interface is an interface suitable for transmission / reception of digital data. For example, it can be used when moving digital data such as moving images and still images to a personal computer or other external recording device.
A first connector 106 is connected to the first interface circuit 104, and is connected to an external device via a connection cable. Similarly, a first connector 107 is connected to the second interface circuit 105 and is connected to an external device via a connection cable. In a state in which the external device is connected, the control circuit 108 performs control so that one of the first and second interface circuits is enabled.
FIG. 2 is a diagram showing an example of the appearance of the image pickup apparatus. A (upper left in the figure) is a front view, B (upper right in the figure) is a rear view, and C (lower left in the figure) is a side view. Reference numeral 201 (206) denotes a recording button which is pressed when starting moving image shooting or shooting a still image. It may also function as a movie shooting end button. Reference numeral 203 denotes a lens, and 202 (204) denotes an optical viewfinder. Reference numeral 205 denotes a display unit such as a liquid crystal display. Reference numeral 207 denotes a menu button for menu display and display deletion. By pressing this button, an operation menu can be displayed on the display unit 205. Further, by pressing the menu button 207 while the operation menu is displayed on the display unit 205, the operation menu can be prevented from being displayed.
Reference numerals 208 and 209 are operation buttons. Reference numeral 208 denotes a button for moving the menu item when selecting a menu item in a menu operation to be described later. Reference numeral 208 denotes a button for moving downward. Similarly, selection items can be moved up, down, left and right. (Movement button numbers other than 208 are omitted)
In the side view C, reference numerals 210 and 211 denote connectors for connecting to the first and second external devices, respectively. For example, 210 is a USB connector and 211 is an HDMI connector. It should be noted that a single connector in which these two types of interfaces are used in common can be used as in an embodiment described later. In that case, a single connector (for example, only 210) is used.
Next, the interface switching operation will be described. When the imaging apparatus is connected to an external device, the following operation is performed according to the connected device. First, the case of connecting to a television will be described. In this case, the purpose of connecting to the television is when the user wants to view the captured high-definition video on a large-screen television. For example, it is a case where the whole family sees a video shot during a family trip. At this time, in order to send the high-definition video from the imaging device to the television monitor in real time, the HDMI interface as the first interface is used. FIG. 6 shows an overview when an external device and an imaging device are connected.
When the menu button on the operation unit of the imaging apparatus is pressed, the screen shown in FIG. 3 is displayed on the display unit. On this menu display screen, an interface switching item 301 is selected. In the selection, the above-described operation button 208 or the like is used. When this item is selected, the screen of FIG. 4 is displayed. On this screen, either manual / automatic interface switching can be selected. First, a case where manual is selected will be described. When manual switching 402 is selected, the screen of FIG. 5 is displayed. On this screen, either the first or second interface can be selected. In this example, the first interface is USB and the second interface is HDMI.
Therefore, the user selects USB when he wants to select USB, and selects HDMI when he wants to select HDMI. For example, HDMI is selected when displaying a high-definition video shot on a television monitor. At this time, in the imaging apparatus, the control circuit transmits a control signal to the switching circuit so as to select HDMI. As a result, the switching circuit selects HDMI and the connector is set for the HDMI interface. Thus, when the interface on the imaging apparatus side is viewed from the external device, it operates as an HDMI interface.
When this cable is connected to an external monitor after setting in this way, the same operation as when a normal HDMI interface is connected is performed. When using an HDMI interface to connect an imaging device to an external monitor, in addition to using high-quality moving image video on the external display device, the video is automatically recorded on a recording device such as a hard disk of the external monitor and operated as a monitoring device It is also possible.
Next, a case where it is used as a USB interface will be described. When connecting via a USB interface, when transferring compressed image data from an external device to the imaging device, the data recorded on the imaging device is often sent to the external device. As described above, the USB interface is often used when data is transmitted / received and copied between the external device and the imaging apparatus.
In the above case, as in the case of using the HDMI interface, the manual of the interface switching manual / automatic setting is selected on the screen of FIG. When manual is selected, the screen of FIG. 5 is displayed. On this screen, either the first or second interface can be selected. Therefore, the user selects USB. When USB is selected in this way, the control circuit sets the switching circuit to the USB side, and the connector operates as a USB connector. After setting the USB in this way, it is connected to an external device such as a personal computer. Thus, the imaging device can be used as a USB device. When operating with a USB connection in this way, for example, as shown in FIG. 7, the display portion of the USB is colored so that the user is in which mode the user is operating. Further, for example, as shown in FIG. 8, the display at this time may display the function content such as “data transfer” instead of the interface name such as “USB” so that the user can easily understand the operation content. .
Next, the operation when the user sets the automatic switching mode on the screen of FIG. 4 will be described. When the automatic switching mode is set, it operates as follows.
In this case, the control circuit of the imaging device first sets the switching circuit to the USB mode. The connection with the external device is started in such a connected state. At this time, when communication is started with a predetermined communication protocol, communication is started as it is as a USB device.

  If the communication is not established as the USB device after the fixed time has elapsed, the control circuit recognizes that the external device is not a USB device and switches the communication mode to HDMI. Therefore, communication is started in the same manner. When an external device starts communication as an HDMI host and communication is established, the external device operates in the HDMI mode. In this manner, communication in the HDMI mode is started between the external device and the imaging device.

In the above example, the imaging device initially does not know whether the interface of the external device is HDMI or USB, so first try to connect in USB mode, and in the case of USB, switch the interface setting to USB and connect in side USB mode. By trying, the interface type of the external device is determined, and the connection setting can be automatically made by the interface according to the interface type of the external device.
In the above description, in order to determine the type of the external device, first, after attempting to connect in one interface mode, if communication is not established, the correct interface is connected by switching to the other interface. did. As another connection method, instead of starting the connection as one interface first, first start up in a dedicated mode for determining the connected device, confirm the connected device, determine the external device, Depending on the determination result, a method of switching to the USB or HDMI mode and starting communication may be employed.
As described above, in this embodiment, the imaging apparatus can select either the manual setting mode or the automatic setting mode as the interface connection mode. For this reason, when the user already knows the interface mode of the external device, it can be easily connected to the external device by connecting after setting the predetermined interface in the manual mode.
In addition, when you do not know the interface mode of the external device, or when the external device supports multiple interface modes, you can easily connect to the external device by setting the auto mode, An imaging device that is easy to use can be provided.
Another embodiment will be described. In the previous embodiment, there is a case where the user sets the interface mode of the imaging apparatus to, for example, the USB mode and erroneously connects to the HDMI device. In such a case, a display indicating that the external device connected to the imaging apparatus is not a USB device is output to the display screen. An example of this case is shown in FIG. The user can recognize that the connection is wrong by looking at the trend message on the screen, and return to the manual setting screen again to switch the setting, thereby enabling the correct interface setting.
Next, another embodiment will be described. In the present embodiment, when the imaging apparatus and the external device can be switched to either the HDMI interface or the USB interface, the interface mode can be switched after the connector is connected.
In this case, it is assumed that the auto mode is set in advance by user setting. In this case, it is assumed that it is first operating in the USB mode. The imaging device is connected to an external device such as a personal computer. When the imaging device is connected to the personal computer, the personal computer detects that the power supply pin of the imaging device is connected and detects that an external device is connected. Next, the personal computer inquires about the device type of the external device and starts communication. This series of connection operations is performed based on the interface standard. FIG. 10 shows a screen display example of the connection state of the external device and the operation content at this time.
When communication is established in this way, it can be recognized from the recording device of the image sensor and an external personal computer. For example, the imaging apparatus operates as a device belonging to the USB mass storage class.
In the embodiment described above, the user has previously set the automatic switching mode. This is based on the premise that the user can switch the interface mode between automatic and manual on the display screen as shown in FIG. 5 as in the first embodiment. On the other hand, the imaging apparatus may not have a manual / automatic switching function, and may perform only an automatic switching operation.
A second embodiment of the present invention will be described. FIG. 11 is a block diagram illustrating a configuration of the imaging apparatus according to the present embodiment. A difference from the embodiment of FIG. 1 is that a connector for connecting to an external device is shared and a single connector 114 is used. At this time, the selection circuit 115 selects either the first interface circuit or the second interface circuit, and the connector 114 can be connected to an external device corresponding to either interface. This selection circuit is controlled by the control circuit 108. Note that the configuration shown in FIG. 11 is an example. For example, the selection circuit is deleted, the first and second interface circuits are shared, and the control circuit functions as the first and second interface circuits, respectively. You may make it control by switching so that it may. Even when the configuration shown in FIG. 11 is used, the operations other than the common use of the connector for connecting to the external device are the same as those shown in the first embodiment.

  The present invention relates to an imaging apparatus, and in particular, can be applied to an imaging apparatus, a digital camera, a digital video camera, or the like that captures a high-definition video using an imaging element for high-definition imaging and records the image on an HDD or a DVD.
