  Next, an overall operation at the time of shooting of the digital camera 10 according to the present embodiment will be briefly described.

  First, the CCD 24 performs imaging through the optical unit 22 and sequentially outputs analog signals for R (red), G (green), and B (blue) indicating the subject image to the analog signal processing unit 26. The analog signal processing unit 26 performs analog signal processing such as correlated double sampling processing on the analog signal input from the CCD 24 and sequentially outputs the analog signal to the ADC 28.

  The ADC 28 converts the R, G, and B analog signals input from the analog signal processing unit 26 into 12-bit R, G, and B signals (digital image data) and sequentially outputs them to the digital signal processing unit 30. To do. The digital signal processing unit 30 accumulates digital image data sequentially input from the ADC 28 in a built-in line buffer and temporarily stores the digital image data directly in a predetermined area of the memory 48.

  Digital image data stored in a predetermined area of the memory 48 is read out by the digital signal processing unit 30 under the control of the CPU 40, and a white balance is adjusted by applying a digital gain according to a predetermined physical quantity. Processing and sharpness processing are performed to generate digital image data of predetermined bits, for example, 8 bits.

  The digital signal processing unit 30 performs YC signal processing on the generated digital image data of predetermined bits to generate a luminance signal Y and chroma signals Cr and Cb (hereinafter referred to as “YC signal”), and a YC signal. Are stored in an area different from the predetermined area of the memory 48.

  The LCD 38 is configured to display a moving image (through image) obtained by continuous imaging by the CCD 24 and can be used as a finder. When the LCD 38 is used as a finder, the LCD 38 is generated. The YC signals thus output are sequentially output to the LCD 38 via the LCD interface 36. As a result, a through image is displayed on the LCD 38.

  Here, when the release button 56A is half-pressed by the user, after the AE function is activated and the exposure state is set as described above, the AF function is activated and focus control is performed, and then the fully-pressed state is continued. In this case, the YC signal stored in the memory 48 at this time is compressed in a predetermined compression format (in this embodiment, JPEG format) by the compression / decompression processing circuit 54 and then passed through the external memory interface 50. To the memory card 52.

  Next, an outline of software operations in the digital cameras 70 and 72 will be described with reference to FIG. FIG. 4 shows software blocks of each digital camera when the digital cameras 70 and 72 are applied as the photographing system shown in FIG. The digital cameras 70 and 72 are equipped with key drivers 80a and 80b, applications 82a and 82b, and API (Application Program Interface) 84a and 84b, respectively. In addition, libraries and functions not shown are also installed.

  The key drivers 80a and 80b include a physical key driver such as a release button and a touch panel driver. Accordingly, the key drivers 80a and 80b also detect that the operator is pressed.

  The applications 82a and 82b are applications for operating the digital camera. APIs 84a and 84b are APIs used by the applications 82a and 82b.

  In the present embodiment, for example, when a release button is pressed by the digital camera 72, the key driver 80a detects the pressing and notifies the application 82a of the detection. In the case of normal processing that is not set for remote operation, the API 84a mounted on the digital camera 72 is used as indicated by the dotted line. However, when the remote operation setting is set, the digital operation is performed via a wireless LAN. The camera 70 is notified that the release button has been pressed. The application 82b of the digital camera 70 executes processing when the release button is pressed using the API 84, as in the case of notification from the key driver 80b, and the return value from the API 84b is digitally transmitted via the wireless LAN. The camera 72 is notified.

  In this way, remote operation by the digital camera 72 is possible. Also, the application 82a of the digital camera 72 can send a message to the digital camera 70 via the wireless LAN instead of calling the API 84a, and can acquire the return value of the API 84b from the digital camera 70 in the same manner as when the API 84a is called. Conventionally used software can be used.

  Similarly, the application 82b of the digital camera 70 is notified of the same detection contents notified from the key driver 80b via the wireless LAN, and transmits the return value of the API 84b to the digital camera 72 via the wireless LAN. Therefore, it is possible to use software that has been used conventionally.

  Next, operation state information used between the digital cameras 70 and 72 will be described with reference to FIG. The operation state information indicating the operation state includes a FUNCTION and a VALUE as shown in FIG.

  FUNCTION indicates a function, and VALUE indicates a value used in the function. For example, the function when FUNCTION is 01h (h indicates a hexadecimal number) is MODE (operation mode), and when VALUE at that time is 02h, the operation mode is PLAY (playback). Yes.

  Such operation state information can be used as it is if it is the same model, and in the case of different models, it is previously unified between different models. It is desirable that this operation state information covers all operation states.

  With the above-described operation state information, the operation state of the digital camera 72 can be notified to the digital camera 70, and the digital camera 70 can be controlled based on the operation state.

  The protocol used in the communication between the digital cameras 70 and 72 described above may be UDP that is light in processing when transmitting digital image data, and may be reliable TCP in the case of other operation state information, for example. Further, digital image data may be transmitted by broadcast or multicast instead of unicast.

  Hereinafter, processing in the digital cameras 70 and 72 will be described with reference to flowcharts. In the following description, a remotely operated digital camera such as the digital camera 70 is expressed as a slave, and a remotely operated digital camera such as the digital camera 72 is expressed as a master.

  First, slave processing will be described with reference to FIG. In step 101, a digital image data transmission thread for transmitting digital image data indicating a subject to the master is activated. This thread corresponds to digital image data transmission means, and details of this processing will be described later.

  Step 102 is waiting for the above-described operation state information. When the operating state information is received, in step 103, the slave controls the operation of the digital camera based on the operating state information. Thereafter, in step 104, the slave transmits an ACK message indicating that the operating state information has been received to the master. Note that the above-described digital image data indicating a subject is digital image data indicating a through image in the present embodiment.

  Next, the processing of the digital image data transmission thread will be described with reference to FIG. In step 201, the slave acquires data for one page of the through image. In step 202, the slave transmits the acquired data as digital image data.

  Thereafter, the slave sets a timer in step 203. This timer is a timer for measuring an interval for transmitting a through image. If a timeout occurs at step 204, the process of step 201 is executed again.

  The digital image data transmission thread described above is a thread that is generated or deleted as necessary.

  Next, a master process corresponding to the slave process will be described with reference to FIG. In step 301, the master activates a digital image data reception thread. Details of the processing of this digital image data reception thread will be described later.

  Next, in step 302, the master executes master basic processing. This master basic process will be described with reference to the flowchart of FIG.

  Step 401 is waiting for a user operation. When an operation is performed by the user, in step 402, the master creates operation state information based on the operation content. In the next step 403 (operation state information transmission means), the master transmits the created operation state information to the slave. Thereafter, in step 404, the master sets a timer. This timer is an ACK message wait timer, and is a timer for confirming whether or not the slave has received.

  In step 405, the message branches. If the timeout message is received from the thread managing the timer, the master transmits the operation state information again in step 403. On the other hand, when an ACK message is received from the slave, the process ends.

  Next, the processing of the digital image data reception thread (see FIG. 8: S301) will be described with reference to FIG. Step 501 waits for digital image data reception from the slave. In step 502, the master determines whether or not there is manipulator information indicating a manipulator to be displayed on the subject image indicated by the digital image data. There are two types of operators based on operator information provided in advance in the master and those based on operator information received from the slave.

  When the master and the slave are of the same model, the control information is the same for the master and the slave, so the control is displayed based on the control information that the master has in advance. As a result, a user accustomed to the operation of the slave can perform a remote operation with exactly the same operation.

  On the other hand, when the master and slave are different models, the master acquires the operating element information from the slave, so that a user who is accustomed to the operation of the slave can perform remote operation with exactly the same operation.

  Return to the description of the flowchart. In the determination process in step S502, when there is operation information indicating an operation element to be displayed in an overlapping manner, the master displays the operation element in an overlapped manner on the subject image in the designated display area in step 503. Here, the designated display area is an area that is set to display the subject images from a plurality of slaves so that the subject images do not overlap.

  If there is no operation element to be displayed in a superimposed manner, the master displays the subject image in the designated display area in step 504.

  Next, in the above-described processing of the slave and the master, processing for receiving operation information from the slave and displaying the operation information on the subject image will be described. First, the structure of the operator information will be described with reference to FIG. As shown in FIG. 11, the operator information includes an X coordinate, a Y coordinate, a button radius, and a button name.

  The X coordinate and the Y coordinate are position information on which the operation element is displayed on the LCD. The button radius is shape information indicating the radius of the operation element expressed as a button. The button name is name information for identifying the button.

  The master receives and displays from the slave the number of operation elements that display the above-described operation element information.

  Processing of the slave that transmits the operation element information will be described with reference to FIG. In step 601 (operation element information transmitting means), the slave transmits operation element information. In step 602, a digital image data transmission thread for transmitting digital image data indicating a subject to the master is activated.

  Step 603 is waiting for reception of operating state information. When the operating state information is received, in step 604, the slave controls the digital camera based on the operating state information. Thereafter, the slave transmits an ACK message to the master in step 605.

  Next, a master process corresponding to the slave process will be described with reference to FIG. Step 701 is waiting for operation information reception. When the control information is received, the master stores the control information in step 702. When the operator information is saved, it is determined that the operator information is present in the digital image data reception thread process (see FIG. 10) described above, and the operator is displayed.

  In step 703, the master activates a digital image data reception thread, and in step 704, master basic processing (see FIG. 9) is executed.

  FIG. 14 shows a screen displayed on the master LCD 38 by the above processing. FIG. 14 shows a subject image 90 and a plurality of operating elements 92. As shown in FIG. 14, the operator is displayed so as to be superimposed on the subject image. The user's contact with the operation element is detected by the touch panel.

  Next, a process in which the master displays a list of subject images indicated by digital image data received from a plurality of slaves and causes the user to select a slave that transmits operation state information from the list of subject images will be described with reference to FIG. explain.

  Since this process only needs to be handled by the master, only the process of the master will be described. In step 801 (list display means), digital image data reception threads are activated for the number of subject images to be displayed. This process is a process of activating six digital image data reception threads when, for example, subject images received from six slaves are displayed on the LCD 38 as shown in FIG. By this processing, it is possible to display a list of subject images indicated by digital image data received from a plurality of slaves.

  Step 802 is waiting for selection of a subject image by the user. When the user touches the subject image, the CPU 40 can specify the subject image selected by the user from the position information detected by the touch panel (selecting means). When the subject image is selected, in step 803 (imaging device specifying means), the master specifies the digital camera that transmits the operation state information based on the selected subject image. As this specifying method, for example, there is a method of associating the displayed subject image with the IP address of the slave that transmitted the subject image. In step 804, the master executes master basic processing (see FIG. 9) for the identified slave.
