The display device 200 includes a communication unit 201, an input unit (input unit) 202, and a display unit (display unit) 203.

  The communication unit 201 outputs, to the display unit 203, display data input from the communication unit 101 of the connected lens apparatus 100. In addition, the operation signal input from the input unit 202 is output to the lens apparatus 100. In addition, it is also possible to transmit display device information described later to the lens device 100.

  The input unit 202 can input “upward key”, “downward key”, “leftward key”, “rightward key”, “decision key”, and the corresponding operation signals are input. Generate

  The display unit 203 displays the display data input from the communication unit 101 of the lens apparatus 100 via the communication unit 201.

  With this configuration, the display device 200 displays the display data received from the lens apparatus 100 on the display unit 203 via the communication unit 201, and the operation signal from the input unit 202 on the communication unit 201. It outputs to the lens apparatus 100.

  By connecting the communication unit 101 of the lens apparatus 100 and the communication unit 201 of the display device 200, the following processing can be performed.

Hereinafter, the process of the display data update process 1 of the lens device 100 will be described with reference to the flowchart of FIG.
This process is periodically performed according to a computer program stored in the arithmetic processing unit 102 of the lens apparatus 100. The process is started when an operation signal is received from the display device 200 via the communication unit 101, and the process proceeds to step S201.

  In step S201, the operation signal received by the arithmetic processing unit 102 is interpreted to determine which operation signal has been sent.

  In step S202, if the determination is the operation signal of "upward key", "downward key", "leftward key", "rightward key", and "decision key", the process proceeds to step S203, otherwise In the case, the process proceeds to step S205 and ends.

  In step S203, according to the determination result of the arithmetic processing unit 102, the display data configuration unit 103 configures the content of the display data based on the received operation signal. When the configuration of the display data is completed, the process proceeds to step S204.

  In step S204, the display data configured by the display data configuration unit 103 is transmitted to the display device 200 via the communication unit 101 according to a predetermined data format and a predetermined display method.

  By configuring in this manner, the operation signal from the input unit 202 is sent to the arithmetic processing unit 102, and the display data configured by the display data configuration unit 103 based on the operation signal corresponds to the operation from the input unit. It becomes possible to display on the display unit 203 as the updated setting screen.

  Next, an example of display data update processing based on an operation when the input unit 202 is operated will be described. FIG. 3 shows an example of display data configured regarding the zoom function of the lens apparatus 100. For example, the display data (FIG. 3A) configured by the display data configuration unit 103 is displayed on the display unit 203 as shown in FIG. 4A. When it is desired to move the cursor position on the first line of FIG. 4A to the second line, the “down direction key” is operated by the input unit 202 of the display device 200. The operation signal of the “downward direction key” is sent from the display device 200 to the display data configuration unit 103 of the lens device 100 via the communication units 201 and 101.

8 (a) and 8 (b) are setting screen data, FIG. 8 (c) is display data configured by the display data configuration unit 103, and FIG. 8 (d) is a setting screen displayed on the display unit 203.

For example, the setting screen data α is a setting screen data in which the zoom function is configured as shown in FIG. 8A, and the setting screen data β is a setting screen data in which a plurality of functions are configured as shown in FIG. Consider the case. If a zoom operation device (zoom demand) for operating a zoom unit (not shown) is used as the display device 200, function information related to the zoom is required. Therefore, the “request” of the display device information is to output to the lens device a request for communicating information related to the zoom function. When the lens apparatus 100 receives the display apparatus information “request” from the display apparatus 200 which is the zoom operation apparatus, the display data configuration unit 103 displays the display data related to the zoom for outputting to the display apparatus 200 (FIG. c) is configured. Therefore, the setting screen as shown in FIG. 8D can be displayed on the display unit 203.
As described above, the data can be converted into display data corresponding to the display device information.
