  When shooting with multiple compositions such as panoramic shooting, subject tracking shooting, fixed point shooting, etc. with multiple shooting devices, such as field racing such as horse racing and baseball, multiple shooting devices are used as appropriate for the entire venue. First, a composition determination operation is performed in accordance with the intention of creating a program.

  When performing an operation of determining and storing a shooting composition in the shooting devices arranged at the respective locations, the operator activates the setting switch 22 of the zoom operation device 21 and starts the storage operation. Since the composition information is stored as a group of data collectively by assigning a number to each piece of information, any number desired to be assigned to the composition information to be stored is assigned by operating the storage switching means 23, and the corresponding information at that time The number to be displayed is displayed on the display unit 24. Further, after determining the shooting composition using the focus operation device 20 or the zoom operation device 21, if the trigger switch 25 of the zoom operation device 21 is operated, the state quantity that is generating the shooting composition intended by the operator is obtained.

The stored state quantity is transmitted / received to / from another photographing apparatus 38 having a similar apparatus configuration via the communication means 14 of the communication processing unit 37 by turning on the communication changeover switch 16 of the main body 11. Can be performed.

  In this way, when state quantities are communicated between the image capturing apparatuses, a reference composition suitable for arranging and displaying composition information determined by each image capturing apparatus on one composition information is arbitrarily selected. It will be possible. In general, a panoramic view of the venue, which is the subject, is suitable for the reference composition, and it is only necessary to select a subject by a photographing device at a location that can photograph the entire view of the venue among the photographing devices arranged in the venue. In that case, in the photographing apparatus that is photographing the composition adopted as the full view, by turning on the reference determination switch 17 of the main body 11 that determines the reference composition of the entire subject view, as shown in FIG. The reference composition information A of the entire subject is determined.

It is possible to take a picture while grasping the composition and the whole view simultaneously.

  FIG. 4 is an explanatory diagram of an example of the entire view information and a method of combining the imaging device state quantities. As shown in FIG. 4, reference composition information A for the entire view is set on the image capturing apparatus capable of capturing the entire view of the venue among the plurality of image capturing apparatuses 1 to 4. On the determined panoramic reference composition information A, data calculation of panoramic reference data B used for area display of composition information acquired between the photographing apparatuses is performed.

  In the data calculation, the reference composition of the whole scene is determined with respect to the base point of the composition information set in each photographing apparatus and the relative range that can be photographed, based on the photographing apparatus state quantity composed of GPS data, altitude data, etc. transmitted and received between the photographing apparatuses. It is synthesized as relative arrangement information on information A. This data calculation is performed sequentially by operating the calculation trigger switch 19.

  The relative range data that can be photographed is combined with the panoramic view reference data B as indicated by Ba to Bd in FIG. 4, but on the display screen viewed by the operator, area display as indicated by Ba to Bd in FIG. Need not be done.

When output to the unit 36, the panoramic view reference data B including calculation information is transmitted to each photographing apparatus.

  In this way, when the panoramic view reference data B can be transmitted, a composition process with the composition information stored in the state quantity storage unit 35 of each photographing apparatus is performed. The received panoramic reference data B is sent to the compositing processing unit 36 in the photographing apparatus, and by operating the compositing calculation start switch 15, the composition information stored in the state quantity storage unit 35 in each photographing apparatus becomes the panoramic reference data. Synthesized into B. Since the panoramic view reference data B has relative arrangement information of the photographing range of each photographing apparatus in advance, the composition information to be combined can be arranged accurately. As a result, the composition display stored as the area displays Ca to Ce is performed on the panoramic view reference data B displayed on the second display unit 13 as shown in FIG.

  In the area displays Ca to Ce, numbers assigned at the time of composition storage can be displayed. Furthermore, even after the panoramic view reference data B is received once, the video of the panoramic reference data B can be selected to continue to be displayed via the communication means 14 as a real-time video.

  Therefore, when it is necessary to store a new composition due to an unexpected situation or the like, the composition calculation start switch 15 is activated after the new composition is stored according to the above-described procedure, so that it is added to the area displays Ca to Ce. It can also be displayed. Thereby, it becomes possible to cope with quick composition determination and display addition.

  As described above, in the imaging apparatus of the present embodiment, the main subject composition image captured by each imaging apparatus is displayed on the first display unit 12, while the composition information stored on the panoramic reference data B is displayed in the area. It is possible to display on the second display unit 13 in the form of display.
