If there is a problem, the cancel button 234 is pressed (NG in step S203), and shooting is performed again. If there is no problem with the photographed image, the execution button 233 is pressed (OK in step S203). Then, a photographing attachment information request is transmitted from the digital camera 200 to the electronic blackboard device 100.
[0030]
When the electronic blackboard apparatus 100 receives the photographing attachment information request, the electronic blackboard device 100 transmits the photographing attachment information currently displayed on the LCD 101 and the bitmap data (BMP file) of the schematic diagram to the digital camera 200. Thereafter, the photograph K in the photographed photograph list is changed to photographed (step S107).
[0031]
The digital camera 200 acquires shooting auxiliary information and bitmap data from the electronic blackboard device 100, attaches them to the shot image (main image), that is, a memory card as an image file 250 in the format shown in FIG. It records in 212 (step S204). The acquired shooting accessory information is displayed on the monitor LCD 203 for a certain period of time while being superimposed on the shot image (step S205). The user can check the content of the recorded photographing accessory information on the site by looking at the display on the monitor LCD 203.

Since the digital camera 200 acquires the shooting accessory information of the shooting target from the electronic blackboard device 100 and records it in the memory card 212 in association with the shot image, the shooting target 255 is recorded. The shooting accessory information including information can be recorded in association with the shot image, and the shooting accessory information of the shooting target 255 can be easily copied to the shooting scene.
[0033]
Also, since the shooting accessory information is copied in the shooting scene, the shot image can be confirmed by playing back the captured image using a general-purpose image playback program. Therefore, there is no need for a dedicated reproduction program as in the prior art in order to confirm the shooting attachment information.
[0034]
In addition, since additional information can be manually input to the electronic blackboard device 100 as necessary, it is possible to add or change shooting attachment information on an as-needed basis.
[0035]
In the above-described embodiment, a photo list and shooting accessory information are input in advance to the electronic blackboard device 100, and the shooting accessory information being displayed on the LCD 101 of the electronic blackboard device 100 is transmitted to the digital camera 200.
