DIGITAL CAMERA

1 . A digital camera, comprising:

an imaging module;

a first wireless communication module that is used to perform radio communication with a monitor device separated from a camera body; and

a volume of data transferred per unit time being reduced compared to a volume of moving-image data transferred via wired communication to display the moving-image, when moving-image data obtained by said imaging module being transferred to said monitor device via said first wireless communication module.

2 . The digital camera as in claim 1 , wherein said camera body includes said imaging module, a first connector half and said first wireless communication module;

said monitor device includes a monitor, a second connector half connectable to said first connector half and a second wireless communication module capable of being communicable with said first wireless communication module; and said monitor device being attachable to and detachable from said camera body; and

the volume of data transferred per unit time is reduced compared to the volume of moving-image data transferred to said monitor device by said wired communication through said first and second connector halves being coupled together, when the moving-image data are transferred to said monitor device via said first and second wireless communication modules.

3 . The digital camera as in claim 1 , wherein whether to use said wired communication or said radio communication for transferring the moving-image data is determined by detecting a connection between said first and second connector halves.

4 . The digital camera as in claim 1 , wherein the reduction of the volume of data transferred per unit time comprises a reduction in the resolution of the moving image data that will be transferred.

5 . The digital camera as in claim 1 , wherein the reduction of the volume of data transferred per unit time comprises a reduction in the frame rate of the moving image data that will be transferred.

6 . The digital camera as in claim 1 , wherein the reduction of the volume of data transferred per unit time comprises an increase in the compression rate of the moving image data that will be transferred.

7 . A digital camera, comprising:

a camera body that includes an imaging module, a first wireless communication module, a detector and a controller; and

a monitor device that is detachable from said camera body and that includes a monitor and a second wireless communication module complemental to said first wireless communication module;

said detector determines whether said monitor device is attached to or detached from said camera body and said controller changes a volume of data transferred per unit time in accordance with the determination of said detector.

8 . The digital camera as in claim 7 , wherein said controller reduces the volume of data transferred per unit time when said detector determines that said monitor device is detached from said camera body.
