Claim:
1. An interchangeable lens digital camera comprising an interchangeable lens, a camera body, to which the interchangeable lens is detachably attachable, and communication units which are electrically connected by attaching the interchangeable lens to the camera body, enabling communication between the interchangeable lens and the camera body, wherein, A) the interchangeable lens comprises: a shake detection sensor that detects the direction and amount of a shake of the interchangeable lens; a shake compensation device that moves a shake compensation lens located in the light path so as to compensate for the shake on the basis of the direction and amount of the shake; and a lens controller that transmits deviation information based on the direction and amount of the shake to the camera body through the communication unit; B) the camera body comprises: an image sensor having a plurality of pixels arranged in a matrix to image a subject and output an image signal; an image data processor that produces a live view image from the image signal, for displaying the live view image on an image display unit; and a body controller for controlling the camera body; C) the communication unit comprises: a serial communication unit for serial communication of information between the lens controller and the body controller; and a condition communication unit for communication of condition informing signals, which represent conditions of the interchangeable lens and the camera body, between the lens controller and the body controller, wherein the lens controller and body controller transmit and receive the deviation information through one of the serial communication unit and the condition communication unit, wherein the body controller controls the image data processor to selectively execute a first process and a second process, wherein the first process is cropping an image signal for one scanning line after another from a predetermined cropping range, the scanning line being a row of the pixels in the matrix, and the second process is determining a corrected cropping range on the basis of the deviation information and cropping an image signal for one scanning line after another from the corrected cropping range, and wherein the lens controller transmits mode information indicating whether the shake compensation device is active or inactive to the body controller through the serial communication unit, and the body controller controls the image data processor to execute the first process when the shake compensation device is active, or controls the image data processor to execute the second process when the shake compensation device is inactive.
