Abstract
A digital camera whose lens is detachable, comprising a judging section for judging whether an image failure is caused due to dirt adhering on an image sensor device unit including image sensor device, an illuminating member which is disposed in the vicinity of the image sensor device unit such that irradiation light can enter the image sensor device and which is driven when at least the judgment is made, a memory for storing a position of a picture element of the image sensor device corresponding to image sensor data causing image failure when the judging section judged that image failure has been caused, and a correcting section for correcting the image sensor data output from the image sensor device unit based on picture element position data stored in the memory when a picture is photographed after the lens is interchanged.
