ABSTRACT:
The invention relates to an electronic camera having self-detection function of foreign materials and a control program thereof. The electronic camera includes: an image sensor having an image pickup plane on an image plane of an optical system; a formation changing section changing a state of image formation of the optical system on the image pickup plane; and a control section driving and controlling the image sensor and formation changing section. The control section drives the formation changing section to set a plurality of states of image formation different from each other, and it drives the image sensor to obtain a plurality of images in each of the states and compares the plurality of images to find a part of the image which has not varied with a change in the state of image formation, and determines the found part as image of a foreign material.
