ABSTRACT:
A solid-state imaging device electronically images at least a portion of an image of a subject formed on a film exposure surface through a potographic optical lens. This imaging device is driven at a high speed by an imaging device driver to repeatedly perform electronic imaging of the subject image. A frame memory stores a subject image signal initially imaged by the imaging device. A two-dimensional correlating circuit executes a two-dimensional correlation arithmetic operation between the subject image signal stored in the frame memory and subject image signals sequentially imaged during a film exposure period for the subject image, thereby calculating drift between the subject images formed on the film exposure surface in the x and y directions perpendicular to an optical axis of the lens. An actuator driver drives an actuator in accordance with the detected drift in the x and y directions to move lens in the x and y directions, thereby correcting the drifts.
