A solid-state imaging device (42) electronically images at least a portion of an image of a subject formed on a film exposure surface (14) through a photographic optical lens (12). This imaging device (42) is driven at a high speed by an imaging device driver (44) to repeatedly perform electronic imaging of the subject image. A frame memory (50) stores a subject image signal initially imaged by the imaging device (42). A two-dimensional correlating circuit (52) executes a two-dimensional correlation arithmetic operation between the subject image signal stored in the frame memory (50) 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 (14) in the x and y directions perpendicular to an optical axis of the lens (12). An actuator driver (38) drives an actuator (30) in accordance with the detected drift in the x and y directions to move the lens (12) in the x and y directions, thereby correcting the drifts. <IMAGE>
