Abstract
Chip area is reduced using a CCD solid state image pick-up device of a frame transfer system. Permanent accumulation pixels for accumulating information charges in a first imaging operation to photograph a coarse image and a second imaging operation to photograph a fine image, and selective accumulation pixels for accumulating information charges in only the second imaging operation are arranged in an image pick-up section 11i of a solid state image pick-up device 11. The permanent accumulation pixels are disposed every, for example, three rows of the selective accumulation pixels. The number of rows of a storage section 11s is arranged to correspond with the number of rows of the permanent accumulation pixels of the image pick-up section 11i. The permanent accumulation pixel and the selective accumulation pixel have the same construction on a substrate and are distinguished by frame transfer clocks .phi.a and .phi.b to be supplied.
