Abstract
Abstract A solid state image sensing system includes a CCD (10) and a vibration table (12). The vibration table (12) swing-drives the CCD (10) in response to a drive signal (28) generated by a drive pulse generator (26), in such a mannerthatthe CCD (10) is vibrated in a horizontal direction (16) in one vibration cycle consisting of two succeeding frame periods each having A and B fields.
