Abstract
An optical system comprising, in order from the object side, a rotating mirror which functions to deflect an optical axis for rays coming from an object point and scan fractions of an image, an aperture stop, an imaging lens system and electronic image pickup sensors. The optical system is configured to allow pickup of a high resolution image by using CCD's having a small number of picture elements.
