ABSTRACT:
An image pickup device using a solid-state image sensor adapted to provide an optical component having a multiple curved surface, polyhedral surface, symmetric cylindrical surface, axially symmetric aspherical surface or asymmetric refracting surface in an objective lens system, or lengthen a shape of an image formed on an exit end face of an illuminating optical system in a direction parallel to a scanning direction of the solid-state image sensor, or select an angle made by a line segment connecting between the centers of individual exit end faces of two illuminating optical systems with the scanning direction of the solid-state image sensor to .+-.40.degree. or less, or extend a shape of an aperture of a stop in a direction parallel to the scanning direction of the solid-state image sensor, in order to make it possible to fabricate the device in a small size and at a low cost and eliminate moire and false color without reducing resolving power.
