ABSTRACT:
A solid-state imaging apparatus capable of changing a vertical resolution (MTF) without damaging the dynamic resolution. A CCD drive circuit 6 for driving a CCD image sensor 2 of an imaging section 3 is controlled by a control section 7 to independently vary effective charge storage periods of respective photoelectric conversion of the CCD image sensor 2 with respect to photoelectric conversion of odd columns and photoelectric conversion elements of even columns and to add and mix, every field, image pick-up charges obtained by respective adjacent photoelectric conversion elements of odd and even columns to read them out. A CCD drive circuit 6 for driving a CCD image sensor 2 of an imaging section 3 may also be controlled by a control section 7 to carry out control of the electronic shutter function of the CCD image sensor 2, and to control the effective charge storage periods of respective photoelectric conversion elements in a manner caused to interlock with the electronic shutter function.
