ABSTRACT:
A solid state imaging apparatus which prevents occurrence of small aperture fading by diffraction of light and can control the amplitude level of an image signal within a prescribed range. The solid state imaging apparatus employs a solid state imaging element such as a CCD. When the level of an image signal outputted from the solid state imaging element exceeds a predetermined value, a driving motor is driven to effect adjustment of an iris. The capacitance of a variable capacitance diode provided in a voltage converting section of the solid state imaging element is controlled in accordance with the amplitude level of the image signal to control the voltage conversion efficiency of the voltage converting section of the solid state imaging element so as to fix the level of the image signal.
