PROBLEM TO BE SOLVED: To provide a solid-state imaging apparatus that can obtain a reference signal level to adjust characteristics of signal processing circuits from an imaging element to a video signal processing circuit. SOLUTION: The solid-state imaging apparatus where a reference light source being a white light source to adjust the lightness of the light source is placed between the CCD imaging element and a lens forming an optical image onto the CCD imaging element, is provided with a summing integration means that applies summing integration of optical electric charge signals obtained from the reference light source to the CCD imaging element so as to store the signals for generating a white reference signal level in order to solve the problem. |
