Abstract. A structure of an experimental stand for studying parameters of serial digital video cameras based on matrix CMOS photodetectors is proposed. Requirements for the characteristics of the test bench elements in determining the uneven sensitivity of the photodetector section and evaluating the signal-to-noise ratio when changing the irradiation level and exposure time are justified.
Keywords: video camera, CMOS photodetector, parameter error, characteristics of test bench, gain, exposure time
