Дослідження шумових характеристик матричних фотоелектричних перетворювачів

Abstract

The noise characteristics of the CCD and CMOS matrices are experimentally investigated. The study was carried out for two cameras: the Olympus sp-600uz and the Xiaomi Redmi x3 smartphone. Dark frames were made in the most approximate conditions. Histograms of noise are asymmetric. The noise distribution law good agree with Poisson's law. The noise of the matrices is distributed unevenly across the frame. A greater noise falls on the edges of the frame. The revealed regularities can be used in the development of new noise suppression algorithms in photo and video equipment.
