Research on Testing Technology of CMOS Camera Module

Abstract:

After the completion of the CMOS(Complementary Metal-Oxide-Semiconductor Transistor) camera module assembly,in order to test the image quality of module. In this paper, based on the ISO12233 standard chart proposing a CMOS camera module modulation transfer function MTF (modulation transfer function) of test method, MTF average value calculated for each module with high contrast and grayscale method, and validation processing to detect unqualified imaging module. The results show that MTF detection method used in this paper can quickly and accurately detect the quality camera module, and stable and reliable, playing an important role to found the quality problems and improve the efficiency of production.
