Design Method of Pixel Modulation Transfer Function and Signal-to-Noise Ratio for CMOS Image Sensor
Wang Gengyun, Xie Lili, and Bu Hongbo
The modulation transfer function (MTF) value of complementary metal-oxide-semiconductor (CMOS) image sensors pixels at Nyquist frequency is typically used to evaluate the imaging quality. The MTF is mainly calculated by taking the frequency domain product of the aperture MTF and the diffusion MTF. The aperture MTF is d
