System on a chip camera system employing complementary color filter

摘要

A system on a chip (SoC) camera system includes a pixel array which has a color filter and converts an optically photographed image to an electrical analog image signal, an analog signal processing unit for adjusting the electrical analog image signal outputted from the pixel array to a predetermined level to thereby output a digital image signal, and a digital signal processing unit for performing white color compensation and color revision to make the digital image signal close to an original image, wherein the digital signal processing unit is integrated with the pixel array and the analog signal processing unit in one chip. The SoC camera system employs a complementary color filter adopting a progressive scanning scheme of reading all pixels at one time and outputting color signals to thereby obtain an image having improved resolution and color sensitivity.
