Abstract:
1. A complementary metal-oxide semiconductor (CMOS) image sensor, comprising: a pixel array including red (R) pixels, green (G) pixels, blue (B) pixels, an effective pixel array, and a dummy pixel array configured to be shielded from light; a first analog signal processing path and configured to process analog signals output from the G pixels of the pixel array, wherein the first analog signal processing path is subdivided into a G sub-path and a G′ sub-path; and a second analog signal processing path configured to process analog signals output from both the B pixels and the R pixels of the pixel array, wherein the second analog signal processing path is subdivided into a BR sub-path and a B′R′ sub-path; wherein each of the first and second analog signal processing paths includes:
