Abstract
A CMOS image sensor includes: a pixel array having a plurality of first pixels, a plurality of second pixels and a plurality of third pixels that are arranged in matrix form and respectively correspond to a first color, a second color and a third color. A first analog signal processing path is arranged in one side of the pixel array to process analog signals outputted from the first pixels, and a second analog signal processing path is arranged in the other side of the pixel array to process analog signals outputted from the second pixels or the third pixels. The first analog signal processing path includes a lower CDS part where one CDS circuit per two adjacent columns of the pixel array is provided. The second analog signal processing path includes an upper CDS part where one CDS circuit per two adjacent columns of the pixel array is provided.
