PROBLEM TO BE SOLVED: To provide a CMOS image sensor capable of layout of CDS circuit for every 2 pixel pitch while the totally high speed operation of the element is attained even if a relatively low speed system is used. SOLUTION: In a pixel array unit, first, second and third pixels corresponding to a plurality of first, second and third colors respectively are arranged in matrix, and one CDS circuit for every two adjoining rows of the pixel array unit, and a first CDS unit for reciving an output signal of the first pixel corresponding to one of these two rows are provided. A first analog signal processing path on one side of the pixel array unit and one CDS circuit for every two adjoining rows of the pixel array unit are provided, and a second CDS unit for receiving an output signal of the second or third pixel corresponding to one row of these two rows. In addition, a second analog signal processing path at the other side of the pixel array unit is provided. COPYRIGHT: (C)2006,JPO&NCIPI
