Claim:
1. An image sensor comprising: a first semiconductor substrate including a plurality of pixels two-dimensionally arranged, and a plurality of output lines to which pixel signals are output from the plurality of pixels; and a second semiconductor substrate including a plurality of signal processing units, corresponding to the plurality of output lines, respectively, which process the output pixel signals, and a plurality of output units, each shared by the plurality of the signal processing units, which output the processed signals outside of the image sensor, wherein the first semiconductor substrate and the second semiconductor substrate are stacked, N (N is a positive integer greater than 1) output lines are arranged in each column of the plurality of pixels, and the plurality of output lines and the plurality of signal processing units are connected in correspondence with each other, each of the plurality of signal processing unit includes at least two processing parts connected in series between the corresponding output line and one of the output units, and N is determined to correspond to a number of the signal processing units arranged in each column on the second semiconductor.
