Abstract:
1. An image sensor having a plurality of pixels two-dimensionally arranged in a row direction and a column direction, comprising: a plurality of pixel amplifiers which are arranged in the column direction for each column, and one of which is shared by at least two pixels of each column; two output lines arranged for each column, to either of which signals are output from said plurality of pixel amplifiers arranged in the column direction for each column, wherein said two output lines arranged for each column alternately run to an upper side and lower side of said image sensor depending on whether the corresponding column is an odd numbered column or an even numbered column; an averaging unit which averages signals output from said two output lines arranged for the same column; a first readout circuit which is for said two output lines in the even numbered column and is arranged in the upper side or lower side of said image sensor, and a second readout circuit which is for said two output lines in the odd numbered column and is arranged in an opposite side of the first readout circuit of said two output lines in the even numbered column.
