Patent ID: 8248501

Claim:
An image sensor for electronic cameras, having a plurality of light-sensitive pixels ( 2 ) arranged in rows and columns, wherein the light-sensitive pixels ( 2 ) of a respective column are divided into a first pixel group ( 21 ) and a second pixel group ( 22 ) according to a permanent division pattern, and wherein, in each column, the light-sensitive pixels ( 2 ) of a respective first pixel group ( 21 ) are coupled to a common first column amplifier ( 41 ) via a common first column line ( 51 ) and the light-sensitive pixels of a respective second pixel group ( 22 ) are coupled to a common second column amplifier ( 42 ) via a common second column line ( 52 ), characterized in that the number of the light-sensitive pixels ( 2 ) in the first pixel group ( 21 ) and the number of light-sensitive pixels in the second pixel group ( 22 ) are different for different columns, wherein the permanent division pattern of the light-sensitive pixels ( 2 ) into the first pixel group ( 21 ) and the second pixel group ( 22 ) alternates quasi-randomly between the columns or between groups of adjacent columns.
