Patent ID: 8045031

Claim:
An image sensor for electronic cameras, comprising a plurality of light sensitive pixels (P) arranged in rows ( . . . , Z m-1 , Z m ) and columns (S 1-1 , . . . , S 1-4 , S 2-1 , . . . , S 2-4 , . . . ); a number of output amplifiers (V 1 , V 2 , V 3 , V 4 ); a switching device ( 11 , 13 ), for selectively switching the pixels (P) of one of the rows ( . . . , Z m-1 , Z m ) to the number of output amplifiers (V 1 , V 2 , . . . , V 4 ); and a control device ( 17 ) for controlling the switching device ( 11 , 13 ), characterized in that the image sensor is made such that an order in which the plurality of light sensitive pixels (P) are switched to the output amplifiers (V 1 , V 2 , V 3 , V 4 ) is varied with respect to the order in which the plurality of light sensitive pixels (P) are arranged along a row ( . . . , Z m-1 , Z m ) of the image sensor; wherein the columns (S 1-1 , . . . , S 1-4 , S 2-1 , . . . , S 2-4 , . . . ) are divided into a plurality of column groups (S 1 , S 2 , . . . ); and in that the number of the output amplifiers (V 1 , V 2 , V 3 , V 4 ) corresponds to the number of the columns (S 1-1 , . . . , S 1-4 , S 2-1 , . . . , S 2-4 , . . . ) of a column group (S 1 , S 2 , . . . ), with the number of columns (S 1-1 , . . . , S 1-4 , S 2-1 , . . . , S 2-4 , . . . ) of each column group (S 1 , S 2 , . . . ) being associated with the number of output amplifiers (V 1 , V 2 , V 3 , V 4 ) in accordance with an association order, and with mutually different association orders being provided for at least some of the plurality of column groups (S 1 , S 2 , . . . ).
