Patent ID: 8154637

Claim:
An image sensor for electronic cameras having a plurality of light-sensitive pixels (P) which are arranged in rows and columns and whose signals are conducted via a plurality of column lines (S k−2 , S k−1 , S k , S k+1 , S k+2 ) to column amplifiers (V k−2 , V k−1 , V k , V k+1 , V k+2 ), wherein a column amplifier (V k−2 , V k−1 , V k , V k+1 , V k+2 ) is associated with each column line (S k−2 , S k−1 , S k , S k+1 , S k+2 ), characterized in that at least one further column amplifier (V k−1 , V k+1 ) is associated with the respective column line (S k ) and is also associated only with at predetermined number of adjacent column lines (S k−2 , S k−1 ; S k+1 , S k+2 ), said predetermined number being less than the total number of column lines, with a switching device ( 11 , 13 , 15 , 17 , 19 ) being provided to selectively switch the respective column line (S k ) to one of the associated column amplifiers (V k−1 , V k , V k+1 ) and with a control device ( 23 ) being provided for the control of the switching device ( 11 , 13 , 15 , 17 , 19 ), wherein column lines (S k−1 , S k , S k+1 ) with which the same column amplifier (V k ) is associated from a respective association column group (ZSG k ), with a plurality of association column groups (ZSG k−1 , ZSG k , ZSG k+1 ) being provided and with at least some of the association column groups (ZSG k−1 , ZSG k , ZSG k+1 ) mutually overlapping.
