Abstract
In a frame transfer CCD image sensor the number of charge storage locations per channel (25) in the store section (35A, B) is greater than in the image section (33). Frame transfer is effected so that after each frame transfer the image charge pattern in the image section is transferred to the store section so as to leave at least one line of charge storage locations (35B) in the store section between the image section and the charge pattern transferred to the store section which contains charge resulting only from frame shift smear and is otherwise empty of charge. Electrical circuitry (41 to 57) is provided to subtract electrical signals representing charges in the line or lines containing frame shift smear charge only from electrical signals representing the image charge pattern, thereby to cancel frame shift smear in the signals representing the image charge pattern.
