An image sensing apparatus which has an effective pixel portion and a light-shielded pixel portion which is arranged at an end of the effective pixel portion, comprises a detection unit which detects a column offset component for each column by performing weighted average cyclic calculation on the column at the light-shielded pixel portion; a correction unit which corrects a column offset superimposed at the effective pixel portion by performing cyclic calculation while a plurality of frames inherit the detected column offset component, and subtracting a column offset component calculated in every cyclic calculation from an output signal of the effective pixel portion; and a control unit which divides the light-shielded pixel portion into a plurality of blocks for each pixel region to be read out by one frame, and controls a block to be read out for each frame.
