Image capturing apparatus capable of performing readout from a plurality of divided areas of a pixel area and control method therefor

摘要: In an image capturing apparatus that comprises a pixel area of pixels arranged in matrix, output circuits apply preset processing to signals read out parallel from divided areas obtained by dividing the column direction and processed signals, controller performs control execute first driving for reading corresponding predetermined voltage circuits, second area, correction circuit generates gain data based on correcting differences between different columns each areas, corrects using generated areas.
