An image capturing apparatus comprises a pixel area having a plurality of pixels arranged in a matrix; output circuits that apply preset processing to signals read out in parallel from divided areas obtained by dividing the pixel area in a column direction and output the processed signals in parallel; a controller that performs control to execute first driving for reading out signals for obtaining correction data from the divided areas to the output circuits, and second driving for reading out image signals from the divided areas to the output circuits; and a correction circuit that obtains the correction data from the signals read out through the first driving and corrects the image signals using the correction data. The controller executes the first driving with respect to pixels in a part of rows that includes a row at a border of the divided areas.
