Image capturing apparatus and control method thereof

An image capturing apparatus includes a pixel portion in which a plurality of pixel blocks are arranged, each pixel block including a predetermined number of pixels; a plurality of readout circuits arranged corresponding to the plurality of pixel blocks; a supply unit that supplies drive signals to the plurality of readout circuits; a setting unit that sets image capturing conditions for each of the plurality of pixel blocks; and a control unit that carries out control so that when the setting unit has set different image capturing conditions for a first pixel block and a second pixel block, the supply unit supplies a first drive signal to the readout circuits corresponding to the first pixel block, and supplies a second drive signal to the readout circuits corresponding to the second pixel block.
