An image signal processing apparatus for detecting a focusing state or a distance state by performing a correlation calculation of two images received by a light receiving section that includes a plurality of two dimensionally arranged photoelectric conversion elements. The apparatus includes a calculation circuit which divides a first area of the light receiving section into a plurality of blocks and calculates a focusing state or a distance state with respect to each of the plurality of blocks, a selection circuit which selects a second area included in the first area corresponding to the focusing state or the distance state of each of the blocks provided by the calculation circuit and a control circuit which divides the second area into a plurality of blocks and causes the calculation circuit to calculate a focusing state or a distance state with respect to each of the plurality of blocks.
