Claim Text:
1. An imaging apparatus comprising: pixel regions which include an aperture pixel region, a first light-shielded pixel region provided on a first side of the aperture pixel region, and a second light-shielded pixel region provided on a second side of the aperture pixel region and corresponding to each row in the aperture pixel region, wherein the second side is different from the first side; a reading unit configured to read a signal from the pixel regions for each row; a selection unit configured to select a reading row of the pixel regions; a correction unit configured to correct for each row a black level of an image signal read from the aperture pixel region using a black level reference signal read from the second light-shielded pixel region of a current read row and a black level reference signal read from the first light-shielded pixel region or the second light-shielded area pixel region of a read row that is before the current read row; and a control unit configured to control the correction unit to correct the black level of the image signal read from the aperture pixel region using the black level reference signals based on a step amount of a signal level occurring in the signal read from the pixel regions of the non-sequentially read row in a case where a read row of the pixel regions is non-sequentially selected by the selection unit.
