Abstract
An image processing apparatus including: a first acquisition unit configured to acquire write coordinates corresponding to a position of a pixel up to which writing is completed; a second acquisition unit configured to acquire readout coordinates corresponding to a position of a second block where readout is to be performed of a plurality of second blocks included in the image data written in the memory; and a controller configured to control whether or not to permit a readout request from a reading unit based on a positional relationship between the write coordinates acquired by the first acquisition unit and the readout coordinates acquired by the second acquisition unit, wherein the controller performs control so as not to permit the readout request from the reading unit if the positional relationship between the write coordinates and the readout coordinates does not satisfy a predetermined condition.
