Apparatus and method for accessing image data in reduced transfer cycles. The image data access apparatus has: a plurality of external memories in which a plurality of parallel pixel data that are adjacent to each other in a prescribed block area of the image data are separately stored at assigned addresses; a determination circuit for outputting, based on the coordinate of at least one pixel data out of a plurality of parallel data, a memory selection signal for selecting an access route to an external memory storing the one pixel data, the coordinate obtained by raster scanning; and a memory selector for selecting access routes to the plurality of external memories based on the received memory selection signal, and accessing the plurality of parallel pixel data in the same cycle. This can realize accessing the pixel data in the external memories in reduced transfer cycles.
