A memory control unit 12 divides input image data into: a first block having the pixel data of a prescribed number of pixels for a plurality of lines in a line direction; a second block having the pixel data of a prescribed number of pixels for a plurality of lines, including some lines of the first block, that follow the first block in the line direction; and a third block having the pixel data of a prescribed number of pixels for a plurality of lines, including lines in the first block that are different from lines included in the second block, that follow in the line direction. The memory control unit 12 causes the divided blocks to be stored in a memory unit 13. An arithmetic processing unit 15 calculates an interpolation position that is a position before image conversion corresponding to a pixel position after image conversion. The memory control unit 12 reads the first to third blocks of pixel data, including the pixel data of pixels surrounding the interpolation position, from the memory unit 13. An interpolation processing unit 14 generates pixel data at the interpolation position through interpolation processing using the surrounding pixels that have been read out. The processing speed of image processing can be improved.
