PROBLEM TO BE SOLVED: To perform high-speed processing by reducing memory access.SOLUTION: An image processing device comprises: a first storage section which stores image data indicating color information by a pixel unit; a second storage section which stores block image data indicating color information by a block unit including a plurality of adjacent pixels; a third storage section which stores block state information indicating validity or invalidity of each block included in the block image data; and a drawing section which draws image data on the basis of a source image to make the first storage section store the image data, draws block image data on the basis of the source image to make the second storage section store the block image data and generates block state information on the basis of the source image to make the third storage section store the block state information. |
