In an image processing device having an image processing unit, a first determination process determines whether each of the plurality of blocks is a single-color block, a non-single-color block, or a non-determinative block. Determination of the non-determinative block is made when neither a single block condition nor a non-single-block condition is met. A second determination process determines whether the non-determinative block is the single block or the non-single block based on a result of the first determination process with respect to a neighboring block neighboring the non-determinative block. The blank determination process determines whether the image is a blank image based on at least one of number of single color blocks determined in the first determination process or the second determination process and number of non-single-color blocks determined in the first determination process or the second determination process. |
