PROBLEM TO BE SOLVED: To prevent the processing for blank page determination and image color determination from becoming inefficient.SOLUTION: When a determination is made that a read image G is a non-blank image, from the number of blocks determined to be a non-single color block, it is not required for a block that is a selected block to perform non-single color block determination processing, subsequently. When a determination is made that a read image G is a non-blank image, from the number of blocks determined to be a non-single color block, a scanner 1 does not perform non-single color block determination processing but performs chromatic color block determination processing of the selected block. |
