PROBLEM TO BE SOLVED: To provide a device capable of properly checking whether or not data display is normal in an instrument panel.SOLUTION: A display control apparatus includes a display output control unit and a CPU. The display output control unit includes a comparison control unit 106 which performs a cyclic redundancy check related to an arbitrary region of image data. The comparison control unit includes: a region control unit 125 which selects a region of the image data on the basis of comparison region information for specifying an arbitrary region of the image displayed on a display unit as a cyclic redundancy check target region; an arithmetic processing unit 122 which performs arithmetic processing for the cyclic redundancy check related to the region selected by the region control unit; and a comparison circuit 123 which performs error detection by comparing result of the arithmetic processing by the arithmetic processing unit with its expected value. The error detection by the cyclic redundancy check is performed only on the target region of the cyclic redundancy check in the arbitrary region to facilitate the cyclic redundancy check. |
