Original Abstract Submitted
A circuit device includes an overlay processing circuit and an error detection circuit. The overlay processing circuit performs overlay processing of first input image data on a first area of second input image data and outputs a result of the overlay processing as output image data. The error detection circuit calculates a first error code value corresponding to image data of the first area of the output image data and a second error code value corresponding to image data of a second area not overlapping the first area of the output image data. The error detection circuit performs error detection on the output image data by comparing the first error code value with a first expected value and comparing the second error code value with a second expected value.
