Abstract

A circuit device includes an image processing circuit, a CRC calculation circuit, and a determination circuit. Processing target image data obtained by adding known image data to effective image data is input to the image processing circuit, and the image processing circuit executes image processing on the processing target image data. The image processing circuit outputs processed effective image data which is the effective image data subjected to the image processing and processed known image data which is the known image data subjected to the image processing. The CRC calculation circuit obtains a CRC value based on the processed known image data. The determination circuit determines correctness of the image processing by comparing the CRC value with a CRC expected value of the processed known image data.
