A circuit deviceincludes an error detection circuitand a processing circuit. The error detection circuitobtains a glare index value, which is an index value indicating glare of a head-up display, based on image data IMD for head-up display. The error detection circuitdetermines whether or not a glare index value has exceeded a first threshold value, and when the glare index value exceeds the first threshold value, detects occurrence of a first glare error. When occurrence of a first glare error is detected, the processing circuitperforms processing corresponding to the first glare error.
