Abstract: A circuit device 100 includes an error detection circuit 110 and a processing circuit 120. The error detection circuit 110 obtains 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 circuit 110 determines 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 circuit 120 performs processing corresponding to the first glare error.

Abstract: A circuit device is used for a head-up display apparatus. The circuit device includes a distortion correction circuit and an error detection circuit. The distortion correction circuit performs a distortion correction on input image data as image data of an input image and outputs output image data as image data of an output image after the distortion correction. Respective first divisional areas of a first divisional area group formed by division of the input image correspond to respective second divisional areas of a second divisional area group in the output image in the distortion correction. Here, the error detection circuit detects an occlusion error in a display image of the head-up display apparatus based on the output image data of the respective second divisional areas.
