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.

Circuit device and head-up display apparatus

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.

Provided is a circuit device for detecting error on a display image obtained by image processing. The circuit device includes an image acquisition circuit configured to acquire image data, an image processing circuit configured to perform image processing on the image data to obtain a display image, and an index acquisition circuit configured to obtain an index for performing error detection on the display image. The index represents a degree of matching between a foreground image, which is an image of a given region of the display image, and a reference image, which is a reference with respect to the foreground image. The index is obtained based on pixel values of the display image and pixel values of the reference image or based on pixel values of an edge image of the display image and pixel values of an edge image of the reference image.
