  • Circuit device and head-up display apparatus
    Patent number: 12230175
    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.
