A circuit deviceincludes a light source driving value output unitand a pixel value output unit. The light source driving value output unitobtains a corrected intensity image Lled by correcting an intensity image Lint of an input image RGBin in a target display zone based on the light intensity distribution of a light source corresponding to the target display zone, and obtains a light source driving value Ldrv based on the largest corrected intensity value in the corrected intensity image Lled. The pixel value output unitcorrects pixel values of the input image RGBin based on the light source driving value Ldrv, and outputs the corrected pixel values as pixel values of an output image RGBout.

Display system, electronic apparatus, mobile body, and display method

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.

A circuit device includes an image processing circuit and a comparison circuit. The image processing circuit performs a first mapping process and a first rotation process on an input image to generate an image for a head up display. The image processing circuit performs, on an image, a second mapping process that is a reverse mapping process of the first mapping process and a second rotation process that is a reverse rotation process of the first rotation process to generate an image. The comparison circuit performs a comparison between the image and the image and outputs a result of the comparison as information for detecting an error in the image.
