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.

Circuit device, electronic apparatus, and mobile body

A display system () includes a rendering image generation unit (), a parameter computation unit (), and a warp processing unit (). The parameter computation unit () computes a latency compensation parameter for compensating a latency including a rendering processing latency of a rendering image based on tracking information. The warp processing unit () performs latency compensation processing for compensating the position of a virtual object in a display region based on the latency compensation parameter.

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

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.

Circuit device, electronic device, and vehicle

Provided is a circuit device that can appropriately detect an error in a display image in a head up display, an electronic apparatus, an error detection method, and the like. The circuit device includes an image processing circuit and a comparison circuit. The image processing circuit performs first mapping processing, which maps an input first image on a second image to be projected onto a projection target object, and second mapping processing, which converts the second image to a third image. The second mapping processing is reverse mapping processing of the first mapping processing. The comparison circuit performs comparison between the first image and the third image, and outputs the result of comparison as information for performing error detection on the second image.

Circuit device and electronic apparatus

A circuit device () includes a coordinate transform circuit () and a mapping processing circuit (). The coordinate transform circuit () performs coordinate transformation from an input coordinate (IXY) to an output coordinate (QXY). The mapping processing circuit () generates a second image (IMG) to be displayed in a display panel for displaying an image in a curved screen display by performing mapping processing on a first image (IMG) that is input based on the output coordinate (QXY). The coordinate transform circuit () performs the coordinate transformation from the input coordinate (IXY) to the output coordinate (QXY) by performing computation processing using a second or more order polynomial representing the coordinate transformation.
