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 circuit device () includes an interface (), a parameter computation unit (), and a warp processing unit (). A rendering image and tracking information are input to the interface (). 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

A display controller may include a display update controller that may cause a color processing operation to be initiated in response to completion of an image data transmission, or a display update operation to be initiated in response to completion of the color processing operation. The display update operation may include updating display pixels of a display matrix of an electro-optic display device. A collision detector may determine whether a waveform for updating a display state of a particular display pixel has finished. The display update controller may cause the particular display pixel to be omitted from a display update operation if the waveform for updating the display state of the particular display pixel has not finished. A second display update operation may automatically be initiated when the waveform for updating the display state of the particular display pixel has finished.
