A display driver includes first interface circuitry, a graphic memory, image processing circuitry, and drive circuitry. The first interface circuitry is configured to receive an edge illumination command from a controller external to the display driver. The graphic memory is configured to store image data. The image processing circuitry is configured to render an edge-illuminated image by overlaying an edge illumination graphic on a first image corresponding to the image data in response to the edge illumination command. The edge illumination graphic extends along an edge of a display region of a display panel. The drive circuitry is configured to drive the display panel based on the edge-illuminated image.

Example devices may include a display (such as an emissive display), and a controller, where the controller is configured to determine an image content parameter for a displayed image shown on the display, and adjust a duty ratio of the display based on the image content parameter. The duty ratio may be dynamically adjusted based on, for example, an image content parameter that may be related to the brightness of the image, or a portion thereof. The controller may be configured to determine an image content parameter for each of one or more portions of a displayed image, and adjust a duty ratio for corresponding parts of the display based on the image content parameter associated with the respective one or more portions of the displayed image.

The disclosure provides a method, device, and readable storage medium for adjusting image quality. The display device system selects a focus area of a target image, and outputs a mapping relationship curve of an input luminance value and an output luminance value of the target image. Then, an input luminance value range of pixels in the focus area of the target image is calculated, and upper and lower edge coefficients of the input luminance value range are proportionally adjusted to obtain new upper and lower edge coefficients. The mapping relationship curve is adjusted according to the new upper and lower edge coefficients, thereby adjusting the focus area of the target image.

A camera includes an image sensor, a signal processor, and an output unit. The image sensor obtains a first image being a subject image including an eye of a user of a head-up display. The signal processor generates a second image by reducing a resolution of an area of the first image other than an eyebox area. The eyebox area is an area within which a virtual image displayable by the head-up display is viewable by the eye of the user. The output unit outputs the second image to the head-up display.
