An electronic device has pixels that form an active area of a display for displaying images for a user. A layer of black ink or other opaque material may be formed on an inner surface of a display cover layer in an inactive area of the display that does not overlap pixels. The housing may have sidewalls such as a rear housing wall that faces away from the display. Ambient light sensor windows may be formed from tapered holes or other holes. The tapered holes may be formed in the opaque material on the display cover layer, may be formed in a rear housing wall or other hosing structure, or may be formed in other portions of the electronic device. Non-tapered holes may also form windows. Tapered holes may have sidewalls with portions that run parallel to their longitudinal axes and portions that are angled relative to their longitudinal axes.

The present invention relates to a display device and a control method therefor, and involves the concept of controlling a display to reduce luminance from a default luminance to a first luminance for a first reduction time when brightness of a fixed area is maintained for a first predetermined time or more, and controlling the display to increase the luminance from the first luminance to the default luminance, when a set-top box receives, from an external device within a second predetermined time, a first signal for changing a screen from a first screen to a second screen.

Disclosed are a multi-region backlight control system, a multi-region backlight control method, a television and a readable storage medium. The multi-region backlight control system includes a color liquid crystal display screen, a non-color liquid crystal display screen, a first driver, a second driver, a constant backlight source, and a main controller; the color liquid crystal display screen and the non-color liquid crystal display screen are sequentially fixed on the constant backlight source, and the non-color liquid crystal display screen is disposed between the color liquid crystal display screen and the constant backlight source; the main controller is respectively connected with the first driver, the second driver and the constant backlight source, the first driver is electrically connected with the color liquid crystal display screen, and the second driver is electrically connected with the non-color liquid crystal display screen.

The technology provides an interior camera sensing system for self-driving vehicles. The sensor system includes image sensors and infrared illuminators to see the vehicle's cabin and storage areas in all ambient lighting conditions. The system can monitor the vehicle for safety purposes, to detect the cleanliness of the cabin and storage areas, as well as to detect whether packages or other objects have been inadvertently left in the vehicle. The cameras are arranged to focus on selected regions in the vehicle cabin and the system carries out certain actions in response to information evaluated for those regions. The interior space is divided into multiple zones assigned different coverage priorities. Regardless of elude size or configuration, certain actions are performed according to various ride checklists and the imagery detected by the interior cameras. The checklists include pre-ride, mid-ride, and post-ride checklists.

An electronic apparatus includes a memory storing instructions and a processor configured to execute the instructions to identify a display environment of an image, correct characteristics of a test image provided to identify a user's visual perception for characteristics of the image to correspond to the identified display environment, display the test image having the corrected characteristics on a display, and correct the characteristics of the image based on the user's adjustment input for the characteristics of the displayed test image.

A method for digital image enhancement on a display of an electronic device includes receiving, by the electronic device, an original image, sensing, by the electronic device, an ambient light, generating, by the electronic device, a virtual content appearance of the original image based on the ambient light and characteristics of the display of the electronic device, determining, by the electronic device, a compensating color tone for the original image based on the virtual content appearance, modifying, by the electronic device, the original image based on the compensating color tone for the original image, and displaying, by the electronic device, the modified original image for a current viewing condition.

A display device is provided. The display device includes a display configured to display at least one of an image and a text; a sensing unit configured to sense ambient illuminance; and a processor configured to gradually increase an output luminance value of the display, if a specific condition is satisfied based on the ambient illuminance sensed by the sensing unit and display attributes.
