Abstract: The present disclosure relates to a display device, including an LCD screen, wherein the LCD screen includes a backlight source provided with a plurality of zones; each zone is provided with visible light sources; and at least one zone is provided with infrared light sources; wherein the infrared light sources are configured to emit infrared light having different bands, and the infrared light of the different bands, after irradiating an object, is collected by a multispectral infrared camera and used for three-dimensional reconstruction of the object based on a photometric stereo method.

Abstract: The present disclosure relates to a display device, an image processing method and device, an electronic device, and a storage medium. The method includes: identifying a viewpoint area on a LCD screen of a user, where a backlight source of the LCD screen is arranged with infrared light sources in at least one zone; calling a combination of cameras corresponding to the viewpoint area to acquire images, where the combination of camera includes a color camera and/or a multispectral infrared camera, and the acquired images include at least one frame of color image acquired by each camera; calling a respective method according to the number of directions of the infrared light sources to reconstruct a normal vector, so as to perform a three-dimensional reconstruction of an object according to the normal vector. This solution can achieve a high-precision three-dimensional reconstruction of an object.
