Title: METHOD AND DEVICE FOR PROCESSING HIGH DYNAMIC RANGE IMAGE
Abstract:
A method and device for processing a high dynamic range image, which is used to solve the problem of displayed image distortion that exists in the prior art. The method comprises: acquiring a high dynamic range image; separating the high dynamic range image into a first liquid crystal image and a first backlight image; compressing the first liquid crystal image by reducing the number of bits for indicating a single pixel of the first liquid crystal image, so as to obtain a compressed first liquid crystal image to be displayed by a liquid crystal layer of a display, wherein the display is used for displaying the high dynamic range image; and compressing the first backlight image by reducing the number of bits for indicating a single pixel of the first backlight image, so as to obtain a compressed first backlight image to be displayed by a backlight layer of the display.
