Abstract: The present application discloses a method for reducing brightness of images at least partially. The method includes determining a grayscale mapping table corresponding to a previous frame of image and adjusting grayscale value of each pixel of a current frame of image based on the grayscale mapping table to enhance a contrast ratio to determine an after-adjust grayscale value of each pixel of the current frame of image. Furthermore, the method includes determining one or more coefficients of grayscale reduction based on the after-adjust grayscale value of each pixel of the current frame of image. Moreover, the method includes reducing grayscale value of each pixel of a next frame of image based on the one or more coefficients of grayscale reduction and after-adjust grayscale values of corresponding pixels of the next frame of image.
