摘要： PURPOSE: An error diffusion method for reducing low gray scale false contour noise of a display device is provided, which reduces false contour noise generated in a low gray scale area of a display image, and improves a brightness repeatability. CONSTITUTION: According to the error diffusion method, a difference between lightness as to a gray scale before gamma correction and lightness as to a gray scale after gamma correction of an input image signal is calculated as a display error, and the display error is weighted and is diffused to a peripheral pixel of a display pixel. An analog image signal inputted from the external is converted into digital data having n bit gray level(ST701,ST702). Display error weighted with an error diffusion coefficient is added to the above digital data and is output as the first input gray(ST703). And the first input gray executes an image display according to the second input gray having gamma correction(ST704).
