Patent ID: 7755569

Claim:
A method for adjusting visual qualities of images displayed on a monitor, wherein each image comprises m*n image pixels and the monitor comprises (m/3)*n display pixels and m and n are integers greater than or equal to 1, wherein each image pixel comprises a first color image sub-pixel, a second color image sub-pixel and a third color image sub-pixel, and each display pixel comprises a first color display sub-pixel, a second color display sub-pixel and a third color display sub-pixel, the method comprising following steps: (a) generating a grey scale value of an image pixel row according to weight values and grey scale values of a series of image pixel rows, wherein the weight value of each image pixel row of the series of image pixel rows is greater than 0; (b) respectively displaying a (1+3i) th image pixel of the image pixel row generated in step (a) on a (i+1) th display pixel of a plurality of display pixels of the monitor at a first display sub-period of a first display period, wherein i is an integer greater than or equal to 0; and (c) respectively displaying a (2+3i) th image pixel of the image pixel row generated in step (a) on the second and the third color display sub-pixels of the (i+1) th display pixel and the first color display sub-pixel of the (i+2) th display pixel of the plurality of display pixels.
