Abstract:
A method for generating a diversified image frame formed by a plurality of image signal lines, comprising steps of:(a) determining a specific pixel frequency of one of said plurality of image signal lines; (b) adding a plurality of black pixels to the two ends of said one image signal line and outputting said one image signal line according to said specific pixel frequency, wherein when outputting said image signal line and said black pixels added beside said image signal line, a logic control technique is used for alternately switching said black pixels and said image signal line; and (c) repeating said steps (a) and (b) for outputting another one of said plurality of image signal lines until all of said plurality of image signal lines are outputted, wherein diversified pixel frequencies for said plurality of image signal lines are respectively determined in said step (a) to generate said diversified-shaped image frame, said image frame includes n image signal lines, and I3kâˆ’2, I3kâˆ’1, and I3k are adjacent pixels on the kth one of said image signal lines, wherein said step (a) includes steps of: (a1) calculating the total pixel number of (I3kâˆ’2+I3kâˆ’1+I3k); and (a2) calculating and outputting said specific pixel frequency, wherein said specific pixel frequency is said total pixel number of (I3kâˆ’2+I3kâˆ’1+I3k) divided by a duty cycle of a horizontal image-synchronous-signal of said kth image signal line, wherein n and k are positive integers and 1&lE;k&lE;n.
