Abstract:
1. A method for processing an image, applied to a display apparatus, wherein the image is displayed by at least one first frame f(N), and the at least one first frame f(N) is composed of a plurality of pixels, each of which respectively corresponds to an original gray level, the method comprising: calculating the amount of the original gray levels according to an original gray level difference between every adjacent two of the pixels and generating a first transfer function Fi(X) relative to the amount of the original gray levels, where i is a positive integer ranging from 1 to N; generating a Gamma curve according to the first transfer function Fi(X); and selectively adjusting the original gray levels to a plurality of adjusted gray levels according to the Gamma curve to obtain an image having enhanced contrast for display on said display apparatus; wherein the image is further displayed by a second frame f(N−1) prior to the first frame f(N), and the step of adjusting the original gray levels to the adjusted gray levels comprises:
