Abstract

A weight-adjusted method applied in adjusting a weighting coefficient in an image scaling process. First, an absolute difference is obtained by taking an absolute value of a difference between a first pixel value and a second pixel value of an image. Next, the absolute difference is compared with several threshold values, which define several zones, so as to generate a weight-adjusted value corresponding to a zone in which the absolute difference falls. After that, a first pixel weighted value and a second pixel weighted value are adjusted according to the weight-adjusted value. Finally, a weighted pixel value is outputted by adding a product of the first pixel value and a first adjusted pixel weighted value to a product of the second pixel value and a second adjusted pixel weighted value.
