Abstract:
1. An image processing method applied in an image processor for processing an image, the image comprising a plurality of first pixels each having a pixel value, a first reference pixel value representing a mean value of the pixel values of the first pixels, the pixel values of the first pixels being distributed within a first distribution range, the image processing method comprising: selecting a plurality of second pixels from the first pixels, wherein the pixel values of the second pixels are distributed within a second distribution range smaller than the first distribution range of the first pixels; obtaining a local characteristic of the image according to the second pixels; and adjusting a parameter of the image according to the local characteristic; wherein the first distribution range is bounded between a second reference pixel value and a third reference pixel value, and the second distribution range is bounded between the second reference pixel value and a fourth reference pixel value other than the third reference pixel value; and wherein the fourth reference pixel value equals to a mean value of the first reference pixel value and the second reference pixel value.
