Image processing method and system

摘要

The invention provides the image method and apparatus to increase the sharpness of a resized image. The image includes a plurality of pixels with an alpha value and an image data. The method detects the alpha value of neighboring first and second pixels. Weighting values of interpolated pixels between the first and second pixels are determined. The image data of the interpolated pixels are set to be identical to the image data of the first pixel when one of the first pixel or the second pixel is zero.
