Abstract:
1. A de-warping processing method for digital images, used for outputting a first image at a first image window according to a partial region of a second image in a second image window, the de-warping processing method comprising: segmenting the first image window into a plurality of first blocks; segmenting the second image window into a plurality of second blocks according to an amount of the first blocks and locations of the first blocks; calculating a coordinate transformation parameter by a group of first vertex coordinate values of one of the first blocks and a group of second vertex coordinate values of corresponding one of the second blocks; transforming coordinate values of the first block into estimated coordinate values of the corresponding second block according to the coordinate transformation parameter; obtaining a pixel content value from the second image window according to each of the estimated coordinate values, and writing the pixel content value into a pixel with the corresponding coordinate value in the first block; and processing all the first blocks for outputting the first image.
