Abstract
A method of performing a lens effect to determine a realistic pixel content of a realistic pixel transformed by a virtual lens from a plurality of image pixels is disclosed. First, an offset mask having an offset value corresponding to a pixel point in the virtual lens is provided, and a plurality of weight masks respectively corresponding to the image pixels are also provided, each of the weight masks having a weight value corresponding to the pixel point. Then, a reference pixel position is calculated by adding a realistic pixel position to the offset value, and one of the image pixels with a position equal to the reference pixel position is selected as a reference pixel. Finally, a weighted process is performed on the addition of an adjacent pixel content and a reference pixel content according to the weight value in a first weight mask of the weight masks, thereby the realistic pixel content of the realistic pixel is acquired.
