Abstract
The defocused image generating methods and systems defocus an image using sets of image elements of a multi-resolution pyramid representation of the input image. Each pixel in the original image generates a region of confusion based on the image depth data for that pixel. The sets of image elements are used to represent the region of confusion using increasingly higher resolution image elements. The final defocused image is generated by compositing or combining together the sets of image elements after the region of confusion of each pixel has been decomposed into the sets of image elements.
