Abstract
The algorithm for synthetic image generation with the lens effect consists of two consecutive processors: the hidden-surface processor and the focus processor (Potmesil and Chakravarty 1981). This algorithm was revised by Chen (1987) using simple light particle theory instead of the wave theory to avoid the complicated calculation and the huge memory consumption. However, from the experimental observation, the algorithm based on hidden-surface processor and focus processor can only serve as an approximation formula for the slightly defocused scenes. The purpose of this paper is to present a new algorithm for the highly defocused scenes. An image generated using this new algorithm was compared to the real photograph captured by a camera, and no noticeable difference of the defocused effect between the image and the photograph can be detected.
