Light field camera is gaining its popularity since it allows users to refocus a captured image. But it is not easy to obtain a high quality all-in-focus image even though each sub-image has wide depth-of-field. Existing methods generate refocused images on every focal length, then combine them into a final all-in-focus image by selecting best focused image on every pixel position. This paper proposed a simple and fast method to generate all-in-focus image of which low light performance is very high. The resultant images are all-in-focused and have high SNR simultaneously.
