Abstract

A single, focused image can be composited by selecting the best-focused match in the stack for each image region (Clarke, 1985. Mallat, 1999). The optimal choice of parameters, including focus and aperture, for the images in a focal stack are well established (Ding, et. al., 2007). Capturing a focal stack with a large-scale high-resolution camera was implemented. Multiplex a focal stack into a single sensor image in a similar fashion as colour arrays multiplex different color channels into a RAW camera image. However, to the knowledge of the author, this camera has not yet been built. Split the aperture of a camera using circular mirrors and multiplex the result into different regions of a single photograph.
