Abstract

A commonly used approach to extract depth information is by measuring the quality of focus in the image plan. When applying this approach to obtain a full field depth map from one image only a sparse set of data can be obtained. That is depth information can not be obtained using information from just a single pixel. The information must be extracted from a group of pixels (e. g. using sharpness or size of objects in the image). This sparse data limitation can be eliminated by combining depth from focus with chromatic aberration. This concept color encoded depth will be discussed with examples of various possible configurations. Color encoded depth can be used for image enhancement for either human interpretation or computer processing. The strengths and limitations of the approach will be enumerated and potential applications presented.
