Abstract
Aspects of the disclosure are directed toward systems and methods for combining aspects of a plurality of indexed images taken at different focus distances in order to generate a final image having objects at a variety of depths remain in focus. High frequency frames associated with each of the plurality of images can be generated, each high frequency frame being representative of the high frequency content of the associated image. The high frequency content in a plurality of regions in each of the plurality of high frequency frames can be analyzed to determine which regions include valid high frequency content. A final image can be generated comprising, for each of the plurality of regions, image data from the image having like index as the high frequency frame having the greatest valid high frequency content in that region.
