Claim 12:
13. A method comprising:
energizing a lamp of a camera system, the lamp emitting light onto a subject;
acquiring image data recording the light, reflected from the subject and focused by a lenslet array comprising a plurality of lenslets arranged laterally over an image-sensor array;
resolving the image data into a plurality of component images;
transforming each of the plurality of component images onto a spatial-frequency domain;
combining the plurality of component images in spatial-frequency space to obtain a combined image of broader spatial frequency than any of the component images, including accumulating spatial-frequency content from each component image into the combined image;
inverse transforming the combined image to obtain an enhanced image having enhanced spatial resolution relative to any of the component images; and
returning the enhanced image, wherein combining the plurality of component images includes accumulating spatial-frequency content from each component image into the combined image using a phase estimate derived from the enhanced image.
