Claim 14:
15. A camera system comprising:
a series of lamps configured to emit light;
a lamp driver configured to energize the series of lamps;
an image-sensor array configured to acquire image data; and
a lenslet array comprising a plurality of lenslets arranged laterally over the image-sensor array and configured to focus the light, reflected from a subject, onto the image-sensor array;
wherein the image-sensor array provides the image data to an image engine configured to:
receive the image data from the image-sensor array,
resolve the image data into a plurality of component images,
transform each of the plurality of component images onto a spatial-frequency domain,
combine the plurality of component images in spatial-frequency space to obtain a combined image of broader spatial frequency than any of the component images, wherein combining the plurality of component images includes accumulating spatial-frequency content from each component image into the combined image using a phase estimate,
inverse transform the combined image to obtain an enhanced image of enhanced spatial resolution relative to any of the component images, and
return the enhanced image, the phase estimate being derived from the enhanced image.
