Claim 0:
1. A method for generating an in-focus image of a scene on a pixel-array sensor, comprising:
receiving a defocused image of the scene by the pixel-array sensor;
storing, in a memory of the pixel-array sensor, the defocused image as plurality of threshold pixel values;
detecting interference fringes from the scene at a plurality of scan depths by a pixel-array in the pixel-array sensor to generate a plurality of detected pixel-values;
processing, with circuitry on the pixel-array sensor, the plurality of detected pixel-values with the plurality of threshold pixel values to generate a thresholded signal for each pixel; and
outputting the in-focus image according to the thresholded signals.
