Claim 6:
7. A pixel-array sensor for generating an in-focus image of a scene, comprising:
an array of pixels for receiving interference fringes generated from recombining a reference beam and an optical beam reflected by objects in the scene, said interference fringes comprising an initial defocused image and a signal comprising a plurality of detected pixel-values;
a memory for storing a plurality of threshold pixel values of the defocused image; and
circuitry for receiving the plurality of detected pixel-values and corresponding threshold pixel value from the memory, generating a thresholded signal for each pixel and outputting the in-focus image according to the thresholded signals.
