Real time detection of defective picture sampling elements of a high resolution imager may be achieved by (1) imaging a scene by means of low resoluting power imaging optics to produce an image resolution limit spot size on the imager which is large relative to the center-to-center pitch distance of the picture sampling elements, and (2) indicating as spurious each single picture sample of the serial output from the imager that exhibits certain discriminating contrast characteristics with respect to its neighboring picture samples. This permits a spurious sample to be corrected by replacement with an interpolated value derived from its neighboring samples.
