ABSTRACT:
Pixels of a digital image are produced by an area image sensor which includes a sparse array of elements. Each element is multiply exposed by different pixels of a light image. The light image is scanned in such a pattern between element exposures so that each digital image pixel has a nearest-neighbor digital image pixel that was produced by a different sensor element. By means of this arrangement, a high quality image can be produced from the digital image even if a sensor becomes defective (drops out).
