ABSTRACT:
A semiconductor CCD focal plane array convolver is taught which permits performing convolution functions on the focal plane array chip. An X-Y array of photosensitive pixels is disposed in a semiconductive substrate, with a CCD roadway comprising a pattern of rows and columns of conductive gates upon the substrate surrounding and defining the X-Y array of pixels. The number of gates for each pixel are selected to permit charge from the pixel to be collected in either a first charge holding packet for a positive convolution coefficient, or in a second paired charge holding packet for a negative convolution coefficient. The convolution function is performed by applying gate signals which move the charge packets around the CCD roadway. A differencing electrometer is provided at the periphery of the CCD roadway to permit differencing the accumulated charge stored in the paired charge holding packets to difference the positive and negative convolution coefficients to provide a convolution output signal.
