摘要:
A two dimensional video convolver (10) generates visually acceptable images on a standard television receiver and includes a first adder stage (12, 14), a second adder stage (16, 18, 20), and two pixel time period delays (22, 24). The first adder stage simultaneously receives binary data from three adjacent pixels in a predetermined line in a first direction of a picture to be reproduced on a display during each pixel scan period. The binary data of each of three pixels is processed with a predetermined weight to generate a binary first stage output signal representative of a weighted sum of the plurality of the three pixels in the predetermined line. The second adder stage is responsive to the binary first adder stage output signal during a time period for each of three predetermined adjacent lines in a second orthogonal direction of a picture to be reproduced on a display. The second adder stage processes the binary weighted sum of each of the three lines with a predetermined weight to generate a video convolver output signal representative of a weighted sum of the three pixels in a first direction over three adjacent lines in a second orthogonal direction. Weighting is accomplished in the first and second adder stages by using binary data bits for a pixel as received when the weight for that pixel is a numerical one, and by shifting the received binary data bits by a predetermined number of y bits in a first direction to provide a multiply function when a respective weight is greater than one and equals 2
