ABSTRACT:
A method and apparatus for generating a pseudogaussian characteristic in the display of video information presented in digital form from a read-write memory that is continuously updated as the scan input requires, and read out one line at a time, preferably with conventional TV fields of odd and even interlaced lines. Picture elements (pixels) of each line L read for display are summed with a predetermined fraction of the sum of the values of corresponding pixels of adjacent lines L-1 and L+1, thus forming a vertical pseudogaussian calculation for the pixels of line L. Horizontal pseudogaussian calculation of the pixels is then performed in a similar manner using two pixel delay elements connected in cascade and connected to an adder to presum values of pixels P-1 and and P+1 as an input to a second adder which sums the output of the first adder, divided by a predetermined value, with the value of pixel P.
