Abstract
An interpolated line is created between the horizontal lines of each field of an interlaced television signal on a pixel-by-pixel basis. For each pixel to be interpolated, the pixel in the same field located immediately above and below the interpolated pixel are compared. If the difference between the two values exceeds a predetermined difference, the larger or the smaller pixel value is picked for the interpolated pixel, depending upon the value of the corresponding pixel in the immediately previous field. If the difference between the two pixel values is smaller than the reference value, either of the two values or an average of the two values may be used as the interpolated pixel value.
