ABSTRACT:
A video display monitor employs interpolation which maintains sharpness in images which have large differences in signal levels of picture elements and assuring smoothness of images such as lamps which have small differences in signal levels. The difference in the signal level differences of respective adjacent picture elements is detected by delay and subtraction. A decoder produces a signal for interpolation based on the input of an interpolation coefficient and the absolute value of the interpolation coefficient which is output from an absolute value detector.
