Abstract
An adaptive pseudo halftone generator which achieves high resolution and faithful rendering of gray scales or gradations even when video image data comprise a mixture of alphanumeric characters and other symbols represented by two-level signals and photographs and like images represented by multi-level signals. A value indicative of a degree of continuity of tones of an input video signal is computed to control the threshold value adapted for dot pattern representation on the basis of the computed value.
