HALF TONE DISPLAY METHOD

摘要

PROBLEM TO BE SOLVED: To prevent deterioration in picture quality of dynamic images in the case of using the sub-field method. SOLUTION: In the half-tone display method which concurrently displays plural binary digital images that are formed by weighting half-tone dynamic images depending on the time width or the number of pulses, the portion corresponding to high-order plural bits of the half-tone represented by binary notation is displayed by continuous time-width- or pulse-number modulation using plural binary images roughly equally weighted and the portion corresponding to the remaining low-order bits is displayed by binary images weighted in compliance with binary notation.
