Filed: 2002-05-31
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the contour of a moving picture is not sufficiently suppressed and a large number of fields are required for the display in the conventional halftone display method using the division of the subfield. SOLUTION: The subfield with small weight is weighted as 1, 2, and 4..., the subfield with large weight is weighted so that the weight is increased with a nearly fixed difference, the subfield with the large weight is not made to turn on as far as possible, but is encoded, and when the subfield with the large weight is compelled to turn on, light-emission of the adjacent subfield with next large weight is suppressed and encoded. Thereby, the contour of the moving picture is reduced with a small number of the subfields.
