ABSTRACT:
The present invention provides a technique of a method for driving an image displaying apparatus to suppress animated picture pseudo-contour, flicker disturbance and pseudo-contour disturbance by making weighting of light emission within a field is made equal to or almost equal to each other at all gradations. According to this technique, when an image signal of multiple gradation is expressed by dividing one field duration into a plurality of subfields with different relative ratios of luminance, a given number of subfields among a plurality of subfields are divided into “2n” subfields (SF1ato SF8b) wherein “n” represents an arbitrary integral number. Then, “2n” subfield groups (SF1ato SF8a, SF1bto SF8b) are formed so that one group divided into “2n” subfield belong to the groups different from each other. Subfield groups (A and B) are symmetrically arranged with respect to the center of one field duration, and the subfields (SFna, SFnb) divided into “2n” subfields are symmetrically arranged.
