IMAGE DISPLAY APPARATUS

摘要

An image display apparatus, such as a plasma display panel, suppresses dynamic false contours with gradation levels sufficiently retained. The image display apparatus has agitation constant adder for generating a plurality of agitation constants for a gradation level corresponding to an image signal, for selecting one agitation constant therefrom, and for adding the agitation constant to the image signal. As a result, dynamic false contours can not be visually perceived because their portions are dispersed by superimposing an agitation to each image signal.
