ABSTRACT:
In a self-luminous display, one field of a video signal is divided into a plurality of sub-fields. A plurality of tables stores a plurality of converting pixel data, each of the converting pixel data is different from other converting pixel data in weight in accordance with a luminance level applied thereto. The difference between a pixel data of a selected central pixel in a picture and pixel data of pixels adjacent to the central pixel is detected, and a first select signal when there is a difference, and a second select signal when there is no difference are produced. In response to the first and second select signals, one of the converting pixel data is selected in accordance with distinction of the select signal. A corresponding pixel is driven for a period dependent on the selected converting pixel data.
