ABSTRACT:
A drive apparatus for a self light-emitting display unit accomplishes pseudo intermediate tone display and pseudo outline compensation while maintaining a high image quality. In executing dithering-based pseudo intermediate tone display and pseudo outline compensation data conversion on pixel data corresponding to the individual pixels of the self light-emitting display unit, dither coefficients to be added to the individual pieces of pixel data are changed field by field in this dithering process. Furthermore, the pseudo outline compensation data conversion performed is associated with each dither coefficient added in the dithering process.
