ABSTRACT:
The invention discloses an apparatus for increasing the display gray levels. The apparatus includes a signal transformation circuit, an error diffusion circuit, and an operation circuit. According to a first predetermined manner, the signal transformation circuit transforms a set of image signals into a set of transformed signals. The error diffusion circuit receives the set of transformed signals and generates a set of diffused signals according to a judging rule. The operation circuit receives the set of diffused signals and generates a set of output image signals according to a second predetermined manner and a predetermined operational rule.
