Abstract:
1. A semiconductor integrated circuit comprising: a data conversion device having an input for receiving arbitrary first image data units of N bits each representing a corresponding one of a plurality of first color tones for a corresponding pixel, wherein N is a natural number not smaller than three, said data conversion device being effective for converting said first image data units, based on a predefined conversion algorithm, into corresponding second image data units each consisting of a first sub-unit of K bits, a second sub-unit of L bits, and a third sub-unit of M bits, wherein K, L and M are natural numbers and the sum of K, L, and M is greater than N; a data storage device that successively stores said second image data units obtained for a plurality of pixels; and a signal generation device that successively generates and outputs, for a plurality of pixels, first through third signals respectively representing the data stored within said first through third sub-units of a corresponding second image data unit; where said data conversion device includes a decoder circuit for associating each of said first color tones represented by a corresponding one of said first image data units to one of a plurality of predefined second color tones, the association made by said decoder being determined by said predefined conversion algorithm; and wherein said decoder circuit is implemented as one of a register circuit or a bank of flip-flop circuits.
