Single bit plane based block truncation coding for color image compression in LCD overdrive

This paper presents an improved block truncation coding (BTC) for color image compression in LCD overdrive. To improve the BTC, single bit plane is used to represent the R, G and B bit planes and correct the two representative levels. Simulation results show that the proposed algorithm can significantly improve the compression ratio of the BTC from 4:1 to 6:1 with the limited performance losing about 0.297dB. Compared with other competitive improved BTC such as VQ-BTC, the proposed algorithm also performs 2.107dB better.
