Liquid crystal display (LCD) overdrive is used to remove motion blur. To effectively realize overdrive, it is necessary to efficiently compress and store previous frames. In this paper, we propose an adaptive mode selection algorithm via discrete wavelet transform (DWT) for efficient image compression while maintaining high visual quality. Moreover, we propose a mode reduction algorithm to adjust the target rate and to easily implement the H/W architecture. We simulated the performance of the proposed method at a fixed target rate and found that its performance was much better than that of conventional schemes.
