Title
(EN) Compensation table compression method
(ZH) 补偿表压缩方法
Abstract
(EN)
The present invention provides a compensation table compression method by which the quality loss of the original compensation table is not detected by the human eye and the compression efficiency is greatly increased. Compared with the prior compensation table compression algorithm, the compensation table compression method of the present invention can obtain the best quantization step size without iteration, reduce the occupation of memory space, save the hardware resources of the system, reduce the cost and the time consumed for transmitting and burning data.

(ZH)
本发明提供一种补偿表压缩方法。该补偿表压缩方法通过视觉无损压缩补偿表,使人眼察觉不出原始补偿表的质量损失,且极大增加压缩效率,和现有的补偿表压缩算法相比,本发明无需迭代即可获得最佳量化步长,减少对内存空间的占用,节省系统的硬件资源,且可以降低成本及减少传输和烧录数据耗费的时间。
