Data compressor
专利汇可以提供Data compressor专利检索，专利查询，专利分析的服务。并且PURPOSE:To simply and exactly execute the processing at high speed by controlling the code quantity in accordance with a difference of data in the bands in the horizontal and the vertical directions of a block to be encoded. CONSTITUTION:In inputted image data, in-frame prediction data, and inter-frame prediction data are inputted to a code predictor 1 directly, and through a motion compensation and difference data generator 6, respectively. The predictor 1 executes separately plural processings in the vertical direction and the horizontal direction with respect to the inputted data, controls the code quantity in accordance with a difference of the respective data, and outputs them to a horizontal pre-filter 2a, a vertical pre-filter 2b and a quantizer 4. According to such constitution, in accordance with a result of prediction, a band limit value is adjusted independently in the vertical. direction and the horizontal direction, and also, a quantization step is determined, therefore, even in the case of image data whose frequency characteristic is different greatly in the horizontal direction and the vertical direction, the processing can be executed appropriately. simply and at high speed.，下面是Data compressor专利的具体信息内容。
