The question of information coding real time compression in quantization process was studied.
研究量化过程的信息编码实时压缩问题。
Image codec process easily causes blur in the decoded image because of that the quantization accuracy is not high enough and part of the high frequencies is lost.
在图像信息的编码过程中，由于量化精度不高造成高频成分的损失导致图像不清晰。
The analysis result and process are valuable for the decision of quantization bit number in the system design.
分析过程和结论，对于系统设计时量化比特数确定具有参考意义。
