摘　　要：影响静止图像压缩的因素有很多方面,各方面的影响也各不相同。文章介绍了图像压缩的基本知识和量化步长对图像压缩的影响,并通过仿真实验给出了不同量化步长情况下的压缩图像。There are many factors which would affect still image compression, and their impacts are different. This article describes the basics of image compression and the impact of Quantization Step Size on image compression, and we give some compressed images affected by different Quantization Step Sizes through simulation experiments.
