摘要
本文讨论了图像运动对ＣＣＤ成像的影响及其评价标准。推导出图像在线性和正弦运动条件下的调制传递函数（ＭＴＦ）的数学表达式。分析结果表明，图像运动将引起ＭＴＦ的严重下降，造成图像模糊。
This paper describes the effect of image motion on the performance of CCD and the evaluation criterion for image quality. The mathematical expressions of MTF for linear motion and sinusoidal vibration are developed. The analytical results illustrate that the image motion gives rise to the decline of MTF and smearing of the image seriously.
