对于图像阵列探测器而言,由于各像元响应的不一致使得所获图像中各像元灰度存在差异(响应的非均性现象),而图像的平场校正可以非常有效地消除图像中各像元响应的不一致性.如果将图像背景或光路中影响成像的一些因素在一定程度上看作是图像探测器的响应,认为它是响应非均匀的组成部分,根据平场校正的原理对其进行处理,则可以获得较好的效果.

The Photo-Response Non-Uniformity (PRNU) is an ubiquitous matter in array image detectors because every pixel has its different from others. This difference will obviously degrade the quality of images and make it difficulty to get a clear and uniformity image. The flat field correction method for image can eliminate the serious difference among the pixels respondence very well. To some extend, many factors that can put ill effect on image may be treated as the pixel respondence to some extend. The flat field correction method ...
