摘    要:参照人眼的特点,作者将传统的双焦评价函数分别作用于目标图象的R、G、B分量得到三个数值,然后由这三个值计算出一个新的评价值.对一般对焦目标,这种新方法能增强传统对焦评价函数结果.本文中作者对这一方法进行了详尽的讨论.

关 键 词:对焦评价函数  对焦目标  彩色图象的R、G、B分量

Abstract:With a view to the autofocusing character of human eyes,authors analyse the RGB components of a digital focus target image separately,that is,authors apply a traditional focus measure on the R,G and B components of the target image and get three values,then authors synthesize the three values into one and use it as the new focus measure.In general,the new approach improves the effect of the traditional focus measures.In this paper,authors discuss this new method in details.
Keywords:Focus measure  Focus target  RGB components of color image
