从维基网上摘录的介绍：

CombineZM (CZM) is an open source image processing software package for creating extended depth of field images. It runs on Windows XP and 2000. CombineZM is based on CombineZ5, a program which runs on older versions of Windows and is no longer maintained.

CombineZM is designed to blend the focused areas of several partially focused digital photographs in order to create a composite image with an extended depth of field (DOF), created from the in-focus areas of each image.
