초록
The depth of field of the photomicrograph is very narrow. But we can solve this problem by digital imaging technology. This study suggests that the way how to extend the depth of field of photomicrograph by several ways. At first, we need to take a picture of various series of focus by digital camera. And than, Input these images to computer and execute an application which have a special algorism. In this algorism, there are three steps to collect the fine focus pixel. First, read an output level of each pixel. Second, we use level information of neighbor pixel to detect which pixels have a fine focus. Last one is use saturation levels of each pixel. After these steps, we can get data of fine focus pixels. And we can reconstruct a wide depth of field image
