Abstract
In digital imaging, we can not avoid noise which inserted in image. But it can be reduced by using several methods. There are many way to reduce noise but there are also have many problems to adapt these methods to DSLR cameras. Noise can be reduced by some kinds of special software. It working but it reduces details in the image also. So, we can not make high quality images by this way. In this lecture, we experimented about stacking method which can reduce the noises in image but can keep or increase details in the image. We use Canon EOS 10D camera and take several pictures of the ISO15739 noise measuring target and try to find numbers of the image which can make high signal to noise ratio.
