Abstract: A practical software of processing digital images of electron probe was developed in windows 95 environment. Functions of the software include change colors, synthesis of images, magnification by insert data, display in three dimensions, histogram, segment of gray scales, reverse of gray scales, shift of gray scales, mapping of gray scales, smoothing, sharpening and so on. With those processing techniques, it is easy to enhance any information interested on a digital image of electron probe. The image synthesized is a new way to represent minerals.
