Abstract:	The main purpose of this research is to construct a highly efficient low cost image-calculation system. In this system the distance between the user and the targeted object can be calculated by a light signal (Super LED) received from a image input device (CCD). We are trying to accomplish two things: an image measurement in conjunction with an image depth and a fast measurement of the image`s distance. Of course, it is difficult to measure the distance between an object and an image using a simple eye lens (CCD). The hardware platform of a system is composed of a light source, a Web cam and a convex lens constitute. According to the principle of parallel optical axis, the distance can be obtained by conveying the image to the system via USB communication interface, applying a characteristic (a straight line between the light source and the object), utilizing the dimension data and using a variety of light from the light source. Consequently, the experimental results reveal that the distance between the object and the image lens can be acquired by utilizing a system where the image calculation in conjunction with a vision algorithm is used.
