This paper proposes a new method of color-gray image transformation. In comparison with gray image processing, color image processing is not often applied to appearance inspections because of its high cost and complexity of processing. To solve this problem, we have developed a method for rapidly transforming a color image into a gray-scale image by the use of a look-up table without losing useful information for inspection. In this method the gray level is decided by the distance between representative points of clusters. To extract an object clearly, all background clusters are transformed to an equal level and the borders of objects and backgrounds are enhanced.<br>The experimental results indicated detecting edges to a level of subpixel precision in the transformed images. This method is presented to show its validity for appearance inspections.
