The coloring plastic product is produced with the injection molding machine. However, uneven coloring may arise. So, the method of evaluating uneven coloring quantitatively is required. The purpose of this research is developing a method of detecting and evaluating the uneven coloring of the coloring plastic using the image processing technique. In this paper, we propose a method of analyzing the uneven coloring of the coloring plastic from the variance values of luminosity, saturation and hue of light.
