In the manufacturing industry, it is common to conduct visual inspection in order to ensure the quality of products external appearance. Visual inspection is one of the sensory evaluations by means of human sensation. Since there is dispersion in the result of the inspection according to the suitability and the experience of the worker, the standardization of the work is a problem to be solved. Therefore , in order to quantify the work of visual inspection, in this paper, the effect of the difference of the defect color on detection rate is examined. Specifically, an experiment was done with luminance and hue of the defect as variation factors. As a result, the detection rate of defects with same hue increases with the increase in the luminance difference of background and defect. Moreover, the detection rate of defects with same luminance increases with the increase in yellow-blue component of the background and defect
