In order to consider visual inspection utilizing peripheral vision, this paper examines the inspection times that affect defect detection. The gaze duration and the distance between defect and point of gaze are experimental factors in determining the inspection time. As the result, in case of a large sized defect, the detection rate is high regardless of the gaze duration and the distance between defect and point of gaze. In case of a small sized defect, when the gaze duration is longer and the distance between defect and point of gaze is closer, the defect detection rate is higher. Moreover, as the result of conducting multiple linear regression analysis about the experiment factors, it is obtained that judging from standardized partial regression coefficient of factors, higher defect size, less the distance between defect and point of gaze, higher gaze duration, is proved to improve defect detection.
