Abstract: “To measure the quality of USB camera needs a lot of time with current operations. Moreover, it might cause some mistakes because of the carelessness from tester. This research proposed an approach to reduce the test time. First, user can set the test chart of customization. Next, the proposed algorithm is applied to identify the test chart and to find the position of pattern. Finally, both the operation actions of tester and measurement time can be reduced”
