An IR LED production yield estimation method for IP-camera
Po-Hsiung Lin, Fan‐Chieh Cheng, Shih-Chia Huang · 2015
IR LEDs are widely employed in the Internet protocol cameras to increase the imaging effects on the very dark scenes. Hence, the production yield of IR LEDs significantly affects the performance of displaying effects for IP cameras. In this paper, we propose a very efficient way to estimate the IR LED production yield based on image processing technique. Experimental results show that our method effectively improves the working efficiency of the operators on the production line.
