Patent number: 9516286Abstract: A color correction device for an image sensor is provided. The image sensor is divided into regions. The color correction device includes a quantum efficiency (QE) measurement circuit, an addressing circuit, and a correction circuit. The QE measurement circuit generates a color signal according to a sensing signal from each pixel of the image sensor. The addressing circuit receives the color signal corresponding to each pixel, obtains a location of each pixel on the image sensor, and averages all of the color signals corresponding to the pixels whose locations are disposed in one of the regions to obtain an average color signal. The correction circuit receives the average color signal to obtain a color correction matrix of the one of the regions and corrects the color signals of the pixels whose locations are in the one of the regions by the color correction matrix.Type: GrantFiled: April 4, 2014Date of Patent: December 6, 2016Assignee: VisEra Technologies Company LimitedInventors: Wu-Cheng Kuo, Yu-Kun Hsiao, Chung-Hao Lin
