Zusammenfassung:In this paper, we present a novel automatic anti-vignetting method which effectively alleviates color shading artifacts regardless of ambient color temperature. The proposed method incorporates both a Color Temperature Metric (CTM) and a Vignetting Gain Control (VGC) algorithm in a commercial Image Signal Processor (ISP) which is embedded in mobile phone camera modules. Experimental results validate that our proposed method explicitly addresses the color shading problem in a wide variety of color temperatures.
