<p>Methods, devices and computer readable media for implementing a "selective gray world" approach for color balancing are described. The disclosed techniques involve the use of noise-optimized selection criteria and, more specifically, in some embodiments, the interpolation between corresponding values in noise-optimized weighting tables when calculating white balance gains. Estimated scene lux levels may provide a valuable indicator of expected scene noise levels. The image processing techniques described herein may be executed by an image capture device or a general purpose processor (e.g., personal computer) executing a user level software application. The described color balancing techniques may be implemented by dedicated or general purpose hardware, general application software, or a combination of software and hardware in a computer system. :x =L itJ Ej5 LUJ L~j 6" (-AJ f-4 L" LU 0'J UN -- J '-cc oc</p> |
