    • An apparatus may include an image sensor that contains a multiplicity of pixel elements to detect one or more images and a processor circuit coupled to the image sensor. The apparatus may include a white balance module for execution on the processor circuit to receive, based upon a detected image of the one or more images, for a plurality of pixel elements of the multiplicity of pixel elements, three of more gray level values for a respective three or more color channels, to determine grayness likelihood functions for the respective three or more color channels, the three or more grayness likelihood functions comprising a proportional contribution to grey pixels of the detected image from one or more gray levels for each respective color channel, and to determine a white balance gain for two or more color channels based upon the determined grayness likelihood functions. Other embodiments are described and claimed.
    • 装置可以包括图像传感器,其包含用于检测一个或多个图像的多个像素元件和耦合到图像传感器的处理器电路。 该装置可以包括用于在处理器电路上执行的白平衡模块,用于基于对于多个像素元素的多个像素元素的一个或多个图像的检测图像来接收三个以上的灰度级值 相应的三个或更多个颜色通道,以确定相应的三个或更多个颜色通道的灰度似然函数,所述三个或更多个灰度似然函数包括对于每个相应颜色通道的来自一个或多个灰度级的所检测图像的灰度像素的比例贡献 并且基于所确定的灰度似然函数来确定两个或更多个颜色通道的白平衡增益。 描述和要求保护其他实施例。
