Abstract: Certain aspects relate to systems and techniques for dynamically configuring frame skip for AWB calculations. For example, if RGB gains are deemed to be stable across a number of frames, the frame skip value used for AWB calculations can be increased. Changing RGB gains are indicators of image changes such as a changing scene and/or changing illuminant, which can indicate a need for updated AWB calculations, and accordingly the frame skip value can be set to zero or a low number of frames.

Abstract: Certain aspects relate to systems, methods, devices and non-transient computer readable medium for correlation based frame skipping of processing intensive image processing algorithms for image adjustments, such as automatic white balance (AWB) operations and automatic exposure correction (AEC) operations. In certain embodiments, if a scene is deemed stable based on determining a correlation between the statistics associated with a current and previous frames, certain steps for the purpose of performing processing intensive image processing algorithms, such as AWB operations and AEC operations, may be skipped.

Abstract translation: 某些方面涉及动态配置AWB计算的跳帧的系统和技术。 例如，如果在多个帧中认为RGB增益是稳定的，则可以增加用于AWB计算的帧跳过值。 改变RGB增益是诸如改变场景和/或改变光源的图像变化的指标，其可以指示需要更新的AWB计算，因此帧跳过值可以被设置为零或低数量的帧。
