Abstract: Techniques are described for luminance-adaptive processing of hexa-deca red-green-blue-white (RGBW) color filter arrays (CFAs) in digital imaging systems. Original image data is acquired by a sensor array configured according to a hexa-deca RGBW CFA pattern, and associated ambient luminance information is also acquired. The ambient luminance information is used to detect one of a number of predetermined luminance conditions. Based on the detected luminance condition, embodiments can determine whether and how much to downsample the original image data as part of the readout from the sensor array (e.g., using binning techniques), and whether and how much to remosaic and/or upsample the downsampled data to generate an RGB output array for communication to other processing components of the imaging system.
