Staggered high-dynamic-range image capture with luminance-driven upsampling of pixel-binned image sensor array output

Techniques are described for efficient staggered high-dynamic-range (HDR) output of an image captured using a high-pixel-count image sensor based on pixel binning followed by luminance-guided upsampling. For example, an image sensor array is configured according to a red-green-blue-luminance (RGBL) CFA pattern, such that at least 50-percent of the imaging pixels of the array are luminance (L) pixels. In each image capture time window, multiple (e.g., three) luminance-enhanced (LE) component images are generated. Each LE component image is generated by exposing the image sensor to incident illumination for a respective amount of time, using pixel binning during readout to generate appreciably downsampled color and luminance capture frames, generating an upsampled luminance guide frame from the luminance capture frame, and using the upsampled luminance guide frame to guide upsampling (e.g., and remosaicking) of the color capture frame. The resulting LE components images can be digitally combined to generate an HDR output image.
