Fig. 1

Illustrates three different gain patterns, with two different gain settings (ISO), for a sensor with a Bayer pattern CFA, and (middle) how the multiple gain pixels are filtered to reconstruct the HDR output value z _j at pixel location X _j . The different gains, g ₁ and g ₂, corresponding to, e.g., 1× and 16×, amplification of the analog readout enables the capture of a wider range of intensities and extends the dynamic range in the final image
