Abstract
Techniques are generally described for highlight recovery for image sensors. In some examples, a first frame of image data comprising a first pixel may be received. The first pixel may include a value Cwhere c∈(R, G, B, IR). A white balance gained value Cmay be determined using C·WB, where WBrepresents a per-color channel white balance gain. A color-corrected value Cmay be determined based at least in part on Cand a color correction matrix. An interpolation coefficient α may be determined based at least in part on a clipped representation of the color-corrected value C. A second value Cmay be determined for the first pixel by interpolating between an unclipped representation of the first pixel and an unclipped representation of Cusing α.
