1. A method comprising:
detecting a saturation level of a full pixel of an optical sensor, the full pixel comprising two or more sub-pixels;
determining a sub-to-full pixel relationship between one of the two or more sub-pixels and the full pixel; and
computing an extrapolated intensity level of the full pixel based on the saturation level of the full pixel and the sub-to-full pixel relationship.
