1. A method comprising:
detecting an intensity level of a full pixel from a plurality of pixels of an optical sensor, one or more full pixels of the plurality of pixels comprising at least two sub-pixels;
detecting an intensity level of one or more sub-pixels;
detecting that the intensity level of the full pixel of the optical sensor has reached a saturation level of the full pixel; and
in response to detecting that the intensity level of the full pixel of the optical sensor has reached the saturation level of the full pixel, computing an extrapolated intensity level of the full pixel based on the intensity level of the one or more sub-pixels.
