Claim 22:
23. A method, comprising:
setting an exposure period to have a first duration;
setting a measurement period to have a second duration, the measurement period being set separately from the exposure period;
enabling a photodiode to generate a charge in response to light within the exposure period having the first duration;
accumulating, at a charge sensing unit, at least a part of the charge within the exposure period;
determining, using a quantizer and within the measurement period having a second duration, whether a first quantity of the at least a part of the charge accumulated at the charge sensing unit exceeds a threshold, and a time it takes for the first quantity to exceed the threshold, wherein the first duration and the second duration are individually programmed; and
based on whether the first quantity exceeds the threshold, outputting a first value representing the time or a second value representing a second quantity of the charge generated by the photodiode within the exposure period to represent an intensity of the light.
