Claim 0:
1. An apparatus comprising:
a photodiode configured to generate a charge in response to light within an exposure period having a first duration;
a charge sensing unit configured to accumulate at least a part of the charge within the exposure period;
a quantizer; and
a controller configured to:
determine, using the quantizer and within a 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 programmable; and
based on whether the first quantity exceeds the threshold, output 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.
