1. A device comprising:
an image sensor comprising a plurality of light-sensitive pixels;
a first lens positioned over a first subset of light-sensitive pixels selected from the plurality of light-sensitive pixels; and
a controller configured to:
determine a first angle of incidence of a first light signal detected by the first subset of light-sensitive pixels;
based on the first determined angle of incidence, determine an amount of stray light incident on the image sensor; and
alter payload images captured using the image sensor based on the determined amount of stray light.
