Claim 0:
1. An image processing system comprising:
a light source configured to emit a nonsinusoidal light signal during a first time interval;
an image sensor comprising a plurality of pixels, the image sensor configured to:
collect incoming nonsinusoidal light signals responsive to the nonsinusoidal light signal, the incoming nonsinusoidal light signals including a first reflected nonsinusoidal light signal along a first path and a second reflected nonsinusoidal light signal along a second path; and
generate a first set of measurements of the first reflected nonsinusoidal light signal along the first path and the second reflected nonsinusoidal light signal along the second path; and

a processor configured to:
receive the first set of measurements from the image sensor;
determine a first estimated distance to an object based on the first set of measurements, and
determine, based on the first set of measurements, a corrected distance to the object using a look-up table.
