1. An apparatus, comprising:
time-of-flight camera system circuitry comprising a), b) and c) below:
a) an image sensor circuit;
b) a light source driver circuit;
c) configuration register space, the configuration register space to receive information pertaining to a command, the command
to cause the image sensor circuit and the light source driver circuit to generate signals that impose an offset to a distance
measurement made by the time-of-flight camera system, the distance measurement with the offset measuring a distance between
a light source of the time-of-flight camera system and an object in a field of view of the time-of-flight camera system that
is different than an actual distance between the light source and the object.
