Classification: CPC G | IPC G

Claim 6:
7. A method for calibrating an image processing system, comprising:
emitting light from a light source;
receiving reflected emitted light at a sensor array having a plurality of pixels wherein receiving reflected emitted light comprises receiving emitted light reflected off an exterior obstruction, wherein the exterior obstruction covers the light source and the sensor array;
determining an obstruction distance between the exterior obstruction and the light source;
collecting and storing incoming signals at the plurality of pixels in a corresponding plurality of storage units;
storing collected signals comprising emitted light reflected off the exterior obstruction in a corresponding subset of the plurality of storage units;
determining a depth measurement for at least a subset of the plurality of pixels from the collected signals stored in the corresponding subset of the plurality of storage units; and
calibrating the image processing system using the depth measurement and the obstruction distance.
