Abstract: The amount of power and processing needed to process gesture input for a computing device can be reduced by utilizing a separate gesture sensor. The gesture sensor can have a form factor similar to that of conventional cameras to reduce costs by being able to utilize readily available low cost parts, but can have a lower resolution and adjustable virtual shutter such that fast motions can be captured and/or recognized by the device. In some devices, a subset of the pixels of the gesture sensor can be used as a motion detector, enabling the gesture sensor to run in a low power state unless there is likely gesture input to process. Further, at least some of the processing and circuitry can be included with the gesture sensor such that various functionality can be performed without accessing a central processor or system bus, thus further reducing power consumption.
