Camera based sensor for motion detection

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