Abstract
An optical pointing device includes a variable frame rate controller to reduce power consumption. Frame rate can be varied through analog devices by varying the reference current, or through digital devices by varying the length of time between successive frames. The variable frame rate controller can accept input from various measurements such as velocity of the device, or a spatial frequency of the surface on which the device is situated.
