Abstract
In certain embodiments, an input device includes a housing, a processor disposed in the housing, and an image sensor to track a movement of the input device with respect to an underlying surface. The image sensor includes a pixel array and operates in two modes of operation including a first mode of operation where the processor causes the image sensor to utilize a first plurality of pixels in the pixel array when tracking the movement of the input device or a second mode of operation where the processor causes the image sensor to utilize a second plurality of pixels in the pixel array when tracking the movement of the input device, where the second plurality of pixels has fewer pixels than the first plurality of pixels.
