Abstract
A device such as an optical mouse includes a light source for illuminating an imaging surface, thereby generating reflected images. The device also includes an optical motion sensor for generating one-dimensional projection data based on the reflected images, filtering the projection data, and generating movement data based on the filtered projection data. The movement data is indicative of relative motion between the imaging surface and the device.
