Abstract
An optical navigation method includes: providing an optical sensor to operate in a run mode to sense pixel images to perform a displacement calculation; performing a low feature detection upon the sensed pixel images; and, controlling the optical sensor switching from the run mode into a rest mode in which the optical sensor does not perform the displacement calculation when the low feature detection indicates a low feature condition result.
