Abstract:
A system and method for selectively setting an optical navigation resolution utilizes a comparison of a comparison displacement value to a threshold value to set the optical navigation resolution to an effective resolution selected from a plurality of effective resolutions. The comparison displacement value is based on at least one of a first displacement value in a first direction and a second displacement value in a second direction, which were derived for estimating motion.
