Abstract
An optical navigation method includes: detecting inertia of an image of a feature point; and determining an effective sensing region of an image sensing array according to the detected inertia for reducing power consumption. Besides, an optical navigation apparatus includes a detecting circuit and a determining unit. The detecting circuit is arranged for detecting a moving inertia of a feature point. The determining circuit is coupled to the detecting circuit, and arranged for determining an effective sensing region of an image sensing array according to the detected moving inertia for reducing power consumption.
