Claim One:
1. An optical navigation device, adapted to control an operation of a pointer on a display apparatus, the optical navigation device comprising: a device body comprising a housing with an opening, the housing having an accommodating space formed therein; a substrate having a lower surface, arranged in the accommodating space of the housing; a light source disposed on the lower surface of the substrate, operatively generating a light illuminating a navigation surface of the optical navigation device through the opening of the housing; an image sensor disposed on the lower surface of the substrate, operatively capturing a plurality of images responsive to a reflected light reflected from the navigation surface to generate a plurality of frames according to a predetermined frame rate, wherein the image sensor is oriented at a preset angle with respect to a long axis of the device body; and a processing module disposed on the lower surface of the substrate and coupled to the light source and the image sensor, the processing module operatively generating a displacement information of the optical navigation device relative to the navigation surface according to at least one of the plurality of frames.
