OPTICAL NAVIGATION DEVICE WITH ENHANCED TRACKING SPEED
First Claim
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.

Abstract
An optical navigation device for controlling an operation of a pointer on a display apparatus is provided, the optical navigation device includes a device body, a substrate, a light source, an image sensor, and a processing module. The light source, the image sensor, and the processing module are respectively disposed on the substrate. The device body has a housing with an accommodating space formed therein. The substrate is arranged in the accommodating space of the housing. The light source operatively generates a light illuminating a navigation surface of the optical navigation device through the opening of the housing. The image sensor is oriented at a preset angle with respect to a long axis of device body and is configured for capturing images of the navigation surface. The processing module generates a displacement information of the optical navigation device relative to the navigation surface according to the images captured.
