OPTICAL NAVIGATION DEVICE WITH ENHANCED TRACKING SPEED |
摘要 |
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. |

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. |
