[0023] [Implementation mode]

[0024] Please refer to Fig. 1, the power saving method of the optical pointing device of the present invention can be used on a computer or video system pointing device. The pointing device perceives the image of an external object through optics, and calculates the correlation between two frames of images to determine The displacement of the optical pointing device controls the cursor on the display screen corresponding to the pointing device, thereby realizing a predetermined function.

[0025] For ease of understanding, the specific application of the present invention will be described below with reference to FIG. 1. FIG. 1 is a block diagram of an existing optical mouse. The mouse 1 includes a control unit 18, an input unit 17, and a light-emitting unit 16, wherein the control unit 18 includes an image The sensor 10, the converter 12, the calculation unit 13, and the communication unit 14. In addition, the mouse 1 further includes a lens 15, whe...

Abstract

The invention discloses a power saving method for an optical indication device, which is used for the indication device of a computer or a video system. Arrays of photosensitive detectors are arranged on the indication device. The photosensitive detectors are used for optically sensing the images of external objects, forming reference frame images and target frame images, and comparing the target frame and the reference frame in the aspect of their relevance so as to determine the motion vector of the objects. When the method disclosed by the invention judges by the above-noted process that the motion vector of the indication device during a preset period of time is zero, the indication device will be ordered to come into a dormant state. And when in dormant state, the indication device will replace the reference frame forcibly to prevent misjudgment whether the indication device needs awaking, thus avoiding wasting power.

Description

【Technical field】 [0001] The present invention relates to a power saving method on an optical pointing device for a computer or video system. 【Background technique】 [0002] An optical pointing device, such as a mouse, is one of the most commonly used human-machine interface devices. When the user moves the mouse on the work surface, the motion sensing device inside the mouse senses the movement, thereby controlling the corresponding movement of the pointer on the computer screen. [0003] 1 is a block diagram of an existing photoelectric mouse. The mouse 1 includes a control unit 18, an input unit 17 and a light emitting unit 16, wherein the control unit 18 includes: an image sensor 10, a converter 12, a computing unit 13 and a communication unit 14. In addition, the mouse 1 also includes a lens 15, wherein the above-mentioned units are all arranged in a housing 3, and the user can hold the housing 3 to move the mouse 1 to control the movement of the cursor on the computer...
