Abstract
The invention provides a light source switching method. The method is applied to a mouse comprising an optical inductor and at least two different light sources. The mouse executes the following steps of: when any one light source in the at least two different light sources is opened, sensing whether the frame speed of an induction image of the optical inductor is smaller than a reset value; and when the sensed frame speed is smaller than the preset value, closing the current opened light source and opening the other light source. The invention also provides a mouse with multiple light sources. When the mouse and method provided by the invention are used on different operation interferes, a proper light source can be selected according to the frame speed of an image sensed by the optical inductor so that the problem of poor induction of the mouse is solved.
Description
Technical field
The present invention relates to a kind of mouse, particularly a kind of mouse and light source changing method that comprises multiple light source and can select a kind of suitable sources automatically.
Background technology
The mouse regular meeting of collocation portable electronic devices (for example notebook computer) uses on the different operation interface because the environment that portable electronic devices uses is different.Because single light source (for example LED ruddiness) is different for the reflection case at different operation interface, in the time of can on some operation interface, using mouse, cause the mouse induction bad.
Summary of the invention
In view of this, thus the present invention provides a kind of can automatically select suitable light source to solve mouse and a kind of light source changing method that mouse responded to bad problem according to operation interface.
The mouse of the multiple light source of said tool comprises an optical sensor.Said mouse also comprises: at least two kinds of different light sources; One light source switch unit is used to control the open and close of said at least two kinds of different light sources; An and controller; Be used for when any light source of said at least two kinds of different light sources is opened; Detect the frame rate of said optical sensor sensed image; And during less than a predetermined value, control a kind of light source that said light source switch unit is closed current unlatching, and open another kind of light source in the said frame rate that detects.
Said light source changing method; This method is applied to a mouse; Said mouse comprises an optical sensor and at least two kinds of different light sources; Said mouse is carried out following steps: when any light source in said at least two kinds of different light sources was opened, whether the frame rate of detecting said optical sensor sensed image was less than a predetermined value; And during less than a predetermined value, close a kind of light source of current unlatching, and open another kind of light source in the said frame rate that detects.
Mouse provided by the invention and method when on the different operating interface, using, can be selected suitable a kind of light source according to the frame rate of optical sensor sensed image, automatically to solve the bad problem of mouse induction.

Embodiment
Please refer to Fig. 1, mouse 100 comprises an optical sensor 10, a controller 20, light source switch unit 30 and at least two kinds of different light sources 40.Said multiple light source 40 can be the different visible light of wavelength, also can be that wherein a kind of light source 40 is infrared light, and other light sources 40 is respectively the different visible light of wavelength.Light source switch unit 30 is selected the open and close of the said multiple light source 40 of control under the control of controller 20.
Fig. 2 is the process flow diagram of light source changing method under one embodiment of the present invention.
Among the step S201, when a kind of light source was opened, whether the frame rate of controller 20 detecting optical sensor 10 sensed image was less than this predetermined value.If, execution in step S202 then, otherwise flow process finishes.
Among the step S202, controller 20 judges whether described all light sources 40 all were unlocked.If judged result is " denying ", execution in step S203 then, if judged result is " being ", execution in step S204.
Among the step S203, controller 20 control light source switch units 30 are closed the light source 40 of current unlatching, open another kind of light source 40, and return execution in step S201.
Among the step S204; Controller 20 control light source switch units 30 select to open a kind of light source 40 wherein; Wherein, when this selecteed light source 40 is opened, the frame rate of the image of optical sensor 10 inductions when the frame rate of optical sensor 10 sensed image is opened greater than other light sources 40.
