Description

Self-regulating method of a kind of mouse DPI and DPI regulate mouse automatically

Technical field

The present invention relates to mouse, the mouse of particularly a kind of method of in use sensitivity of mouse being controlled automatically and this method of use.

Background technology

Optical mouse mainly is made of tetrameric core component, is respectively light emitting diode (LED), lens subassembly, light engine (Optical Engine) and control chip.

The LED lamp is arranged on the bottom of optical mouse, light is with 30 degree angle directive desktops, irradiate the coarse shade that the surface produced, and then the refraction by the plane sees through other lens and feeds back to and enter on the sensor on the light engine, form by three main subsystems on the light engine:

The IAS system, i.e. imaging system (Image Acquisition System), this be the photoelectricity engine the core, also be the main system of decision photoelectricity engine performance, above-mentioned reflected light enters into the IAS system exactly and handles.

Dsp system, i.e. signal processing system (Digital Signal Processor).Here the image that the IAS system is generated removes and makes an uproar and comparative analysis, draws displacement data, and dsp system is the main arithmetic unit in the photoelectricity engine.The efficiency of algorithm of DSP has determined the data-handling capacity of photoelectricity engine, and the scan-data that the IAS engine can provide is many more, just needs high efficiency DSP ability.

SPI system, i.e. interface system (Serial Peripheral Interface).This is the most traditional system on the photoelectricity engine, and its effect is exactly the push button signalling of the displacement signal of dsp system generation and key system to be encoded be transferred to computer then.

When mouse moves, the pattern that imaging sensor is recorded continuously (DSP) is handled the front and back comparative analysis of every pictures by " digital signal processor ", then with direction and the displacement of judging that mouse moves, thereby draw mouse x, the mobile numerical value of y direction.Pass to the miniature control module (Micro Controller Unit) of mouse again by SPI.The processor of mouse is passed to host computer after these numerical value are handled.

DPI (dot per inch) is a key character parameter of mouse, and it is exactly to reach the effect that changes mouse sensitivity by the sample frequency that changes sensor that DPI switches, to allow mouse adapt to different needs of work.For example when playing games, need mouse to possess very high sensitivity, and in the picture operation, need lower sensitivity.

The sampling precision of mouse sensor on per inch length, 400DPI for example, mouse whenever move 1 inch coordinate that can feed back 400 differences, and promptly Ding Wei minor increment is 1/400 inch (about 0.0635 millimeter), be reflected on the display, mouse moves 400 points.800DPI, mouse whenever move 1 inch coordinate that can feed back 800 differences, are reflected on the display, and mouse moves 800 points.Under the identical situation of exploration on display resolution ratio, for example 1024X 768, and this moment, the anchor point of display screen also was identical, and DPI is high more, and mouse is just sensitive more.

Most on the market conventional mouse all is by a special DPI switching push button now, selects different sensitivity by the client according to the needs of oneself, to adapt to the demand of oneself working.But in the software application environment of reality, never be single non-be slow state soon, even the reaction that also can need mouse to make sometimes in same software environment to be exceedingly fast needs mouse to make accurate location with slower speed sometimes.Therefore, such mouse all can not satisfy user's needs.
