指紋傳感器(FPS200) 運用圖像搜索技術,通過改變傳感器電容陣列參數,能在1 s 內掃描多幀指紋圖像,并自動選擇質量最好的供后端進行相應處理,顯著減低系統誤識率、拒識率。主要介紹基于該傳感器開發的“指紋鼠標”。根據鼠標內部較大空間、傳感器FPS200 及微處理器體積很小的特點,將三者集成為集鼠標與用戶身份識別功能于一體,既方便快捷、又唯一可靠。實踐證明,它能為計算機用戶提供完善的身份認證,在諸多領域有著極其廣泛的用途。

Abstract : By using the image seek technology to change the capacity array parameter of the fingerprint sensor , FPS200 can scan the fingerprint diagram of many frames in a second ,and automatically choosing the best image to treat . The FAR and the FRR of the system can be widely reduced in the practice.“Fingerprint mouse”which base on the sensor is introduced. The mouse has been made possible by taking account of the roomy space within mouse ,tiny chip patch for sensor FPS200 ,together with small size of available microprocessors ,The usage of this device is very easy and reliable. It can provide perfect identity for computer user ,and there is very extensive using in many realms.
