Zusammenfassung:	Provided are a recognition method and a recognition system using a diffusing lens. A lighting device emits light to an object. A camera generates an image by photographing the object, and a recognition device recognizes information from the photographed image. When the light output from the lighting device is focused on a specific part of the object, the recognition of information from the photographed image may be impossible or erroneous. In order to prevent the concentration of such light, the diffusing lens diffuses the light in a specific direction. 확산 렌즈를 사용하는 인식 방법 및 인식 시스템이 제공된다. 조명 장치는 대상으로 광을 발한다. 카메라는 대상을 촬영함으로써 이미지를 생성하고, 인식 장치는 촬영된 이미지로부터 정보를 인식한다. 조명 장치에 출력되는 광이 대상의 특정 부분에 집중되면 촬영된 이미지로부터의 정보의 인식이 불가능해지거나 잘못될 수 있다. 이러한 광의 집중을 방지하기 위해 확산 렌즈는 광을 특정 방향으로 확산시킨다.
