下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
请参见图1，图1为现有眼球识别装置的结构示意图。现有设置在手机上的眼球识别装置包括眼球摄像头11以及红外补光灯12，受手机结构的限制，眼球摄像头11以及红外补光灯12会分开设置。由于眼球摄像头11具有一摄像区域，红外补光灯12具有一补光区域，当眼球摄像头11和红外补光灯12的距离较大时，摄像区域和补光区域的重叠区域会距离手机较远，这样会导致由于识别距离较远而无法进行准确的眼球识别，如区域A所示，或由于红外补光灯12无法充分发挥补光的作用而不能进行准确的眼球识别，如区域B所示，因此，现有的应用在手机上的眼球识别装置无法近距离准确地进行眼球识别。Please refer to FIG. 1. FIG. 1 is a schematic structural view of a conventional eyeball recognition device. The eyeball recognition device currently installed on the mobile phone includes an eyeball camera 11 and an infrared supplemental lamp 12, which are separately arranged by the structure of the mobile phone, and the eyeball camera 11 and the infrared supplemental lamp 12 are separately disposed. Since the eyeball camera 11 has an imaging area, the infrared fill light 12 has a fill light area. When the distance between the eyeball camera 11 and the infrared fill light 12 is large, the overlapping area of the image capturing area and the fill light area is far from the mobile phone. This will result in accurate eye recognition due to the long recognition distance, as shown in area A, or because the infrared fill light 12 cannot fully perform the fill light, and accurate eye recognition cannot be performed, as shown in area B.
