本发明涉及消费电子领域，尤其涉及的是一种利用眼球跟踪技术控制拍照对焦的方法、系统及拍照设备。
随着拍照设备越来越普及，拍照已经成为人们日常生活中必不可少的功能，具有前后2个摄像头的拍照设备也越来越多。当前拍照设备主要的实现对焦的方式主要为以下2种：
1． 移动拍照设备，根据摄像头所对焦的位置进行对焦；
2． 手动对焦，在预览界面点击需要对焦的图像位置进行对焦。
方法1：移动拍照设备，其摄像头使用光学和数字对焦的算法，但往往不是很准确，而且移动过程中，相机容易抖动，导致对焦点不停变化，不易对焦。

本发明实施例提供的利用眼球跟踪技术控制拍照对焦的系统形成于一终端，所述终端譬如为拍照设备、智能手机或IPAD等等，所述利用眼球跟踪技术控制拍照对焦的系统与上文实施例中的利用眼球跟踪技术控制拍照对焦的方法属于同一构思，在所述利用眼球跟踪技术控制拍照对焦的系统上可以运行所述利用眼球跟踪技术控制拍照对焦的方法实施例中提供的任一方法，其具体实现过程详见所述利用眼球跟踪技术控制拍照对焦的方法实施例，此处不再赘述。
需要说明的是，对本发明实施例的利用眼球跟踪技术控制拍照对焦的方法而言，本领域普通技术人员可以理解实现本发明实施例的利用眼球跟踪技术控制拍照对焦的方法的全部或部分流程，是可以通过计算机程序来控制相关的硬件来完成，所述计算机程序可存储于一计算机可读取存储介质中，如存储在终端的存储器中，并被该终端内的至少一个处理器执行，在执行过程中可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(ROM)或随机存储记忆体(RAM)等。
对本发明实施例的利用眼球跟踪技术控制拍照对焦的系统而言，其各功能模块可以集成在一个处理芯片中，也可以是各个模块单独物理存在，也可以两个或两个以上模块集成在一个模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。所述集成的模块如果以软件功能模块的形式实现并作为独立的产品销售或使用时，也可以存储在一个计算机可读取存储介质中，所述存储介质譬如为只读存储器，磁盘或光盘等。
综上所述，本发明所提供的利用眼球跟踪技术控制拍照对焦的方法、系统及拍照设备，由于采用了拍照设备的前后摄像头同时启动，开始拍照，后摄像头所摄的图像显示在拍照设备的显示屏上，然后人眼看着显示屏上想要对焦的位置，前摄像头拍摄人脸，运用眼球跟踪技术，获取眼球注视的位置数据，将焦点定位在该位置，对焦成功后，直接拍照即可，使拍照设备增加了新功能：通过跟踪眼球的位置来确定对焦位置，实现快而准的对焦，所见即所拍。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
