Abstract: A mobile terminal having a face recognition function and a control method thereof are provided. A mobile terminal includes a display unit, a memory, a photographing unit and a controller. The memory stores first photographing distance information mapped to a plurality of coordinates in a previously obtained first face image, as reference information for releasing a lock mode in which a touch input applied to the display unit is restricted. The photographing unit obtains a second face image by photographing a subject, when a face recognition function is performed in the lock mode. The controller computes second photographing distance information mapped to the plurality of coordinates in the second face image, and releases the lock mode, based on a result obtained by comparing the first photographing distance information and the second photographing distance information.

Abstract translation: 提供具有人脸识别功能的移动终端及其控制方法。 移动终端包括显示单元，存储器，拍摄单元和控制器。 存储器存储映射到先前获得的第一面部图像中的多个坐标的第一拍摄距离信息，作为用于释放施加到显示单元的触摸输入被限制的锁定模式的参考信息。 当在锁定模式中执行面部识别功能时，拍摄单元通过拍摄对象来获得第二面部图像。 控制器基于通过比较第一拍摄距离信息和第二拍摄距离信息获得的结果来计算映射到第二面部图像中的多个坐标的第二拍摄距离信息，并且释放锁定模式。
