Abstract
Disclosed are a mobile terminal and a method for controlling the same. The mobile terminal includes: a terminal body; a camera; a sensor configured to sense a raising gesture of the terminal body; and a controller configured to: activate the camera in response to the raising gesture; detect a face within an image received via the camera; and release a locked state of the mobile terminal based on a face recognition of the detected face.
Claims15
A mobile terminal, comprising:
- a terminal body;
- a camera;
- a sensor configured to sense a raising gesture of the terminal body;
- a touch screen;
- and
- a grip sensor provided on a side surface of the terminal body;
- a controller configured to:
- determine an occurrence of the raising gesture when a gripped state of the terminal body by a user's hand is sensed by the grip sensor and a degree of a touch input received via the touch screen exceeds a reference pressure;
- activate the camera in response to the determination of the raising gesture;
- detect a face within an image received via the camera;
- perform fingerprint recognition, via a fingerprint sensor of the mobile terminal, based on a second touch input to the touch screen while the face is being detected within the image received via the camera;
- and
- release a locked state of the mobile terminal based on successful fingerprint recognition in addition to successful face recognition of the detected face,
- wherein if the face detection is unsuccessful for at least a predetermined time, the controller is further configured to perform a command for updating a notification, control the touch screen to display information regarding the updated notification, and to convert the mobile terminal into a sleep mode after the predetermined time lapses.

A mobile terminal, comprising:
- a terminal body;
- a touch screen;
- a grip sensor provided on a side surface of the terminal body;
- a camera configured to maintain a constant activated state in a low-power mode;
- a sensor configured to sense a raising gesture of the terminal body, wherein the raising gesture corresponds to a movement of the mobile terminal which exceeds a threshold angle change and exceeds a threshold distance change within a reference time;
- and
- a controller configured to:
- determine an occurrence of the raising gesture when a gripped state of the terminal body by a user's hand is sensed by the grip sensor and a degree of a touch input received via the touch screen exceeds a reference pressure;
- detect a face within an image received via the camera in response to the determination of the raising gesture;
- control the touch screen to display a lock screen when the face is detected within the image received via the camera;
- perform fingerprint recognition, via a fingerprint sensor of the mobile terminal, based on a second touch input to the touch screen while the face is being detected within the image received via the camera:
- and
- release a locked state of the mobile terminal based on the fingerprint recognition in addition to face recognition of the detected face,
- wherein if the face recognition is unsuccessful for at least a predetermined time, the controller is further configured to perform a command for updating a notification, control the touch screen to display information regarding the updated notification, and to convert the mobile terminal into a sleep mode after the predetermined time lapses.
