Abstract
A display apparatus having a sensor and camera and a control method thereof are provided. Exemplary embodiments relate to a display apparatus and a control method thereof which determines through a sensor, such as a pyroelectric infrared ray (PIR) sensor, and a camera, whether a user intends to use the display apparatus, and drives the display apparatus based on the users intentions in order to reduce booting time.
Claims13
A display apparatus comprising:
- at least one sensor configured to sense a motion within a predetermined distance in at least one of front, left and right directions, while in an activated state without supplying power to the display apparatus except for the at least one sensor;
- at least one camera configured to extract image information related to an object;
- and
- a central processing unit (CPU) configured to be activated by a sensing signal from the at least one sensor based on the sensing signal which is sensing the motion of the object, to control power supplied to the at least one camera to be activated in response to the CPU being activated, and to performs a security operation according to an analysis result of the image information related to the object provided by the camera.
A method of controlling a display apparatus the method comprising:
- activating a sensor without supplying power to the display apparatus except for the sensor;
- transmitting a sensing signal of the sensor to a central processing unit (CPU) in order to activate the CPU based on the sensing signal which is sensing a motion of an object;
- controlling power supplied to a camera by the CPU in response to the CPU being activated, the CPU being activated by the sensing signal and receiving from the camera image information related to the object located in front of or near the display apparatus;
- searching for the image information related to the object from a database by the CPU;
- and
- performing a security function in response to no corresponding image information being found.
A display apparatus for reducing booting time, the display apparatus comprising:
- at least one sensor configured to sense a motion within a predetermined distance, while in an activated state without supplying power to the display apparatus except for the at least one sensor;
- a camera configured to extract image information related to an object located in front of or near the display apparatus;
- and
- a central processing unit (CPU) configured to be activated by a sensing signal from the at least one sensor based on the sensing signal which is sensing the motion of the object, to control power supplied to the camera to be activated in response to the CPU being activated, and to perform a security operation according to an analysis result of the image information related to the object provided by the camera.
