June 25, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors NA, Moon-sung (Suwon-si, KR); KANG, Keun-seok (Yongin-si, KR); SEO, Je-hwan (Suseong-gu, KR); HA, Tae-hyeun (Suwon-si, KR), filed on October 10, 2013, was made available online on June 12, 2014.

The patent's assignee is Samsung Electronics Co., Ltd.

News editors obtained the following quote from the background information supplied by the inventors: "Apparatuses and methods consistent with the exemplary embodiments relate to a display apparatus and a control method thereof. More particularly, exemplary embodiments relate to a display apparatus and a control method thereof which determines, through a pyroelectric infrared ray (PIR) sensor and a camera, whether a user intends to use the display apparatus, and drives the display apparatus in advance of the user request in order to reduce booting time.

"The development of technology has encouraged development of various display apparatuses. A user generally uses a remote controller to turn on a TV. In response to the user pressing an ON button from the remote controller, the TV receives a signal from the remote controller through an infrared sensor. Then, the TV begins its driving operation.

"From the time the user presses the button on the remote controller to the time when a normal TV screen is driven through a TV panel, booting time is required. However, the user may feel that the booting time takes too long."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "Accordingly, one or more exemplary embodiments provide a display apparatus and a control method thereof which reduces booting time.

"Another exemplary embodiment is to provide a display apparatus and a control method thereof which performs a security function.

"Still another exemplary embodiment is to provide a display apparatus and a control method thereof which consumes less power.

"Yet another exemplary embodiment is to provide a display apparatus and a control method thereof which promotes the convenience of users.

"The foregoing and/or other aspects of the exemplary embodiments may be achieved by providing a display apparatus including: a display; 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; a camera configured to extract image information of an object located in front of the display apparatus; and a central processing unit (CPU) configured to be activated by a sensing signal from the at least one sensor, activates the camera, and controls power supplied to the display according to an analysis result of the image information of the object provided by the camera.

"According to an aspect of another exemplary embodiment, the CPU identifies whether the object is a human or a pet.

"According to an aspect of another exemplary embodiment, the CPU determines supply power to the display according to whether the object intends to use the display apparatus, in response to an identification that the object is the human. The foregoing and/or other aspects of the exemplary embodiments may be achieved by providing a display apparatus including: 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; at least one camera configured to extract image information of an object; and a central processing unit (CPU) configured to be activated by a sensing signal from the at least one sensor, activates the at least one camera, and performs a security operation according to an analysis result of the image information of the object provided by the camera.

"According to an aspect of another exemplary embodiment, the security function may include at least one of outputting a warninging sound, outputting a warning screen, a recording function, and external transmission of data.

"According to an aspect of another exemplary embodiment, the data transmitted to the outside may include information that has been recorded by the camera.

"According to an aspect of another exemplary embodiment, the CPU compares the image information of the object with stored image information in order to determine whether to perform the security function.

"According to an aspect of another exemplary embodiment, the CPU selects and activates the at least one camera in the same direction as the at least one sensor having the sensing signal.

"According to an aspect of another exemplary embodiment, the sensor may include one of an infrared sensor, a broadband RF sensor, a radar sensor and an ultrasonic sensor.

"According to an aspect of another exemplary embodiment, the sensor is activated through a graphic user interface (GUI).

"The foregoing and/or other aspects of the exemplary embodiments may be achieved by providing a control method of a display apparatus including: activating a sensor, transmitting to a central processing unit (CPU) a sensing signal of the sensor in order to activate the CPU; activating a camera by the CPU activated by the sensing signal and receiving from the camera image information of an object located in front of the display apparatus; analyzing the received image information of the object by the CPU; and controlling power supplied to a display according to an analysis result by the CPU.

"According to an aspect of another exemplary embodiment, the CPU supplies power to the display in response to an identification, through the analysis of the image information of the object, that the object intends to use the display apparatus.

"The foregoing and/or other aspects of the exemplary embodiments may be achieved by providing a control method of a display apparatus including: activating a sensor, transmitting a sensing signal of the sensor to a central processing unit (CPU) to activate the CPU; activating a camera by the CPU, the camera being activated by the sensing signal and receiving from the camera image information of an object located in front of the display apparatus; the CPU searching a database for image information related to the object ; and performing a security function in response to no corresponding image information being found.

"Another exemplary embodiment may provide a display apparatus for reducing booting time, the display apparatus including: at least one sensor configured to sense a motion within a predetermined distance, while in an activated state; 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, activate the camera, and performs a security operation according to an analysis result of the image information related to the object provided by the camera. Power may be turned off except for minimal power to the sensor, prior to the CPU receiving a signal from the sensor.

"The CPU may be configured to identify whether the object is a human or a pet, and the security function may include at least one of outputting a warning sound, outputting a warning screen, a recording function and external transmission of data.

"The CPU may compare the image information of the object with stored image information in order to determine whether to perform the security function.
