`
`[0002] TECHNICAL—FIELD
`
`BACKGROUND
`
`[0003] The—present—Exemplam embodiments of the invention relates—relate generally to
`
`an event search system, device, and method, and more-pafiieul-arl—y specifically, to an event
`
`system, device, and method capable of deriving only events that have occurred within a search
`
`area as a search result by a user specifying an area intended to be searched as the search area
`
`after an event occurs.
`
`[0004] DISCUSSION OF THE BACKGROUND [[ART]]
`
`[0005] Generally, surveillance systems are being widely used in a variety of locations
`
`including banks, department stores, and general residential areas. Such a surveillance system
`
`may be used for the purpose of crime prevention, security, or the like, but recently is also used to
`
`surveil a pet or a child indoors in real time. Also, a system that is most widely used as such a
`
`surveillance system is a closed circuit television (CCTV) system, in which a camera is installed
`
`at an appropriate location to capture an image of an area which a user desires to be under
`
`surveillance, after which the user may surveil the area by monitoring the image captured by the
`
`camera.
`
`[0006] Recently, such CCTV systems provide an event search function. An event refers
`
`to a number of various events that occur while a camera is capturing a specific area. For
`
`example, such events include a motion event in which a person or animal moves, a motion and
`
`sound event in which a glass falls from a cupboard and then breaks, a heat and light event in
`
`which a fire occurs, and the like. Recently, CCTVs are connected to various sensors to provide
`
`an event notification function in which, when a specific event occurs, the sensors detect the event
`
`and inform a user that the event has occurred.
`
`

`

`Attorney Docket No.: P8150USOO
`Substitute Specification (Marked-up)
`
`[0007] However, when an event has already occurred, a user may hope to check details
`
`of the event having occurred. As an example, it is assumed that a vase is broken in a living room
`
`when a user comes back home. In this case, the user may wish to monitor which events have
`
`occurred in the past. However, conventionally, in order to search for such an event, a user could
`
`enter only a time condition.
`
`[0008] Alternatively, even when a location condition is allowed to be entered, a user
`
`cannot enter the location condition after an event has occurred. That is, when a user sets an area
`
`of interest (ROI) in advance, later, the user can only search for an event having occurred in the
`
`ROI. Thus, later, there is a need to enter a location condition as one search condition in order to
`
`search for an event having occurred in a specific area in the past.
`
`[0009]
`
`
`
`information disclosed in this Background section is only for understanding of the background of
`
`the inventive concepts, and, therefore, it may contain information that does not constitute p_rior
`
`a_rt.

`
`[0010] Devices and methods constructed according to exemplam implementations of the
`
`invention are capable of providing an event search, device, and method capable of deriving only
`
`an event having occurred in a search area as a search result by a user specifying, as the search
`
`area, an area to be searched after an event occurs.

`
`[0058] The terminology used herein is for the purpose of describing particular
`
`embodiments only and is not intended to be limiting of the invention. As used herein, the
`
`singular forms "a,
`
`an," and "the" are intended to include the plural forms as well, unless the

`
`[0059] Hereinafter, exemplary embodiments of the present invention will be described in
`
`detail with reference to the accompanying drawings.
`
`[0060] FIG. 1 is a block diagram showing a configuration of an event search system
`
`according to an embodiment of the present invention, and FIG. 2 is a perspective view of an
`
`event search device 1 of FIG. 1.
`
`[0061] Based on a method using the event search system according to an embodiment of
`
`the present invention, an event search area 116 is displayed on a screen unit 11 of the event
`
`search device 1. Also, by using the event search area 116, a user may easily specify a location
`
`condition to search for an image 112 captured and stored in advance of an event or the like
`
`generated at a specific location. In this case, without directly searching for images 112 in which
`
`an event occurrence is recorded, the event search device 1 may search for only metadata in
`
`which an event has occurred by using pre-generated metadata and quickly output a search result.
`
`[0062] The event search system according to an embodiment of the present invention
`
`includes a camera 2 configured to capture a specific area to acquire an image 112, a sensor 3
`
`configured to transmit a signal when an event occurrence is detected, and the event search device
`
`1, which receives and displays the image 112 acquired by the camera 2 and receives the signal
`
`

`

`Attorney Docket No.: P8150USOO
`Substitute Specification (Marked-up)
`
`transmitted from the sensor 3. The camera 2 or the sensor 3 and the event search device 1 may
`
`be connected to each other in a wired or wireless manner to transmit or receive image data or
`
`signals.
`
`[0063] The camera 2 captures a specific area to acquire an image 112. The camera 2
`
`according to an embodiment of the present invention may be a pan-tilt camera capable of
`
`panning and tilting. Alternatively, the camera 2 may be a 360-degree camera that is recently
`
`introduced. A 360-degree camera is a camera 2 capable of simultaneous omni-directional
`
`capturing by having a plurality of fish-eye lenses without physically panning or tilting. In this
`
`case, an image 112 acquired by a 360-degree camera is panned or tilted using software installed
`
`in the event search device 1. The camera 2 according to an embodiment of the present invention
`
`is not limited thereto, and various cameras may be used as the camera 2.
`
`[0064] The camera 2 according to an embodiment of the present invention may be a
`
`digital camera configured to capture two-dimensional (2D) pictures at 15 to 30 frames per
`
`second, perform digital conversion on the pictures, and then output video data, but the present
`
`invention is not limited thereto. When the camera 2 is not a digital camera, a captured image is
`
`an [[RBG]]@ analog image signal, so an analog-to-digital (A/D) converter should be provided
`
`separately. On the other hand, when the camera 2 is a digital camera, there is no need for the
`
`A/D converter. Also, the camera 2 has an image encoding function installed therein, and thus
`
`when an image is captured, the camera 2 encodes the image immediately to generate compressed
`
`image data.
`
`[0065] The image 112 captured by the camera 2 is transmitted to the event search device
`
`1 through wired or wireless communication and displayed through the screen unit 11 built in the
`
`event search device 1. However, when the camera 2 is mounted on the event search device 1, the
`
`image 112 captured by the camera 2 may be transmitted to the screen unit 11 through an internal
`
`circuit, not through wireless communication, and then displayed.
`
`[0066] The sensor 3 may detect an event. For example, the sensor 3 includes a fire
`
`detection sensor 3 for detecting occurrence of a fire, a smoke detection sensor for detecting
`
`occurrence of smoke, a heat or motion detection sensor 3 for detecting appearance of a person or
`
`animal, or the like. In addition, recently, an Internet of Things (IoT) network in which
`
`information is exchanged between distributed elements, such as objects, is being developed. The
`
`sensor 3 according to an embodiment of the present invention may be a sensor 3 that is built in
`
`

`

`Attorney Docket No.: P8150USOO
`Substitute Specification (Marked-up)
`
`an IoT-dedicated module in order to implement IoT technology. That is, the sensor 3 is not
`
`limited thereto, and various kinds of sensors 3 may be used as long as the sensors 3 detect any
`
`kinds of events.
`
`[0067] The event search device 1 according to an embodiment of the present invention
`
`may detect an event occurrence when no sensor 3 is present. That is, when an event occurs while
`
`the camera 2 is capturing a specific area, the event occurrence is detected and analyzed through
`
`the image 112 acquired by the camera 2 even without the sensor 3. The method of detecting the
`
`event occurrence through the image 112 will be described below.
`
`[0068] The event search device 1 receives and displays the image 112 acquired by the
`
`camera 2 and then receives a user's input and searches for an event. The event search device 1
`
`may be a device that is portable and easy to move, such as a smartphone, a tablet PC, and a
`
`laptop, but the present invention is not limited thereto. The event search device 1 may also be a
`
`device that is not easy to move, such as a desktop and a video wall.
`
`[0069] As shown in FIG. 1, the event search device 1 includes a main body 10, a screen
`
`unit 11 configured to display an image 112, a first communication unit 12 configured to receive
`
`image data and signals from a camera 2 and a sensor 3, a storage unit 13 configured to store the
`
`image 112, and a control unit 14 configured to control the other elements.
`
`[0070] The screen unit 11 displays the image 112 acquired by the camera 2. The image
`
`112 may be a real-time image 112 that is captured and acquired by the camera in real time and
`
`also may be an image 112 that has been already captured and stored in the storage unit 13 and
`
`then is loaded and displayed. Also, the screen unit 11 displays the event search area 116 so as to
`
`facilitate a search for the stored image 112 or event. When the event search device 1 provides a
`
`touch function, the screen unit 11 may include a touch sensor 111. In this case, a user may
`
`directly enter a touch signal through the screen unit 11. The touch sensor 111 may be integrated
`
`with the screen unit 11 and is configured to detect a touch generated on the screen unit 11, detect
`
`coordinates of an area where the touch is generated, the number of touches, touch strength, and
`
`the like, and deliver a result of the detection to the control unit 14. Depending on the manner in
`
`which the touch sensor 111 detects a touch, various types such as capacitive type, resistive type,
`
`ultrasonic type, and infrared type may be used. Although the event search device 1 provides a
`
`touch function, the screen unit 11 may not include the touch sensor 111. In this case, a separate
`
`touch pad may be provided as an input unit. Also, the touch may be made with a human finger,
`
`

`

`Attorney Docket No.: P8150USOO
`Substitute Specification (Marked-up)
`
`but the present invention is not limited thereto. A stylus pen equipped with a tip capable of
`
`conducting a micro current may be used. When the event search device 1 does not provide a
`
`touch function, an input unit capable of receiving a user's command, such as a mouse, may be
`
`separately provided.
`
`[0071] The first communication unit 12 may transmit and receive signals and data to and
`
`from the camera 2 and the sensor 3 in a wired or wireless manner. For example, the first
`
`communication unit 12 modulates signals and data received from the control unit 14, performs
`
`frequency up-conversion on the signals and data, and then transmits the signals and data, or
`
`performs down-conversion on signals and data received from the camera 2 and the sensor 3,
`
`demodulates the signals and data, and provides the signals and data to the control unit 14.
`
`Through this process, the first communication unit 12 may receive an image 112 or data from the
`
`camera 2 or receive a signal of the sensor 3 and may transmit data or signals generated by the
`
`control unit 14 to the camera 2 or the sensor 3.
`
`[0072] The storage unit 13 stores programs for processing and controlling operations of
`
`the event search device 1, various kinds of data generated while each program is being
`
`performed, and image data transmitted through the camera 2. The storage unit 13 may be built in
`
`the event search device 1. However, a separate device such as a network video recorder (NVR)
`
`may be provided for a system having a network camera 2.
`
`[0073] The control unit 14 controls the overall operation of the event search device 1.
`
`For example, the control unit 14 performs processing and control for signal and data
`
`communication between the first communication unit 12 and the camera 2 and performs
`
`processing, such as decoding and rendering, of images 112 when the image 112 is transmitted
`
`through the first communication unit 12. Also, the control unit 14 controls the screen unit 11 to
`
`display the event search area 116 and searches for events having occurred in the event search
`
`area 116 during a specific period when the event search area 116 is set. Also, the control unit 14
`
`controls the storage unit 13 to store the image 112 and load the stored image 112. {Hrs—preferable
`
`that—a—Acentral processing unit (CPU), a micro control unit (MCU), or a digital signal processor
`
`(DSP) be used as the control unit 14 according to an embodiment of the present invention, but
`
`the present invention is not limited thereto. Various logical operation processors may be used.
`
`[0074] The control unit 14 includes a gesture detection unit 141 and a coordinate
`
`transformation unit 142. The gesture detection unit 141 detects a touch gesture from the touch
`
`10
`
`

`

`Attorney Docket No.: P8150USOO
`Substitute Specification (Marked-up)
`
`sensor 111. The touch gesture includes any touch operations arising from the touch sensor 111.
`
`When the event search device 1 does not provide a touch function, a user command received
`
`through an input unit, such as a mouse, is detected. The gesture detection unit 141 manages the
`
`touch sensor 111 and includes an application program interface (API) for a user to easily use a
`
`touch gesture in an application. An API refers to an interface for controlling a function that is
`
`provided by an operating system or a programming language so that the function may be used in
`
`an application program. Though the API, the gesture detection unit 141 receives a user
`
`command for executing an application for controlling the camera 2 and a user command for
`
`controlling an activated application.
`
`[007 5] The coordinate transformation unit 142 receives coordinates at which a user
`
`command is entered from the gesture detection unit 141 and generates a location change value of
`
`the event search area 116 on the basis of the coordinates. When a user touches one joint 1161 of
`
`the event search area 116 in order to specify the location condition, the coordinates of the joints
`
`1161 are extracted. Then, when the user drags the joint 1161, coordinates along a path of the
`
`dragging are extracted at every cycle or interval. The coordinate transformation unit 142 may
`
`recognize a direction and distance in which the dragging is made through the extracted
`
`coordinates and may transform the direction and distance into a value to which the location of
`
`the joint 1161 should be changed. By changing the location of the joint 1161 by using the value
`
`and then displaying the joint 1161 through the screen unit 11, it is possible to specify the location
`
`condition according to the user's command.

`screen unit 11 of the event search device 1 according to an embodiment of the present invention.
`
`[0077] When the event search device 1 according to an embodiment of the present
`
`invention is executed, a live view is initially displayed through the screen unit 11. At the same
`
`time, the start icon 113 is displayed. The start icon 113 is displayed on one side edge of the

`
`screen unit 11 as a result of the tapping shown in FIG. 4.
`
`[0079] Tapping, which is one touch gesture, refers to shortly touching the screen unit 11
`
`and removing the touch in a short time. Generally, a touch duration of tapping is less than one
`
`second. It is assumed that tapping is consecutively executed several times in a short time period.
`
`The tapping is referred to as a double tap when the tapping is made two times and is referred to
`
`as a triple tap when the tapping is made three times.
`
`[0080] When a user taps the start icon 113, the menu wheel icon 114 is displayed at a
`
`location where the start icon was displayed. Accordingly, like the start icon 113, the menu wheel
`
`icon 114 may be displayed on one side edge of the screen unit 11 of the event search device 1.
`
`Also, since the menu wheel icon 114 is displayed, the start icon 113 may disappear. It is
`
`assumed that a user can enter a command to the event search device 1 by means of a mouse.
`
`When the user clicks the start icon 113, the menu wheel icon 114 may be displayed.
`
`[0081] The menu wheel icon 114 may be formed using dots and lines so as to not
`
`obstruct the user’s monitoring of the image 112 being displayed. The menu wheel icon 114 may
`
`be semi-circular as shown in FIG. 5, but the present invention is not limited thereto. The menu
`
`wheel icon 114 may have various shapes such as a triangle, a rectangle, and the like.
`
`[0082] Various menus are displayed on the menu wheel icon 114 so that the user may
`
`select one of the menus. For example, the menus include Live View, Event, Play Back, Settings,
`
`etc. Also, each menu is composed of a point formed as a selection area to be selected by a user
`
`and a phrase indicating the name of a corresponding menu. When a user taps or clicks any menu
`
`of the menu wheel icon 114, the menu is selected. Also, when a user drags the menu wheel icon
`
`114 upward or downward, the menu wheel icon 114 rotates in a direction in which the dragging
`
`is made, and the locations of the menus change.
`
`[0083] Live View refers to an image 112 of an area currently captured by the camera 2
`
`being displayed on the event search device 1 in real time. Play Back refers to an image 112 that
`
`is previously captured, stored in the storage unit 13, loaded by the event search device 1, and
`
`then displayed. Event refers to data that records a specific accident that has occurred. For
`
`example, when a specific motion is captured in a house where no one is present, the location and
`
`time at which the motion is captured are automatically recorded as data. Setting refers to a menu
`
`for a user to change various kinds of options desired by the user. The menus displayed on the
`
`menu wheel icon 114 are not limited thereto, and various kinds of menus may be present.
