Hereinafter, embodiments of the present invention will be described in detail and in detail so that those skilled in the art can readily implement the present invention.
1 is a diagram showing an example in which an image storage device according to an embodiment of the present invention is installed. Referring to FIG. 1, the image storage device 100 may be installed around a door or a door of a building such as an apartment, a house, or a company. The image storage device 100 can store an image of a person or an animal around the door using a camera. For example, the image storage device 100 may capture and store an image of a person approaching a door for various purposes, such as a person passing through a door, a courier, a delivery person, or a criminal. That is, the image storage device 100 can capture and store an image of an external object when a movement of an external object outside the door is detected.
In this specification, an external object means a person, an animal, an object, or the like, from which movement can be detected outside or near a door, and includes a person who has visited for a specific purpose and a person who passes without a specific purpose.
The image storage device 100 may include components and devices that perform various functions. As shown in FIG. 1, the image storage device 100 may be in a form in which several components and devices are packaged and implemented as a single device. In addition, the components and devices constituting the image storage device 100 according to the present invention may exist separately as separate parts or devices in the vicinity of a door or a door. For example, if the image storage device 100 includes a camera, the camera may be separately installed in the packaged image storage device 100, around a door or a door, and included in the image storage device 100.
Also, the image storage device 100 according to the embodiment of the present invention can photograph an image of an external object using a camera existing around a door or a door. In this case, the image storage device 100 may not include a camera.
The image storage device 100 may be installed at a door, and may store an image of a detected external object by sensing movement of the external object. In addition, the image storage device 100 can conveniently provide an image of a stored external object to a user. For example, as shown in FIG. 1, when the user enters or exits the house through a door, the image storage device 100 can communicate with the user's terminal 200. The image storage device 100 may provide an image of an external object to the terminal 200 of a communication-connected user. A user who has received an image from the image storage apparatus 100 can easily check external object information by checking the image on the terminal 200. [ In particular, since the user can receive the external object information immediately after returning from the outing, the external object information can be checked at the most questionable time whether or not the external object exists.
In this specification, the user includes all persons using the space inside the door such as the owner of the house, the owner of the building, and the like. That is, the user may refer to all persons who need to identify external objects. In addition, the terminal 200 includes all kinds of electronic devices capable of communicating with the image storage device 100 such as a user's smart phone, tablet PC, notebook computer, and the like.
Hereinafter, each configuration of the image storage device 100 will be described in detail with reference to FIG. 2 to FIG.
2 is a block diagram of an image storage device according to an embodiment of the present invention. 3 is a diagram illustrating an example of external object information stored in an image storage device according to an embodiment of the present invention. 2, the image storage device 100 includes a motion sensor 110, an acceleration sensor 120, a camera 130, an alarm 140, a communication module 150, a controller 160, and a memory 170 ).
The motion sensor 110 detects movement of an external object. For example, the motion sensor 110 may be a passive infrared (PIR) sensor that detects movement of an external object using infrared rays. The motion sensor 110 of the present invention may include not only an infrared ray detection sensor but also all kinds of motion detection sensors capable of detecting motion.
The acceleration sensor 120 senses the movement of the door. For example, the acceleration sensor 120 may be a three-axis gyro acceleration sensor, and can detect the movement of the door from the magnitude of the door movement in the x-, y-, and z-axis directions. The acceleration sensor 120 of the present invention may include not only a three-axis gyro acceleration sensor but also all kinds of acceleration sensors capable of detecting movement of a door.
The motion sensor 110 and the acceleration sensor 120 may transmit the measured values of the motion of the detected external object and the movement of the door to the controller 160.
The camera 130 takes an image of the vicinity of the door. The camera 130 can continuously capture an image while the power of the image storage device 100 is turned on, but can perform an image capturing operation only under a specific condition under the control of the controller 160. [ For example, the camera 130 may capture an image only when there is movement of an external object sensed by the motion sensor 110. The controller 160 may control the operation of the camera to reduce power consumption according to the operation of the camera 130. The image photographed by the camera 130 may be stored in the memory 170. [
When there is a surveillance camera such as a CCTV in the vicinity of the door, the image storage device 100 may not include the camera 130. The image storage apparatus 100 can acquire an external object image by communicating with an external camera through the communication module 150. [
The alarm 140 outputs an alarm sound. The alarm 140 can output an alarm sound when a specific situation occurs under the control of the controller 160. [ For example, when the movement of the door is detected through the acceleration sensor 120, the alarm 140 may output an alarm sound. In addition, when the movement of the door is detected, and the image stored in the memory 170 exists, the alarm 140 may output an alarm sound. The user can recognize whether or not an external object exists from the alarm sound.
The user can set the terminal 200 so that the terminal 200 can communicate with the image storage device 100 when an alarm sound is output. For example, the user can activate the Bluetooth of the terminal 200 and set the terminal 200 in a Bluetooth connection with the image storage device 100. When the terminal 200 and the image storage apparatus 100 are connected to each other for the first time, the user can search for the image storage apparatus 100 in the terminal 200, enter a password, and establish a communication connection. After the first connection, the image storage device 100 can be communicatively coupled to the terminal 200 without any additional operation.
The communication module 150 communicates with devices outside the user terminal 200 or the image storage device 100 by transmitting and receiving data. The communication module 150 can communicate with external devices such as a CCTV not included in the user terminal 200 and the image storage device 100. The communication module 150 may transmit the external object information stored in the memory 170 to the user terminal 200. [ For example, as shown in FIG. 3, the communication module 150 may transmit to the user terminal 200 information that matches the shooting time and the external object image.
In addition, the communication module 150 may receive data on the operation of the image storage device 100 from the user terminal 200. [ For example, the user can request the storage image transmission through his / her terminal 200, and when the communication module 150 receives a request for image transmission from the user terminal 200, The stored image can be transmitted.
The communication module 150 may be a wireless communication module such as a Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), Wireless Broadband Internet (WiBro), Wireless Fidelity (WiFi), Bluetooth, Near Field Communication (NFC), and ZigBee ), And so on. The communication module 150 can perform communication with the user terminal 200 or the surveillance camera through the short-range communication method among various wireless communication methods. For example, the communication module 150 may be a Bluetooth low energy (BLE) module for short-range communication. The communication module 150 can perform power communication with the user's terminal 200 only when the user exits or enters the door, thereby reducing power consumption.
The controller 160 controls the operation of components included in the image storage device 100. When motion of an external object is detected from the motion sensor 110, the controller 160 may transmit an image capturing command to the camera 130. [ Illustratively, the controller 160 may send an image capture command to the camera 130 when the first motion is detected, if the motion of the external object is detected multiple times within a predetermined time. The controller 160 may store the photographed image in the memory 170. For example, as shown in FIG. 3, the controller 160 may store the image capturing time and the captured image in the memory 170 in a matching manner.
The controller 160 can reduce the power consumption according to the operation of the camera 130 by controlling the image capturing operation of the camera 130. [ Accordingly, the controller 160 can store an external object image using the small-capacity memory 170 by storing a small number of images in the memory 170. [
The controller 160 can determine whether the door is opened or closed when the movement of the door is detected by the acceleration sensor 120. [ The controller 160 may control the alarm 140 so that the alarm 140 outputs an alarm sound when the door is opened or closed. In addition, the controller 160 may cause the alarm sound to be output when there is an image stored in the memory 170 when the door is opened or closed. The controller 160 may output an alarm sound and may be connected to the user terminal through the communication module 150. [
The user can recognize whether or not the stored external object image exists through the alarm sound. The user can set the terminal 200 so that the terminal 200 can communicate with the image storage device 100. [ For example, the user can activate the Bluetooth of the terminal 200, and the terminal 200 can receive external object information stored in the Bluetooth connection with the image storage device 100.
The memory 170 stores the photographed image. The memory 170 may store an external object image photographed by the camera 130 and a time at which the image was photographed. For example, as shown in FIG. 3, the memory 170 may store external object information by matching an external object image with a shooting time at which the corresponding image is photographed. The user can confirm that the courier article has been visited at 14:25 on May 25, 2017 by checking the external object information of FIG. 3 through the terminal 200. In addition, the user will know that the person has passed around the door at 15:37 on May 25, 2017, and that the person who visited the site was visited at 17:06 on May 25, 2017 .
The memory 170 may include storage devices capable of writing, reading, or erasing data, such as flash memory, hard disk, and the like.
Each component of the image storage device 100 according to an embodiment of the present invention may be a separate component, module, or device. In addition, components of the image storage device 100 may be a combination of a plurality of components, modules, or devices, and a plurality of components may be included in one component, module, or device.
In addition, some of the components of image storage device 100 according to an embodiment of the present invention may not be included in image storage device 100. For example, if a camera is present around a doorway or a doorway, the image storage device 100 may not include a camera. If the camera is not included in the image storage device 100, the image storage device 100 may communicate with the external camera to receive the shot image.
In addition, the image storage apparatus 100 according to an embodiment of the present invention may constitute an image storage system together with an external camera (not shown) and the terminal 200.
Hereinafter, an operation method of the image storage apparatus 100 according to an embodiment of the present invention will be described in detail with reference to FIG. 4 is a flowchart illustrating an operation method of an image storage apparatus according to an embodiment of the present invention.
Referring to FIGS. 2 and 4, in step S110, the motion sensor 110 detects movement of an external object. In step S120, the controller 160 activates the camera 130 to take an image when there is a detected motion.
In step S 130, the controller 160 stores the photographed image in the memory 170. The controller 160 may store the photographed image in the memory 170 by matching the photographed image with the photographed image. The controller 160 may continue to store the image of the external object until the user enters and exits.
In step S140, the acceleration sensor 120 senses the movement of the door. The acceleration sensor 120 senses the magnitude of the gate acceleration and transmits the measured value to the controller 160. In step S150, the controller 160 may determine whether or not the user enters or exits based on the measurement value transmitted from the acceleration sensor 120. [
If the controller 160 determines that the user has entered or exited, the controller 160 connects to the user terminal 200 in a wireless communication manner via the communication module 150 in step S160. For example, when a user opens a door, the communication module 150 can connect to the user terminal 200 in a Bluetooth manner. The controller 160 may connect to the user terminal 200 through the communication module 150 only when the user enters and exits, thereby minimizing power consumption due to communication.
In step S170, the controller 160 wirelessly connects to the user terminal 200, and then transmits the image stored in the memory 170. [ The controller 160 may transmit the external object information matching the shooting time and the shot image to the terminal 200 as shown in FIG. The user can confirm the visit time of the visitor and the identity of the visitor through the external object information.
The external object information transmitted to the user terminal 200 can be confirmed through an application included in the terminal. The user can access the application to check the shooting time and information on the shot image. In addition, the user can control the operation of the image storage device 100 through the application. For example, if the user goes out, the user can input the start of operation of the image storage device 100 through the application. When the user returns from the outing, the user can confirm the information of the external object that has occurred during the outgoing by using the image storage device 100.
In step S180, the controller 160 may delete the transferred external object image from the memory 170. [ Since the external object information transmitted by the controller 160 is stored in the terminal 200 of the user, the user can continuously check the external object information through the terminal 200. Accordingly, the controller 160 can manage the capacity of the memory 170 by deleting the external object image stored in the memory 170. [
Hereinafter, a method of operating the camera in step S120 will be described with reference to FIGS. 5 is a flowchart showing a camera operation method of the image storage device of FIG.
In certain circumstances, the controller 160 may not activate the camera 130 even if there is movement of an external object. Illustratively, the controller 160 may not operate the camera 130 within a predetermined time based on the previous motion detection time even if the motion is detected.
For example, when the motion sensor 110 detects motion of an external object, the controller 160 may determine whether motion has been detected within a predetermined time based on the previous motion detection time in step S121. If another motion is detected over a predetermined time based on the previous motion detection time, the controller 160 can photograph the image by operating the camera in step S122. If another motion is detected within a predetermined time based on the previous motion detection time, the controller 160 may not photograph the external object image without activating the camera 130
For example, if motion of an external object is detected again within 2 seconds after motion detection of the external object, the controller 160 may not operate the camera 130. When the motion is sensed again by the motion sensor 110 and the motion is detected again within a short time, the image storage apparatus 100 may be prevented from being photographed because the image storage apparatus 100 is likely to be the same external object.
In addition, when an image is stored by operating the camera 130 whenever motion is detected by the motion sensor 110, power consumption due to the operation of the camera 130 may increase, 170) Capacity may be insufficient. Therefore, the image storage device 100 according to the present invention can minimize the operation time of the camera 130 and reduce the image of the visitor stored redundantly, so that it can be implemented with low power and low capacity.
Hereinafter, a method for determining whether or not the user enters or exits at step S150 and a method for outputting an alarm sound will be described with reference to FIGS. 4, 6, and 7. FIG. FIG. 6 is a flowchart illustrating a method of outputting an alarm sound by determining whether or not a user enters or exiting the image storage device of FIG. 2; FIG. 7 is a view showing an example of the entrance / exit determination of FIG.
6, after the acceleration sensor 120 senses the acceleration of the door in step S140, the controller 160 may receive the measured value sensed by the acceleration sensor 120 in step S151. In steps S152 and S153, when the measured value is larger than a predetermined value, the controller 160 can determine that the user is in or out. Generally, when the door is opened or closed, the magnitude of the acceleration change value is largely measured, so that the controller 160 can determine whether or not the user enters or exits based on the magnitude of the measured value.
Illustratively, the controller 160 determines that the measured value of one of the measured values of the x-axis, y-axis, and z-axis sensed by the acceleration sensor 120 is greater than a predetermined value, can do. For example, assuming that a predetermined value is 100 as shown in FIG. 7, when the measured value for the x-axis is 10, the measured value for the y-axis is 150, and the measured value for the z- Since the measurement value for the axis is larger than the predetermined value, the controller 160 can determine that the user is in or out.
If the measured values of all the axes sensed by the acceleration sensor 120 are smaller than a predetermined value, the controller 160 can determine that the user has not entered or exited. For example, as shown in FIG. 7, when the measured value for the x-axis is 20, the measured value for the y-axis is 15, and the measured value for the z-axis is 7, the measured values of all the axes are smaller than predetermined values Even if the movement of the door is detected, the user may not judge the entrance or exit. When the door is shaken due to a simple impact occurring at the entrance door, the acceleration sensor 120 can sense a change in door door acceleration, and the controller 160 can determine that there is no access through the measured value.
If it is determined that the user has entered or exiting, the controller 160 determines whether the number of images stored in the memory 170 exceeds the set value in step S154. For example, when the set value is 0, the controller 160 may determine that the image stored in the memory 170 exists, and exceeds the set value.
The set value may be a value preset in the image storage device 100 or a value directly set by the user. The user can set the set value to a desired value so that if the number of images of the external object is small, the image of the external object may not be received. For example, when the user sets the setting value to 10 through the terminal 200, the image of the external object may not be received if the number of images of the external object stored in the memory is 10 or less.
In the method of outputting the alarm sound according to the embodiment of the present invention, step S154 may be omitted. If the step S154 is omitted, the controller 160 can output an alarm sound when it is determined that the user has entered or exited regardless of the number of stored images.
In step S155, the controller 160 may output an alarm sound through the alarm 140. [ The user can confirm that there is an external object while going out through the alarm sound. The user can set the terminal 200 so that the terminal 200 can be connected to the image storage device 100 by listening to the alarm sound.
According to the embodiment of the present invention, when the user requests transmission of an image stored in the image storage device 100 via the terminal 200, the image storage device 100 communicates with the user terminal 200 to transmit the stored image Can be transmitted.
