Abstract

[0002] With increasing public awareness of safety in recent years, people often rely on video surveillance systems to ensure that the situation at the scene is recorded in the event of an incident, leading to a growing demand for such systems.

In other words, if all camera devices are lost or malfunction, the central host will not receive image data from the camera devices, and therefore cannot perform functions such as image data synthesis, output, or streaming playback.

[0054] The embodiments of this disclosure will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar elements or method flows.
[0055] In this disclosure, when an element is referred to as a “connection,” it may mean an “electrical connection” or an “optical connection,” and when an element is referred to as a “coupled connection,” it may mean an “electrical coupling” or an “optical coupling.” “Connection” or “coupled connection” may also be used to indicate the operation or interaction between two or more elements. Unless specifically defined herein, “a” and “the” may refer to one or more in general. It will be further understood that the terms “comprising,” “including,” “having,” and similar words as used herein specify the features, regions, integers, steps, operations, elements, and / or components described herein, but do not exclude one or more other features, regions, integers, steps, operations, elements, components, and / or groups thereof described or additionally described herein.
[0056] Figure 1 A functional block diagram of a distributed photography system 100 according to some embodiments of this disclosure is shown. In some embodiments, the distributed photography system 100 includes sub-photography devices 110A-110D, a central photography device 120, and a network center 130.
[0057] Sub-photography devices 110A to 110D are used to photograph the environment (e.g., enclosed rooms, open spaces, or specific objects such as safes or works of art) to generate sub-image data DATA1 to DATA4 respectively. In some embodiments, sub-photography devices 110A to 110D can be implemented by a mobile photography device, a fixed photography device (e.g., a monitor), other devices with photography functions, or a combination thereof.
[0058] In some embodiments, sub-camera devices 110A to 110D are coupled to network center 130 via multiple network cables to transmit sub-image data DATA1 to DATA4 to central camera device 120 via network center 130, and receive operating power PW from power source (not shown) via network center 130. Since network cables have the function of transmitting data and power, by using network cables to connect sub-camera devices 110A to 110D and network center 130 (and central camera device 120, which will be described below), the number of wires in the distributed camera system 100 can be reduced, thereby simplifying the wiring configuration of the distributed camera system 100.
[0059] It should be noted that the number of sub-photography devices and sub-photography data in this disclosure is merely illustrative and not intended to limit the scope of this disclosure. Other numbers of sub-photography devices and sub-photography data are within the scope of this disclosure. In some embodiments, the distributed photography system 100 includes more than four sub-photography devices. In some embodiments, the distributed photography system 100 includes fewer than four sub-photography devices.
[0060] The central imaging device 120 is coupled to the network center 130 via a network cable. It receives sub-image data DATA1 to DATA4 from the sub-imaging devices 110A to 110D via the network center 130, and receives operating power PW from a power source (not shown) via the network center 130. In some embodiments, the central imaging device 120 transmits setting commands CT to the sub-imaging devices 110A to 110D to adjust the imaging parameters (e.g., resolution, frame rate, exposure, etc.) of the sub-imaging devices 110A to 110D.
[0061] In some embodiments, the central camera device 120 is also used to capture images of the environment to generate central image data DATA_C (shown in...). Figure 2 In other words, compared to the central host of a traditional distributed photography system, the central photography device 120 of the distributed photography system 100 provided in this disclosure, in addition to having the same function of receiving sub-image data DATA1 to DATA4 from sub-photography devices 110A to 110D, also has the function of photographing the environment.
[0062] In some embodiments, the central imaging device 120 is further coupled to the server 150 to, in response to receiving the trigger signal TRI, load the data according to the sub-image data DATA1-DATA4 and the central image data DATA_C (shown in...). Figure 2 The generated streaming video data ST and streaming video STV are uploaded to server 150. Regarding the central camera device 120, based on the sub-image data DATA1~DATA4 and the central image data DATA_C (shown in…),… Figure 2 For details on generating streaming video data (ST) and streaming video (STV), please see the following paragraphs.
[0063] Network center 130 is coupled to sub-camera devices 110A-110D and central camera device 120 to provide the transmission of sub-image data DATA1-DATA4 and setting commands CT between sub-camera devices 110A-110D and central camera device 120. In an embodiment not shown, network center 130 is coupled to a power source to provide operating power PW for sub-camera devices 110A-110D and central camera device 120.
[0064] In some embodiments, the distributed photography system 100 further includes a computer interface 140. The computer interface 140 is coupled to a network center 130 via a network cable to receive operating power PW and transmit trigger signals TRI to the central photography device 120 via the network center 130. In some embodiments, the computer interface 140 may be implemented via an interactive webpage, application software, other similar methods, or a combination thereof.
[0065] In some embodiments, the sub-camera devices 110A-110D, the central camera device 120, the network center 130, and the computer interface 140 are located in the same network domain so as to transmit sub-image data DATA1-DATA4, setting command CT, and trigger signal TRI to each other.
[0066] For details on the internal structure and operation of the central camera unit 120, please refer to [link / reference]. Figure 2 . Figure 2 A functional block diagram of a central camera device 120 according to some embodiments of this disclosure is shown.
[0067] In some embodiments, the central imaging device 120 includes an imaging unit 121, a network unit 122, a processing unit 123, a storage unit 124, and a connection unit 125. The imaging unit 121 is coupled to the processing unit 123 to capture images of the environment to generate central image data DATA_C.
[0068] Network unit 122 is coupled to network center 130 and processing unit 123 to provide a connection (e.g., via network cable) between central imaging device 120 and network center 130, thereby assisting central imaging device 120 in receiving sub-image data DATA1 to DATA4 and trigger signal TRI.
[0069] Processing unit 123 is coupled to imaging unit 121, network unit 122, storage unit 124, and connection unit 125, and is used to receive central image data DATA_C from imaging unit 121 and sub-image data DATA1 to DATA4 and trigger signal TRI from network center 130 via network unit 122. In some embodiments, processing unit 123 is used to perform an image synchronization procedure on central image data DATA_C and sub-image data DATA1 to DATA4 to generate streaming image data ST.
[0070] In some embodiments, the central image data DATA_C and the sub-image data DATA1 to DATA4 each contain multiple pieces of time information (used to record the time when the data was collected) and multiple pieces of image information corresponding to the multiple pieces of time information (used to record the image presented by the data). In the image synchronization procedure, firstly, the processing unit 123 analyzes the time information and image information of the central image data DATA_C and the sub-image data DATA1 to DATA4.
[0071] Next, the processing unit 123 selects each frame information corresponding to each time information from the sub-image data DATA1 to DATA4 based on each time information of the central image data DATA_C. Finally, the processing unit 123 combines the central image data DATA_C and the selected frame information of the sub-image data DATA1 to DATA4 into streaming image data ST, and outputs it to the server 150 (for example, for streaming playback).
[0072] by Figure 3 For example, Figure 3 A schematic diagram of central image data DATA_C and sub-image data DATA1 to DATA4 according to some embodiments of this disclosure is shown. The processing unit 123 can combine the image information corresponding to time T1 into streaming image data ST and output it to the server 150 for the central image data DATA_C and sub-image data DATA1 to DATA4; combine the image information corresponding to time T2 into another streaming image data ST and output it to the server 150; then combine the image information corresponding to time T3 into yet another streaming image data ST and output it to the server 150, and so on.
[0073] Through the aforementioned image synchronization procedure, the processing unit 123 can generate continuous streaming image data ST that includes images captured by the central camera device 120 and the sub-camera devices 110A to 110D. Furthermore, since each stream of image data ST combines frame information corresponding to the same time, it can improve the problem of image asynchrony caused by data transmission delays due to lines or internal circuits between the camera devices, thereby ensuring that the frames of multiple camera devices in the output streaming image data ST are synchronized.
[0074] In some embodiments, the image synchronization process is continuous. In other words, the processing unit 123 continuously receives central image data DATA_C and sub-image data DATA1 to DATA4, and continuously generates and outputs streaming image data ST to the server 150 for streaming playback.
[0075] Please refer to this again. Figure 2Storage unit 124 is coupled to processing unit 123. In some embodiments, in response to receiving a trigger signal TRI, processing unit 123 generates a streaming video STV based on the output streaming video data ST (e.g., acquiring a specified time period), and transmits the streaming video STV to storage unit 124 and server 150 to store the streaming video STV corresponding to the specified time period (e.g., 5 minutes) inside the central camera device 120 (i.e., via storage unit 124) or outside the system (i.e., via server 150). In some embodiments, storage unit 124 may be implemented by dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), other elements with storage functions, or combinations thereof.
[0076] The connection unit 125 is coupled between the processing unit 123 and the server 150 to provide a connection between the central camera device 120 and the server 150, thereby transmitting the streaming video data ST and streaming video STV from the central camera device 120 to an external system for streaming playback or storage of the video.
[0077] In some embodiments, the central camera device 120 further includes a trigger unit 126 coupled to the processing unit 123 for generating a trigger signal TRI to the processing unit 123 under specified conditions, so that the central camera device 120 manually or automatically records streaming video data ST for a specific time period. In some embodiments, the trigger unit 126 may be implemented by a button, a collision sensor, an infrared sensor, a Bluetooth signal receiver, other sensing elements, or a combination thereof.
[0078] For example, if the trigger unit 126 is implemented by a button, when the trigger unit 126 detects a trigger action (e.g., pressing a button), the trigger unit 126 generates a trigger signal TRI to the processing unit 123, and the processing unit 123 acquires the streaming video data ST for a specified time period (e.g., 5 minutes) after receiving the trigger signal TRI as a streaming video STV.
[0079] In another example, if the triggering unit 126 is implemented by a collision sensor, when the triggering unit 126 detects a triggering action (e.g., the central camera device 120 is hit), the triggering unit 126 generates a trigger signal TRI to the processing unit 123, and the processing unit 123 acquires the streaming video data ST for a specified time period (e.g., 5 minutes) after receiving the trigger signal TRI as a streaming video STV.
[0080] In some embodiments, the trigger signal TRI can be used not only to instruct the processing unit 123 to generate a streaming video STV based on the output streaming video data ST, but also to instruct the processing unit 123 to upload the streaming video data ST and the streaming video STV to the server 150 for streaming playback of the streaming video data ST and storing the streaming video STV in an external system.
[0081] Figure 4 A flowchart of a distributed photography method 400 according to some embodiments of this disclosure is shown. In some embodiments, the distributed photography method 400 includes steps S410, S420, S430, S440, S450, S460, and S470.
[0082] The distributed photography method 400 begins with step S410. In step S410, at least one sub-image data (e.g., sub-image data DATA1 to DATA4) and a central image data (e.g., central image data DATA_C) are generated based on the environment by at least one sub-photography device (e.g., sub-photography devices 110A to 110D) and a central photography device (e.g., central photography device 120). Next, step S420 is executed.
[0083] In step S420, at least one sub-image data is received from at least one sub-photographic device via the processing unit (e.g., processing unit 123) of the central imaging device. Then, step S430 is executed.
[0084] In step S430, the processing unit performs an image synchronization procedure on the central image data and at least one sub-image data to generate streaming image data (e.g., streaming image data ST). Then, step S440 is executed.
[0085] In step S440, the processing unit determines whether a trigger signal (e.g., trigger signal TRI) has been received. If the processing unit determines that a trigger signal has been received, step S450 is executed; if the processing unit determines that no trigger signal has been received, step S410 is executed again.
[0086] In step S450, a portion of the streaming video data corresponding to a specified time period is obtained by the processing unit to generate a streaming video (e.g., streaming video STV), and the streaming video is stored in the storage unit (e.g., storage unit 124) of the central camera device.
[0087] In step S460, the processing unit determines whether it has received an instruction to upload the streaming video to the server (e.g., server 150). If the processing unit determines that the instruction has been received, it proceeds to step S470; if the processing unit determines that the instruction has not been received, it re-executes step S410.
[0088] In step S470, the streaming video data and streaming video are uploaded to the server via the connection unit of the central camera device (e.g., connection unit 125). After completing step S470, step S410 is executed again.
[0089] It should be noted that the number and order of steps in the distributed photography method 400 of this disclosure are merely examples and are not intended to limit this disclosure. The number and order of other steps are within the scope of this disclosure. In some embodiments, step S460 may be omitted, and step S470 may continue to be executed after step S450.
[0090] The central camera device, distributed camera system, and distributed camera method disclosed herein enable the central device in the distributed camera system to not only integrate images from other cameras but also capture images itself. Therefore, even if all the sub-cameras in the distributed camera system malfunction and fail to produce images, the central camera device can still capture images and generate streaming video.
[0091] The above are merely preferred embodiments of this disclosure. Various modifications and equivalent changes can be made to the structure of this disclosure without departing from its scope or concept. In summary, all modifications and equivalent changes made to this disclosure within the scope of the following claims are within the scope of this disclosure.
