Description

  The present invention relates to video processing control of a video processing system having video acquisition means for acquiring a subject video and output control means for outputting the subject video to devices of a plurality of logged-in viewers.

  Recently, the shortage of doctors is becoming a serious problem in the depopulated regions. In addition, there are no cases of medical mistakes that cause patients to worsen their medical condition due to inappropriate treatment by doctors. In addition, there is a demand to develop medical technologies in less developed countries by showing doctors in less advanced countries the state of advanced medical care conducted in advanced medical countries in order to rectify international medical disparities.

  Therefore, it can be said that it is meaningful to distribute the same video information to a remote viewer (doctor or family member).

  However, on the other hand, there is a tendency that the right to protect privacy such as protection of personal information is also regarded as important, and there is a case where processing such as applying a mosaic without distributing unnecessary video may be necessary.

  Thus, in the present age where complicated situations are intertwined, a system that realizes them simultaneously has been demanded.

  Patent Document 1 proposes a technique that enables privacy protection of a subject by selecting and executing appropriate video processing according to the subject.

Patent Document 2 proposes a technique for providing an image in which different areas are masked for each user.

  However, in these conventional techniques, the video processing method is fixed depending on the type of the viewer or the subject, and the following problems have occurred.

  For example, when considering remote medical care, when a doctor confirms a patient's condition, it may be for therapeutic purposes or may only want to confirm the patient's condition. While the doctor is performing treatment, it may be desirable to hide the patient's video from other viewers for privacy reasons. When trying to realize this with the prior art, there is a problem that it is not possible to satisfy the request of hiding the patient's video from other viewers only while the doctor is performing treatment.

  The present invention has been made to solve the above problems, and an object of the present invention is to dynamically perform video processing according to the relationship between viewers in a video processing system that is browsed by an unspecified number of people. It is to provide a mechanism that can determine the method.

  The present invention relates to a video processing system having video acquisition means for acquiring a subject video and output control means for outputting the subject video to devices of a plurality of logged-in viewers. Each time the means and the logged-in viewer change, the relationship between the viewers is determined based on the information of the viewer stored in the storage means, and the video processing method for each viewer is determined. And determining means.

  According to the present invention, in a video processing system that is browsed by an unspecified number of people, a video processing method can be dynamically determined according to the type of viewer or the relationship between subjects.

  Therefore, appropriate video processing is selected and executed according to the relationship between the viewers so that the request of hiding the patient's video from other viewers can be satisfied only while the doctor is performing treatment. By doing so, effects such as protection of personal information of the subject and flexible video processing can be achieved.

[Description of characters in the embodiment]
In this embodiment, a plurality of patients (patient ID 20000, patient ID 30000) are used as examples of subjects.

  The patient holds a wristband-type subject attribute transmission device 401 on the wrist, and subject attribute information (FIG. 4 to be described later) such as “position information” and “subject ID” is stored in the “subject”. It can be dynamically transmitted to the attribute information DB 122 ”.

  In this embodiment, the patient's family ID 100001, doctor ID 000001, and doctor ID 000002 are used as examples of the viewer.

  Note that the administrator registers the information of the viewer in advance in the viewer information (FIG. 3 to be described later) together with the viewer ID. Further, it is assumed that “subject attribute information (FIG. 4 to be described later)” is registered in advance as the subject information together with the subject ID.

  FIG. 3 is a data configuration diagram illustrating the configuration of the viewer information DB 121 illustrated in FIG.

  As shown in FIG. 3, the browser information DB 121 stores a browser ID, a password, a browser rank, an exclusive right, and a login flag.

  The viewer rank indicates a viewer's priority of video browsing, and is used in the individual video processing method determination process (S24 in FIG. 7 described later). Based on that between the viewers, the video processing is performed. It will change the way. In addition, this viewer rank shall show a high rank, so that a numerical value is low.

  The exclusive right indicates that zero or more subject IDs are stored and the subject corresponding to the subject ID can be viewed exclusively. In the individual video processing method determination process (S24 in FIG. 7), the video processing method is changed based on this exclusive right.

  The login flag holds information “1” if the target viewer is currently logged in, and “0” otherwise. The login flag is dynamically updated by the viewer information acquisition unit 101 every time the viewer logs in or logs out.

  FIG. 4 is a data configuration diagram illustrating the configuration of the subject attribute information DB 122 illustrated in FIG.

  As shown in FIG. 4, the subject attribute information DB 122 stores a subject ID, an X coordinate, a Y coordinate, and a processing flag. Note that information in the subject attribute information DB 122 is continuously updated by the subject attribute acquisition unit 104.

  The X coordinate and Y coordinate hold the coordinates of the center where the target subject is currently in the screen. This coordinate is a value calculated and obtained by a known technique based on the position information of the subject received by the subject attribute receiving unit 400, and is used when determining an image processing area in the video. It is.

  FIG. 5 is a data configuration diagram illustrating a configuration of the video processing method storage memory 105a illustrated in FIG.

  As shown in FIG. 5, the video processing method storage memory 105a stores the individual video processing methods corresponding to the viewer ID and the number of subjects. In this individual video processing method, a subject ID and a processing method are stored, and are determined in an individual video processing method determination process (S23 in FIG. 7 described later).

  Hereinafter, the control processing operation executed by the video processing apparatus 100 will be described with reference to the flowcharts of FIGS.

  FIG. 6 is a flowchart illustrating an example of a first control processing procedure according to the present invention, and corresponds to a control processing operation executed by the video processing apparatus 100. Note that the processing in this flowchart is executed by each functional unit shown in FIG. That is, it is realized by the CPU 142 of the video processing apparatus 100 shown in FIG. 1 loading and executing a program stored in the HD 145 on the RAM 143. In the figure, S11 to S17 indicate steps.

  First, the CPU 142 of the video processing apparatus 100 starts the process of this flowchart when the start button is pressed (when the start instruction of this control process is given).

  First, in step S11, the CPU 142 determines whether or not the end button has been pressed (whether an instruction to end the present control process has been issued), and determines that the end button has not been pressed (not instructed to end the present control process). When it determines, CPU142 advances a process to step S12.

  In step S12, the CPU 142 acquires information from the viewer information DB 121 (FIG. 3), and determines whether or not the login viewer has changed.

  If it is determined in step S12 that the login viewer has changed, in step S13, the CPU 142 executes a video processing method update process, and the process proceeds to step S14. Details of this video processing method update processing are shown in FIG.

  On the other hand, if it is determined in step S12 that the login viewer has not changed, the CPU 142 proceeds to step S14 as it is.

  In step S14, the CPU 142 acquires subject attribute information (FIG. 4) from the subject attribute information DB 122.

  Next, in step S15, the CPU 142 determines whether or not there is a non-displayed viewer. If it is determined that there is a non-displayed viewer, the process proceeds to step S16.

  In step S16, the video processing execution unit 105 executes video processing based on the individual video processing methods (“no processing”, “video processing 1”, “video processing 2”) stored in the individual video processing method storage memory 150a. In step S17, the video output unit 106 outputs the video processed by the video processing execution unit 105 to the corresponding viewer terminal 200. Upon receiving this, the viewer terminal 200 controls the display of the processed video on the display device.

  When the process of step S17 ends, the CPU 142 returns the process to step S15 and proceeds to the process for the next non-displayed viewer.

  In step S15, if the CPU 142 determines that there is no undisplayed viewer, the process returns to step S11.

  If the CPU 142 determines in step S11 that the end button has been pressed (the end instruction for this control process has been issued), the process of this flowchart ends.

  Hereinafter, with reference to FIG. 7, the video processing method update process shown in step S13 of FIG. 6 will be described.

  FIG. 7 is a flowchart showing an example of the second control processing procedure in the present invention, and corresponds to the video processing method update processing shown in step S13 of FIG. Note that the processing in this flowchart is executed by each functional unit shown in FIG. That is, it is realized by the CPU 142 of the video processing apparatus 100 shown in FIG. 1 loading and executing a program stored in the HD 145 on the RAM 143. In the figure, S20 to S25 indicate each step.

  First, in step S20, the CPU 142 clears the video processing method storage memory 105a (clears individual viewers' individual video processing methods), and proceeds to step S21.

  In step S21, the CPU 142 determines whether there is an unprocessed viewer. In this determination, a viewer who is logged in and who does not have the individual video processing method set in the video processing method storage memory 105a is determined as an unprocessed viewer.

  If it is determined in step S21 that there is an unprocessed viewer, the CPU 142 sets one of the unprocessed viewers as the target viewer, proceeds to step S22, and subjects the subject attribute information DB 122 (FIG. All the processing flag information of the subject stored in 4) is set to “0”.

  Next, in step S23, the CPU 142 determines whether or not there is an unprocessed subject (subject with a processing flag of “0”), and determines that there is an unprocessed subject (subject with a processing flag of “0”). In this case, any unprocessed subject is set as the target subject, and the process proceeds to step S24.

  In step S24, the CPU 142 executes an individual video processing method determination process by the individual video processing method determination unit 102 for the target subject, and proceeds to step S25. Details of the individual image processing method determination processing are shown in FIG.

  Next, in step S25, the processing flag information of the target subject stored in the CPU 142 and subject attribute information DB 122 (FIG. 4) is set to “1”, the process returns to step S23, and the next unprocessed subject is processed. Transition to processing.

  In step S23, if the CPU 142 determines that there is no unprocessed subject (subject whose processing flag is “0”), the process proceeds to step S21, and the process proceeds to processing for the next unprocessed viewer.

  If the CPU 142 determines in step S21 that there is no unprocessed viewer, the process of this flowchart ends. Note that “video processing 1” and “video processing 2” are both processing methods for processing a subject video into an unrecognizable video, and may be the same video processing.

  Hereinafter, with reference to FIGS. 8 to 12, the individual image processing method determination process shown in step S <b> 24 of FIG. 7 will be described. The individual video processing method determination process is for determining a video processing method for a certain subject by a certain viewer.

  FIG. 8 is a flowchart showing an example of a third control processing procedure in the present invention, and corresponds to the individual video processing method determination processing shown in step S24 of FIG. Note that the processing in this flowchart is executed by each functional unit shown in FIG. That is, it is realized by the CPU 142 of the video processing apparatus 100 shown in FIG. 1 loading and executing a program stored in the HD 145 on the RAM 143. In the figure, S140 to S149 indicate steps.

  9 to 12 are schematic diagrams for explaining the video of the target subject displayed on the viewer terminal 200 of the target viewer.

  First, in step S140 of FIG. 8, the individual video processing method determination unit 102 determines whether there is a viewer other than the target viewer. If it is determined that there is no viewer other than the target viewer, the process proceeds to step S149. Proceed with the process.

  In step S149, the individual video processing method determination unit 102 determines “no processing” as the individual video processing method for the target subject of the target viewer, stores it in the individual video processing method storage memory 105a, and ends the processing of this flowchart. To do. In this case, an image of the target subject that has not been processed is displayed on the viewer terminal 200 of the target viewer as shown in 901 and 902 of FIG. 9 described later.

  On the other hand, if the individual image processing method determination unit 102 determines in step S140 that there is a viewer other than the target viewer, the process proceeds to step S141.

  In step S141, the individual video processing method determination unit 102 acquires the viewer rank of the target viewer stored in the viewer information DB 121 (FIG. 4).

  Next, in step S142, the individual video processing method determination unit 102 acquires all the viewer ranks of other viewers stored in the viewer information DB 121 (FIG. 3).

  Next, in step S143, the individual video processing method determination unit 102 determines whether or not there are other viewers exceeding the viewer rank of the target viewer, and other viewers exceeding the viewer rank of the target viewer. If it is determined that there is, the process proceeds to step S147.

  In step S147, the individual video processing method determination unit 102 determines “video processing 1” as the individual video processing method for the target subject of the target viewer, and stores it in the individual video processing method storage memory 105a. And the process of this flowchart is complete | finished. In this case, the processed video image of the target subject as shown in 1001 and 1002 in FIG.

  On the other hand, if the individual image processing method determination unit 102 determines in step S143 that there is no other viewer exceeding the viewer rank of the target viewer, the process proceeds to step S144.

  In step S144, the individual video processing method determination unit 102 searches for and acquires a viewer who has the exclusive right of the target subject from the viewer information DB 121 (FIG. 3) and the subject attribute information DB 122 (FIG. 4).

  Next, in step S145, the individual video processing method determination unit 102 determines whether or not a viewer having the exclusive right of the target subject is logged in. If it is determined that the viewer is not logged in, the individual video processing method determination unit 102 determines in step S149. The individual video processing method for the target subject of the target viewer is determined as “no processing”, and is stored in the individual video processing method storage memory 105a, and the processing of this flowchart ends.

  On the other hand, if the individual video processing method determination unit 102 determines in step S145 that the viewer having the exclusive right of the target subject is logged in, the process proceeds to step S146.

  In step S146, the individual video processing method determination unit 102 refers to the viewer information DB 121 (FIG. 3) to determine whether or not the target viewer has the exclusive right of the target subject, and has the exclusive right. In step S149, the individual image processing method for the target subject of the target viewer is determined to be “no processing”, stored in the individual video processing method storage memory 105a, and the processing of this flowchart ends.

  On the other hand, if the individual video processing method determination unit 102 determines in step S146 that the target viewer does not have the exclusive right of the target subject, in step S148, the individual video processing method for the target subject of the target viewer. Is determined to be “video processing 2”, stored in the individual video processing method storage memory 105a, and the processing of this flowchart ends. In this case, the processed video image of the target subject as shown in 1002 of FIG. 11 and 1201 of FIG. 12 will be displayed on the viewer terminal 200 of the target viewer.

  Through the above processing, video processing corresponding to the relationship between viewers can be performed. Hereinafter, a specific description will be given using a setting example of the viewer information DB 121 illustrated in FIG. 3.

  For example, it is assumed that two subjects, patient ID 20000 and patient ID 30000, are set as subjects. Then, assuming that only the patient's family ID 100001 (browser rank “2”) is in the logged-in state, the viewer distributes the video delivered to the viewer terminal 200 of the patient's family ID 100001 “No processing”. As shown in FIG.

  When the doctor ID 000001 (viewer rank “1”) is logged in, the viewer rank of the doctor ID 000001 is “1”, so the video delivered to the viewer terminal 200 of the patient family ID 100001 is “ 9 is applied to switch to the state shown in FIG. 10, and the video delivered to the viewer terminal 200 with the doctor ID 000001 changes to the state shown in FIG. As a result, only while the doctor (browser with a high browsing rank) is performing treatment, the patient's video is hidden from other viewers (browser with a low browsing rank) such as family members. It can meet the demands of protecting privacy. Thus, by selecting and executing appropriate video processing according to the relationship between viewers (viewer rank), it is possible to protect the personal information of the subject and to perform flexible video processing.

  Also, assuming that only the specialist doctor ID 000001 (browser rank “1”, exclusive right “20000”) of the patient ID 20000 as the viewer is in the logged-in state, distribution to the viewer terminal 200 of the specialist doctor ID 000001 of the patient ID 20000 at this time The image to be displayed becomes “no processing” as shown in FIG.

  After that, when the specialist doctor ID 000002 (browser rank “1”, exclusive right “30000”) of the patient ID 30000 is logged in, the specialist ID ID “000001” of the patient ID 20000 does not have the exclusive right “30000”. “Video processing 2” is applied to the video of the patient ID 30000 distributed to the browser terminal 200 of the doctor ID 000001, and the status is switched from the status 902 in FIG. 9 to the status 1102 in FIG. Note that since the specialist doctor ID 000001 of the patient ID 20000 has the exclusive right “20000”, the video of the patient ID 20000 remains “no processing” and is in the state 1101 in FIG. 11 (the state in 901 in FIG. 9).

  Furthermore, since the specialist doctor ID 000002 of the patient ID 30000 does not have the exclusive right “20000”, the video of the patient ID 20000 distributed to the viewer terminal 200 of the specialist doctor ID 000002 of the patient ID 30000 is subjected to “image processing 2”. 12 state 1201. Further, since the specialist doctor ID 000002 of the patient ID 30000 has the exclusive right “30000”, the video of the patient ID 30000 delivered to the viewer terminal 200 of the specialist doctor ID 000002 of the patient ID 30000 remains “no processing” in 1202 of FIG. It becomes a state.

  Thereby, the image of the patient can be hidden from other doctors (there is no exclusive case) only while the specialist doctor (having exclusive rights) is treating. Thus, by selecting and executing appropriate video processing according to the relationship between viewers (existence of exclusive rights), it is possible to protect the personal information of the subject and to perform flexible video processing. .

  A video processing system to which the present invention is applied is shown in FIG. In addition, the same code | symbol is attached | subjected to the same thing as FIG.

  This system tries to disclose a situation where multiple patients need medical examinations in remote areas such as remote islands where doctors need to be examined, and to disclose images being treated to multiple doctors for the purpose of medical technology development. It is assumed that there is a situation.

  By realizing such a system, the video processing method of the subject (patient) image can be dynamically determined according to the relationship between the viewers (patient and doctor, doctors, etc.), and depopulation can be achieved.
