Description

  The present invention relates to a technique that makes it possible to easily search a time position related to an arbitrary explanation location on a document from conference record data.

  Currently, an electronic board system is sometimes used for presentation of materials in meetings and presentations. The electronic board system is a system including a display device (for example, a projector or a flat display) for a computer screen and a position detection device that detects a contact position of an electronic pen, a finger, or the like with respect to the display surface. When the electronic board system is used, not only the display of slides prepared in advance, but also the input of characters, figures and other objects, and the operation input of computers and presentation software can be realized through the operation input on the display surface.

  Recently, a mechanism has been proposed in which electronic board systems at remote locations are connected to each other via a network, and the operation contents performed on one electronic board system are reflected in real time on the other electronic board system. If this mechanism is combined with a voice input / output device capable of voice communication over a long distance, it can also be used for a conference over a long distance.

  On the other hand, a video camera and a microphone are used for recording the contents of the conference. That is, the conference content is recorded by video data and audio data. This type of prior art can record both the presenter and the material being described at the same time. In other words, it is possible to record the conference as it is viewed.

  Hereinafter, an example of a conference record system according to the present invention will be described with reference to the drawings. Note that each of the embodiments described below is merely an example, and the present invention includes only a system realized by combining arbitrary functions described in this specification, and some configurations and functions described in this specification. In addition to the realized system, a system in which only a part of the configuration and functions is replaced by a known technique is also included. In addition, the function executed in the embodiment described later will be described as being realized as a program executed on a computer (computer). However, part or all of the program may be realized through hardware.

(Whole system)
FIG. 1 shows a configuration example of a conference record system. 1 includes an electronic board 101, a camera 102, a microphone 103, a computer 104, an external storage device 105, a data conversion device 106, a cursor position conversion unit 107, a video data conversion unit 108, a display device 109, and data search. The apparatus 110 is configured.

  The electronic board 101 is used not only as a conference material display device but also as an input device for the computer 104. For example, it is used for a cursor position input operation of the computer 104 and an operation input for display. For example, it is used for moving the display position of the cursor and emphasizing explanation parts.

  In the case of FIG. 1, the electronic board 101 represents the example which uses a flat display for a display apparatus. In addition, a configuration in which the display device is a projector is also possible. When a projector is used, a projection screen is used for the electronic board 101.

  In the case of this embodiment, a polarizing film that passes only a specific polarization component is disposed on the display surface (detection surface). As will be described later, the polarizing film is used to cut out only the presenter from an image obtained by imaging the display surface.

  A known position detection technique is used for detecting the operation position of the presenter with respect to the display surface (detection surface). For example, a pressure sensitive method, an electromagnetic method, a laser method, an ultrasonic method, an infrared method, a resistance film method, a capacitance method, or the like is used. Due to the difference in position detection method, the device configuration and structure of the electronic board are different. In the case of this embodiment, it is assumed that the arithmetic unit 1011 that calculates the operation position of a finger, an electronic pen, etc. as coordinate data on the display surface is mounted on the electronic board 101. In the case of this embodiment, the coordinate origin of the electronic board 101 is the upper left corner of the display surface. The X axis is the horizontal direction of the electronic board 101, and the Y axis is the vertical direction of the electronic board 101.

  The computer 104 is connected to the electronic board 101, outputs data (image data) to the electronic board 101, outputs a drawing object (object data) generated based on the analysis of the coordinate data sequence to the electronic board 101, It controls the execution of the processing operation based on the data analysis of the coordinate data string and the output of the processing result to the electronic board 101. The computer 104 is connected to an external storage device 105, and external storage such as material data displayed on the electronic board 101 during the meeting, material data displayed on the electronic board 101 during the meeting, resolution information of the electronic board 101, and the like. Controls recording to the device 105. The connection between the computer 104 and the electronic board 101 may be wired or wireless.

  The external storage device 105 is assumed to be a file server connected via a network. However, when a small system configuration is sufficient, a hard disk device built in the computer 104 or a hard disk device directly attached may be used.

  The camera 102 is used for acquiring the image of the explainer and acquiring the position of the explainer. In the case of this embodiment, the camera 102 is installed at a position where only the entire display surface of the electronic board 101 displaying the material can be imaged. That is, the camera 102 is installed at a position where the outside of the display surface of the electronic board 101 is not included in the imaging target. Video data captured by the camera 102 is stored as file data in the external storage device 105.

  In order to extract only the presenter from the photographed image, the camera 102 is equipped with a polarizing film that passes only a polarized component in a direction different from that of the polarizing film mounted on the electronic board 101 side. By attaching the polarizing film, the display image on the electronic board 101 is captured in black. On the other hand, the presenter who enters the range of the display surface of the electronic board 101 is photographed as a color image. For this reason, by separating the black image region, only the explainer image can be extracted from the captured image. In order to extract the image of the presenter, it is desirable for the presenter to wear clothing other than black.

  The microphone 103 is used to acquire the voice of the presenter and the voice of the conference attendee. For this reason, the microphone 103 is installed at a position where it is easy to acquire both the voice of the presenter and the voice of the conference attendee. The audio data during the conference (from the start to the end of the conference) acquired by the microphone 103 is stored as file data in the external storage device 105.

  The data conversion device 106 is connected to the external storage device 105 and executes data conversion processing necessary for data retrieval and data conversion processing necessary for reproduction of conference record data. In the case of FIG. 1, the data conversion device 106 is illustrated as a separate device of the computer 104, but the data conversion device 106 may be one of application software executed on the computer 104. The data converter 106 includes a cursor position converter 107 and a video data converter 108. In this embodiment, the data conversion device 106 is assumed to be realized as application software executed on a computer different from the computer 104.

  The cursor position conversion unit 107 executes a process of converting the coordinates of the display surface coordinate system of the electronic board 101 into the coordinates of the document coordinate system in order to enable the data search device 110 to search for an explanation location in the document. In the document coordinate system, the upper left corner of the document is the coordinate origin, the horizontal direction in the screen is the x axis, and the vertical direction is the y axis. The coordinate data after the conversion process is stored in the external storage device 105.

  The video data conversion unit 108 is acquired from the camera 102 in order to display the document displayed on the electronic board 101 and the explainer in an overlapping state when displaying the contents of the minutes data on the display device 109. The conversion process of the video data of the explainer is executed.

  The display device 109 acquires the data converted by the data conversion device 106 from the external storage device 105 and reproduces the content of the conference. The display device 109 may be an image display device, and does not necessarily have the same display size as the electronic board 101. The display device 109 may be a display unit of the computer 104 or the electronic board 101.

  The data search device 110 executes a search for one or a plurality of minutes data, and executes a reproduction process for the corresponding part based on the search result. Here, the data search device 110 searches the material data and cursor position data stored in the external storage device 105. The data search device 110 displays a search condition input GUI on the display device 109. In addition, the data search device 110 displays position information (time stamp) on the time axis of the minutes data whose cursor position matches or is included in the specific range of the material input as the search condition on the display device 109 as a search result. To do. In addition, the data search device 110 reproduces conference record data (material data, video data captured by the camera 102, audio data acquired by the microphone 103) from a position on the time axis selected from the search result screen. The reproduced image is displayed on the display device 109.

(Meeting record data save operation)
FIG. 2 shows a procedure for storing the minutes data. This processing operation is realized through an application program executed by the computer 104. FIG. 2 also includes preprocessing before the start of the conference.

  Prior to the start of the conference, the computer 104 stores the resolution information of the electronic board 101 (step 201). FIG. 3 shows an example data structure of resolution information. The resolution information includes a resolution 301 in the X-axis direction and a resolution 302 in the Y-axis direction. In addition, the computer 104 stores material data used in the conference (step 202). The computer 104 acquires size information of each material when storing the material data. Material numbers used in the conference are sequentially numbered in the reading order (step 203). In this embodiment, materials are managed in units of pages, and a material number is assigned to each page. The material size information and the material number are stored in the external storage device 105 as material management data (step 204). FIG. 4 shows an example of the structure of management data stored in the external storage device 105. The management data includes a material number 401, a material name 402, and material size information (size information 403 in the x-axis direction and size information 404 in the y-axis direction). With this management data, the correspondence between the material name, material number, and material size is known. Note that the execution order of step 201 and step 202 may be switched.

  Next, processing operations executed by the computer 104 after the start of the conference will be described. When the start of the meeting is detected, the computer 104 determines whether or not the meeting has ended (step 205). The computer 104 detects the start of the conference through the occurrence of voice input and the input of a start operation by the presenter or operator. In addition, the computer 104 detects the end of the conference through continuation of the silent time for a certain period or more and input of an end operation by the operator.

  While it is determined that the meeting is in progress (while a negative result is obtained in step 205), the computer 104 displays the time from the start of the meeting, the material number 401 of the material displayed on the electronic board 101, and the electronic board 101. The position of the material displayed above (displayed material position) (position on the electronic board coordinate with respect to the material origin coordinate) and the cursor position on the electronic board 101 are set as a set, and recorded in the external storage device 105 as conference record data. Save (step 206). Note that the camera 102 and the microphone 103 operate simultaneously with the start of the conference, and the video data acquired from the camera 102 and the audio data acquired from the microphone 103 are also stored in the external storage device 105.

  During the meeting, the presenter moves the cursor to an explanation location on the document or emphasizes the display content through an operation input on the display surface (detection surface) of the electronic board 101. In addition, the presenter also performs operation inputs such as enlargement and reduction of a part of the document through the same operation.

  Data storage is executed at regular time intervals, when the cursor position changes (when moving), or when the display material is changed. The change of the display material includes not only switching to a different material but also enlargement / reduction of display contents within the same material, movement of a display location, and the like. Note that the output value of the built-in timer of the computer 104 is used as the elapsed time from the start of the conference. The fixed time may be fixed or variable by an operator's operation. Further, the computer 104 monitors the cursor position displayed on the display surface of the electronic board 101, and determines whether or not the cursor position has changed (moved) depending on whether or not the cursor position has changed more than a threshold value within the determination period. To do.

  FIG. 5 shows an example of the structure of conference record data stored in step 206. In the case of this embodiment, the minutes data includes the time 501 from the start of the meeting, the display material number 502, the display material position (upper left X coordinate) 503, the display material position (upper left Y coordinate) 504, the material enlargement ratio 505, and the display cursor. It consists of a position (x coordinate) 506 and a display cursor position (y coordinate) 507. Here, the display material positions 503 and 504 and the display cursor positions 506 and 507 are given by the coordinate system of the electronic board 101.

  6 and 7 show the relationship between the size of the material assumed in this embodiment and the size of the electronic board. FIG. 6 shows a case where the material size 602 is larger than the electronic board size 601. This case occurs, for example, when the magnification factor of the material is greater than 1. As shown in this example, in the case of FIG. 6, the display material positions 503 and 504 both take negative values. FIG. 7 shows a case where the material size 702 is smaller than the electronic board size 701. This case occurs, for example, when the magnification factor of the material is smaller than 1. However, here, the magnification is 1 when the display size of the document matches the display size of the electronic board 101. In the case of FIG. 7, the display cursor positions 506 and 507 both take positive values.

  When the conference ends (when an affirmative result is obtained in step 205), the computer 104 ends the processing process related to storage.

(Cursor position data conversion operation)
Next, a data conversion operation executed in the cursor position conversion unit 107 of the data conversion device 106 for searching and reproducing the minutes data will be described. This conversion operation only needs to be completed before the search for conference minutes data is started. Therefore, it may be executed in parallel with the storage of the minutes data.

  This conversion operation is executed as a pre-process for enabling a search specifying a specific part of the material explained by the presenter. Specifically, an operation of converting the coordinate value of the cursor position given in the coordinate system of the electronic board 101 into the coordinate value of the coordinate system of the material is executed. If the cursor position can be expressed in the coordinate system of the document, it is possible to specify the location that the explainer explained during the meeting, and it is possible to perform a search specifying the document and its explanation location in a later search Because.

  FIG. 8 shows a cursor position data conversion operation by the cursor position conversion unit 107. However, when the size of the material matches the size of the electronic board, and the coordinate value on the material matches the coordinate value on the electronic board, this conversion processing is unnecessary.

  First, the cursor position conversion unit 107 acquires resolution information (FIG. 3) of the electronic board from the external storage device 105 (step 801).

  Next, the cursor position conversion unit 107 acquires the material size data (FIG. 4) and the minutes data (FIG. 5) from the external storage device 105 (step 802).

  After that, the cursor position conversion unit 107 determines whether or not there is conference data that is not a data conversion processing target (step 803). If there is unprocessed conference record data, the data converter 106 reads one row of conference record data (step 804).

  Next, the cursor position conversion unit 107 acquires a display material position and an enlargement ratio from the read conference record data (step 805). Further, the cursor position conversion unit 107 acquires the cursor position on the electronic board 101 from the read conference record data (step 806).

  When these data are acquired, the cursor position conversion unit 107 converts the cursor position on the electronic board into the cursor position on the document based on the calculation formula shown in FIG. 9 (step 807). Incidentally, 901 is an X coordinate conversion formula, and 902 is a Y coordinate conversion formula.

  Next, the cursor position conversion unit 107 determines whether or not the calculated cursor position on the material is outside the material (step 808). If it is in the document (in the case of a negative result in step 808), the cursor position conversion unit 107 returns to step 803. On the other hand, if it is outside the document (in the case of an affirmative result in step 808), the cursor position conversion unit 107 discards the minutes data and returns to step 803 (step 809). Here, whether or not the calculated cursor position is on the material is executed by comparison with material size data (FIG. 4) acquired before the meeting.

  By executing this conversion operation for all conference data recorded from the start to the end of the conference, the cursor position conversion unit 107 can obtain the cursor position on the material at each time.

  When the conversion process is completed for all minutes, the cursor position conversion unit 107 gives the time from the start of the meeting and the material number of the displayed material to the information on the cursor position that has not been discarded, The data is stored in the external storage device 105 (step 810). FIG. 10 shows the structure of data stored in the external storage device 105 as the cursor position on the material. The cursor position data on the material includes a time 1001 from the start of the conference, a display material number 1002, a cursor position on the material (X coordinate) 1003, and a cursor position on the material (Y coordinate).

(Video data conversion operation)
Next, a data conversion operation executed in the video data converter 108 of the data converter 106 will be described. That is, the conversion operation of video data captured by the camera 102 will be described. This conversion operation may be completed before the search for the minutes data is started. Therefore, it may be executed in parallel with the imaging of the camera 102. This conversion operation is executed for the purpose of extracting only the explainer image from the video data in order to display the video of the explainer captured by the camera 102 in an overlapping manner with the material.

  As described above, polarizing films having different polarization components that pass through are mounted on the display surfaces of the camera 102 and the electronic board 101, respectively. For this reason, the area of the display surface of the electronic board 101 in the captured image of the camera 102 is a black screen. The shooting range of the camera 102 matches the display surface size of the electronic board 101. For this reason, when the presenter stands in front of the electronic board 101, the presenter image is displayed as an image having a black background.

  FIG. 11 shows the video data conversion operation by the video data converter 108.

  First, the video data converter 108 acquires video data shot by the camera 102 from the external storage device 105 (step 1101).

  Next, the video data converter 108 converts the acquired video data into time unit image data (step 1102).

  Next, the video data converter 108 determines whether there is unprocessed image data (step 1103). When there is unprocessed image data (when a positive result is obtained in step 1103), the video data conversion unit 108 reads image data with the next time information attached to the previously processed image data. (Step 1104).

  Subsequently, the video data conversion unit 108 sets black, which is the background color of the read image data, as a transparent color (step 1105). However, if the image data at this time is directly overlapped with the material, it becomes impossible to see the material of the portion overlapping with the presenter.

  Therefore, the video data converter 108 sets a color other than the background color to a semi-transparent color (for example, about 50%) (step 1106). By this setting, when reproducing the conference record data, the explainer can see through and the material hidden by the explainer can be seen at the same time.

  When these processes are executed for all the images (when a negative result is obtained in step 1103), the video data conversion unit 108 stores the image data after data conversion in the external storage device 105 (step 1107).

(Meeting record data search operation)
Here, the contents of the processing operation executed when retrieving the minutes data will be described. The contents of this processing operation are executed by the data search device 110.

  In the case of this embodiment, the description location is searched by specifying the material used for the description and the cursor position or range on the material.

  FIG. 12 illustrates the contents of the processing operation executed by the data search apparatus 110.

  First, the data search device 110 acquires the correspondence between the material number 401 and the material name 402, the material size information 403 and 404, and the material data used in the meeting from the external storage device 105 (step 1201). .

  Next, the data search device 110 displays a selection screen for materials to be searched on the screen of the display device 109 (step 1202). FIG. 13 shows an example of the selection screen. In the case of FIG. 13, an example is shown in which information of four materials is displayed so as to be selectable on one screen. FIG. 13 shows a case where each material is displayed as a thumbnail image 1032 and a material name 1303. The user places the cursor 1304 on one of the thumbnail images 1302 displayed on the selection screen 1301, and inputs the selection to the data search device 110 by a click operation. In the figure, the document 1 in a state where the selection has been confirmed is shown in a shaded display.

  Subsequently, the data search device 110 accepts selection of an explanation range to be searched among the selected materials (step 1203). FIG. 14 shows an example of a screen displayed when the selection of the explanation range is accepted. A selection screen 1401 shown in FIG. 14 shows the page contents of “Material 1” selected in Step 1202. The user inputs an explanation range 1402 to be searched by a drag operation for moving the cursor 1403 on the screen. In the figure, an explanatory note and an object located at the lower part of the page are selected. As shown in FIG. 14, the specification of the explanation range can include objects other than characters. This explanation range is stored as cursor position information on the material.

  Next, the data search device 110 reads the cursor position data stored in the external storage device 105 (step 1204). This cursor position data is read in the data format shown in FIG.

  Next, the data search device 110 extracts the time position of the minutes data that is the same material as the material selected as the search target and in which the cursor is located within the selected explanation range (step 1205). When the minutes data in which the cursor is located in the explanation range appears continuously for a plurality of time values, the data search device 110 treats these minutes data as one search result. Thereby, the candidate of an explanation location is searched. FIG. 15 shows a display example of the search result displayed on the display device 109 as the search result. In the search result screen 1501 shown in FIG. 15, four time zones are displayed as candidates.

  Thereafter, the data search device 110 accepts a time zone selection from the selection result screen 1501 with the cursor 1502 (step 1206).

  Thereafter, the data search device 110 reproduces the content of the conference from the selected portion (step 1207).

(Replay of minutes data)
Here, the reproduction operation of the conference record data will be described. This processing operation is also executed by the data search device 110.

  FIG. 16 illustrates the contents of the processing operation executed by the data search device 110.

  First, the data search device 110 reads material data, correspondence between material numbers and material names, and material size information from the external storage device 105 (step 1601).

  Next, the data search device 110 reads data (for example, cursor position information and drawing object information) acquired at the time of the conference from the external storage device 105 in order to reproduce the conference content (step 1602).

  Further, the data search device 110 reads the image data converted by the video data conversion unit 108 from the external storage device 105 (step 1603).

  Furthermore, the data search device 110 reads the voice data acquired from the microphone 103 during the conference from the external storage device 105 (step 1604).

  Thereafter, the data search device 110 determines whether or not the minutes data has ended (step 1605). When the minutes data has not ended (in the case of a negative result in step 1605), the data search device 105 obtains the material number from the minutes data acquired at the time selected on the selection result screen 1501, and the material The material data corresponding to the number is displayed on the display device 109 (step 1606). At the same time, the audio data stored at the same time is reproduced (step 1608).

  Next, the data search device 110 displays the image data of the explainer corresponding to the time in duplicate on the document at a predetermined position (step 1607). This processing operation is repeated until the time of the minutes data ends. FIG. 17 shows an example of a playback screen. The reproduction screen 1701 includes a material screen 1702, a cursor 1703, and an explainer image 1704. As shown in FIG. 17, by displaying the presenter image 1704 superimposed on the material, it is possible to realize the reproduction of a conference record that is more realistic than when only the cursor 1703 is displayed. However, since the explainer image 1704 is a composite image, when priority is given to the visibility of the document, the transparency of the explainer image 1704 can be increased or hidden (transmittance 100%).

  In the case of this embodiment, the content displayed on the material screen 1702 is an image generated from the material data itself, unlike the captured image. Therefore, even when a zoom image of the material is used during the description, clear characters can be displayed.

(Other examples)
In the above-described embodiment, a case has been described in which the cursor position on the document display surface is detected through an operation input of the explainer's finger or an electronic pen. However, the cursor position may be input by a mouse or other input device connected to the computer 104, for example.

  In the above-described embodiment, the case where the cursor position on the electronic board 101 is read from the external storage device 105 and then converted to the cursor position on the material has been described. However, the cursor position on the electronic board 101 input from the computer 104 may be stored in the external storage device 105 after being converted into the cursor position on the document in real time.

  In the case of the above-described embodiment, the case has been described in which video data captured by the camera 102 is converted into image data at the storage timing of conference record data, and the converted image data is converted. However, the video data itself may be converted and superposed on the minutes data as a moving image.

  In the case of the above-mentioned form example, it demonstrated from the viewpoint of a search and its reproduction | regeneration. However, if the conference record data stored in the conference record system according to the embodiment is simply reproduced from the top, it can be used for checking the content of the conference offline.
