Since the data C1 is updated to the data C2 by the user B, the return unit 71 displays the data C2 instead of the data C1 in the common display area 125 and assigns the data C1 to the user C having the ownership. Displayed in the third personal display area 123.

  The return unit 71 also identifies the owner of the data displayed in any of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 during the conference period. Among the identified data, data that the user who has logged in at the time of resumption has the ownership of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. It is displayed in the personal display area assigned to the user. However, when the data displayed in any one of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 is updated, the restoration unit 71 updates. , Display the updated data, do not display the data before the update. Here, the data B1 is displayed in the second personal display area 122 during the conference period. However, since the user B has updated the data B1 to the data B2, the restoration unit 71 replaces the data B1 with the data B2. It is displayed in the second personal display area 122 assigned to the user B who has the ownership of B2.

  In addition, the return unit 71 owns the data displayed in any of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 during the conference period. The first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display are the data that the user who has logged in at the time of resumption is identified. The area 124 is displayed in the personal display area assigned to the user. Here, the data displayed in any of the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 during the conference period is data B1, and the user who owns the data is User B. The second personal display area 122 is assigned to the user B when the conference is resumed. Data B1 is updated to data B2. Therefore, the data B2 is displayed in the second personal display area 122.

  FIG. 15 is a flowchart illustrating an example of the flow of the conference support process. The meeting support process is a process executed by the CPU 111 when the CPU 111 provided in the MFP 100 executes a meeting support program stored in the ROM 113, the EEPROM 115, the HDD 116, or the CD-ROM 118A. Referring to FIG. 15, CPU 111 determines whether or not the user has been authenticated (step S01). If the user is authenticated, the process proceeds to step S02; otherwise, the process proceeds to step S05. A user is authenticated by face authentication based on images input from the cameras 140A to 140D. For example, in the case of extracting an area representing a face from an image input from the camera 140D, feature information is extracted from the extracted area, and authentication information including feature information that matches the extracted feature information is stored in the HDD 116. If it is, the user specified by the user identification information included in the authentication information including the feature information that matches the extracted feature information is authenticated.

  In step S02, login of the authenticated user is permitted, and the process proceeds to step S03. In step S03, the position of the user is detected. A user's position is determined based on the position where the camera which imaged the authenticated user among the cameras 140A-140D is arrange | positioned. Specifically, when authenticating a user based on an image output from the camera 140A, the position of the authenticated user is determined on the left side of the MFP 100, and when authenticating the user based on an image output from the camera 140B, When the authenticated user position is determined on the back surface of MFP 100 and the user is authenticated based on the image output by camera 140C, the authenticated user position is determined on the right side surface of MFP 100 and the image output by camera 140D is output. When the user is authenticated based on the above, the position of the authenticated user is determined in front of the MFP 100.

  Here, a case will be described as an example where user A is authenticated on the left side of MFP 100, user B is authenticated on the back side of MFP 100, and user C is authenticated on the right side of MFP 100.

  Then, the user authenticated in step S01 and the position detected in step S03 are associated with each other and stored in HDD 116 (step S04). Specifically, a set of user identification information for identifying the user and position identification information for identifying the position is stored in a predetermined area of the HDD 116. In the next step S05, it is determined whether a start instruction operation has been accepted. If a meeting instruction operation is accepted, the process proceeds to step S07; otherwise, the process returns to step S01. The meeting designation reception screen listing the meeting identification information for identifying the meeting is displayed on the display unit 120, and the position in the image where the meeting identification information is displayed is detected by the touch panel 130. A start instruction operation for instructing start of a meeting specified by the meeting identification information displayed at the position is received.

  In the next step S06, it is determined whether or not the interrupted conference is resumed. If a meeting record including meeting identification information of the meeting specified by the start instruction operation accepted in step S05 is stored in HDD 116, it is determined that the meeting is resumed. If the conference is resumed, the process proceeds to step S07; otherwise, the process proceeds to step S08.

  In step S07, a conference data display process is executed, and the process proceeds to step S08. Although the details of the conference data display process will be described later, this is a process for reproducing the display of the data displayed on the display unit 120 before the interruption. In step S08, the in-conference process is executed, and the process proceeds to step S09. The in-conference processing includes, for example, processing for moving an image of data displayed on the display unit 120 on the display surface, processing for editing data displayed on the display unit 120, processing for generating new data, and the like. The in-conference process is not limited to these, and may include other processes. In step S09, it is determined whether an end instruction operation has been accepted. If an end instruction operation is accepted, the process proceeds to step S10; otherwise, the process returns to step S08. In step S10, a conference record is generated, the generated conference record is added to and stored in the conference table of HDD 116, and the process ends. A conference record is generated for each data displayed on the display unit 120. The conference record has the data format shown in FIG.

  FIG. 16 is a flowchart illustrating an example of the flow of conference data display processing. The conference data display process is a process executed by the CPU 111 when the CPU 111 included in the MFP 100 executes a conference data display program included in the conference support program stored in the ROM 113, the EEPROM 115, the HDD 116, or the CD-ROM 118A. This is the process executed in step S07 in FIG. Before the conference data display process is executed, the conference, the logged-in user and the position thereof are specified, and the conference record in which the conference identification information of the conference is set in the conference item is stored in the HDD 166. Has been.

  Referring to FIG. 16, CPU 111 provided in MFP 100 determines whether there is a non-participating user (step S21). If there is a non-participating user, the process is output to step S22. If there is no non-participating user, the process proceeds to step S37. The logged-in user is compared with the user who has the ownership of the data displayed on the display unit 120 before the conference is interrupted, and among the logged-in users, the display unit 120 before the conference is interrupted. It is determined whether or not there is a non-participating user other than the user having the ownership of the data displayed in. A user who has the ownership of the data displayed on the display unit 120 before the conference is interrupted is a conference in which the conference identification information of the identified conference is set in the conference item in the conference record stored in the HDD 116. The record is extracted and specified based on the user identification information set in the user field of the extracted conference record. In step S37, the restart display process is executed, and the process returns to the conference support process. Details of the restart display process will be described later.

  In step S22, a warning is given. For example, a message “There are non-participating users. Do you want to display all data?” Is displayed on the display unit 120. In the next step S23, it is determined whether or not an operation permitted by any of the logged-in users has been accepted. If an operation to permit is accepted, the process proceeds to step S37; otherwise, the process proceeds to step S24.

  In step S24, selection of a display mode is accepted. A display mode selection screen is displayed on display unit 120, and a display mode is selected in accordance with a user operation. The display mode includes a shared display mode in which only data displayed in the common display area before the conference is interrupted, a first personal display area 121, a second personal display area 122, and a third personal display area before the conference is interrupted. 123 and the fourth personal display area 124, the personal display mode for displaying only the data displayed in either the common display area and the first personal display area 121, the second personal display area 122, the third And a dual display mode for displaying data displayed in either the personal display area 123 or the fourth personal display area 124. The display mode selection screen includes selectable buttons corresponding to each of the shared display mode, the personal display mode, and the dual display mode, and the user accepts an operation to instruct one of the three buttons according to the display mode selection screen. Select the display mode.

  In step S25, a conference record to be processed is selected, and the process proceeds to step S26. Of the conference records stored in the HDD 116, a conference record in which the conference identification information of the specified conference is set as a conference item is extracted, and one of the extracted conference records is selected as a processing target. . In step S26, it is determined whether or not the data specified in the conference record is pre-update data before being updated. If post-update data identification information is set in the post-update data item of the conference record, it is determined as pre-update data, but if nothing is set in the post-update data item of the conference record, the pre-update Not determined as data. If it is determined to be pre-update data, the process proceeds to step S36; otherwise, the process proceeds to step S27. In step S36, it is determined whether there is a conference record that is not selected as a processing target. If there is an unprocessed conference record, the process returns to step S25; otherwise, the process returns to the conference support process. For this reason, since the CPU 111 displays the updated data on the display unit 120, the CPU 111 does not display the pre-update data on the display unit 120.

  In step S27, a user having ownership of data specified by the conference record is specified. The user specified by the user identification information set in the user field of the conference record is specified.

  In the next step S28, it is determined whether or not the data specified by the conference record has been displayed in the common display area 125 before the interruption. If the area identification information “shared” is set in the item of the display area of the conference record, it is determined that the data specified by the conference record was displayed in the common display area 125 before the interruption. It is determined that it is not displayed in the common display area 125 before the interruption. If the data specified in the conference record is displayed in common display area 125 before the interruption, the process proceeds to step S29; otherwise, the process proceeds to step S33.

  In step S29, it is determined whether or not the display mode selected by the user in step S24 is either the shared display mode or the dual display mode. If either the shared display mode or the dual display mode is selected, the process proceeds to step S30. If not, the process proceeds to step S36.

  In step S30, it is determined whether or not the restriction mode is set. If the restriction mode is set, the process proceeds to step S31; otherwise, the process proceeds to step S32. The restriction mode is set in advance in MFP 100 by the user. In step S31, it is determined whether or not the authority of the data specified by the conference record is set to “permitted”. If the data authority is set to “permitted”, the process proceeds to step S32. If not, the process proceeds to step S34.

  In step S32, the data specified in the conference record is specified in step S21 among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. The information is displayed in areas assigned to login users other than non-participating users, and the process proceeds to step S36. For this reason, the CPU 111 is the data displayed in the common display area 125 before the conference is interrupted in the shared display mode or the dual display mode and in the restricted mode, and the authority is “permitted”. The data set in is displayed in the personal display area assigned to each user who is logged in at the time of resumption and who is not a non-participating user. In the case of the shared display mode or the dual display mode, and the restricted mode, the CPU 111 is the data displayed in the common display area 125 before the conference is interrupted, and the authority is set to “non-permitted”. Data is not displayed in the personal display area assigned to each user who is logged in when resuming and is not a non-participating user.

  In step S34, it is determined whether or not the user specified in step S27 is a logged-in user. If the owner of the data specified by the conference record selected as the process target in step S25 is the login user, the process proceeds to step S35. If not, step S35 is skipped and the process proceeds to step S36. In step S35, the data specified in the conference record is specified in step S27 among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. The information is displayed in an area assigned to each logged-in user, and the process proceeds to step S36.

  For this reason, in the case of the shared display mode or the dual display mode, and the restricted mode, the CPU 111 is data displayed in the common display area 125 before the conference is interrupted, and the authority is “non-permitted”. If the user who owns the data is logged in, the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display In the area 124, the information is displayed in the personal display area assigned to the login user, but is not displayed unless the user having the ownership of the data is logged in.

  In step S33, it is determined whether the display mode selected by the user in step S24 is either the personal display mode or the dual display mode. If either the personal display mode or the dual display mode is selected, the process proceeds to step S34. If not, the process proceeds to step S36.

  In step S34, it is determined whether or not the user specified in step S27 is a logged-in user. If the owner of the data specified by the conference record selected as the process target in step S25 is the logged-in user, the process proceeds to step S34. If not, the process skips step S35 and proceeds to step S36. In step S35, the data specified in the conference record is specified in step S27 among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. The information is displayed in an area assigned to each logged-in user, and the process proceeds to step S36.

  For this reason, the CPU 111 is in the personal display mode or the dual display mode, and before the conference is interrupted, the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area. If the user who owns the data has logged in the data displayed in any of the display areas 124, the first personal display area 121, the second personal display area 122, the third personal display area 123 will be displayed. The fourth personal display area 124 is displayed in the personal display area assigned to the login user, but is not displayed unless the user having the data ownership is logged in.

  In step S36, it is determined whether there is a conference record that is not selected as a processing target. If there is an unprocessed conference record, the process returns to step S25; otherwise, the process returns to the conference support process. In step S25, when the process proceeds from step S36, one of the conference records not yet selected as a processing target is selected as a processing target.

  FIG. 17 is a diagram illustrating an example of the flow of restart display processing. The restart display process is a process executed in step S37 of FIG. Referring to FIG. 17, CPU 111 selects a conference record to be processed (step S51), and advances the process to step S52. Of the conference records stored in the HDD 116, a conference record in which the conference identification information of the specified conference is set as a conference item is extracted, and one of the extracted conference records is selected as a processing target. .

  In step S52, a user having ownership of the data specified in the conference record is specified. The user specified by the user identification information set in the user field of the conference record is specified. In the next step S53, it is determined whether or not the specified user is a logged-in user. If the identified user is a logged-in user, the process proceeds to step S54; otherwise, the process proceeds to step S62. In step S62, it is determined whether there is a conference record that is not selected for processing. If there is an unprocessed conference record, the process returns to step S51. If not, the process returns to the conference data display process. Therefore, the CPU 111 does not display data on the display unit 120 that is a user who has logged in before the conference is interrupted and that is owned by a user who has not logged in at the present time.

  In step S54, it is determined whether or not the data specified by the conference record has been displayed in the common display area 125 before the interruption. If the area identification information “shared” is set in the item of the display area of the conference record, it is determined that the data specified by the conference record was displayed in the common display area 125 before the interruption. It is determined that it is not displayed in the common display area 125 before the interruption. If the data specified in the conference record is displayed in common display area 125 before the interruption, the process proceeds to step S55; otherwise, the process proceeds to step S60.

  In step S55, it is determined whether the data specified by the conference record is updated data after being updated. If the same data identification information as the data identification information set in the data item of the conference record is set in the updated data item of another conference record, it is determined as the updated data. Otherwise, Not determined as updated data. If it is determined that the data has been updated, the process proceeds to step S56; otherwise, the process proceeds to step S57. In step S56, the data specified by the conference record is displayed in common display area 125, and the process proceeds to step S62.

  In step S57, it is determined whether or not the data specified in the conference record is pre-update data before being updated. If it is determined to be pre-update data, the process proceeds to step S58; otherwise, the process proceeds to step S59. In step S58, the user specified in step S53 among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 is selected as the data specified in the conference record. Is displayed in the personal display area assigned to the process, and the process proceeds to step S62. In step S59, the data specified by the conference record is displayed in common display area 125, and the process proceeds to step S62.

  In step S60, it is determined whether or not the data specified in the conference record is pre-update data before being updated. If it is determined to be pre-update data, the process proceeds to step S62; otherwise, the process proceeds to step S61. In step S61, the user specified in step S53 among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 is specified as the data specified in the conference record. Is displayed in the personal display area assigned to the process, and the process proceeds to step S62. In other words, when the data specified in the conference record is updated, the updated data is displayed without displaying the pre-update data, and when the data specified in the conference record is not updated. , Display the data.

  In step S62, it is determined whether there is a conference record that is not selected for processing. If there is an unprocessed conference record, the process returns to step S51. If not, the process returns to the conference data display process. In step S51, when the process proceeds from step S62, one of the conference records not yet selected as a processing target is selected as a processing target.

  In this way, the CPU 111 displays the data displayed in the common display area 125 before the interruption, when the data has been updated, displays the updated data in the common display area 125, Of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124, the data is displayed in the personal display area associated with the user who owns the data and the data. Is not updated, the data is transferred to the user having ownership of the data among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. Display in the assigned personal display area. The CPU 111 updates the data displayed in any of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 before the interruption. If the data is not updated, the updated data is displayed without displaying the pre-update data. If the data is not updated, the data is stored in the first personal display area 121, the second personal display area 122, Of the three personal display areas 123 and the fourth personal display area 124, the data is displayed in the personal display area assigned to the user who owns the data.

  As described above, MFP 100 according to the present embodiment functions as an information processing apparatus, and allows users who are permitted to log in to first personal display area 121, second personal display area 122, different positions on the display surface, Based on an operation performed by a user who is permitted to log in during the conference period in association with either the third personal display area 123 or the fourth personal display area 124, the data that the user owns is acquired, and the acquired data Are displayed in an area associated with the user among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. In addition, after resuming after the conference, one or more non-participating users other than the first user who has ownership of the data displayed on the display unit 120 during the conference period are permitted to log in after resuming after the conference If it is included in the second user, a warning is displayed on the display unit 120, and if not permitted by the user, the data displayed in the common display area 125 during the conference period is not displayed in the common display area 125. For this reason, the data which can be browsed by the user who has not participated before the interruption when the conference is resumed can be limited.

  Further, the MFP 100 selects one of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 based on an operation by a user who is permitted to log in during the conference period. When data displayed on the screen is moved to the common display area 125, an authority indicating whether or not to permit access to the moved data is set, and based on an operation by a user who is permitted to log in during the conference period. The process is executed on the data displayed in any one of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124, and login is permitted during the conference period. Based on the operation performed by the user, the authority to permit access to the data displayed in the common display area 125 is set. On condition Rukoto, to perform the processing. For this reason, the information processing system which can restrict the data which can be accessed by the user who did not participate before interruption at the time of resumption of a meeting can be provided.

  Further, when the conference is resumed, the MFP 100 is displayed in the common display area 125 during the conference period in the shared display mode or the dual display mode in the first state in which the non-participating user is included and is not the restriction mode. Data is transmitted to one or more second users other than the non-participating users who are permitted to log in at the time of resumption among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. Displayed in each of one or more personal display areas associated at the time of restart. For this reason, the user who participated before the interruption can be notified of the data displayed in the common display area before the interruption after the restart.

  Further, when the conference is resumed, the MFP 100 is in the shared display mode or the dual display mode in the first state including non-participating users, and is displayed in the common display area 125 during the conference period in the restricted mode. When the authority of “sharing” is not required for the data, the data is transferred to the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 at the time of resumption. The information is displayed in each of one or more personal display areas associated with one or more second users other than non-participating users who are permitted to log in at the time of resumption. For this reason, the user who participated before the interruption can be notified of the data displayed in the common display area before the interruption after the restart.

  Further, when the conference is resumed, the MFP 100 is in the shared display mode or the dual display mode in the first state including non-participating users, and is displayed in the common display area 125 during the conference period in the restricted mode. When the permission of “permission” for permitting sharing is set for the data, the data is stored in the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. Are displayed on each of one or more personal display areas associated with one or more second users other than non-participating users who are permitted to log in at the time of restart. For this reason, the user who participated before the interruption can be notified of the data displayed in the common display area before the interruption after the restart.

  Further, when the conference is resumed, the MFP 100 is in the shared display mode or the dual display mode in the first state including non-participating users, and is displayed in the common display area 125 during the conference period in the restricted mode. If the authority of “non-permission” that does not permit sharing is set for the data, the first personal display area 121, the second personal if the user who owns the data is permitted to log in when resuming Of the display area 122, the third personal display area 123, and the fourth personal display area 124, the information is displayed in the personal display area associated with the user who has the ownership. For this reason, the user who participated before the interruption can be notified of the data displayed in the common display area before the interruption after the restart.

  In addition, when the conference is resumed, the MFP 100 is in the personal display mode or the dual display mode in the first state where non-participating users are included, and before the conference is interrupted, the first personal display area 121, the second personal If the user who owns the data has logged in the data displayed in any of the display area 122, the third personal display area 123, and the fourth personal display area 124, the first personal display area 121 is displayed. The second personal display area 122, the third personal display area 123, and the fourth personal display area 124 are displayed in the personal display area assigned to the login user. For this reason, the user who participated before the interruption can be notified of the data displayed by the user before the interruption after the restart.

  In addition, after resuming the conference, MFP 100 allows one or more non-participating users other than the first user having ownership of the data displayed on display unit 120 during the conference period to log in after resuming after the conference. If it is included in the second user, the warning is displayed on the display unit 120 and then permitted by the user, or in the second state not including the non-participating user, before the conference is interrupted The user who owns the data logs in the data displayed in any of the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. If there is a login user among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124. The common display area is displayed on the condition that the user who has the ownership of the data is logged in the data displayed in the common display area 125 in the first period. 125. For this reason, when it is permitted by the user who participated before the interruption, the display of the data before the interruption can be reproduced.

  In addition, for the data displayed in the common display area 125 before the interruption and updated before the resumption of the conference, the updated data after the update is displayed in the common display area 125 and updated. Before update, the personal data assigned to the user who owns the data among the first personal display area 121, the second personal display area 122, the third personal display area 123, and the fourth personal display area 124 Display in the display area. For this reason, the user who participates after resumption and does not have the ownership can be notified of the updated data after the interruption. In addition, it is possible to notify the user who has the ownership of the data before being updated.

  In the present embodiment, MFP 100 has been described as an example of the information processing apparatus. However, a conference data display method for causing MFP 100 to execute the conference data display processing illustrated in FIGS.
