Description

  The present invention relates to an image processing apparatus that processes document images such as presentation materials and conference materials.

  Conventionally, when a presenter gives a presentation, a presentation material is often projected onto a large screen using a projector or the like. If the presenter directly writes in advance the contents of this presentation material in advance, the material becomes difficult to see when projected on a large screen. For this reason, it is a common practice for presenters to collect explanation contents separately from presentation materials to be projected on a large screen and store them in a computer or the like. As an example, when a presenter creates and saves presentation materials and supplementary materials separately in advance and displays the presentation materials on the display means referred to by the presenter during the presentation, There has been proposed one that is displayed in a superimposed manner (for example, Patent Document 1).

  Participants who view the presentation often take notes during the presentation when there are questions about the presenter's explanation. For example, in the past, distribution material files were delivered individually to conference participants, and the memo information that each participant individually entered was stored on the distribution material as a display material. Have been proposed (for example, Patent Document 2).

Upon receiving additional information input from each user, the image processing apparatus 2 updates the document image data by superimposing the additional information on the original document image. When the image processing device 2 outputs the document image to the display device 5 and displays the document image on the screen 7, the image processing device 2 can switch display / non-display of the additional information superimposed on the document image. Hereinafter, the image processing apparatus 2 will be described in more detail.

  FIG. 2 is a block diagram illustrating an example of the internal configuration of the image processing apparatus 2. The image processing apparatus 2 includes a control unit 20 that controls each unit, an operation panel 21 that serves as a user interface when a user directly operates the information device 10, a scanner unit 22 that reads a document and generates image data, and an image A printer unit 23 that performs print output based on data, a storage device 24 configured by a hard disk device and the like, and a network interface 25 for performing data communication with other devices via the network 6 are provided.

  The storage device 24 stores various programs and various data. Among them, as information related to the presentation support function, user information 26, presentation information 27, and document image data 9 related to presentation materials are stored. The document image data 9 is stored in a predetermined BOX 28 that is a storage area provided in the storage device 24.

  The user information 26 is information in which a user who uses the image processing apparatus 2 is registered in advance. FIG. 3 is a diagram illustrating an example of the user information 26. As shown in FIG. 3, information related to a plurality of users A, B, C, and D is registered in the user information 26. Specifically, it is information in which a user ID, a password, an e-mail address, a group, and a job title are registered for each user. The user ID and password are identification information for identifying the user. The e-mail address is destination information when an e-mail is transmitted to each user. The group is information regarding a group to which each user belongs. Furthermore, the title is information on the title of each user. Further, the user information 26 may include information other than the information shown in FIG.

  The control unit 20 includes a CPU and a memory (not shown). When the CPU executes a predetermined program, the control unit 20 operates various functions such as the above-described copy function, scanner function, printer function, and presentation support function. In particular, when the presentation support function is activated, the control unit 20 functions as a presentation information registration unit 31, a Web page creation unit 32, and a document image output unit 35 as shown in FIG.

  The presentation information registration unit 31 is a processing unit that registers the presentation information 27 and the document image data 9 in the image processing apparatus 2. For example, a user A who is a presenter logs in to the image processing apparatus 2 by directly operating the operation panel 21 or performing a remote operation from the information processing terminal 3a, and causes the presentation information registration unit 31 to function. Thus, the document image data 9 can be stored in the BOX 28 and the presentation information 27 can be registered. The presenter registers these pieces of information in the image processing apparatus 2 before starting the presentation.

  The presentation information 27 is information in which participants in conferences and presentations are registered. FIG. 4 is a diagram illustrating an example of the presentation information 27. As shown in FIG. 4, the presentation information 27 includes, for example, information indicating a meeting or presentation name, a holding place, a holding time, a storage location of the document image data 9 related to the presentation material, and a user name of the presenter. Information and information related to the user name of the participant who views the presentation are registered. By registering such presentation information 27 in advance by the presenter, the image processing apparatus 2 can store the storage location of the document image data 9 and the user names of the presenter and participants in association with each other.

  FIG. 5 is a diagram illustrating an example of the document image data 9. The document image data 9 is composed of document images G1, G2, G, 3, G4 composed of a plurality of pages. Such document image data 9 is created, for example, when the presenter performs an editing operation while operating the information processing terminal 3a. The presentation information registration unit 31 stores the document image data 9 received from the information processing terminal 3 a via the network 6 in the BOX 28 designated by the presentation information 27. Note that the document image data 9 shown in FIG. 5 is original data created to be displayed on the screen 7 when the presenter makes a presentation, and shows a state before additional information is superimposed.

  When the document image data 9 as shown in FIG. 5 is stored in the BOX 28, the presentation information registration unit 31 analyzes the document image included in the document image data 9 and identifies character decorations that are not used in the document image on each page. To do. This character decoration is, for example, a text color, a shading decoration, a frame decoration, or the like. When the presentation information registration unit 31 specifies a character decoration that is not used in the document image of each page, the presentation information registration unit 31 registers the specified character decoration in the character decoration list. The character decoration registered in the character decoration list is a candidate for determining the character decoration of the additional information when the additional information is superimposed on the document image. Although not shown, this character decoration list is stored in a state stored in the storage device 24, for example.

  When the presentation information registration unit 31 registers the presentation information 27 and the document image data 9 as described above in the image processing apparatus 2, the presentation information registration unit 31 refers to the user information 26 and registers the users A and B registered as the presenters and participants of the presentation. , C, and D are read out, and an email indicating that the presentation information 27 is registered is transmitted to each user A, B, C, and D. This e-mail includes access information for accessing the registered document image data 9. As a result, the users A, B, C, and D operate their own information processing terminals 3a, 3b, 3c, and 3d to start the browser program, and the image processing device 2 is based on the access information included in the e-mail. By accessing, document images based on the document image data 9 can be displayed and viewed on the information processing terminals 3a, 3b, 3c, 3d before the presentation starts or during the presentation. Become.

  Next, when there is an access from the information processing terminals 3a, 3b, 3c, and 3d of the users A, B, C, and D, the Web page creation unit 32 performs the information processing terminals 3a, 3b, 3c, and 3d. Is a processing unit for creating a Web page for enabling browsing of document images. The web page creation unit 32 creates different web pages for each of the users A, B, C, and D. In particular, the web page creation unit 32 refers to the presentation information 27 to determine whether the accessing user is a presenter or a participant, and for the presenter user A, a web page dedicated to the presenter. Is created and transmitted to the information processing terminal 3a, and for the users B, C, and D who are participants, a Web page dedicated to the participant is created and individually transmitted to each of the information processing terminals 3b, 3c, and 3d To do.

  As shown in FIG. 2, the Web page creation unit 32 includes an additional information addition unit 33 and a display setting unit 34.

  The additional information adding unit 33 receives an input operation of additional information for the document image in the Web page created for each user as described above, and is stored in the storage device 24 by superimposing the additional information on the document image. It is a processing unit that updates the document image data 9 being stored. The additional information adding unit 33 adds identification information (for example, a user name) for identifying the user to the additional information input by the users A, B, C, and D, and superimposes them on the document image.

  Further, when the additional information adding unit 33 superimposes the additional information on the document image, the additional information adding unit 33 applies the character decoration individually selected by the user from the character decorations registered in the character decoration list described above to the additional information. Thus, the additional information input by each user A, B, C, D is subjected to a unique decoration process that is not included in the document image. As a result, the individual additional information can be superimposed on the document image in a state where the user who added the additional information can be identified. The additional information adding unit 33 applies the specific character decoration included in the character decoration list to the additional information added by one user, and then deletes the specific character decoration from the character decoration list. Is preferred.

  As described above, the additional information adding unit 33 of the present embodiment adds identification information for identifying the user to the additional information input by each of the users A, B, C, and D, and uses it in the document image. The user who has input the additional information can be identified by applying character decoration that is not performed, but the present invention is not limited to this. That is, only the identification information may be added to identify the user, or the user may be identified by applying only unique character decorations that are not used in the document image.

  As described above, the additional information adding unit 33 receives the additional information input by the users A, B, C, and D before the start of the presentation or during the presentation, as the information processing terminals 3a, 3b, 3c, and 3d. Is added to the document image in a state where it is superimposed on the document image, and the document image data 9 is updated to data to which the additional information is added.

  The display setting unit 34 displays additional information superimposed on the document image as a setting for outputting the document image included in the document image data 9 to the display device 5 after the presentation is started. Alternatively, it is a processing unit for setting non-display. The display setting unit 34 receives a setting operation related to display or non-display of additional information superimposed on a document image on a Web page created for each user by the Web page creation unit 32. In other words, the display or non-display setting of the additional information superimposed on the document image can be set for each user who has input the additional information. The display setting unit 34 displays or hides additional information superimposed on the document image of each page included in the document image data 9 based on the setting operation performed by each user A, B, C, D. Set for each. Further, such setting of display or non-display of additional information is performed in units of pages.

  In the initial state, the display setting unit 34 sets all additional information superimposed on the document image of each page to non-display. When a setting operation for displaying additional information is performed by any one of the users A, B, C, and D, the additional information input by the user specified by the setting operation is switched to display setting. However, the display setting unit 34 may accept only setting operations by the user A who is a presenter, and may not accept setting operations from other users B, C, and D who are participants.

  Next, the document image output unit 35 reads out the document image for one page from the document image data 9 stored in the BOX 28 based on an instruction input from the information processing terminal 3a of the user A who is a presenter, and displays it. 5 is a processing unit that outputs the data. When the display setting unit 34 is set to display additional information, the document image output unit 35 outputs the document image on which the additional information is superimposed to the display device 5 as it is. On the other hand, when non-display of additional information is set by the display setting unit 34, the additional information included in the document image read from the document image data 9 is deleted and output to the display device 5.

  For example, when the additional information added by all users A, B, C, and D is set to non-display by the display setting unit 34, the document image output unit 35 overlaps the document image read from the document image data 9. The additional information input by all the matched users is deleted and output to the display device 5. In this case, the document image output to the display device 5 is the same image as the original document image registered in the BOX 28 by the presentation information registration unit 31.

  On the other hand, for example, when the additional information added by any one specific user by the display setting unit 34 is the display setting and the additional information added by another user is the non-display setting, The image output unit 35 deletes the additional information input by another user superimposed on the document image read from the document image data 9, and the additional information added by the specific user is superimposed on the document image. The data is output to the display device 5 as it is. In this case, the document image output to the display device 5 is an image in which the additional information input by the specific user is superimposed on the original document image registered in the BOX 28 by the presentation information registration unit 31.

  Next, a display screen displayed on the information processing terminal 3a of the user A who is a presenter by the function of the web page creation unit 32 will be described. FIG. 6 is a diagram illustrating an example of the display screen 40 when a Web page dedicated to the presenter is displayed. A document image display area R1 for displaying the document image G1 is provided in the center of the display screen 40 dedicated to the presenter. The document image G1 displayed in the document image display region R1 can be changed to an image of another page by the user A operating the keyboard of the information processing terminal 3a.

  Further, on the display screen 40 dedicated to the presenter, in the upper part of the document image display area R1, additional information added by each user A, B, C, D of the presenter and the participant when outputting the document image to the display device 5 is displayed. Control boxes 42, 43, 44, and 45 corresponding to the users A, B, C, and D for individually switching between display / non-display and the like are displayed. In the control boxes 42, 43, 44, and 45 corresponding to the users A, B, C, and D, a display button B5 for displaying additional information added by the user, character decoration of the additional information, and the like are provided. A property button B6 for changing is displayed.

  For example, when the user A operates the keyboard of the information processing terminal 3a to move the pointer image MP and clicks the display button B5 in the control box 42 of the user A, the additional information added by the user A Is switched to the display setting, and the document image output from the image processing apparatus 2 to the display apparatus 5 becomes an image in which the additional information added by the user A is superimposed. When the display button B5 is clicked as described above, the display button B5 is changed to a non-display button. When the non-display button is clicked thereafter, the additional information added by the user A is set to non-display again. Return.

  In the display screen 40 dedicated to the presenter, an information addition mode button B1 for switching to an information addition mode for inputting additional information to the document image and a document for the display device 5 are displayed below the document image display area R1. Display start button B2 for starting image output and page update buttons B3 and B4 for switching the page of the document image to be output to display device 5 are displayed. The display start button B2 and the page update buttons B3 and B4 are not displayed when the current time is not the holding time registered in the presentation information 27.

  The user A who is a presenter clicks the information addition mode button B1 when writing the description contents in the presentation as additional information to the document image data 9 stored in the image processing apparatus 2 in advance. As a result, the Web page creation unit 32 can cause the additional information adding unit 33 to function and write additional information into the document image G1 displayed in the document image display region R1.

  FIG. 7 is a diagram illustrating an example of the display screen 40 when the presenter inputs additional information on the Web page dedicated to the presenter. As can be seen by comparing FIG. 7 with FIG. 6, in this example, the user A who is a presenter inputs three additional information 51 for the document image G1. The additional information 51 is superimposed on the document image G1 as information added by the user A by the additional information adding unit 33. That is, the additional information adding unit 33 superimposes each of the additional information 51 on the position specified by the user A in the document image G1. When the additional information 51 is overlapped, the additional information adding unit 33 adds a user name (user A) as identification information so that the additional information 51 can be identified by the user A. . In the illustrated example, identification information is added to the head of information added by the user A. Further, the additional information adding unit 33 applies character decorations that are not used in the original document image G1 to the additional information 51, and superimposes the additional information 51 on the document image G1 with the character decorations applied. The contents of the decoration process at this time are stored as a decoration process corresponding to the user A.

  The user A who is a presenter saves the document image data 9 in the image processing apparatus 2 and then inputs the explanation contents in the presentation as such additional information 51 before starting the presentation. In the presentation, the additional information 51 is superimposed on the document image G1 displayed on the information processing terminal 3a, and the additional information 51 is not displayed on the document image G1 output to the display device 5. can do.

  Next, a display screen displayed on the information processing terminal 3b of the user B who is a participant by the function of the Web page creation unit 32 will be described. FIG. 8 is a diagram illustrating an example of the display screen 41 when a Web page dedicated to the participant is displayed. 8 illustrates the case where the participant is the user B, but the same applies to the other users C and D. As shown in FIG. 8, a document image display region R1 for displaying the document image G1 is provided at the center of the display screen 41 dedicated to the participant, as described above. The document image G1 displayed in the document image display area R1 can be freely changed to an image on another page by the user B operating the keyboard of the information processing terminal 3b.

  In addition, on the display screen 41 dedicated to the participant, an upper part of the document image display area R1 is used to switch display / non-display of additional information added by the user B when the document image is output to the display device 5. One control box 43 corresponding to the user B is displayed. In the control box 43 corresponding to the user B, a display button B5 for displaying additional information added by the user B and a property button B6 for changing the character decoration of the additional information are displayed. Thus, the participant-specific display screen 41 can handle only the additional information added by the participant himself / herself.

  For example, when the user B operates the keyboard of the information processing terminal 3b to move the pointer image MP and clicks the display button B5 in the control box 43, the additional information added by the user B is displayed. The document image output from the image processing device 2 to the display device 5 is an image in which the additional information added by the user B is superimposed.

  In addition, on the display screen 41 dedicated to the participant, an information addition mode button B1 for switching to an information addition mode for inputting additional information to the document image is displayed below the document image display area R1. The user B clicks the information addition mode button B1 before writing the presentation, or while writing the question, etc. regarding the contents of the document image G1 as additional information. As a result, the Web page creation unit 32 can cause the additional information adding unit 33 to function and write additional information into the document image G1 displayed in the document image display region R1.

  FIG. 9 is a diagram illustrating an example of the display screen 41 when the participant inputs additional information on the participant-specific Web page. As can be seen by comparing FIG. 9 with FIG. 8, in this example, the user B who is a participant inputs two additional information 52 to the document image G1. The additional information 52 is superimposed on the document image G1 as information added by the user B by the additional information adding unit 33. That is, the additional information adding unit 33 superimposes each of the additional information 52 on the position designated by the user B in the document image G1. When the additional information 52 is overlapped, the additional information adding unit 33 adds a user name (user B) as identification information so that the additional information 52 can be identified by the user B. . Further, the additional information adding unit 33 applies character decorations that are not used in the original document image G1 to the additional information 52, and superimposes the additional information 52 on the document image G1 with the character decorations applied. Also at this time, the contents of the decoration process are stored as a decoration process corresponding to the user B.

  The user B who is a participant, after the document image data 9 is stored in the image processing apparatus 2, operates the information processing terminal 3b to freely write his / her questions and the like in the document image G1, thereby giving a presentation. It is possible to speak without forgetting the questions during the question-and-answer session after the session ends.

  Next, FIG. 10 is a diagram showing an example of a display screen displayed when the property button B6 of the control boxes 42, 43, 44, 45 is operated. The display screen shown in FIG. 10 is also created by the Web page creation unit 32 and provided to each information processing terminal 3a, 3b, 3, 3d. This property display screen is a screen for performing various settings for additional information added for each user. More specifically, the additional information to be set varies depending on which control box property button B6 of the plurality of control boxes 42, 43, 44, 45 is operated. Therefore, the user A who is a presenter can make settings for additional information added by all the users A, B, C, and D, but the users B, C, and D who are participants can be added by themselves. It is possible to set only the additional information.

The display screen of this property, and additional information name input column 46 for recording the name for additional information by each user adds a text color selection column 47 for selecting the text color of the additional information, Te key strike A character decoration selection field 48 for selecting character decorations other than colors is displayed. Each user can input a name for the additional information input by himself / herself in the additional information name input field 46 as necessary. When the user clicks the pull-down button 47a on the right side of the text color selection field 47, a list of text colors registered in the character decoration list is displayed, so the user can select the text color of the additional information from the list. You can choose. However, even when the user does not select a text color, the additional information adding unit 33 automatically selects one text color from the character decoration list. When the user clicks the pull-down button 48a on the right side of the character decoration selection field 48, a list of shaded decorations and frame decorations registered in the character decoration list is displayed, so the user applies to the additional information. The decoration process can be selected from the list. However, even when the user does not select the decoration process, the additional information adding unit 33 automatically selects one decoration process from the character decoration list.

  Further, as shown in FIG. 10, the property display screen includes a display button 49a for setting whether or not to display additional information on the Web page viewed by each user A, B, C, and D. A display button 49b is displayed. The display button 49a and the non-display button 49b are buttons that can be alternatively selected by the user, and in the illustrated example, the display button 49a is selected. When the display button 49a is selected, as shown in FIG. 7 or FIG. 9, the additional information 51, 52 is displayed in a state of being superimposed on the document image G1 displayed in the document image display region R1. The user A who is a presenter can also display the additional information 52 input by the users B, C, and D on the display screen 40 displayed on the information processing terminal 3a. On the other hand, when the non-display button 49b is selected, as shown in FIG. 6 or FIG. 8, the document image G1 displayed in the document image display region R1 is displayed in a state where the additional information 51, 52 is not superimposed. Is done. That is, in this case, the Web page creation unit 32 deletes the additional information 51 and 52 superimposed on the document image G1 and displays it in the document image display area R1.

  In this way, the Web page creation unit 32 receives additional information input by each user A, B, C, D, and updates the document image data 9 by superimposing the additional information on the document image. Further, when outputting the document image to the display device 5, the Web page creation unit 32 sets the additional information added by each user A, B, C, D to the display state or sets the non-display state. The setting operation is accepted. The document image output unit 35 then adds the additional information included in the document image read from the document image data 9 based on the display setting or non-display setting set for each additional information input by each user A, B, C, D. Is output to the display device 5 as it is, or the additional information is deleted and output to the display device 5.

  Next, a specific operation of the image processing apparatus 2 configured as described above will be described. FIG. 11 is a flowchart illustrating an example of a processing procedure performed when the presentation information 27 is registered in the image processing apparatus 2. This process is a process for realizing the function of the presentation information registration unit 31 described above. For example, the process is repeatedly executed by the control unit 20 at regular time intervals. When this process is started, the control unit 20 determines whether or not new document image data 9 has been input (step S1). If no new document image data 9 has been input (NO in step S1), this process ends. In contrast, if new document image data 9 is input (YES in step S1), the control unit 20 analyzes the document image data 9 (step S2). Then, a character decoration that is not used in the document image of each page is specified, and the specified character decoration is registered in the character decoration list (step S3). The inputted document image data 9 is stored in a predetermined BOX 28 of the storage device 24 (step S4).

  Next, the control unit 20 receives an input of the presentation information 27 (step S5), and stores the presentation information 27 in the storage device 24 (step S6). Thereafter, the control unit 20 transmits an e-mail to each participant registered in the presentation information 27 to notify the storage location of the document image data 9 that is the presentation material (step S7). Thus, the processing procedure performed when registering the presentation information 27 is completed.

  Next, FIGS. 12 to 15 are flowcharts illustrating an example of a processing procedure performed in a state where the presentation information 27 is registered in the image processing apparatus 2. This process is mainly a process for realizing the functions of the Web page creation unit 32 and the document image output unit 35 described above. For example, the process is repeatedly executed by the control unit 20 at regular time intervals.

First, as shown in FIG. 12, when this process is started, the control unit 20 determines whether there is input information from the information processing terminals 3a, 3b, 3c, and 3d (step S10). If there is no input information here, this process ends. On the other hand, if there is input information (YES in step S10), the control unit 20 determines whether the input information is a login request (step S11). When it is a login request, the control unit 20 refers to the user information 26 based on the information included in the login request, and executes a user authentication process (step S 12 ). For example, since the login request includes a user ID and a password, the control unit 20 executes the user authentication process by determining whether or not such information is registered in the user information 26. As a result, if information that matches the information included in the login request is registered in the user information 26, the authentication is successful, and the user specified thereby becomes the login user. The control unit 20 determines whether or not the authentication is successful (step S13). If the authentication is successful, the control unit 20 determines whether or not the login user is registered as a presenter in the presentation information 27 (step S14). As a result, if the logged-in user is a presenter (YES in step S14), the control unit 20 reads the document image data 9 already stored (step S15), creates a web page for the presenter, and It transmits to the information processing terminal (step S16). On the other hand, when the logged-in user is registered as a participant in the presentation information 27 (NO in step S14), the control unit 20 reads the document image data 9 already stored (step S17), and for the participant Is created and transmitted to the information processing terminal of the logged-in user (step S18). Thereafter, the logged-in user continues to log in until he / she performs logout operation, and can perform operations on the Web page.

  On the other hand, if the authentication fails in the user authentication process (NO in step S14), the process ends without entering a login state. If the input information is not a login request (NO in step S11), the control unit 20 determines whether or not the input information is input information from a presenter who has already logged in (step S19). As a result, when the input information is from the presenter (YES in step S19), the control unit 20 executes presenter handling processing (step S20). If the input information is not input from the presenter (NO in step S19), the input information is information from a participant who has already logged in, so the control unit 20 executes a participant handling process (step S21). Thereafter, such processing is repeatedly performed.

  13 and 14 are flowcharts showing an example of a detailed processing procedure of the presenter handling process (step S20). When this process is started, the control unit 20 determines whether or not the input information from the presenter is a mode switching instruction when the information addition mode button B1 is operated (step S30). As a result, when it is an instruction to switch the information addition mode, the control unit 20 switches the information addition mode (step S31). For example, the information addition mode is switched from OFF to ON, and the additional information adding unit 33 is caused to function so that the presenter can input additional information to the document image. On the other hand, if the input information is not a mode switching instruction, the process skips to step S31.

  Next, the control unit 20 determines whether or not the input information from the presenter is additional information for the document image (step S32). As a result, if it is additional information, it is determined whether or not the information addition mode at that time is on (step S33). If the information addition mode is ON, presenter identification information to be added to the additional information is generated (step S34), and character decorations that are not used in the document image are determined as character decorations of the additional information (step S34). S35). Thereafter, the control unit 20 superimposes the additional information added by the presenter on the document image, and updates the document image data 9 stored in the BOX 28 of the storage device 24 (step S36). On the other hand, if the input information is not additional information (NO in step S32), or if the information addition mode is off (NO in step S33), the processes in steps S34 to S36 are skipped.

  Next, the control unit 20 determines whether or not the input information from the presenter is a display start instruction due to the operation of the display start button B2 (step S37). As a result, if it is a display start instruction, it is determined whether or not the current time is the holding time registered in the presentation information 27 (step S38). If it is the holding time, the document image of the first page is read from the document image data 9 of the BOX 28 (step S39). If there is additional information superimposed on the document image, the control unit 20 deletes all the additional information (step S40). Here, for example, since the identification information of the user who added the additional information is added to the additional information, all the information to which the identification information is added is deleted. In addition to this, since the additional information has a text color that is not used in the original document image, all the additional information can be obtained by performing a filtering process that transmits colors other than the text color of the additional information. Can be deleted. Then, the control unit 20 outputs the first page document image from which all the additional information has been deleted to the display device 5 (step S41). As a result, the display device 5 displays the document image output from the image processing device 2 on the screen 7. On the other hand, if the input information is not a display start instruction (NO in step S37), or if the opening time has not yet been reached (NO in step S38), the processes in steps S39 to S41 are skipped.

  Next, proceeding to the flowchart of FIG. 14, the control unit 20 determines whether or not the input information from the presenter is a page update instruction by operating the page update buttons B3 and B4 (step S42). As a result, if it is a page update instruction, the document image of the designated page is read from the document image data 9 of the BOX 28 (step S43). If there is additional information superimposed on the document image, the control unit 20 deletes all the additional information (step S44). Again, all additional information is deleted in the same manner as described above. Then, the control unit 20 outputs the document image for one page from which all the additional information has been deleted to the display device 5 (step S45). Thus, the display device 5 updates the document image displayed on the screen 7 based on the document image output from the image processing device 2. On the other hand, if the input information is not a page update instruction (NO in step S42), the processes in steps S43 to S45 are skipped.

  Further, the control unit 20 determines whether or not the input information from the presenter is an instruction to display additional information when any one of the display buttons B5 is operated (step S46). As a result, if it is an instruction to display additional information, the control unit 20 reads again the document image of the page output to the current display device 5 from the document image data 9 of the BOX 28 (step S47). Then, the additional information designated as the display target is specified from the additional information superimposed on the document image (step S48). Then, the control unit 20 determines whether or not other additional information input by the user different from the specified additional information is superimposed on the document image (step S49), and the other additional information is superimposed. If so, it is deleted from the document image (step S50). On the other hand, when other additional information is not superimposed, the process of deleting the additional information may not be performed. Then, the control unit 20 outputs a document image in a state where the specified additional information is superimposed on the display device 5 (step S51). As a result, the display device 5 displays the document image with the additional information superimposed on the screen 7 based on the document image output from the image processing device 2. On the other hand, if the input information is not an instruction to display additional information (NO in step S46), the processes in steps S47 to S51 are skipped. This completes the presenter handling process (step S20).

  Next, FIG. 15 is a flowchart illustrating an example of a detailed processing procedure of the participant handling process (step S21). When this process is started, the control unit 20 determines whether or not the input information from the participant is a mode switching instruction when the information addition mode button B1 is operated (step S60). As a result, when it is an instruction to switch the information addition mode, the control unit 20 switches the information addition mode (step S61). On the other hand, if the input information is not a mode switching instruction, the process skips to step S31.

  Next, the control unit 20 determines whether or not the input information from the participant is additional information for the document image (step S62). As a result, if it is additional information, it is determined whether or not the information addition mode at that time is on (step S63). If the information addition mode is on, participant identification information to be added to the additional information is generated (step S64), and character decorations not used in the document image are further determined as character decorations of the additional information ( Step S65). Thereafter, the control unit 20 superimposes the additional information added by the participant on the document image, and updates the document image data 9 stored in the BOX 28 of the storage device 24 (step S66). On the other hand, if the input information is not additional information (NO in step S62), or if the information addition mode is off (NO in step S63), the processes in steps S64 to S66 are skipped.

  Next, the control unit 20 determines whether or not the input information from the participant is an instruction to display additional information when the display button B5 is operated (step S67). As a result, if it is an instruction to display additional information, the control unit 20 reads again the document image of the page output to the current display device 5 from the document image data 9 of the BOX 28 (step S68). Then, additional information corresponding to the participant is identified from the additional information superimposed on the document image (step S69). Then, the control unit 20 determines whether or not other additional information input by the user different from the specified additional information is superimposed on the document image (step S70), and the other additional information is superimposed. If so, it is deleted from the document image (step S71). On the other hand, when other additional information is not superimposed, the process of deleting the additional information may not be performed. Then, the control unit 20 outputs a document image in a state where only the additional information corresponding to the participant is superimposed on the display device 5 (step S72). As a result, the display device 5 displays the document image with the additional information superimposed on the screen 7 based on the document image output from the image processing device 2. On the other hand, if the input information from the participant is not an instruction to display additional information (NO in step S67), the processes in steps S68 to S72 are skipped. This completes the participant handling process (step S21).

  As described above, the image processing apparatus 2 according to the present embodiment accepts an input operation of additional information with respect to a document image, and superimposes the additional information in a state that can be distinguished from the original document image. The stored document image data 9 is updated. If it is set to display additional information, the document image superimposed on the additional information can be displayed by reading the document image from the storage device 24 and outputting it directly to the display device 5. If it is set to hide the additional information, the document displayed by the display device 5 is deleted by deleting the additional information included in the document image read from the storage device 24 and outputting it to the display device 5. Additional information is not displayed in the image.

  According to such an image processing apparatus 2, the file to be managed for the presentation need only be one file corresponding to the document image data 9 which is first saved and then appropriately updated. For this reason, the number of files to be referred to is reduced, and the display contents can be switched efficiently even when the display contents to be output and displayed on the display device 5 are switched, so that presentations and meetings can be performed efficiently. become able to. In particular, in the question and answer time after the presentation is completed, if the additional information added by each participant is sequentially displayed, the question and answer time can be used efficiently.

  As mentioned above, although embodiment regarding this invention was described, this invention is not restricted to the content mentioned above, A various modification is applicable. For example, in the above-described embodiment, a case where the information device 10 configured by a multifunction peripheral, an MFP, or the like realizes a function as the image processing apparatus 2 is illustrated. However, the above-described function of the image processing apparatus 2 is, for example, a general function. You may implement | achieve with a computer, a server apparatus, etc.

  Further, when receiving the input of additional information to be superimposed on the document image, the additional information adding unit 33 described above may receive a designation as to whether or not the additional information is confidential information. If the input additional information is confidential information, when superimposing the additional information on the document image, secret designation information indicating that the additional information is confidential information is further added to be superimposed on the document image. May be. In this way, for example, when the document image output unit 35 reads the document image and outputs it to the display device 5, the additional information to which the secret designation information is added is deleted from the document image. Can be output to. In this case, the document image output unit 35 determines whether there is a user who cannot know confidential information among presenters and participants based on information on groups of users included in the user information 26 and information on positions. You may make it discriminate | determine. For example, if a presenter or participant includes a user who belongs to another group, or a general job user, a user who cannot know confidential information is included It will be. If there is even one user who cannot know the secret information, the document image output unit 35 outputs additional information including the secret information superimposed on the document image when outputting the document image to the display device 5. May be deleted. With such a configuration, it is possible to prevent secret information from being leaked unexpectedly during a presentation or conference.
