It becomes possible to provide.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Embodiment of the present invention
In the present embodiment, “user” refers to, for example, a user account. For example, “the user logs in” means that the use of the function of the device or the like is permitted when the identification information of the user account is successfully authenticated. Also, the “content server” in the figure is a server that manages the content that is a means for realizing the function of image processing and that realizes the function, and corresponds to the “image processing server”.

(Example of image processing system of this embodiment)
FIG. 1 is a diagram illustrating an example of the configuration of an image processing system according to an embodiment of the present invention. The image processing system in FIG. 1 has, for example, two small networks. The first small network is connected to the second small network via the IP network. Each device provided in one small network is identified by a call connection server provided in the small network. Therefore, when one device communicates with another device, for example, communication may be established by obtaining identification information of the partner device from the call connection server. Further, for example, the communication may be performed without acquiring each other's identification information by making the call connection server communicate.

  For example, the first small network may be configured as one LAN. The first small network includes, for example, a multifunction machine 101, a call connection server 202, a user management server 203, a screen management server 204, an image processing server 206, a PC 205, and a PC 207.

  The multifunction machine 101 has, for example, functions of a scanner that inputs an image and a plotter that outputs an image. The multifunction machine 101 may also have, for example, a facsimile machine and a copy function. Further, the multifunction peripheral 101 communicates with the user management server 203, the screen management server 204, or the image processing server 206 by the call connection server 202, and is input to the image processing function of the image processing server 206. Image data processing is instructed, and the image data of the image processed by the image processing server 206 is output.

  The call connection server 202 manages identification information of a device connected to the first small network, transmits the identification information in response to a request from another device, or another device and the first small network. Via communication with a device connected to. The “other device” may be a device connected to the first small network, or may be a device connected to a network outside the first small network, for example. The call connection server 202 may be configured as, for example, a SIP (Session Initiation Protocol) server.

  The user management server 203 manages information on users who use the functions of the device connected to the first small network. For example, the user management server 203 manages authentication information for each user. For example, the user management server 203 may perform authentication based on the authentication information. The user management server 203 may perform authentication by, for example, SIP digest authentication defined in RFC3261.

  Furthermore, the user management server 203 may manage the identification information of the screen data of the operation screen corresponding to the function provided by the image processing server 206 in association with each user. Thereby, when the function permitted for every user differs, the operation screen corresponding to the function permitted can be provided with respect to a user.

  The screen management server 204 manages screen data of a screen displayed on a display device controlled by the multifunction machine 101. The screen data managed by the screen management server 204 is screen data corresponding to each user who uses the multifunction machine 101, and is screen data based on the functions of the image processing server 206 permitted for the user. is there.

  For example, the screen data may be associated with the identification information of the provided function of the image processing server 206 for each position of the operation screen generated by the screen data. The position of the operation screen may be represented by coordinates, for example. Thereby, for example, when the operation screen is displayed on the operation panel or the like of the multifunction machine 101 and an instruction is selected on the operation panel, the operation screen corresponds to the coordinate on which the operation for selecting the instruction is performed. The providing function can be configured to be executed. More specifically, the “operation” information indicating that the coordinates have been selected, or the contents input in the input prompt field provided at the coordinates is transmitted to the screen management server 204.

  In order to realize this, a session for communicating the screen data of the operation screen is established between the screen management server 204 and the multi-function peripheral 101. Furthermore, between the screen management server 204 and the multi-function peripheral 101, A session for communicating operation information or input contents is established. Any of these two sessions may be sessions that transmit and receive data packets on the network. For example, the transport may be either TCP or UDP.

  The image processing server 206 manages “content” corresponding to each function related to image processing, and causes the content to be executed. The image processing server 206 receives the identification information corresponding to each function to be provided from the multi-function peripheral 101 or the screen management server 204, and selects and executes the provided function to be executed.

  The PC 205 communicates with the screen management server 204 to create or edit screen data of an operation screen corresponding to each user. The PC 207 communicates with the image processing server 206, for example, creates means for realizing the functions provided by the image processing server 206 and causes the image processing server 206 to register these means. The PC 207 may further have a function of holding these means. More specifically, when these means are configured as software, they may be storage means for holding a computer program that realizes the software.

  For example, the second small network may be connected to the first small network via an IP network and configured as a service provider. The second small network includes, for example, a call connection server 402, a user management server 403, an image processing server 406, and a PC 407. The call connection server 402 manages the identification information of devices provided in the second small network, and communicates with these devices.

  The user management server 403 performs user authentication when accessing a device provided in the second small network. Similar to the image processing server 206, the image processing server 406 provides an image processing function. The PC 407 communicates with the image processing server 406, creates means for realizing the functions provided by the image processing server 406, and causes the image processing server 406 to register these means.

  The multifunction device 301 does not belong to either the first small network or the second small network, but its function is the same as the multifunction device 101. When using the function provided by the image processing server 206, the multifunction machine 301 communicates with the user management server 203, the screen management server 204, and the image processing server 206 via the call connection server 202. For example, when using the function provided by the image processing server 406, the multifunction machine 301 is connected to the user management server 203 and the screen management server 204 by the call connection server 202, and then further to the call connection server 402. Connect to the user management server 403 and the image processing server 406.

  With these connections, the MFP 301 can execute the same image processing as that of the MFP 101 by the function provided by the image processing server 206 or the image processing server 406.

(Example of operation screen)
FIG. 2 is an example of a display screen displayed by the image input / output device of this embodiment. FIG. 2A is an example of a screen that prompts input of identification information of a user corresponding to the operator. This screen is displayed, for example, on the operation panel of the multi-function peripheral 101 when the power of the multi-function peripheral 101 is turned on and devices such as the scanner, printer, and facsimile machine of the multi-function peripheral 101 become operable. Is done. More specifically, this is realized by the MFP 101 connecting to the screen management server 204 via the call connection server 202 and acquiring screen data of this screen.

  FIG. 2B is a diagram illustrating that an operation screen corresponding to each user is displayed when the user logs in. In FIG. 2B, the screen data corresponding to the user successfully authenticated by the user management server 203 is acquired from the screen management server 204, and the user is permitted to use the screen based on the screen data. The selected operation screen is displayed.

  If authentication fails or authentication is not performed, predetermined guest account screen data held by the screen management server 204 may be acquired and an operation screen for guest accounts may be displayed. . A guest account is, for example, an account of a user who has fewer functions permitted to use than an authenticated user.

(Example of functional configuration of image forming system of this embodiment)
FIG. 3 is a diagram illustrating an example of a functional configuration of the image forming system according to the present embodiment. In FIG. 3, the multifunction machine 101, the call connection server 202, the user management server 203, the screen management server 204, and the image processing server 206 are connected via a network.

Thereby, for example, when the authentication server 231 and the screen information management server 232 are configured as one server, and the user authentication is successful, the identification information of the operation screen corresponding to the user is output. In addition, the identification information can be received as a notification of successful authentication. Therefore, it is possible to simplify communication processing from authentication to acquisition of operation screen identification information.

  The display control unit 141 acquires the screen data from the screen management server 204 based on the identification information of the screen data acquired by the screen information acquisition unit 132 and causes the display unit 171 to display the screen data. Thereby, a different operation screen for every user can be displayed on the display means 171.

When the information is transmitted by the holding function transmission unit 142, the screen management server 204 changes the screen data to a screen corresponding to the function held by the multifunction peripheral 101, and then transmits it to the display control unit 141. can do.

  Accordingly, the display related to the function that is permitted to be used by the user and is not held by the multifunction peripheral 101 can be made different from the display of other functions. Note that “different from the display of other functions” means, for example, distinction from the display of other functions, and for example, the display is changed to image data that does not include the display of the functions that the multifunction peripheral 101 does not hold. You may do it.

  Note that the holding function transmission unit 142 outputs the information to the display control unit 141 instead of the information related to the function held by the holding function transmission unit 142 to the screen management server 204. May be. Accordingly, the display control unit 141 may control the display related to the function not held by the multifunction peripheral 101 based on the input information so as to be different from the display related to other functions.

  Based on the operation screen displayed on the display unit 171, the instruction transmission unit 143 acquires the content of the operation, which is an instruction input by the operator, on the operation screen on which the instruction and the operation of the instruction are performed. Information related to the position is transmitted to the screen management server 204. The instruction output unit 162 acquires information input from the input unit 172 based on the operation screen displayed on the display unit 171. The information to be input is information such as “select” on the operation screen, information input in a column prompting input on the operation screen, and the like.

  If the screen data acquired by the multifunction machine 101 includes identification information of the provided function corresponding to the position of the operation screen, the instruction transmitting unit 143 provides the provided function to the image processing server. An instruction to realize may be output.

  The image transmission / reception unit 161 transmits image data to the image processing server 206 and receives image data processed by the image processing server 206. These image data may be image data input from the image input unit 181, for example.

  The display unit 171 displays a screen controlled by the display control unit 141, for example, an operation screen. The input unit 172 acquires information input by the operator. The display unit 171 and the input unit 172 may be configured as a single operation panel or the like.

  The image input unit 181 is configured as a scanner, for example, and acquires input image data. The image output unit 182 is configured as a plotter, for example, and forms an image based on image data on a medium and outputs the image. The image input unit 181 and / or the image output unit 182 may also be configured as, for example, a facsimile machine, and may further be configured as a unit that communicates with a device such as a PC connected via a network. .
