     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to an information processing method which enables flexible updating of software, and a recording medium. 
         [0004]    2. Description of the Related Art 
         [0005]    As user&#39;s preference has been diversified recently, the importance of so-called customization is important, by which the user uses only a desired function. It also applies to software which controls an MFP. In the software which controls an MFP (including external and internal control), availability of customization according to various demands by the user is a particularly important element. This is because in an environment where plural MFPs are installed as in an office environment, not only the machine types of the MFPs but also the MFP functions which the user wants to use are varied. 
         [0006]    In this manner, in the software which controls an MFP, since the functions which the user wants to use vary, it is important to provide a mechanism which can flexibly cope with customization of the software. Traditionally, mechanisms have been provided to change software with respect to a function dependent on machine type on the basis of machine type information when upgrading the version of the software installed in the device. 
         [0007]    In the technique disclosed in JP-A-2004-227529, the version confirming unit compares the version of the stored printer driver with the version of the printer driver stored in an external file server. If the printer driver stored in the external file server is newer, the new printer driver is acquired by accessing the file server. 
         [0008]    In the technique disclosed in JP-A-2002-222068, information of the latest version of firmware corresponding to the machine type of the local device which is registered to the central control device is acquired, and it is compared with the current version of the firmware of the local device, thereby checking whether there is version update. If it is recognized that there is version update, the new firmware is downloaded and saved from the central control device.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    Hereinafter, an information processing method according to a first embodiment of the invention will be described with reference to the accompanying drawings. 
         [0028]      FIG. 1  is a view schematically showing a configuration of an information processing system to which the information processing method according to the first embodiment of the invention is applied. This information processing system includes an office  1  and a service center  2  which are connected with each other via a communication line  3 . 
         [0029]    The office  1  is provided with plural personal computers (PCs)  11   a ,  11   b  and  11   c , a user server  12 , a multi-function peripheral (MFP)  13 , a high-speed monochrome printer  14 , a scanner  15 , a user authentication server  16 , a database  17 , and a firewall  18 . These devices are connected to a network such as a LAN. Moreover, the user server  12  is connected to the communication line  3  via the firewall  18 . 
         [0030]    The user authentication server  16  manages authentication data about users. In the database  17 , scanned image files, document files, user information, device information, software information and so on are saved. The user server  12  collectively controls signal transmitting operations between these PCs and devices, and also controls update of the version of software incorporated in each device. 
         [0031]    The service center  2  has a software distribution server  21  and a service center authentication server  22 . The software distribution server  21  manages the version of the software incorporated in the entire MFP  13  and also saves the software. The service center authentication server  22  manages authentication data with respect to all users. Then, the software distribution server  21  and the service center authentication server  22  are connected to the communication line  3 . 
         [0032]    As described above, the user server  12  collectively controls signal transmitting operations between the PCs and the devices. For example, when the user server  12  has received a copy instruction signal to the MFP  13  from the PC, the user server  12  converts the signal to a signal controlling copy operation of the MFP  13  and sends it to the MFP  13 . Also, in accordance with an instruction from the PC, the user server  12  outputs a file saved in the DB  17  to the laser printer  14  and saves image data read by the scanner  15 , into the DB  17 . 
         [0033]    Moreover, the user server  12  sends and receives information to and from the service center  2  via the communication line  3 , downloads version update software, and controls version update operation for the software of each device. In this case, the user server  12  acquires data about users from the user authentication server  16 , or gathers information about each device from the device, information about the version of software which controls the device, and so on, and sends the information to the service center  2 . 
         [0034]    On the other hand, at the service center  2 , the software distribution server  21  sends and receives information to and from the service center authentication server  22  on the basis of the data sent from the office  1 , and extracts software to be a subject of version update. Of the extracted software, the software requested by the office is sent to the user server  12 . 
         [0035]    Next, the operation of updating the version of software using this information processing system will be described. In the following description, the operation of updating the version of software which controls the MFP  13  is described as an example. However, the invention of the present application is not limited this embodiment and can also be applied to the operation of updating the version of software of the other devices. 
         [0036]      FIG. 2  is a view showing exemplary software components classified by function unit for controlling the MFP  13 . These software components may be installed in the user server  12  or may be incorporated in the MFP  13 . 
         [0037]    “Job Service” is a software component to operate jobs of the MFP  13  such as copy, scan, fax, and print. “Device Service” is a software component to operate information managed within the device such as counter, log, and serial number of the device. “User Service” is a software component to operate authority to use the device and its related information. “Document Service” is a software component to operate image data managed in the device. 
         [0038]    “Communication Service” is a software component to use a measure of communication to operate the MFP  13 , for example, a communication measure such as HTTP, FTP, SMTP or the like. “Common Service” is a software component that can be used commonly within this software platform. “GUI Service” is a software component which enables switching of the user interface for each user. “New Service” is a software component provided when a new device has appeared or when a new function has been added in the existing device. This means that a software component provided within this software platform can be flexibly added or deleted for each service. 
         [0039]    In the present information processing system, the software components of the above groups are further classified in detail by function unit.  FIG. 3  is a view showing detailed exemplary software components for controlling the MFP  13 . 
         [0040]    “Job Service” has its functions classified further into software components by job, software components by operation, software components by machine type, and software components by option. 
         [0041]    The software components by job include software components to control each job of the MFP  13  such as copy, scan, fax, and print. The software components by operation include software components to control each operation such as save, display, and user interface. The software components by machine type include software components to control each processing operation such as color, monochrome, and mono-color, which are processing functions held by the MFP  13  of the corresponding machine type. The software components by option include software components to control operation of each optional component provided in accordance with a user&#39;s selection, for example, software to control an ADF, finisher, sorter, control panel or the like. 
         [0042]    “Job Service” can also be classified in other ways than the above groups. Moreover, the above groups may be further classified. A software component belonging to one group may be included in software components belonging to another group. The other services than “Job Service” similarly have software components which are further classified in detail. 
         [0043]    The information about the above software components may be saved in the database  17  as software information, or may be managed by the user server  12  or the MFP  13 . This information about the software components includes software version of each software component. Therefore, it has a configuration which enables software management for each software component. 
         [0044]      FIG. 4  is a flowchart showing procedures for updating the version of software by the information processing method according to the first embodiment of the invention. 
         [0045]    In step S 01 , the user server  12  inquires about whether there is version update, to the software distribution server  21  in accordance with a periodic schedule. In step S 02 , the software distribution server  21  checks whether there is version update of software in a recent predetermined period. If there is version update, the software distribution server  21  sends a response that there is version update, to the user server  12 . 
         [0046]    Although not shown, if there is no version update, a response that there is no version update is sent to the user server  12 . The user server  12 , having received this response, stops the subsequent operations, and executes the operation from step S 01  again after the lapse of a predetermined period. In this embodiment the user server  12  periodically inquires about whether there is version update. However, the software distribution server  21  may sends information that there is version update so that the subsequent operations can be executed. 
         [0047]    In step S 03 , the user server  12  extracts, for example, component ID and version as information to univocally identify a software component from the software information in the database  17  and sends them to the software distribution server  21 . In step S 04 , the software distribution server  21  compares the version which the software distribution server  21  itself manages for the software component, with the version sent thereto. Then, the software distribution server  21  extracts a software component which has a difference in version, and sends the component ID of the extracted software component to the user server  12  in step S 05 . 
         [0048]    In step S 06 , the user server  12  displays a list of software components to be subjects of version update, on the display of the PC in accordance with the component ID sent thereto, and thus prompts the manager of the office  1  to carry out a selecting operation. When the manager of the office  1  has selected a desired software component to have its version updated, the component ID of the selected software component is sent to the software distribution server  21 . 
         [0049]    In step S 08 , the software distribution server  21  extracts a corresponding software component in accordance with the component ID sent thereto, and sends the extracted software component to the user server  12  in step S 09 . The user server  12  executes version update by using the software component sent thereto. 
         [0050]    As the software components are subdivided in this manner, then the IDs and versions of the subdivided software components are sent and only a software component having a difference in version is sent and received, the volume of transmission can be reduced. 
         [0051]    In this embodiment, in step S 06 , the manager selects a software component to have its version updated, but this selection may be automatically carried out. 
         [0052]      FIG. 5  is a flowchart showing procedures for updating the version of software by an information processing method according to a second embodiment of the invention. In the second embodiment, the same parts as in the first embodiment are denoted by the same reference numerals and will not be described further in detail. 
         [0053]    In step S 11 , the user server  12  inquires about whether there is version update, to the software distribution server  21  in accordance with a periodic schedule. In step S 12 , the software distribution server  21  checks whether there is version update of software in a recent predetermined period. If there is version update, the software distribution server  21  sends a response that there is version update, to the user server  12 . 
         [0054]    In step S 13 , the user server  12  requests information about machine type and serial number from the MFP  13 . When the information about machine type and serial number is sent from the MFP  13  in step S 14 , the user server  12  checks the software component which is being used by the MFP  13  having these machine type and serial number. Then, for example, the user server  12  specifies a corresponding software component from the software components shown in  FIG. 3 . 
         [0055]    Here, the software components shown in  FIG. 3  are classified into plural categories. Therefore, the same software component is included in plural categories. Thus, when specifying a software component, duplicate specification of the software component is avoided. 
         [0056]    Then, in step S 16 , the user server  12  sends, for example, the component ID and version of the software component as information to univocally identify the specified software component, to the software distribution server  21 . In step S 17 , the software distribution server  21  compares the version which the software distribution server  21  itself manages for the software component, with the version sent thereto. Then, the software distribution server  21  extracts a software component which has a difference in version. 
         [0057]      FIG. 6  is a view showing versions of software components. In  FIG. 6 , all the software components used in the office  1  are of version V1.0.0. Meanwhile, the latest version of a software component that can be used with this machine type is V1.1.0 for “Job Service”. Therefore, in the case where the latest service is to be used, “Job Service” is specified as a subject of version update. 
         [0058]    However, since “Job Service” includes job components such as copy, scan, fax, and print, version management can be carried out on this level. That is, in the case where a new function is added to a part of scan functions, only the scan component is replaced to enable use of the new function. Thus, in this case, the software component related to the scan service is specified as a subject of update, and “Job Service” is not specified as a subject of update. 
         [0059]    In step S 18 , the software distribution server  21  sends the component ID of the extracted software component to the user server  12 . 
         [0060]    The procedures of steps S 19  to S 23  are the same as the processing of steps S 06  to S 10  shown in  FIG. 4  of the first embodiment and therefore will not be described further in detail. 
         [0061]    In this manner, according to these procedures, a necessary software component is specified on the basis of the association between software components. Therefore, update of unnecessary software components can be avoided and efficient version update can be expected. 
         [0062]    Also, according to these procedures, even in the case where addition or change is made to the functions of the MFP  13 , a software component appropriate to that MFP  13  can be flexibly specified. For example, in the case where the MFP  13  is a color machine, addition or change can be made to the software component which controls color functions. In the case where option configuration of the MFP  13  differs, addition or change of software depending of an optical can be made. As a software component is thus specified in accordance with the machine type and version, update of software with respect to various configurations can be carried out flexibly and easily. 
         [0063]      FIG. 7  is a flowchart showing procedures for updating the version of software by an information processing method according to a modification of the second embodiment of the invention. 
         [0064]    In step S 31 , the user server  12  inquires about whether there is version update, to the software distribution server  21  in accordance with a periodic schedule. In step S 32 , the software distribution server  21  checks whether there is version update of software in a recent predetermined period. If there is version update, the software distribution server  21  sends a response that there is version update, to the user server  12 . 
         [0065]    In step S 33 , the user server  12  sends information about the machine type and serial number of the MFP  13  to the software distribution server  21 . In step S 34 , the software distribution server  21  checks the software component which is being used by the MFP  13  on the basis of the information about the machine type and serial number. Then, for example, the software distribution server  21  specifies a corresponding software component from the software components shown in  FIG. 3 . Here, when specifying a software component, duplicate specification of the software component is avoided, as described with reference to  FIG. 5  in the second embodiment. 
         [0066]    Then, in step S 35 , the software distribution server  21  inquires about the version of the specified component in the office  1 , to the user server  12 . In step S 36 , the user server  12  sends the version information of the specified software component to the software distribution server  21 . 
         [0067]    In step S 37 , the software distribution server  21  compares the version which the software distribution server  21  itself manages for the software component, with the version sent thereto. Then, the software distribution server  21  extracts a software component which has a difference in version, and sends information to univocally identify the extracted software component, for example, component ID, to the user server  12  in step S 38 . 
         [0068]    The procedures of steps S 39  to S 43  are the same as the processing of steps S 06  to S 10  shown in  FIG. 4  of the first embodiment and therefore will not be described further in detail. 
         [0069]    According to these procedures, similar advantages to those shown in  FIG. 5  of the second embodiment can be achieved. However, unlike the second embodiment, the specification of the corresponding software component in step S 34  is carried out by the software distribution server  21 . The software distribution server  21  has higher processing capability than the user server  12  and can also have abundant device information about the MFP  13 . Therefore, according to these procedures, the load on the user server  12  can be reduced and the software component can be specified more effectively. 
         [0070]    In a configuration where the software of the user server  12  is installed in the MFP  13  and the MFP  13  is responsible for the functions of the above user server  12 , the above-described advantages are particularly significant. 
         [0071]      FIG. 8  is a flowchart showing procedures for updating the version of software by an information processing method according to a third embodiment of the invention. In the third embodiment, the same parts as in the first embodiment are denoted by the same reference numerals and will not be described further in detail. 
         [0072]    In step S 51 , the user server  12  inquires about whether there is version update, to the software distribution server  21  in accordance with a periodic schedule. In step S 52 , the software distribution server  21  checks whether there is version update of software in a recent predetermined period. If there is version update, the software distribution server  21  sends a response that there is version update, to the user server  12 . 
         [0073]    In step S 53 , the user server  12  sends information about user ID and password which specify a user to the software distribution server  21 . This user ID and password is information managed by the software distribution server  21 . In step S 54 , the software distribution server  21  sends the information about the user ID and password to the service center authentication server  22 . 
         [0074]    The service center authentication server  22  authenticates the user on the basis of the user ID and password and sends information about machine time and serial number of the MFP  13  held by the user and information about contract to the software distribution server  21 . In step S 54 , the software distribution server  21  checks the software component which is being used by the MFP  13  in accordance with the information about machine type and serial number and the information about contract with the user. Then, the software distribution server  21  specifies, for example, a corresponding software component from the software components shown in  FIG. 3 . Here, when specifying a software component, duplicate specification of the software component is avoided, as described with reference to  FIG. 5  in the second embodiment. 
         [0075]      FIG. 9  is a view showing software components available to each user as the MFP  13 . “Job Service” and “Device Service” are available to the user A. Of these, only the version of “Job Service” is updated. Therefore, in this case, it is determined that only “Job Service” must be updated. 
         [0076]    On the other hand, “Job Service”, “Device Service” and “User Service” are available to the user B. Of these, the version of “Job Service” and “Device Service” is updated. Therefore, it is determined that these software components must be updated. 
         [0077]    As the information about contract with the user is considered in this manner, not only “New Service” can be added when the user has changed the contract details and a new function is added to the MFP  13 , but also the detailed services can be handled as subjects of update when these services are updated. Also, in the case where the user A does not need the “Job” function, the MFP  13  has only the “Device” function and only the “Device” function is a subject of update. 
         [0078]    In step S 55 , the software distribution server  21  inquires about the version of the extracted software component in the office  1 , to the user server  12 . In step S 56 , the user server  12  sends version information to the software distribution server  21 . 
         [0079]    In step S 57 , the software distribution server  21  compares the version which the software distribution server  21  itself manages for the software component, with the version sent thereto. Then, the software distribution server  21  extracts a software component which has a difference in version, and sends the component ID of the extracted software component to the user server  12  in step S 58 . 
         [0080]    The procedures of steps S 59  to S 63  are the same as the processing of steps S 06  to S 10  shown in  FIG. 4  of the first embodiment and therefore will not be described further in detail. 
         [0081]    According to these procedures, flexible software update corresponding to the contract in addition to the procedures shown in  FIG. 7  can be realized. 
         [0082]      FIG. 10  is a flowchart showing procedures for updating the version of software by an information processing method according to a fourth embodiment of the invention. In the fourth embodiment, the same parts as in the first embodiment are denoted by the same reference numerals and will not be described further in detail. 
         [0083]    In step S 71 , the user server  12  inquires about whether there is version update, to the software distribution server  21  in accordance with a periodic schedule. In step S 72 , the software distribution server  21  checks whether there is version update of software in a recent predetermined period. If there is version update, the software distribution server  21  sends a response that there is version update, to the user server  12 . 
         [0084]    In step S 73 , the user server  12  requests information about history of use of software components, from the MFP  13 . Here, the history of use shows, for example, how many hours each software component is used within a predetermined period. This history of use is information managed by the MFP  13 . In step S 74 , when the information about the history of use of software components is sent by the MFP  13 , the user server  12  decides a software component to be updated and a software component which is not to be updated, on the basis of the history of use. For example, in the case where the time a software component is used is equal to or less than the time defined for each software, it is decided that the software component should not be updated. Otherwise, it is decided that the software component should be updated. 
         [0085]    Then, in step S 76 , the component ID and version of the software component which is decided to be updated are sent to the software distribution server  21 . In step S 77 , the software distribution server  21  compares the version which the software distribution server  21  itself manages for the software component, with the version sent thereto. Then, the software distribution server  21  extracts a software component which has a difference in version, and sends the component ID of the extracted software component to the user server  12  in step S 78 . 
         [0086]    The procedures of steps S 79  to S 83  are the same as the processing of steps S 06  to S 10  shown in  FIG. 4  of the first embodiment and therefore will not be described further in detail. 
         [0087]    These procedures can be used in the following application. A department A of a company frequently uses copy and fax functions, and a department B frequently uses scan and print functions. In this case, available software functions are changed in accordance with the state of use of each function. For example, since the department A frequently uses the copy and fax functions, software components corresponding to them are updated and the user interface is switched to a user interface mainly for the copy and fax functions. Thus, software update to improve convenience for the user is carried out. 
         [0088]      FIG. 11  is a view showing an example where the user interface is changed in this manner. “Scan” and “Print” shown in  FIG. 11  represent button icons. “Scan”, “Copy” and “Print” button icons are displayed before change. After change, the display is changed to “Copy” and “FAX” button icons. As a measure of updating, the information itself which configures the user interface may be changed, or a setting file such as a meta file can be updated to make a changeover. 
         [0089]    Also, in such a changeover operation, for example, a maintenance serviceman confirms the state of use and executes the operation when visiting the client. As this technique is applied in this manner, convenience for the user and easy customization can be secured. 
         [0090]    The procedures described with reference to  FIG. 4  to  FIG. 11  can be properly selectively adopted and executed as a combination.  FIG. 12  is a view showing a representative processing flow of software version update. This flow shows a processing operation carried out by the user server  12  in cooperation with the software distribution server  21 . 
         [0091]    In step S 100 , information about a user, for example, about contract details, is acquired. In step S 101 , information about the device of the MFP  13 , for example, machine type, serial number and the like, is acquired. In step S 102 , a software component to be a subject is specified in accordance with these pieces of information. In step S 103 , the current version and the latest version of the corresponding software component are compared with each other. If it is Yes in step S 104 , that is, if there is a difference in version, update of the software component is executed. 
         [0092]    According to the above-described embodiments, a mechanism can be provided which can flexibly carry out change of software dependent on machine type of the device, addition and change of functions, and provision of software based on user&#39;s purpose. The machines types of devices installed in an office are diverse, and functions demanded by users vary, too. Even in such a circumstance, user&#39;s detailed requests can be dealt with, and therefore user&#39;s demands can be met quickly. It can contribute to improvement in customer satisfaction (CS), reduce the service cost on the product provider side, and further contribute to reduction in total cost (TCO). Thus, customization can be realized which is advantageous to both the user who uses this system and the provider who provides devices such as an MFP. 
         [0093]    In the above embodiments, the user server  12  and the MFP  13  are separated. However, the functions of the user server  12  may be incorporated in the MFP  13 . Also, while the software distribution server  21  distributes an update program in the above embodiments, the present invention is not limited to these embodiments. A serviceman may visit the office  1  where the MFP  13  is installed, and may connect a personal computer (PC) with the MFP  13  on site and send an update program from the PC to carry out updating. 
         [0094]    Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
