     DETAILED DESCRIPTION 
       [0013]    An exemplary embodiment of the present invention will be described below in detail with reference to the drawings. 
         [0014]      FIG. 1  is a schematic diagram illustrating an example of the configuration of an image processing system  2  according to an exemplary embodiment of the invention. As illustrated in  FIG. 1 , the image processing system  2  of the exemplary embodiment of the invention is constituted by terminal apparatuses  4 ,  6 , and  8 , which are personal computers or the like, an image processing apparatus  10  that is connected to the terminal apparatuses  4 ,  6 , and  8  over a network, and an image forming apparatus  12  that is connected to the image processing apparatus  10  over a network. 
         [0015]    Note that, in the example illustrated in  FIG. 1 , three terminal apparatuses and one image forming apparatus are illustrated, however, the number of terminal apparatuses and the number of image forming apparatuses may each be any number that is equal to or larger than 1. 
         [0016]    The terminal apparatus  4 ,  6 , or  8  transmits a job (processing information), such as a print job, to the image processing apparatus  10 . A job transmitted by the terminal apparatus  4 ,  6 , or  8  is transmitted as either an authentication job or a general job. An authentication job is a job that is set so that the job is handled while concealed from a user other than an authenticated user who has performed an operation of generating the job. A general job is a job that is not set to be concealed and handled. 
         [0017]    For example, when printing of a certain document is to be performed, in the case where a user does not want another user to know the details of a print job, such as the name of the user that has printed the document, the content of the document that has been printed, or the number of print copies, the user sets the print job as an authentication job. 
         [0018]    The image processing apparatus  10  memorizes a job received from the terminal apparatus  4 ,  6 , or  8 , performs image processing in accordance with the memorized job, and transmits image data that has been subjected to image processing to the image forming apparatus  12 . The image forming apparatus  12  outputs an image based on the image data that has been received from the image processing apparatus  10  on a sheet. 
         [0019]    Here, the image forming apparatus  12  may be a multi-function machine that has plural functions, such as a print function, a scan function, a copy function, and a facsimile function, or may be a single-function printer that has a print function only. The image processing apparatus  10  memorizes a job relating to a function that the image forming apparatus  12  has. For example, in the case where the image forming apparatus  12  has a facsimile function, the image processing apparatus  10  memorizes a job relating to facsimile transmission, performs image processing for facsimile transmission in accordance with the memorized job, and outputs resulting image data to the image forming apparatus  12 . 
         [0020]    Note that, in the exemplary embodiment, a description is given under the assumption that a job memorized by the image processing apparatus  10  is a job transmitted from the terminal apparatus  4 ,  6 , or  8 . However, the image processing apparatus  10  may read and memorize a job that is stored in a portable storage medium connected to the image processing apparatus  10  or may memorize a job generated by the image processing apparatus  10 . 
         [0021]      FIG. 2  is a block diagram illustrating the hardware configuration of the image processing apparatus  10  in the image processing system  2  of the exemplary embodiment. 
         [0022]    As illustrated in  FIG. 2 , the image processing apparatus  10  has a central processing unit (CPU)  14 , a memory  16 , a storage device  18 , such as a hard disk drive (HDD), a communication interface (IF)  20  for transmitting/receiving data to/from an external apparatus, such as the terminal apparatus  4 ,  6 , or  8  or the image forming apparatus  12 , over a network, and an input/output device  22 . These components are connected to one another via a control bus  24 . 
         [0023]    The CPU  14  performs processing in accordance with a program stored in the memory  16  or the storage device  18  and controls operations of the image processing apparatus  10 . 
         [0024]    Note that, in the exemplary embodiment, a description is given under the assumption that the CPU  14  reads and executes a program stored in the memory  16  or the storage device  18 . However, the program may be stored in a storage medium, such as a compact disc read-only memory (CD-ROM), and provided to the CPU  14  therefrom or the program may be provided via the communication IF  20 . 
         [0025]    The input/output device  22  is a device serving as a display device, which is a display unit that displays information, and as an input accepting device that accepts input made by an operator. In the exemplary embodiment, the input/output device  22  is constituted by a touch panel and a card reader that reads information in a recording medium, such as an integrated circuit (IC) card. Note that, as a matter of course, examples of the input/output device  22  are not limited to touch panels and the input/output device  22  may be constituted by a display apparatus and an input device, such as a keyboard. 
         [0026]      FIG. 3  is a block diagram illustrating the functional configuration of the image processing apparatus  10  implemented by executing a program. 
         [0027]    As illustrated in  FIG. 3 , the image processing apparatus  10  has a job accepting unit  30 , a job memory unit  32 , a print condition setting unit  34 , an image processing unit  36 , an output control unit  38 , a user identification unit  40 , a display control unit  42 , and an operation control unit  44 . 
         [0028]    The job accepting unit  30  accepts data of a print job from the terminal apparatus  4 ,  6 , or  8 . The job accepting unit  30  may accept data of a job from an apparatus other than the terminal apparatuses  4 ,  6 , and  8  as described above. In the case where the image forming apparatus  12  has a function other than a print function as in a multi-function machine, the job accepting unit  30  may accept, in addition to data of a print job, data of a job relating to the function that the image forming apparatus  12  has. 
         [0029]    The job memory unit  32  memorizes data of a job that has been accepted by the job accepting unit  30 . In the exemplary embodiment, the job memory unit  32  stores a job in a folder (storage location) determined in accordance with a predetermined setting to thereby memorize the job. The predetermined setting provides a storage location corresponding to a job and may be configured as desired. The predetermined setting may be configured so that, for example, a job is stored, in accordance with what type of job it is, in a folder corresponding to the job type, a job is stored, in accordance with a user who has performed an operation of generating the job, in a folder corresponding to the user, or a job is stored, in the case where data of the job includes information that specifies a storage location, in the specified storage location. 
         [0030]    The print condition setting unit  34  sets print conditions, such as the number of copies, print density, and the size of a sheet that is an output destination, for a print job memorized by the job memory unit  32 . In the exemplary embodiment, the print condition setting unit  34  sets, under the control of the operation control unit  44  described below, print conditions on the basis of an operation performed by a user. Note that the print condition setting unit  34  may set print conditions so as to make a change to print conditions that have already been set for a job accepted by the job accepting unit  30 . 
         [0031]    The image processing unit  36  performs predetermined image processing on image data for printing that is included in data of a print job memorized by the job memory unit  32 . Note that, in the case where the image forming apparatus  12  has a function other than a print function as in a multi-function machine, for example, the image processing unit  36  may perform image processing corresponding to the function that the image forming apparatus  12  has. 
         [0032]    The output control unit  38  performs control so that image data that has been subjected to image processing performed by the image processing unit  36  is outputted to the image forming apparatus  12  for printout on a sheet. Note that, in the case where the image forming apparatus  12  has a function other than a print function as in a multi-function machine, for example, the output control unit  38  may perform control so that output corresponding to the function that the image forming apparatus  12  has is performed. 
         [0033]    The user identification unit  40  identifies a user who performs an operation on the image processing apparatus  10 . In the exemplary embodiment, the user identification unit  40  identifies a user on the basis of identification information that has been obtained via the input/output device  22 . For example, the user identification unit  40  may obtain identification information of a user by obtaining read information in a recording medium, such as an IC card, via the input/output device  22  or may obtain identification information provided by an input operation that has been accepted by the input/output device  22 . 
         [0034]    In the exemplary embodiment, a user identified by the user identification unit  40  is managed so as to be identified as any one of a general user, an administrator, and a special administrator. The administrator is a user who is responsible for administration of the image processing apparatus  10 , for example, and is given privileges in terms of operation authority, which a general user is not given. The administrator is given operation authority to delete a folder in which no job is stored, delete a general job of another user, or move a general job of another user to a different storage location, for example. The special administrator is given higher operation authority than the administrator, such as operation authority to view the details of an authentication job of another user, for example. Note that the special administrator may be given authority to delete an authentication job of another user. 
         [0035]    The display control unit  42  controls display of data of a job memorized by the job memory unit  32 . Note that, in the exemplary embodiment, a description is given under the assumption that the display control unit  42  performs control on display information to be displayed on the input/output device  22 . However, the display control unit  42  may perform control so as to display information on a display unit other than a display unit that the image processing apparatus  10  has. For example, the display control unit  42  may be configured to display information on a display device included in a terminal apparatus that is connected to the image processing apparatus  10  over a network. 
         [0036]    Specifically, the display control unit  42  performs control, for a job that has been memorized by the job memory unit  32  and that is not concealed, so as to display the details of the job and, for a job that has been memorized by the job memory unit  32  and that is concealed, so as not to display the details of the job but so as to indicate only the presence of the job. In the exemplary embodiment, a general job is a job that is not concealed and therefore the details of the job are displayed. On the other hand, for an authentication job, it is determined, in accordance with a viewing user, whether the job is a job that is concealed from the viewer or a job that is not concealed from the viewer. For example, an authentication job is handled as a job that is not concealed from a creator (owner) of the job and a special administrator while being handled as a job that is concealed from a user other than those described above. Note that the details of display performed by the display control unit  42  are described below. 
         [0037]    The operation control unit  44  controls an operation performed by a user on a job memorized by the job memory unit  32 . An operation may be performed by a user via the input/output device  22  or by using another terminal apparatus, such as the terminal apparatus  4 ,  6 , or  8 . 
         [0038]    The operation control unit  44  not only controls an operation performed by a user on setting of print conditions described above but also controls an operation of deleting a job memorized by the job memory unit  32  and an operation of changing a storage location of a job. Specifically, in the case where an operator identified by the user identification unit  40  has operation authority over an operation target job memorized by the job memory unit  32 , the operation control unit  44  accepts an operation on the job. In the case where an operator identified by the user identification unit  40  does not have operation authority over an operation target job memorized by the job memory unit  32 , the operation control unit  44  does not accept but rejects an operation on the job. Note that the details of determination on whether or not operation authority is given are described below. 
         [0039]    Next, the details of display performed by the display control unit  42  are described below. 
         [0040]      FIG. 4  is a schematic diagram illustrating an example of a management screen displayed in accordance with display control performed by the display control unit  42 . Here, an example of a case where a user identified by the user identification unit  40  as UserA views a management screen is described. The user UserA is a user who is not a special administrator. In the management screen illustrated in  FIG. 4 , the usage state of the storage capacity of the storage device  18  that memorizes data of jobs and a list of memorized jobs are displayed. 
         [0041]    As storage locations of jobs, a folder X, a folder Y, and a folder Z are provided. In the folder X, three jobs, namely, JobA, JobB, and JobC, are stored. Here, the jobs JobA, JobB, and JobC are general jobs. Although not illustrated in  FIG. 4 , a job JobD, which is an authentication job, is stored in the folder Y. Here, it is assumed that a user (owner) who has performed an operation of creating the authentication job JobD is a user UserY, not the user UserA. In this case, the authentication job JobD is a job that is concealed from the user UserA. The folder Z is an empty folder. Note that, in  FIG. 4 , the general jobs and the authentication job are stored in the respective folders, however, a general job and an authentication job may be mixed in one folder. 
         [0042]    As illustrated in  FIG. 4 , for the general jobs JobA, JobB, and JobC, the details of the jobs are displayed, such as the folder in which the jobs are stored, whether or not each of the jobs is a job that is specified to be retained, the names of the owners of the jobs, the reception date/time of the jobs, and the data size of the jobs. Note that retaining of a job is a setting in order to specify that, after processing on a job has been completed, the job memory unit  32  does not delete data of the job but keeps memorizing the data. The retaining of a job is set by an operation performed by a user, for example. In the case of a print job, for example, in the case where a user desires to change the number of print copies and perform printing again on a print job after printing in accordance with the print job has been completed, the user performs setting so as to retain the job. 
         [0043]    As described above, the display control unit  42  performs control so as to display the details of a job that is not concealed, such as a general job. On the other hand, the display control unit  42  performs control so as not to display the details of the job JobD that is concealed from the user UserA but so as to indicate only the presence of the job JobD. In the example illustrated in  FIG. 4 , as an indication of the presence of a concealed job, the number of concealed jobs (“1” in  FIG. 4 ) is displayed. In the example illustrated in  FIG. 4 , the total number of memorized jobs (“4” in  FIG. 4 ) is also displayed. 
         [0044]    Note that it is sufficient that the presence of a concealed job be known and therefore the display control unit  42  may perform control so as to display only the total number of memorized jobs. In this case, the details of three jobs are displayed while the total number of memorized jobs is four and therefore a user recognizes that a concealed job is present. The number of jobs may be displayed for each folder. In the example illustrated in  FIG. 4 , the presence of a concealed job is indicated by displaying the number of concealed jobs, however, a simple indication of the presence/absence of a concealed job may be displayed. Also in this case, the presence/absence of a concealed job may be indicated for each folder. For example, as illustrated in  FIG. 5 , a concealed job may be indicated by using a predetermined character that replaces descriptions of the details of the job so as to make the details unknown. 
         [0045]    Next, a description is given of comparative examples of the display described above.  FIGS. 6A and 6B  are schematic diagrams illustrating display screens, which are comparative examples of display in accordance with control performed by the display control unit  42  according to the exemplary embodiment.  FIG. 6A  illustrates a management screen displayed in the case where a user identified as UserY views the management screen while  FIG. 6B  illustrates a management screen displayed in the case where a user identified as UserA views the management screen. Note that  FIGS. 6A and 6B  illustrate management screens displayed in the case where the same jobs as those described with reference to  FIG. 4  are memorized. 
         [0046]    The management screen illustrated in  FIG. 6A  is a management screen displayed in the case where the user UserY, who is an owner of the authentication job JobD, views the management screen and therefore the details of the authentication job JobD are also displayed in the management screen in addition to the details of the general jobs. As the display of the number of jobs, “4” is displayed, which is the number of jobs, the details thereof being displayed. 
         [0047]    On the other hand, the management screen illustrated in  FIG. 6B  is a management screen displayed in the case where the user UserA, not the user UserY who is an owner of the authentication job JobD, views the management screen. Therefore, the details of the general jobs are displayed but the details of the authentication job JobD, which is concealed from the user UserA, are not displayed. As the display of the number of jobs, “3” is displayed, which is the number of jobs, the details thereof being displayed, and the authentication job JobD is not counted in the number of jobs. In this case, the user UserA recognizes that the number of jobs that are present is three from displayed information, however, the number of jobs actually memorized is four, resulting in an inconsistency. Note that, also in  FIG. 6A , in the case where an authentication job of a user UserZ, not the user UserY who is a viewer, has been memorized, the details of the authentication job of the user UserZ are not displayed and the number of jobs displayed does not count the authentication job in the management screen for the user UserY, resulting in a similar inconsistency. 
         [0048]    In the case where the inconsistency described above arises, when a large number of jobs, the presence of which is not recognized, are memorized in accordance with the setting of retaining a job described above, for example, the storage capacity is exhausted before a user becomes aware of the exhaustion, which may result in a situation where a new job is unable to be memorized. Another situation may arise where, in the case where an administrator recognizes a folder to be empty, in which a concealed job is present, and attempts an operation of deleting the folder, the deletion operation of the folder fails because of the concealed job. As described above, maintainability may be affected. 
         [0049]    On the other hand, in the display control performed by the display control unit  42  as described with reference to  FIG. 4 , confidentiality of a concealed job may be maintained while the presence thereof may be recognized by other users. 
         [0050]    Next, operations performed in order to display a management screen of the exemplary embodiment are described. 
         [0051]      FIG. 7  is a flow chart illustrating an example of operations performed in the image processing apparatus  10 . 
         [0052]    In step S 100 , the user identification unit  40  identifies a user who views a management screen by obtaining identification information of the user via the input/output device  22 . 
         [0053]    In step S 102 , the display control unit  42  counts the number of general jobs and authentication jobs memorized by the job memory unit  32 . Here, the display control unit  42  counts a general job as a job that is not concealed. For an authentication job, the display control unit  42  determines whether or not the authentication job is a concealed job on the basis of the result of the identification performed in step S 100 . 
         [0054]    Specifically, in the case where the user identified in step S 100  is a special administrator, any authentication job is counted as a job that is not concealed from the user identified in step S 100 . In the case where the user identified in step S 100  is not a special administrator, if an owner of an authentication job is the user identified in step S 100 , the authentication job is counted as a job that is not concealed from the user identified in step S 100 . If an owner of an authentication job is not the user identified in step S 100 , the authentication job is counted as a job that is concealed from the user identified in step S 100 . 
         [0055]    In step S 104 , the display control unit  42  determines whether or not the jobs counted in step S 102  include only concealed jobs. If the jobs counted include only concealed jobs, the flow proceeds to step S 106 . If the jobs counted include not only concealed jobs, the flow proceeds to step S 108 . 
         [0056]    In step S 106 , the display control unit  42  displays the number of concealed jobs counted in step S 102 . 
         [0057]    In step S 108 , the display control unit  42  obtains the details of a job that has been memorized by the job memory unit  32  and that is not concealed. 
         [0058]    In step S 110 , the display control unit  42  displays the details of a job that is not concealed, which have been obtained in step S 108  and the number of jobs counted in step S 102 . Note that, as the number of jobs, the number of concealed jobs or the total number of jobs counting the number of concealed jobs is displayed, for example, as illustrated in  FIG. 4 . 
         [0059]    Next, control performed by the operation control unit  44  is described. 
         [0060]      FIG. 8  is a flowchart illustrating an example of control operations performed by the operation control unit  44 . 
         [0061]    In step S 200 , the user identification unit  40  identifies a user who performs an operation on a job by obtaining identification information of the user via the input/output device  22 . 
         [0062]    In step S 202 , the user identification unit  40  determines whether or not the user identified in step S 200  is a special administrator. If the user identified in step S 200  is a special administrator, the flow proceeds to step S 210  and the operation on a job is permitted. If the user identified in step S 200  is not a special administrator, the flow proceeds to step S 204 . 
         [0063]    In step S 204 , the user identification unit  40  determines whether or not the user identified in step S 200  is an administrator. If the user identified in step S 200  is an administrator, the flow proceeds to step S 206 . If the user identified in step S 200  is not an administrator, the flow proceeds to step S 212 . 
         [0064]    In step S 206 , the operation control unit  44  determines whether or not an operation to be performed on an operation target job is an operation on a job that is concealed from the user identified in step S 200 . If an operation is to be performed on an operation target job that is concealed from the user identified in step S 200 , the flow proceeds to step S 208 . If an operation is to be performed on an operation target job that is not concealed from the user identified in step S 200 , the flow proceeds to step S 210 . 
         [0065]    In step S 208 , the operation control unit  44  performs control so as to reject the operation to be performed on the operation target job by the user identified in step S 200 . 
         [0066]    In step S 210 , the operation control unit  44  performs control so as to permit the operation to be performed on the operation target job by the user identified in step S 200 . 
         [0067]    In the case where the user identification unit  40  determines in step S 204  that the user identified in step S 200  is not an administrator but a general user, the operation control unit  44  determines in step S 212  whether or not an operation to be performed on an operation target job is an operation on a job, the owner of which is the user identified in step S 200 . If an operation to be performed on an operation target job is an operation on a job, the owner of which is the user identified in step S 200 , that is, if an operation to be performed on an operation target job is an operation to be performed by a user associated with the operation target job, the flow proceeds to step S 210  and the operation is permitted. If an operation to be performed on an operation target job is an operation on a job, the owner of which is a user other than the user identified in step S 200 , the flow proceeds to step S 208  and the operation is rejected. 
         [0068]    As described above, the operation control unit  44  performs control so as not to permit an administrator, who is a predetermined user, to perform an operation on a job that is concealed and so as to permit an administrator to perform an operation on a job that is not concealed. 
         [0069]    The exemplary embodiment of the present invention has been described above. It may be configured not to indicate the presence of an authentication job to general users. For example, in the case where a viewer is a general user, it may be configured to display a management screen as illustrated in  FIG. 6B  and, in the case where a viewer is an administrator, it may be configured to display a management screen as illustrated in  FIG. 4 . The display control unit  42  may be configured to indicate the presence of a concealed job when the storage capacity of the storage device  18  decreases to a predetermined capacity or below. Furthermore, the job memory unit  32  may be configured to automatically delete a memorized job after a predetermined period of time has elapsed.
