DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
FIG. 1 is a block diagram illustrating a network configuration of an information processing system and a functional configuration of an information processing apparatus according to the embodiment of the present invention. The information processing system according to the embodiment of the present invention includes a plurality of output devices, such as an MFP 200 and a projector 300, and an information processing apparatus 100 connected to a network, such as the Internet and a local area network (LAN). The output devices connected to the information processing apparatus 100 include different types of output devices, such as the MFP 200 and the projector 300 of the embodiment of the present invention.
The MFP 200 is an image forming apparatus having at least any two of a copier function, a printer function, a scanner function, and a facsimile function. In the embodiment of the present invention, the MFP 200 has at least the printer function. The projector 300 has an image display function for projecting as an image a still image or a moving image on a projection surface, such as a screen and a wall.
In the embodiment of the present invention, the output devices exemplarily include the MFP 200 and the projector 300. These are, however, not the only possible output devices; alternatively, the output devices may include, for example, a copier, a scanner, a printer, a facsimile, or any image forming apparatus other than the MFP, and other information output devices (e.g. a personal computer, portable terminals such as a smart phone, and a video conference system).
Each of the output devices including the MFP 200 and the projector 300 transmits output device information relating to each of the output devices to the information processing apparatus 100 at predetermined timing. The output device information includes usage information that indicates usage of each of the output devices. Non-limiting examples of the predetermined timing include various types of timing, such as at every predetermined period of time, upon receipt of a request from the information processing apparatus 100, and upon performance of a predetermined operation.
The information processing apparatus 100 manages the output devices connected to the network. Referring to FIG. 1, the information processing apparatus 100 mainly includes a receiving unit 101, an arithmetic logic unit 102, a calculating unit 103, a determining unit 104, a communication interface 105 (hereinafter referred to as a “communication I/F 105”), and a presenting unit 106.
The information processing apparatus 100 is also connected to a storage unit 150. The storage unit 150 is a storage medium, such as a hard disk drive (HDD) and a storage device. The storage unit 150 may be configured separately from the information processing apparatus 100, in addition to being configured as part of the information processing apparatus 100. The storage unit 150 stores therein the output device information of each of the output devices.
The output device information is associated with each of the output devices and includes the usage information indicating usage of each of the output devices and processing efficiency information indicating processing efficiency of each of the output devices.
In the embodiment, the storage unit 150 stores therein, as the output device information, various types of data including an output device management database (hereinafter referred to as an “output device management DB”) 151, an output mode database (hereinafter referred to as an “output mode DB”) 152, an output management database (hereinafter referred to as an “output management DB”) 153, and usage information 154.
The output device management DB 151 is a database for managing the output devices connected to the network. FIG. 2 is a diagram illustrating an exemplary output device management DB 151. Referring to FIG. 2, the output device management DB 151 registers a model name of each output device, associated with a corresponding ID, a name of a corresponding division that owns the output device, and corresponding processing efficiency per unit time. The division name is referred to when the usage information is tallied for each division or for related purposes. The ID is identification information for uniquely identifying an output device.
The processing efficiency per unit time indicates an efficiency of processing that can be performed per unit time in an output unit that achieves various types of processing in each output device. The output unit is included in each output device, indicating a function for achieving a corresponding output mode. Examples of the output unit include, but not limited to, a function of displaying an image, a function of printing an image, and a function of projecting an image. The processing efficiency per unit time are, specifically, for example, power consumption per unit time, an amount of carbon dioxide discharged per unit time (hereinafter may be referred to as a “CO2 discharge amount”), and throughput per unit when the output unit included in each output device performs processing that can be achieved thereby. Examples of the throughput per unit time include, for example, an output (e.g. display, projection, printing, data transfer) speed per unit time.
The processing efficiency per unit time of each output device may be stored in advance in the output device management DB 151 as associated with the output device. The processing efficiency per unit time of each output device may alternatively be calculated and updated through processing by the information processing apparatus 100 to be described later.
The output mode DB 152 is a database for managing an output mode of the output unit included in each output device connected to the network. FIG. 3 is a diagram illustrating an exemplary output mode DB 152. Referring to FIG. 3, the output mode DB 152 registers an event type associated with a corresponding output mode.
The event type is a type of an event (a ceremony or other occasion) that requires an output of output information by each output device. Examples of the event type include a video conference, an ordinary meeting, and a projector meeting. In the embodiment of the present invention, the video conference requires, as an output performed by each output device, an output of the output mode, for example, reproduction of an image and printing of a document. The ordinary meeting requires, as an output performed by each output device, an output of the output mode, for example, printing of a document used in the ordinary meeting to a paper medium and projection of an image. The projector meeting requires, as an output performed by each output device, an output of the output mode, for example, projection of an image and printing of a document. Types of the output mode corresponding to each event type are not limited to what are recited above.
The event type indicates an output mode of information in the event identified by the above event type. Examples of the output mode include, but not limited to, reproduction of an image, printing of an image, and projection of an image.
The output management DB 153 is a database for managing the output mode and the output unit that can be achieved in each output device. FIG. 4 is a diagram illustrating an exemplary output management DB 153. Referring to FIG. 4, the output management DB 153 registers an output mode that can be achieved in the output unit of each output device, associated with a corresponding output unit for achieving the output mode and a corresponding ID of each output device.
The output mode indicates the output mode of the output information. Examples of the output mode include, but not limited to, reproduction of an image, printing of an image, and projection of an image. The output information refers to information on an object of interest to be output on each output device. Examples of the output information include, but not limited to, image data, voice data, moving image data, and document data of a document to be printed.
Specifically, the output management DB 153 manages the output unit that assumes a function of each output device connected to the network and the output mode that can be achieved by the output unit included in each output device.
The usage information 154 indicates usage of each output device. The usage information 154 may include information that is unique only to each output device. The usage information 154 is received from each output device and stored in the storage unit 150.
FIG. 5 is a diagram illustrating exemplary usage information 154A of the MFP 200 as an example of the usage information 154. Referring to FIG. 5, the usage information 154A of the MFP 200 registers, in addition to control items, such as a model name, a serial number (ID), a model, an installed division, and an applicable month, information indicating usage that corresponds to such management items as power consumption, a CO2 discharge amount, and a sheet output count. It is noted that, of the usage information items recited above, the power consumption and the CO2 discharge amount are used also as the processing efficiency information indicating the processing efficiency of the MFP 200.
FIG. 6 is a diagram illustrating exemplary usage information 154B of the projector 300. Referring to FIG. 6, the usage information 154B of the projector 300 registers, in addition to control items, such as a model name, a serial number (ID), a model, an installed division, and an applicable month, information indicating usage that corresponds to such control items as usage time, power consumption, a CO2 discharge amount, and a CO2 reduction amount. It is noted that, of the usage information items recited above, the power consumption, the CO2 discharge amount, and the CO2 reduction amount are used also as the processing efficiency information indicating the processing efficiency of the MFP 200.
Referring back to FIG. 1, the communication I/F 105 is a communication device, such as a network board.
A collecting unit 107 collects the usage information 154 from each of the output devices including the MFP 200 and the projector 300 by receiving the usage information 154 through the communication I/F 105. The collecting unit 107 stores the collected usage information 154 in the storage unit 150.
The receiving unit 101 receives output object information from a user. The output object information refers to information on each of the output devices connected to the network. In the embodiment, the output object information includes information on an information volume of an object of interest to be output. The information volume of an object of interest to be output indicates a volume of information of the output information of an object of interest to be output (the “object of interest to be output” will hereinafter be referred to as the “output object”) (to be described in detail later). The output information refers to information used through output in an event that requires processing performed in an output unit included in at least one output device out of the output devices. Examples of the output information include, but not limited to, image data, voice data, moving image data, and document data of a document to be printed as described earlier.
The information volume indicates the volume of information of the output object. The information volume includes information on the number of people who share the output object. The information volume also includes information on time relating to the sharing of the output object. Specifically, the output object information includes information on the number of people who share the output object and on time relating to the sharing of the output object. More specifically, in the embodiment, the receiving unit 101 receives as the information volume the number of sheets of documents to be used per one session of a meeting, meeting attendees as the number of attendees at a meeting, meeting time, availability of a handout, and the number of pages of documents to be distributed to each person. In this case, the “meeting attendees” corresponds to the information on the number of people who share the output object and the “meeting time” corresponds to the information on the time relating to the sharing of the output object.
The output object information received by the receiving unit 101 may further include additional information. For example, the output object information may further include the event type and the output information.
In the embodiment, the information processing apparatus 100 displays an output object information receiving screen on the presenting unit 106. Through the output object information receiving screen, the information processing apparatus 100 lets the user input the output object information and the receiving unit 101 receives the output object information thus input.
FIG. 7 is a diagram illustrating an exemplary output object information receiving screen. The output object information receiving screen is displayed on the presenting unit 106 to be described later. Referring to FIG. 7, from the output object information receiving screen, the meeting attendees as the number of attendees at one session of a meeting, meeting time per session, whether printing is required or not, and the number of sheets of documents to be distributed to each person are input as the information indicating the information volume. In the embodiment, a meeting mode is further input. The meeting mode corresponds to the event type.
Referring back to FIG. 1, the arithmetic logic unit 102 calculates the processing efficiency of each output device based on the usage information 154 of each of the output devices stored in the storage unit 150.
For example, arithmetic logic unit 102 calculates the processing efficiency per unit time from the information relating to the processing efficiency included in the usage information 154 of each output device. The arithmetic logic unit 102 then registers the processing efficiency per unit time in the output device management DB 151 of the storage unit 150 by associating the processing efficiency per unit time with the ID of the corresponding output device.
Specifically, referring to FIG. 5, the arithmetic logic unit 102 reads the power consumption for one month (total power consumption) and operating time (omitted in FIG. 5) that assume data relating to the processing efficiency in the usage information 154A of the MFP 200 as an example of the usage information 154. The arithmetic logic unit 102 then calculates the power consumption per unit time as the processing efficiency per unit time of the MFP 200. The arithmetic logic unit 102 further multiplies the power consumption during printing (total power consumption) that represents the data relating to the processing efficiency in the usage information 154A of the MFP 200 by a predetermined CO2 discharge amount calculating coefficient to thereby find the CO2 discharge amount resulting from power consumption during printing. In addition, the arithmetic logic unit 102 reads an estimate of the CO2 discharge amount resulting from sheet output in the usage information 154A of the MFP 200. Then, the arithmetic logic unit 102 adds the estimate of the CO2 discharge amount resulting from sheet output and the CO2 discharge amount resulting from the power consumption during printing to thereby find the CO2 discharge amount per month in the MFP 200. Additionally, the arithmetic logic unit 102 calculates from the CO2 discharge amount per month and the operating time (omitted in FIG. 5) the CO2 discharge amount per unit time and stores the result as the processing efficiency per unit time in the storage unit 150.
In FIG. 5, the processing efficiency per unit time of each output device has been calculated in advance on the side of each output device, so that the arithmetic logic unit 102 may calculate the processing efficiency per unit time of each output device by reading the usage information 154, or calculate the processing efficiency per unit time of each output device using data relating to the processing efficiency included in the usage information 154.
The arithmetic logic unit 102 reads the power consumption (current month) and the CO2 discharge amount (current month) that assume data relating to the processing efficiency in the usage information 154B of the projector 300 (see FIG. 6) as an example of the usage information 154. Then, the arithmetic logic unit 102 calculates power consumption per unit time and CO2 discharge amount per unit time from the usage time (total) of the current month. The arithmetic logic unit 102 then registers these calculated power consumption per unit time and CO2 discharge amount per unit time that represent the processing efficiency per unit time of each output device in the output device management DB 151 of the storage unit 150.
Referring back to FIG. 1, the calculating unit 103 selects, out of the output devices connected to the network, a plurality of first output devices having output units that achieve an output of the output information of the information volume received by the receiving unit 101. In addition, the calculating unit 103 calculates the processing efficiency when each of the first output devices performs processing according to the information volume received by the receiving unit 101, based on the processing efficiency per unit time of each of the first output devices selected earlier.
More specifically, the calculating unit 103 first selects, out of the output devices connected to the network, the first output devices having the output units that achieve an output of the output information of the information volume received by the receiving unit 101. Specifically, the calculating unit 103, for example, reads from the output mode DB 152 output modes associated with the event information received by the receiving unit 101. Then, the calculating unit 103 reads from the output management DB 153 the output unit and the output device ID associated with each of the read output modes.
For example, if the receiving unit 101 has received the event type “ordinary meeting”, the calculating unit 103 reads from the output mode DB 152 each of print and projection that are the output modes associated with the ordinary meeting. The calculating unit 103 then reads, from the output management DB 153, the device IDs associated with the “printing function” and the “projection function” that are the output units associated with the read output modes of print and projection.
The calculating unit 103 thereby selects, out of the output devices connected to the network, the first output devices having the output units that achieve an output of the output information of the information volume received by the receiving unit 101.
Next, the calculating unit 103 calculates the processing efficiency when each of the first output devices selected earlier performs processing according to the information volume included in the output object information received by the receiving unit 101.
If the output object information includes information on the number of people, the calculating unit 103 calculates processing efficiency when the output device (e.g. an image forming apparatus) outputs the output objects for the number of people. If the output object information includes information on a period of time, the calculating unit 103 calculates processing efficiency when the output device (e.g. an image display device) outputs the output object for the period of time based on the period of time.
In calculating the processing efficiency, the calculating unit 103 first translates processing efficiency when processing according to the information volume received by the receiving unit 101 is performed to corresponding second data that indicates processing efficiency of a kind among the first output devices.
The types of the second data indicating the common processing efficiency may be determined in advance by the calculating unit 103. For example, the second data may be a CO2 calculated amount or power consumption. Specifically, as the processing efficiency corresponding to each of the first output devices, the calculating unit 103 translates the processing efficiency of different kinds, for example, the CO2 calculated amount and the power consumption to corresponding second data indicating the processing efficiency of a kind, such as the CO2 calculated amount or the power consumption.
Exemplary calculation of the second data performed by the calculating unit 103 will be described.
It is assumed that the output object information received by the receiving unit 101 has included information indicating the information volume, such as six meeting attendees, a 10-page handout, and 1 hour of meeting time. It is further assumed that, as the first output devices, one MFP 200 and one projector 300 have been selected. A case will be described in which the calculating unit 103 calculates power consumption as the second data indicating the processing efficiency of a common type. In this case, the calculating unit 103 calculates the second data indicating the processing efficiency of a common type as the second data of the MFP 200 as one of the first output devices using Equation (1) given below.

(6 people×10 pages)/(output speed (sheets/minute)×60 minutes)×power consumption per unit time=power consumption during printing (kWh)  (1)

Similarly, the calculating unit 103 calculates the second data indicating the processing efficiency of a common type as the second data of the projector 300 as one of the first output devices using Equation (2) given below.

(1 hour (meeting time: projector utilization time))×power consumption per unit time=power consumption during projection  (2)

The power consumption per unit time in Equations (1) and (2) may be read from the processing efficiency per unit time registered in the output device management DB 151.
It is noted that the calculating unit 103 may calculate the CO2 discharge amount as the second data indicating the processing efficiency of a common type.
In this case, the calculating unit 103 calculates the second data indicating the processing efficiency of a common type as the second data of the MFP 200 as one of the first output devices using Equation (3) given below.

(Power consumption during printing)×CO2 discharge amount calculating coefficient+estimate of the CO2 discharge amount resulting from sheet output=CO2 discharge amount during printing  (3)

In Equation (3), the power consumption during printing is calculated using Equation (1) given earlier.
Additionally, the calculating unit 103 calculates the second data indicating the processing efficiency of a common type as the second data of the projector 300 as one of the first output devices using Equation (4) given below.

(Power consumption during projection)×CO2 discharge amount calculating coefficient=CO2 discharge amount during projection  (4)

In Equation (4), the power consumption during projection is calculated using Equation (2) given earlier.
Referring back to FIG. 1, the determining unit 104 determines the output device based on the output object information received by the receiving unit 101 and the output device information stored in the storage unit 150. In the embodiment, based on the processing efficiency of each of the first output devices calculated by the calculating unit 103, the determining unit 104 determines a first output device having the highest processing efficiency as the output device to output the output information.
Specifically, if the second data is the CO2 discharge amount, the determining unit 104 determines that the processing efficiency is higher with smaller values of the CO2 discharge amount. If the second data is the power consumption, the determining unit 104 determines that the processing efficiency is higher with smaller values of the power consumption.
The presenting unit 106 presents various types of information. In the embodiment of the present invention, the presenting unit 106 displays the output object information receiving screen mentioned earlier and information indicating the output device determined by the determining unit 104. The presenting unit 106 may further display information indicating the processing efficiency when the output device determined by the determining unit 104 performs processing according to the information volume input through the output object information receiving screen.
A determination process performed by the information processing apparatus 100 according to the embodiment as configured as described heretofore will be described below. FIG. 8 is a flowchart illustrating steps in the determination process performed by the information processing apparatus 100 according to the embodiment.
The collecting unit 107 is to receive to collect the usage information 154 from each of the output devices including the MFP 200 and the projector 300 and registers the collected usage information 154 in the storage unit 150.
The information processing apparatus 100 displays the output object information receiving screen illustrated in FIG. 7 on the presenting unit 106 and determines whether the receiving unit 101 has received an input of the output object information from the user (Step S2). If the answer at Step S2 is negative (No at Step S2), the routine is terminated. If the answer at Step S2 is affirmative (Yes at Step S2), the process proceeds to Step S4.
A case in the embodiment will be described in which the receiving unit 101 receives as the output object information the meeting attendees, the meeting time, the meeting mode, and the number of pages of a document per one person, and as the event information, the ordinary meeting.
Then, the arithmetic logic unit 102 calculates the processing efficiency of each of the output devices connected to the network (Step S4) and stores the result in the storage unit 150 (Step S6). If the storage unit 150 stores therein in advance the processing efficiency of each output device, the steps of Step S4 and Step S6 may be omitted.
Next, based on, out of the output devices connected to the network, a plurality of first output devices having output units that achieve an output of an information volume input at Step S2 and processing efficiencies per unit time of the first output devices, the calculating unit 103 calculates a processing efficiency when each of the first output devices performs processing according to the information volume (Step S8).
Then, the determining unit 104 determines, out of the processing efficiencies of the first output devices determined at Step S8, a first output device having the highest processing efficiency as the output device to output the output information (Step S10).
The information processing apparatus 100 then presents on the presenting unit 106 the output device determined at Step S10 and the processing efficiency when the output device performs the processing corresponding to the information volume included in the output object information input at Step S2 (Step S12).
The routine is then terminated.
It is noted that, in the processing at Step S10 described above, the determining unit 104 determines a plurality of first output devices as the first output device having the highest processing efficiency in some cases. This happens when there are a plurality of first output devices having the same processing efficiency. In this case, the determining unit 104 determines, out of the first output devices having the highest processing efficiency, a first output device having the lowest frequency of use. The frequency of use may be read from the usage information 154. Specifically, for example, the usage information 154 is formed to include cumulative operating time and a first output device having the smallest cumulative operating time is to be selected as the first output device having the lowest frequency of use.
This step suppresses occurrence of variations in the frequency of use among the output devices connected to the network.
The performance of the determination process from Step S2 to Step S12 results in, for example, information illustrated in FIG. 9 being displayed 2 on the presenting unit 106.
FIG. 9 is a schematic diagram illustrating an exemplary output screen to be output. Referring to FIG. 9, the output screen displays information that determines the output device determined as the first output device having the highest processing efficiency when processing corresponding to the information volume included in the output object information received from the user is performed (e.g. a name the output device, an installation site of the output device) and the processing efficiency when the output device determined as the first output device having the highest processing efficiency performs the processing corresponding to the information volume included in the output object information input at Step S2. For example, as the information indicating the processing efficiency, the CO2 discharge amount when the first output device performs the processing of the information volume input at Step S2 is presented on the presenting unit 106.
As described heretofore, the information processing apparatus 100 determines the output device to output the output information based on the output object information and the output device information relating to each of the output devices.
Thus, the information processing apparatus 100 according to the embodiment can determine an output device, of the output devices, according to the output object information including information on the output object.
The information processing apparatus 100 according to the embodiment can determine, out of the output devices connected to the network, an output device (a first output device) having the highest processing efficiency when the processing corresponding to the information volume included in the output object information is performed.
In addition, the information processing apparatus 100 according to the embodiment calculates the processing efficiency of each output device based on the usage information 154 of each output device to thereby calculate the processing efficiency of each output device on a real-time basis. Use of this processing efficiency in determining a specific output device enables an output device appropriate according to more current processing efficiency of the output device to be determined.
The information processing apparatus 100 according to the embodiment has a computer-based hardware configuration including a control unit such as a central processing unit (CPU), a storage unit such as read only memory (ROM) and random access memory (RAM), an external storage unit such as a hard disk drive (HDD) and a CD drive, a display unit such as a display, and an input device such as a keyboard and a mouse.
A presentation program to be executed by the information processing apparatus 100 according to the embodiment is provided by being recorded in a computer-readable storage medium such as CD-ROM, a flexible disk (FD), a CD-R, and a digital versatile disk (DVD) as a file in an installable format or an executable format.
The presentation program to be executed by the information processing apparatus 100 according to the embodiment may be configured so as to be provided by being stored in a computer connected to a network, such as the Internet, and later downloaded over the network. The presentation program to be executed by the information processing apparatus 100 according to the embodiment may even be configured so as to be provided or distributed over a network, such as the Internet.
The presentation program to be executed by the information processing apparatus 100 according to the embodiment may still be configured so as to be incorporated in advance in, for example, the ROM.
The presentation program to be executed by the information processing apparatus 100 according to the embodiment has a modular configuration including each of the above-described elements (the receiving unit 101, the arithmetic logic unit 102, the calculating unit 103, the determining unit 104, the presenting unit 106, and the collecting unit 107). A CPU (processor) as actual hardware reads an output device control program from the storage medium and executes it. This loads each of the abovementioned elements on main storage, creating the elements (the receiving unit 101, the arithmetic logic unit 102, the calculating unit 103, the determining unit 104, the presenting unit 106, and the collecting unit 107) on the main storage.
According to the embodiment, it is possible to determine, out of a plurality of output devices, an output device according to the output object information including the information on the output object.
