FIG. 6 is a flowchart illustrating a flow of transmission processing of image data in an image processing system 1 according to the first embodiment.
First, a user sets a sheet (which is an object to be read)in an image reading unit 240 of the image processing apparatus 200. The image reading unit 240 reads an image of the set sheet (ACT101), and generates image data. The image reading unit 240 outputs the acquired image data to the image management unit 261.
The image management unit 261 generates image information and path information for the acquired image data. The image management unit 261 outputs the image data to the storage unit 220 and stores the image data in a location represented by the path information. The image management unit 261 generates an image management record which includes the image information and the path information. The image management unit 261 registers the generated image management record in the image management table 221.
Next, the two-dimensional code generation unit 262 generates a two-dimensional code which represents the image information and the destination information (ACT102). The two-dimensional code generation unit 262 outputs the generated two-dimensional code to the LCD controller 202. The LCD controller 202 displays the two-dimensional code on the display 201 (ACT103).
A user inputs an operation to capture the two-dimensional code displayed on the display 201 using the user terminal 5. The image capturing unit 53 of the user terminal 5 captures an image of a space in which the image processing apparatus is placed by a capturing operation initiated by the user. The image capturing unit 53 outputs the acquired captured image to the two-dimensional code recognition unit 54. The two-dimensional code recognition unit 54 detects the two-dimensional code from the captured image (ACT104). The two-dimensional code recognition unit 54 acquires image information and destination information represented by the detected two-dimensional code. An email address represented by the destination information is an email address of the image processing apparatus 200. The two-dimensional code recognition unit 54 outputs the image information and the destination information to the email control unit 55. The email control unit 55 generates an email including the image information in a text (ACT105). The email control unit 55 transmits the generated email to the email address of the image processing apparatus 200 represented by the destination information (ACT106).
The email control unit 263 of the image processing apparatus 200 receives the email transmitted from the user terminal 5 in ACT106 (ACT107). The email control unit 263 acquires image information included in a text of the received email. The email control unit 263 selects an image management record having the acquired image information referring to the image management table 221. The email control unit 263 acquires the image path from the selected image management record. The email control unit 263 acquires image data stored in the image path from the storage unit 220. The email control unit 263 generates an email (ACT108), and attaches the acquired image data (ACT109).

The image processing apparatus 200 according to the first embodiment configured in this manner reads a sheet to generate image data. After generating the image data, the image processing apparatus 200 displays a two-dimensional code representing an email address of the image processing apparatus. A user transmits an email to the email address of the image processing apparatus 200 by reading the two-dimensional code using the user terminal 5. Therefore, the user does not need to manually input the email address of the image processing apparatus 200.
In addition, the image processing apparatus 200 transmits email with the image data attached to the email address of the transmission source of the email transmitted from the user terminal 5. Therefore, a user does not need to register an email address as a transmission destination of image data in the image processing apparatus 200 in advance.
The image processing apparatus 200 according to the first embodiment has the function described above, and thereby workload of a user related to an acquisition of the image data is reduced.
Next, a modification example of the first embodiment will be described.
The image processing apparatus 200 may determine a transmission destination of email to which image data is attached according to information included in the received email. For example, the user specifies an email address of a counterpart to whom the user wants to transmit image data in a Cc field, Bcc field, and the like of the email to be transmitted to the image processing apparatus 200. The image processing apparatus 200 transmits the email with the image data is attached to the email address of the transmission source of the received email. Furthermore, the image processing apparatus 200 transmits the email to which image data is attached even to an email address specified in the Cc field, Bcc field, and the like of the received email. The user may easily transmit the acquired image data to a plurality of counterparts by the processing described above. Moreover, for example, the email address specified in the Cc field, Bcc field, and the like may be described instead in a text of email. In this case, a format which allows the email address described in the text of email to be interpreted as an email address of the transmission destination may be provided.
The image processing apparatus 200 may be configured as a device which is integrated with the access point 4.

FIG. 7 is a diagram illustrating a configuration of an image processing system la according to a second embodiment.
The image processing system la includes an image processing apparatus 200a (instead of the image processing apparatus 200 of the image processing system 1). Moreover, the image processing system la includes user terminals 5a-1 to 5a-3 (instead of user terminals 5-1 to 5-3 of the image processing system 1). In addition, the image processing system 1a includes image storage devices 6-1 to 6-3 (which are not included in the image processing system 1).

The description now returns to FIG. 8.
The image reading unit 240a reads a sheet (which is an object to be read) and generates image data. The image reading unit 240a outputs the acquired image data to the image transmission unit 264.
When the image data is output from the image reading unit 240a, the image transmission unit 264 generates path information of the image data. The path information is information of a path at which the image data is stored in the image storage device 6. The image transmission unit 264 refers to the image storage device table 221a and selects the image storage device 6 that is a transmission destination of the image data. The selected image storage device 6 may be selected according to a desired criteria such as a load situation of the image storage device 6, and a disk usage amount. The image transmission unit 264 acquires address information from an image storage device record corresponding to the selected image storage device 6. The image transmission unit 264 transmits image data to the position information represented by the acquired address information. At this time, the image transmission unit 264 transmits both image data and path information of the image data.
The two-dimensional code generation unit 262a generates a two-dimensional code which represents position information and path information of the image storage device 6 to which image data is transmitted. The two-dimensional code generation unit 262a outputs the generated two-dimensional code to the LCD controller 202 and allows the code to be displayed on the display 201.
FIG. 10 is a block diagram illustrating a functional configuration of the user terminal 5a. 
The user terminal 5a is different from the user terminal 5 in that the user terminal 5a includes an image data acquisition unit 56 instead of the email control unit 55.
The image data acquisition unit 56 acquires image data based on the path information and position information acquired from the two-dimensional code recognition unit 54. More specifically, the image data acquisition unit 56 requests transmission of image data stored in a location represented by the path information to the image storage device 6, the path information being included in the position information.
FIG. 11 is a block diagram illustrating a functional configuration of the image storage device 6.
The image storage device 6 includes a CPU, a memory, an auxiliary storage device, and the like. The CPU and the memory are connected by a bus. The CPU performs by reading an image providing program in the memory. Additionally, the image storage device 6 includes a communication unit 61, a storage unit 62, and an image management unit 63. The image providing program controls each functional unit described above.
All or a portion of each function of the image storage device 6 may be achieved using hardware such as ASIC, PLD, and FPGA. The image providing program may be stored in a computer-readable recording medium. For example, the computer-readable recording medium may be a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM. Moreover, the computer-readable recording medium may be, for example, a storage device such as a hard disk embedded in the computer system. The image providing program may be transmitted through the electric communication circuit.
The communication unit 61 includes a communication interface such as a LAN. The communication unit 61 communicates with the image processing apparatus 200a and the access point 4 through the network 3.
The storage unit 62 includes a storage device such as a magnetic hard disk device, and a semiconductor memory device. The storage unit 62 stores image data transmitted from the image processing apparatus 200a. 
The image management unit 63 receives image data and path information of the image data transmitted from the image processing apparatus 200a. The image management unit 63 outputs the received image data to the storage unit 62 and stores the image data in a location represented by the path information. In addition, the image management unit 63 acquires requested image data from the storage unit 62 and transmits the image data to the user terminal 5a according to a request of the user terminal 5a. 
FIG. 12 is a flowchart illustrating a flow of transmission processing of image data in the image processing system la according to the second embodiment.
First, a user sets a sheet (which is an object to be read) in the image reading unit 240a of the image processing apparatus 200a. The image reading unit 240a reads an image of the set sheet (ACT201) to generate image data. The image reading unit 240a outputs the acquired image data to the image transmission unit 264.
When image data is output from the image reading unit 240a, the image transmission unit 264 generates path information of the image data. Then, the image transmission unit 264 refers to the image storage device table 221a and selects the image storage device 6 as a destination that the image data is transmitted to. The image transmission unit 264 acquires the address information from an image storage device record corresponding to the selected image storage device 6. The image transmission unit 264 transmits the image data and path information of the image data to a destination represented by the value of the acquired address information (ACT202).
The image management unit 63 of the image storage device 6 receives image data and path information (ACT203). The image management unit 63 outputs the image data to the storage unit 62 and stores the image data in a location represented by the path information (ACT204).
When processing of ACT202 is completed, the image transmission unit 264 of the image processing apparatus 200a outputs the position information and path information to the two-dimensional code generation unit 262a. The two-dimensional code generation unit 262a generates a two-dimensional code which represents the position information and path information (ACT205). The two-dimensional code generation unit 262a outputs the generated two-dimensional code to the LCD controller 202. The LCD controller 202 displays the two-dimensional code on the display 201 (ACT206).
A user inputs an operation to capture the two-dimensional code displayed on the display 201 using the user terminal 5a. An image capturing unit 53 of the user terminal 5a captures an image of a space in which the image processing apparatus is placed by a capturing operation initiated by the user. The image capturing unit 53 outputs the acquired captured image to the two-dimensional code recognition unit 54.
The two-dimensional code recognition unit 54 detects a two-dimensional code from the captured image (ACT207). The two-dimensional code recognition unit 54 acquires the position information and path information represented by the detected two-dimensional code. The two-dimensional code recognition unit 54 outputs the position information and the path information to the image data acquisition unit 56. The image data acquisition unit 56 requests transmission of the image data stored in a location represented by the path information from the image storage device 6 represented by the position information (ACT208).
The image management unit 63 of the image storage device 6 receives the request of to transmit image data (ACT209).
The image management unit 63 acquires the requested image data from the storage unit 62 and transmits the image data to the user terminal 5a (ACT210). The user terminal 5a receives the image data (ACT211), and outputs the image data to the storage unit 52.
The image processing apparatus 200a according to the second embodiment configured in this manner reads a sheet to generate image data, and transmits the image data to the image storage device 6. When transmitting the image data, the image processing apparatus 200a displays a two-dimensional code which represents the image storage device 6 which stores the image data and the location in which the image data is stored. A user requests transmission of the image data to the image storage device 6 which stores the image data by reading the two-dimensional code using the user terminal 5a. Therefore, the user does not need to manually input information which represents the image storage device 6 storing the image data and the location in which the image data is stored.
The image processing apparatus 200a according to the second embodiment has the function described above, and thereby workload of a user related to an acquisition of the image data is reduced.
Next, a modification example according to the second embodiment will be described.
The image processing apparatus 200a may transmit image data to a plurality of the image storage devices 6-1 to 6-3.
An existing file providing function may be used by the image storage device 6 to transmit the requested image data to the user terminal 5a. For example, this function may be included when the image storage device 6 functions as a file server. In addition, this function may be included, for example, when the image storage device 6 functions as a Hyper Text Transfer Protocol (HTTP) server. When the image storage device 6 functions as an HTTP server, authentication of the user terminal 5a may be performed by a POST request. For example, the image processing apparatus 200a may include account information and password information which are valid only for an acquisition of image data in a two-dimensional code. The user terminal 5a acquires the information from the two-dimensional code, and transmits the information by including this in the POST request, and thereby the user terminal 5a may be authenticated by the HTTP server.
The access point 4 may be a network device with wired connection such as bridges, and routers.
The image storage device 6 may be in a network different from the image processing apparatus 200a. In this case, the image storage device 6 may be configured to be capable to communicate with the image processing apparatus 200a through a network device such as a router and a switch.
The location in which the image data is stored may be determined by the image storage device 6. In this case, the image processing apparatus 200a may acquire path information from the image storage device 6. Moreover, the path information may not be information which directly represents the location in which the image data is stored. For example, the image processing apparatus 200a or the image storage device 6 may include a table which associates a storage location of the image data with identification information of the storage location. In this case, for the path information, the identification information which is associated with the storage location of the image data may be used.
Moreover, codes generated by the two-dimensional code generation units 262 and 262a are not limited to two-dimensional codes. For example, the codes generated by the two-dimensional code generation units 262 and 26227 a may be one-dimensional codes such as a bar code.
According to at least one embodiment described above, an image processing apparatus of the embodiment displays a two-dimensional code. The displayed two-dimensional code is input by a user to a user terminal so as to acquire image data. Thereby workload of the user related to an acquisition of the image data may be reduced.
