[0007] The present invention will be described in detail below with reference to the embodiments shown in the drawings. Specifically, an example in which the present invention is applied to an MFP (Multifunction Peripheral) equipped with a facsimile function will be described. However, the present invention may also be applied to devices other than MFPs. The above MFP1 is equipped with a scan function in addition to a facsimile function.

[0008] Fig. 1 is a diagram for explaining the hardware configuration of an MFP 1 according to this embodiment. As shown in Fig. 1, the MFP 1 includes a controller 10 and an engine unit 23. The controller 10 and the engine unit 23 are connected by a PCI (Peripheral Component Interface) bus.

[0009] The controller 10 controls the entire MFP 1 and controls drawing, communication, and input from the operation unit. The engine unit 23 includes a printer engine connectable to a PCI bus, and is, for example, a black-and-white plotter, a one-drum color plotter, a four-drum color plotter, a scanner, or a fax unit.

[0010] The controller 10 includes a CPU 11, a north bridge (NB) 13, a system memory (MEM-P) 12, a south bridge (SB) 14, a local memory (MEM-C) 17, an ASIC (Application Specific Integrated Circuit) 16, and a hard disk drive (HDD) 25. The north bridge (NB) 13 and the ASIC 16 are connected by an AGP (Accelerated Graphics Port) bus 15. The MEM-P 12 further includes a ROM (Read Only Memory) 12a and a RAM (Random Access Memory) 12b.

[0011] The CPU 11 controls the overall operation of the MFP 1, and includes a chipset including the NB 13, MEM-P 12, and SB 14, and is connected to other devices via the chipset. The NB 13 is a bridge for connecting the CPU 11 to the MEM-P 12, SB 14, and AGP bus 15, and includes a memory controller that controls reading and writing to the MEM-P 12, a PCI master, and an AGP target. The MEM-P 12 is a system memory used as a memory for storing programs and data, a memory for expanding programs and data, a printer drawing memory, and the like, and includes a ROM 12a and a RAM 12b.

[0012] ROM 12a is a read-only memory used as a memory for storing programs and data, and RAM 12b is a writable and readable memory used as a memory for expanding programs and data and as a printer drawing memory. SB 14 is a bridge for connecting NB 13 to PCI devices and peripheral devices. SB 14 is connected to NB 13 via a PCI bus, and a network interface (I / F) unit may be connected to the PCI bus.

[0013] The ASIC 16 is an IC (Integrated Circuit) for image processing applications that has hardware elements for image processing, and realizes a bridge function that connects the AGP bus 15, the PCI bus, the HDD 25, and the MEM-C 17. The ASIC 16 includes a PCI target and an AGP master, an arbiter (ARB) that is the core of the ASIC 16, a memory controller that controls the MEM-C 17, a plurality of DMACs (Direct Memory Access Controllers) that rotate image data using hardware logic, and a PCI unit that transfers data between the engine unit 23 and the PCI bus.

[0014] A FCU (Facsimile Control Unit) 18, USB (Universal Serial Bus) 19, and IEEE1394 (the Institute of Electrical and Electronics Engineers 1394) interface 21 are connected to the ASIC 16 via a PCI bus. An operation display unit 24 is directly connected to the ASIC 16. The MEM-C 17 is a local memory used as an image buffer for copying and a code buffer.

[0015] The AGP bus 15 is a bus interface for a graphics accelerator card proposed to speed up graphic processing, and increases the speed of the graphics accelerator card by directly accessing the MEM-P 12 at high throughput.

[0016] The FCU 18 is hardware that controls a facsimile function. Specifically, the FCU 18 is connected to a communication line N (e.g., a telephone line) and communicates with an external device using the facsimile function. For example, the FCU 18 receives image information from an external facsimile device via the communication line N. The image information is image data that indicates an image (e.g., an image of a document). The FCU 18 also transmits the image information to the external device via the communication line N.

[0017] As shown in Fig. 1, the FCU 18 is provided with a G3 terminal 18a and a G4 terminal 18b. The FCU 18 can transmit and receive image information Da through the G3 terminal 18a by G3 protocol communication. The FCU 18 can also transmit and receive image information Da through the G4 terminal 18b by G4 protocol communication. However, the interface used for transmitting and receiving the image information Da is not limited to the above example. For example, a configuration in which only one of the G3 terminal 18a and the G4 terminal 18b is provided may be used.

[0018] The HDD 25 of the controller 10 is a storage for storing image data, programs, font data, and forms, and stores program files of application software executed in the MFP 1.

[0019] 2 is a functional block diagram of a facsimile machine (MFP1) 100 according to this embodiment. For example, the above-mentioned CPU 11 executes a program, causing the MFP1 to function as the facsimile machine 100. As shown in FIG. 2, the facsimile machine 100 includes an acquisition unit 101, a conversion unit 102, a control unit 103, a display control unit 108, a fax application 109, a transmission unit 111, and a storage unit 112.

[0020] The display control unit 108, for example, causes the above-mentioned operation display unit 24 to display various screens. For example, the display control unit 108 causes screens such as an input screen for inputting destination information for fax transmission and a notification screen (see Figs. 5(a) to 5(c) described below). On the input screen, the user can specify destination information for fax transmission from an address book or transmission history, or can directly input destination information. The address book is information in which a plurality of destination names (such as company names) are registered in association with destination information such as fax numbers, and is stored in the storage unit 112.

[0021] Fig. 3(a) is an example of an address book in which destinations are registered. As shown in Fig. 3(a), the address book includes a registration ID, a registration name, a fax number, and an email address. The registration ID is identification information for identifying the destination. The registration name is the name of the destination, and is displayed on the operation display unit 24. The fax number in the address book is used when sending image information to the destination via a telephone line. The email address in the address book is used when sending image information to the destination via the Internet.

[0022] Each piece of information in the address book is registered in response to a user's operation via, for example, a registration screen displayed on the operation display unit 24. For example, in the specific example of Fig. 3(a), it is assumed that "Company A" is registered as the registration name of a destination with a registration ID of "1", "11111118" is registered as the fax number, and "A@aaa.com" is registered as the email address.

[0023] The transmission history is information in which a history of image information transmitted by the above-mentioned facsimile function is registered, and is stored in the storage unit 112. Specifically, the transmission history registers destination information of a destination to which image information was previously transmitted, and a date or date and time when the image information was transmitted.

[0024] FIG. 3(b) is an example of a transmission history. As shown in FIG. 3(b), the transmission history includes the transmission date and time and the fax number. The fax number in the transmission history is the fax number of the destination to which the image information was sent. The transmission date and time in the transmission history is the date and time when the image information was sent. For example, in the specific example of FIG. 3(b), it is assumed that image information was sent to the destination fax number "12345678" at 9:00 on July 15, 2019. The transmission history is automatically registered when image information is sent.

[0025] The acquisition unit 101 acquires image information. Specifically, the image information generated by the above-mentioned scan function is acquired by the acquisition unit 101. As described later, the image information acquired by the acquisition unit 101 is transmitted by the transmission unit 111 to an external device (e.g., another facsimile device).

[0026] The conversion unit 102 executes an OCR (Optical Character Reader) conversion process on the image information acquired by the acquisition unit 101. The conversion unit 102 executes the OCR conversion process, thereby converting the image information into document information. Specifically, an image indicated by the image information (for example, an image shown in FIG. 4(b) described below) may contain characters. In the OCR conversion process, characters contained in the image indicated by the image information are recognized, and character codes indicating the characters are generated. The document information is information including character codes generated from characters contained in the image indicated by the image information.

[0027] The control unit 103 is configured to realize the above-mentioned facsimile function, and includes a designation unit 104, an extraction unit 105, a determination unit 106, and a decision unit 107. The designation unit 104 designates destination information (e.g., a facsimile number) in response to a designation operation by a user. Destination Information Destination information is information for identifying a destination of image information, and is designated by a designation operation of a plurality of procedures. For example, the designation unit 104 designates destination information input via a fax transmission screen displayed by the display control unit 108. Note that the destination information may be an email address that is a destination of an Internet fax, an IP address or host name that is a destination of an IP fax, or a URL or path of a folder when sending a fax to a specific folder.

[0028] The designation operation includes an operation of selecting one of the destinations registered in the address book. For example, a configuration is conceivable in which button images corresponding to the destinations are displayed on the address book screen displayed by the display control unit 108, and the destination corresponding to the button image can be selected by touching one of the button images.

[0029] The storage unit 112 of the facsimile device 100 is provided with a destination storage unit 113. The destination storage unit 113 stores an address book. When one of the destinations registered in the address book is selected, the destination information of the destination is specified by the specification unit 104.

[0030] The designation operation also includes an operation of selecting any one of the destinations (destination information) registered in the transmission history. Specifically, the storage unit 112 is provided with a history storage unit 114. The history storage unit 114 stores the transmission history. When any one of the destination information registered in the transmission history is selected, the destination information is designated by the designation unit 104.

[0031] The designation operation also includes an operation of inputting destination information using an operation unit for inputting numerical values ​​(numeric keypad) (hereinafter, "direct input"). Note that the operation display unit 24 described above may be used as the operation unit for directly inputting destination information. However, an operation unit for inputting numerical values ​​may be provided separately from the operation display unit 24.

[0032] The extraction unit 105 extracts destination information from an image indicated by the image information. Specifically, an image indicated by the image information to be transmitted to a destination (for example, an image shown in FIG. 4(b) described later) may include destination information of the destination. However, the image usually includes a character string other than the destination information of the destination. The extraction unit 105 extracts a character string (for example, a number) indicating the destination information of the destination from the character string included in the image indicated by the image information. Specifically, the extraction unit 105 extracts a character string indicating the destination information of the destination from the document information generated by the above-mentioned OCR conversion process. Details of the above configuration will be described with reference to FIG. 4(a) and FIG. 4(b) described later.

[0033] The determination unit 106 determines whether or not the destination information specified by the designation unit 104 matches the destination information extracted by the extraction unit 105. That is, the determination unit 106 determines whether or not the destination information specified by the user's designation operation matches the destination information extracted from the image information. In the above configuration, if the user designates incorrect destination information through a designation operation, the determination unit 106 determines that the destination information does not match.

[0034] The determination by the determination unit 106 is executed by a determination process (see Sa13 in FIG. 6) described later. Furthermore, the display control unit 108 displays a notification screen (see FIGS. 5(a) to 5(c) described later) based on the determination result by the determination unit 106. The notification screen notifies the user that erroneous destination information has been specified.

[0035] The determining unit 107 can determine either the destination information specified by the designating unit 104 or the destination information extracted by the extracting unit 105. Specifically, on the above-mentioned notification screen, the user can select either the destination information specified by the designating unit 104 or the destination information extracted by the extracting unit 105. The determining unit 107 determines the destination information selected by the user. The transmitting unit 111 transmits the image information acquired by the above-mentioned acquiring unit 101 to a transmission destination specified from the destination information determined by the determining unit 107.

[0036] Fax application 109 is configured to enable various operations by a user to be accepted and to display various images on operation display unit 24. As shown in Fig. 2, fax application 109 is configured to include change unit 110. Change unit 110 changes the state of the notification screen depending on whether a designation operation is performed using the above-mentioned address book, whether a designation operation is performed using a history image, or whether destination information is directly input. Note that fax application 109 may be configured to include control unit 103.

[0037] Suppose that the notification screen is displayed in a uniform manner regardless of the procedure of the designation operation. In the above comparison, the inconvenience of not displaying the optimal notification screen may occur. According to the modification unit 110 of the present embodiment, the result image can be modified according to the procedure of the designation operation, and therefore, there is an advantage that the above-mentioned inconvenience is suppressed.

[0038] The storage unit 112 stores various types of information. For example, the storage unit 112 stores image information acquired by the acquisition unit 101 and document information generated by the conversion unit 102. The storage unit 112 also includes the above-mentioned destination storage unit 113 and history storage unit 114.

[0039] 4(a) and 4(b) are diagrams for explaining a configuration for extracting destination information from document information. When extracting destination information, the facsimile device 100 (extraction unit 105) first identifies a predetermined character string (hereinafter referred to as a "keyword") from the character string of the document information.

[0040] FIG. 4(a) is a diagram for explaining a specific example of the above-mentioned keywords. As shown in FIG. 4(a), the above keywords include a first keyword meaning a destination (recipient) and a second keyword meaning a fax number (recipient information). The above keywords are character strings that are likely to be located immediately before the recipient information. However, keywords not shown in FIG. 4(a) may also be used. The facsimile device 100 extracts the numeric string located immediately after the keyword (second keyword) as the recipient's recipient information.

[0041] Fig. 4(b) is a specific example of an image indicated by image information. In the specific example of Fig. 4(b), an image is assumed in which character strings are displayed in areas R1 to R3. Each character string in areas R1 to R3 is converted into a character code by the above-mentioned OCR conversion process. Furthermore, each character string in areas R1 to R3 is recognized as a separate character string (a set of characters).

[0042] In the specific example of FIG. 4(b), the character string in area R2 of each area R (1-3) includes the first keyword "Destination". In the above specific example, after identifying area R2, the facsimile device 100 extracts the character string "0312345677" located immediately after the second keyword "FAX" from the character string in area R2. Specifically, only numbers are extracted from the characters constituting the character string located immediately after the second keyword. In other words, symbols such as hyphens, parentheses, and colons are not extracted from the characters constituting the character string located immediately after the second keyword.

[0043] Fig. 5(a) to Fig. 5(c) are schematic diagrams of specific examples of each notification screen (GA to GC). When the determination unit 106 determines that the designated destination information designated by the designation unit 104 does not match the extracted destination information extracted by the extraction unit 105, the change unit 111 automatically displays each of the above notification screens in response to a designation operation based on the designated destination information, the extracted destination information, and the address book and transmission history stored in the storage unit 112. Details will be described later using the flowchart shown in Fig. 8.

[0044] Fig. 5(a) is a schematic diagram of the notification screen GA. In the specific example of Fig. 5(a), it is assumed that "Company A" is selected from among the destinations registered in the address book, and the destination information extracted from the image information matches the destination information of "Company B" registered in the address book.

[0045] That is, the specific example in Fig. 5(a) assumes a case where the user mistakenly selects "Company A" when he or she should have selected "Company B" from among the destinations registered in the address book. In the above case, the extraction unit 105 extracts the destination information "11111119" from the image information, and the determination unit 106 determines that the designated destination information "11111118" specified by the user's designation operation does not match the extracted destination information "11111119" extracted from the image information. Then, the change unit 111 searches the address book, determines that both the designated destination information and the extracted destination information are registered in the address book, and displays the notification screen GA.

[0046] As shown in Fig. 5(a), the notification screen GA displays a message indicating that the designated destination information specified by the user's designation operation does not match the extracted destination information extracted from the image information. Specifically, the notification screen GA displays a message indicating that the user selected "Company A" as the destination, but the image information the user is about to send will include destination information for "Company B." Note that the destination information for both "Company A" and "Company B" may be displayed on the notification screen GA.

[0047] As shown in Fig. 5(a), the notification screen GA displays button images Ba1, Ba2, and Bx. When the button image Ba1 is touched, the determination unit 107 determines the designated destination information designated by the user's designation operation, and the transmission unit 111 transmits the image information to the destination corresponding to the designated destination information. When the button image Ba2 is touched, the determination unit 107 determines the extracted destination information extracted from the image indicated by the image information, the change unit 110 changes the destination of the image information to the extracted destination information, and the transmission unit 111 transmits the image information to the destination corresponding to the extracted destination information. When the button image Bx is touched, the designation operation is cancelled, and the transmission of the image information is stopped.

[0048] Fig. 5(b) is a schematic diagram of the notification screen GB. In the specific example of Fig. 5(b), it is assumed that, among the destination information registered in the transmission history information, the destination information of the destination to which image information was transmitted on "July 15" is selected, and the destination information extracted from the image information matches the destination information of the destination to which image information was transmitted on "July 25" among the destination information stored in the history storage unit 114.

[0049] That is, the specific example of Fig. 5(b) assumes a case where the user mistakenly selects the destination information of the destination to which image information was sent on "July 15th" when the destination information of the destination to which image information was sent on "July 25th" should be selected from the destination information registered in the transmission history. In the above case, the extraction unit 105 extracts the destination information "12345679" from the image information, and the determination unit 106 determines that the designated destination information "12345678" designated by the user's designation operation does not match the extracted destination information "12345679" extracted from the image information. Then, the change unit 111 searches the transmission history, determines that both the designated destination information and the extracted destination information are registered in the transmission history, and displays the notification screen GB.

[0050] As shown in Fig. 5(b), the notification screen GB displays a message indicating that the designated destination information specified by the user through a designation operation does not match the extracted destination information extracted from the image information. Specifically, the destination information of the destination to which the image information was sent on "July 15th" was specified through a designation operation by the user, but the notification screen GB displays a message indicating that the destination information of the destination to which the image information was sent on "July 25th" is included in the image information to be sent this time. In addition, the destination information of the destination to which the image information was sent on "July 15th" and the destination information of the destination to which the image information was sent on "July 25th" are displayed on the notification screen GB.

[0051] As shown in Fig. 5(b), the notification screen GB displays button images Bb1, Bb2, and the above-mentioned button image Bx. When the button image Bb1 is touched, the determination unit 107 determines the designated destination information designated by the user's designation operation, and the transmission unit 111 transmits the image information to the destination corresponding to the designated destination information. When the button image Bb2 is touched, the determination unit 107 determines the extracted destination information extracted from the image indicated by the image information, the change unit 110 changes the destination of the image information to the extracted destination information, and the transmission unit 111 transmits the image information to the destination corresponding to the extracted destination information. When the button image Bx is touched, the designation operation is cancelled, and the transmission of the image information is stopped.

[0052] Fig. 5(c) is a schematic diagram of the notification screen GC. Destination information Destination information Destination information As shown in Fig. 5(c), a message is displayed to the effect that the designated destination information designated by the designation operation of directly inputting the user's fax number does not match the extracted destination information extracted from the image information. Also, the notification screen GC displays button images Bb1, Bb2, and Bx, similar to the notification screen GB described above.

[0053] Fig. 6 is a diagram for explaining a specific example of the operation of the facsimile device 100. As shown in Fig. 6, the fax application 109 receives an instruction to execute fax transmission from a user (Sa1). Specifically, after placing an original in a predetermined position, the user selects (or directly inputs) the destination address information by the above-mentioned designation operation, and presses a start key or the like to instruct execution of fax transmission. The fax application 109 transmits an instruction to execute fax transmission to the control unit 103 (Sa2). Upon receiving the above instruction, the control unit 103 transmits an instruction to execute document reading to the acquisition unit 101.

[0054] When an instruction to read a document is given, the acquisition unit 101 executes a reading process (Sa4) and generates (acquires) image information from the document set by the user. The acquisition unit 101 stores the image information generated from the document in the storage unit 112 (Sa5). When the storage unit 112 stores the image information, it notifies the acquisition unit 101 of the fact (Sa6). Furthermore, the acquisition unit 101 notifies the control unit 103 of the fact that the image information has been stored (Sa7).

[0055] When notified that the image information has been stored, the control unit 103 transmits an instruction to execute OCR conversion processing to the conversion unit 102 (Sa8). Upon receiving the above instruction, the conversion unit 102 requests the image information from the storage unit 112 (Sa9). In response to the above request, the storage unit 112 transmits the image information stored in the above-mentioned step Sa5 to the conversion unit 102 (Sa10).

[0056] When the conversion unit 102 receives the image information, the conversion unit 102 executes an OCR conversion process (Sa11) on the image information. After executing the OCR conversion process, the conversion unit 102 transmits the document information (OCR result) generated by the OCR conversion process to the control unit 103 (Sa12).

[0057] When the control unit 103 receives the document information, it executes an extraction process (Sa13). Specifically, it uses the above-mentioned keyword (see FIG. 4(a)) to extract a character string indicating destination address information from the character string included in the document information. The control unit 103 also executes a determination process (Sa14). In the determination process, it is determined whether the address information selected in the above-mentioned step Sa1 (address information specified by a user's specification operation) matches the address information extracted in the extraction process, and it is determined whether a notification screen is to be displayed, and if a notification screen is to be displayed, which of the notification screens GA to GC is to be displayed. Details will be described later using the flowchart shown in FIG. 8.

[0058] Depending on the result of the above-mentioned determination process, the process to be executed thereafter changes. Specifically, if the determination process determines that the destination information specified by the user's designation operation matches the destination information extracted in the extraction process, the image information is then transmitted to the destination specified by the designation operation (matching the destination information extracted in the extraction process). On the other hand, if it is determined that the destination information does not match, the process from step Sa16 onwards, which will be described later, is executed. In the specific example of FIG. 6, it is assumed that the determination process determines that the destination information does not match.

[0059] If it is determined that the destination information specified by the user's specification operation does not match the destination information extracted by the extraction process, the control unit 103 notifies the fax application 109 of that effect (Sa15). In response to the above notification, the fax application 109 displays the above-mentioned notification screens (GA to GC) to the user (Sa16).

[0060] Assume that button image Ba1, button image Ba2 (see FIG. 5(a) above) or button image Bb1, button image Bb2 (see FIG. 5(b) and FIG. 5(c) above) on the notification screen is touched (Sx1). In the above case, fax application 109 determines either destination information designated by the user's designation operation or destination information extracted in the extraction process according to touched button image B, and notifies control unit 103 of the determined destination information (Sx2). Control unit 103 notifies transmission unit 111 of the notified destination information and instructs it to execute transmission (Sx3).

[0061] When the transmitting unit 111 receives the instruction to execute transmission, it requests image information from the memory unit 112 (Sx4). In response to the above request, the memory unit 112 transmits the image information stored in the above-mentioned step Sa5 to the transmitting unit 111 (Sx5). When the transmitting unit 111 receives the image information, it executes a transmission process (Sx6). In the above transmission process, the image information is transmitted to the destination specified by the destination information notified in step Sx3. Thereafter, the transmitting unit 111 notifies the control unit 103 that the transmission process has ended (Sx7).

[0062] On the other hand, when the above-mentioned button image Bx among the button images B on the notification screen displayed in step Sa16 is touched (Sy1), the fax application 109 notifies the control unit 103 of a stop instruction (Sy2). Upon receiving the stop instruction, the control unit 103 executes a stop process (Sy3). By the above stop process, the image information is not transmitted and each of the above-mentioned steps is canceled (the generated information is discarded).

[0063] 7 is a flowchart of the extraction process (Sa13 in FIG. 6 above). When the extraction process starts, the facsimile device 100 sets the area number N to an initial value of "1" (S10). Specifically, as described above with reference to FIG. 4(b), the image indicated by the image information may have multiple areas R containing character strings. The facsimile device 100 assigns an area number N to each of the areas R.

[0064] After setting the area number N to an initial value of "1", the facsimile device 100 searches the area R of the area number N (S11) and determines whether or not a first keyword meaning a destination (for example, the character string "to") is included in the area R (S12). If it is determined that the first keyword meaning a destination is included in the area R (S12: Yes), the facsimile device 100 determines whether or not a second keyword meaning destination information (fax number) is included in the area R (S13).

[0065] If it is determined that the second keyword is included in the region R (S13: Yes), the facsimile device 100 extracts the numeric string located immediately after the second keyword as destination information (S14). After extracting the destination information, the facsimile device 100 ends the extraction process.

[0066] The facsimile device 100 increments the area number N (S16) and repeatedly executes steps S11 to S13 until the above-mentioned steps S12 and S13 return "Yes." However, when the search of all areas R is completed (S15: No), the facsimile device 100 may end the extraction process without extracting destination information.

[0067] FIG. 8 is a flowchart of the determination process (Sa14 in FIG. 8). When the determination process starts, the determination unit 106 acquires extracted destination information extracted from the image information and designated destination information designated by the user (S21). Thereafter, the determination unit 106 judges whether the extracted destination information acquired in step S21 matches the designated destination information (S22). If the extracted destination information matches the designated destination information (S22: Yes), the determination unit 106 judges not to display the notification screen (S23). Note that if the determination in step S22 is "Yes," the destination corresponding to the designated destination information naturally matches the destination corresponding to the extracted destination information. The transmission unit 111 transmits the image information by referring to either the designated destination information or the extracted destination information.

[0068] If the extracted destination information does not match the specified destination information (S22: No), the change unit 111 judges whether the specified destination information is specified from a destination registered in the address book (S24). Specifically, if the specified destination information is registered in the address book, the change unit 111 judges that the specified destination information is specified from a destination registered in the address book.

[0069] The configuration for determining whether or not the designated destination information is designated from a destination registered in the address book can be modified as appropriate. For example, when the user designates the destination information from the address book, a modified example is conceivable in which the display control unit 108 stores designation method information indicating that the user has designated the destination information. The display control unit 108 stores the designation method information in, for example, the RAM 12b.

[0070] In the above modified example, when the designation method information indicates that the destination information was designated from the address book, the change unit 111 determines that the designated destination information acquired in step S21 was designated from a destination registered in the address book. On the other hand, when the designation method information does not indicate that the destination information was designated from the address book, the change unit 111 determines that the designated destination information acquired in step S21 was not designated from a destination registered in the address book.

[0071] When the change unit 111 determines that the specified destination information acquired in step S21 is specified from a destination registered in the address book (S24: Yes), it determines whether the extracted destination information is registered in the address book (S25). When the change unit 111 determines that the extracted destination information is registered in the address book (S25: Yes), it determines that the notification screen GA should be displayed (S26) and ends the determination process. On the other hand, when the change unit 111 determines that the extracted destination information is not registered in the address book (S25: No), it determines that the notification screen GC should be displayed (S27) and ends the determination process.

[0072] When determining that the designated destination information is not designated from a destination registered in the address book (S24: No), the change unit 111 determines whether the designated destination information is designated from a transmission history (S28). Specifically, when the designated destination information is registered in the transmission history, it is determined that the designated destination information is designated from a transmission destination registered in the transmission history.

[0073] The configuration for determining whether the specified destination information is specified from the transmission history can be modified as appropriate. For example, a modified example is possible in which, when the user specifies the destination information from the transmission history, the display control unit 108 stores the specification method information indicating that fact. The display control unit 108 stores the specification method information in, for example, the RAM 12b.

[0074] In the above modification, when the designation method information indicates that the destination information was designated from the transmission history, the change unit 111 determines that the designated destination information acquired in step S21 was designated from a destination registered in the transmission history. On the other hand, when the designation method information does not indicate that the destination information was designated from the transmission history, the change unit 111 determines that the designated destination information acquired in step S21 was not designated from a destination registered in the transmission history.

[0075] When the change unit 111 determines that the specified destination information is not specified from the transmission history (S28: No), it determines that the notification screen GC is to be displayed (S27). On the other hand, when the change unit 111 determines that the specified destination information is specified from the transmission history (S28: Yes), it determines whether the extracted destination information acquired in step S21 is registered in the transmission history (S29). When the change unit 111 determines that the extracted destination information is not registered in the transmission history (S29: No), it determines that the notification screen GC is to be displayed (S27). On the other hand, when the change unit 111 determines that the extracted destination information is registered in the transmission history (S29: Yes), it determines that the notification screen GB is to be displayed (S30).

[0076] In this way, when the extracted destination information does not match the specified destination information, if the specified destination information is designated by a destination registered in the address book and the extracted destination information is registered in the address book, the change unit 111 determines to display the notification screen GA. On the other hand, if the specified destination information is designated by a destination registered in the transmission history and the extracted destination information is registered in the transmission history, the change unit 111 determines to display the notification screen GB, and otherwise displays the notification screen GC.

[0077] The change unit 111 may determine to display the notification screen GA if the specified destination information satisfies either of the two conditions that the specified destination information is specified from a destination registered in the address book (step S22) or the extracted destination information is registered in the address book (step S24). In this case, on the notification screen GA, for destination information registered in the address book among the specified destination information and the extracted destination information, the registered name corresponding to the destination information may be displayed, and for destination information not registered in the address book, the destination information may be displayed.

[0078] Furthermore, the change unit 111 may determine to display the notification screen GB if the specified destination information satisfies either of the two conditions that the specified destination information is specified from a destination registered in the transmission history (step S28) or the extracted destination information is registered in the transmission history (step S29). In this case, the notification screen GB may display the transmission date and time corresponding to the destination information registered in the transmission history among the specified destination information and the extracted destination information, and may display the destination information not registered in the address book.

[0079] The device for executing each of the above processes can be changed as appropriate. Each of the above functions (such as the determination unit) can be realized by one or more processing circuits. Here, the term "processing circuit" in this specification includes a processor programmed to execute each function by software, such as a processor implemented by an electronic circuit, and devices such as an ASIC (Application Specific Integrated Circuit), a DSP (digital signal processor), an FPGA (field programmable gate array), and a conventional circuit module designed to execute each of the above-described functions.

[0080] <Modification> The above embodiment can be modified in various ways, and specific modifications will be described below.

[0081] In the above embodiment, the method of extracting the character string of the destination address information from the document information is not limited to the above example. For example, in the extraction process of the above embodiment, the destination address information may not be extracted. In the above case, any of the numeric strings included in the document information may be extracted as the destination address information.

[0082] In the above modified example, a configuration may be adopted in which, from among the numeric strings contained in the document information, a numeric string similar to the destination information specified by the designation operation is preferentially extracted. For example, assume that the document information includes a plurality of numeric strings (hereinafter, "target destination information"). In the above case, a configuration is preferred in which, from among the plurality of target destination information, the target destination information most similar to the destination information specified by the designation operation (hereinafter, "designated destination information") is extracted.

[0083] Specifically, it is assumed that the designated destination information has M digits. In the above cases, it is determined whether or not each digit of the designated destination information matches each digit of the target destination information. A similarity of "1" (the highest similarity) is assigned to target destination information in which each of M-1 digits matches the designated destination information. Similarly, a similarity of "2" is assigned to target destination information in which each of M-2 digits matches the designated destination information, a similarity of "3" is assigned to target destination information in which each of M-3 digits matches the designated destination information, and so on. A similarity of "M" (the lowest similarity) is assigned to target destination information in which all digits do not match the designated destination information. In the above configuration, the target destination information with the highest similarity is extracted from each of the target destination information.

[0084] <Summary of the functions and effects of the embodiment> <First aspect> The facsimile machine of this aspect includes a designation unit (104) that designates destination information in response to a designation operation by a user, an extraction unit (105) that extracts destination information from an image indicated by image information, a determination unit (106) that determines whether the destination information designated by the designation unit matches the destination information extracted by the extraction unit, and a display control unit (108) that displays a notification screen that displays the result of the determination. According to the above-described aspect, the result of the determination is notified to the user.

[0085] <Second aspect> The facsimile machine of this aspect includes a change unit (110) that changes the mode of the notification screen (GA to GC) depending on whether the designation operation is performed in a first procedure (procedure using an address book) or a second procedure (procedure using a history image) that is different from the first procedure. According to the above-described aspect, an appropriate notification screen can be displayed.

[0086] <Third aspect> The facsimile machine of this embodiment includes a destination storage unit (113) that stores the name of the destination in association with the destination information of the destination, and when a designation operation is performed in the first step, the notification screen displays the name of the destination corresponding to the destination information designated by the designation unit in response to the designation operation, and the name of the sender corresponding to the destination information extracted by the extraction unit (see FIG. 5(a)). According to this embodiment, the effect of being able to display an appropriate notification screen is particularly remarkable.

[0087] <Fourth aspect> The facsimile machine of this embodiment is equipped with a history storage unit (114) that stores history information specifying the past date on which image information was transmitted in association with the destination information of the transmission destination to which the image information was transmitted, and when a designation operation is performed in the second step, the notification screen displays the past date on which image information was transmitted to the transmission source corresponding to the destination information designated in the designation operation, and the past date on which image information was transmitted to the transmission source corresponding to the destination information extracted by the extraction unit (see FIG. 5(b)). According to the above-described embodiment, the effect of being able to display an appropriate notification screen is particularly remarkable.

[0088] <Fifth aspect> The control method of this embodiment is a control method realized by a computer, which includes a step of designating destination information in response to a designation operation by a user (Sa2 in FIG. 6), a step of extracting destination information from an image indicated by image information (Sa13 in FIG. 6), a step of determining whether the designated destination information matches the extracted destination information (Sa14 in FIG. 6), and a step of displaying a notification screen displaying the result of the determination (Sy2 in FIG. 6). According to the above-described embodiment, the same effects as those of the first embodiment can be achieved.

[0089] <Sixth aspect> The program of this aspect is characterized by causing a computer to execute each step of the control method of the above-mentioned fifth aspect. In the above-mentioned present aspect, the same effects as those of the above-mentioned first aspect are achieved. [Explanation of symbols]
