Embodiments for Carrying Out the Invention

[0009] Hereinafter, an image reading apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an electrical configuration of the image reading apparatus according to an embodiment of the present invention.

[0010] The image reading apparatus 1 includes a control unit 11, an input reception unit 12, an image reading unit 13, a storage device 14, a communication unit 15, an external storage device connection unit 160, an automatic document feeder 17, and the like. The input reception unit 12 includes hard keys such as a decision key and a start key for performing determination operations of various operations and settings, and a display unit 121. The display unit 121 is composed of an LCD (Liquid Crystal Display) or the like, and displays an operation screen, a message, and the like. The display unit 121 may be integrally configured with a touch panel.

[0011] The image reading unit 13 includes, for example, a scanner, and reads the image of a document placed on the platen glass to acquire image data. The automatic document feeder 17 can hold a plurality of documents, and conveys the placed documents one by one to the reading position of the image reading unit 13 by a conveying roller. The storage device 14 is a large-capacity storage device composed of an SSD or an HDD that stores image data, various programs, data tables, and the like. The communication unit 15 is composed of a communication module or the like, and transmits and receives various data to and from an external device via a network.

[0012] The external storage device connection unit 160 is a socket (interface of a slot or a USB port) to which the external storage device 16 is connected. The external storage device 16 is a storage that can store large-capacity data, and is, for example, an SD (Secure Digital) card, a USB (Universal Serial Bus) memory, or the like. The external storage device 16 is used by being mounted on the external storage device connection unit 160. The control unit 111 described later stores various data in the storage device 14 or the external storage device 16 (external storage medium). The storage device 14 is an example of the storage unit in the claims.

[0013] The control unit 11 is composed of a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The processor is a CPU (Central Processing Unit), an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), or the like. The control unit 11 functions as a control unit 111, a multi-crop unit 112, and a document type discrimination unit 113 by the processor executing a control program stored in the ROM or the like. Note that each of the above units of the control unit 11 may be composed of a hard circuit without depending on the operations based on the control program.

[0014] The control unit 111 is in charge of overall operation control of the image reading apparatus 1.

[0015] When the image reading unit 13 reads an image including a plurality of originals, the multi-crop unit 112 performs edge detection of the image to obtain the position information of each original, cuts out the image, and obtains an original unit image (cropped image). For example, when the image reading unit 13 reads a plurality of passports, a plurality of credit cards, etc. at once, by creating cropped images of each passport and each credit card by the multi-crop unit 112, the user can obtain each image by one scan operation. This multi-crop function uses known technology and detailed description thereof is omitted.

[0016] The original type discrimination unit 113 performs OCR (Optical Character Recognition) processing etc. on the cropped image, and discriminates the type of the original (passport, credit card, receipt, invoice, etc.) corresponding to the cropped image based on the obtained character recognition result.

[0017] Furthermore, the control unit 111 controls to transmit the cropped image to the transmission destination (external device or cloud) received by the input reception unit 12, or to store the cropped image in the external storage device 16. Also, the control unit 111 controls to transmit or store the cropped image to a predetermined transmission destination or storage destination according to the type of the original of the cropped image discriminated by the original type discrimination unit 113.

[0018] <Embodiment 1> First, a first embodiment of the management process of the cropped image by the image reading apparatus 1 will be described using a flowchart and an example of a display screen. FIG. 2 is a flowchart showing the first embodiment of the management process of the cropped image. FIG. 3 is an example of the home screen of the display unit 121. In each of the following embodiments, the storage destination of the cropped image is described as the external storage device 16, but instead, the storage device 14 and its internal folders may be used.

[0019] When the control unit 111 causes the display unit 121 to display the home screen G1 (Fig. 3), if the user touches the scan button 21, a scan start instruction is received by the input reception unit 12 via the touch panel. The control unit 111 causes the display unit 121 to display a scan image save destination setting screen G2 as shown in Fig. 4 in accordance with the scan start instruction.

[0020] Here, when the external storage device 16 is not attached to the external storage device connection unit 160, the control unit 111 displays the send button 22 and the USB save button 23, and causes the input reception unit 12 to receive an instruction based on the operation of the send button 22 and the USB save button 23 via the touch panel.

[0021] Note that when the external storage device 16 is not attached to the external storage device connection unit 160, the control unit 111 displays the USB save button 23 in light gray (gray out) or the like, and causes the input reception unit 12 not to receive an instruction based on the operation of the USB save button 23 via the touch panel.

[0022] When the save destination setting screen G2 is being displayed and the user touches the send button 22, the input reception unit 12 receives a send instruction to send the image data acquired by the image reading unit 13 scanning the document to an external device or cloud storage or the like via the Internet or the like (S11).

[0023] On the other hand, when the save destination setting screen G2 is being displayed and the user touches the USB save button 23, the input reception unit 12 receives a send instruction to save the image data acquired by the image reading unit 13 scanning the document to the external storage device 16 such as a USB storage (S11).

[0024] Note that when the storage destination setting screen G2 is displayed, the control unit 111 receives, via the input reception unit 12 based on an operation by the user, an instruction to select whether to (i) transmit all the cropped images to a specified transmission destination or save them to a storage destination (batch), (ii) transmit or save each cropped image to a different transmission destination or storage destination (individual), or (iii) transmit or save each document type to a different transmission destination or storage destination (by document type). In Embodiment 1, it is assumed that based on the user's operation of the radio button 21a, the control unit 111 receives an instruction to (i) transmit or save all the cropped images to the specified transmission destination or storage destination (batch).

[0025] In S11, when a transmission instruction is received, the control unit 111 causes the display unit 121 to display a selection screen G3 for the transmission destination of the image data. The storage device 14 stores a transmission destination address book, and the control unit 111 causes the display unit 121 to display transmission destination candidates read from the transmission destination address book. FIG. 5 is an example of a selection screen G3 for displaying transmission destination candidates. When the user touches the display portion of a desired transmission destination candidate among the transmission destination candidates displayed on the selection screen G3 and then touches the OK button B1, an instruction to select the transmission destination candidate displayed in the touched portion is received by the input reception unit 12 (S12). The control unit 111 sets the received transmission destination candidate as the transmission destination and causes a check mark 24 to be displayed at the selected transmission destination.

[0026] Also, when transmitting to a new transmission destination, on the selection screen G3, the user touches the new transmission destination button 251. When a new transmission destination setting instruction is received by the input reception unit 12 based on the touch operation on the new transmission destination button 251, the control unit 111 causes the display unit 121 to display a new transmission destination input screen G4 shown in FIG. 6 as an example. When an e-mail address, a URL of cloud storage, etc. is received by the input reception unit 12 as a new transmission destination based on the user's touch panel or input reception unit 12 operation when the new transmission destination input screen G4 is displayed, the control unit 111 sets the received transmission destination candidate as the transmission destination.

[0027] On the other hand, when the user touches the USB save button 23 while the save destination setting screen G2 shown in FIG. 4 is being displayed, the control unit 111 causes the display unit 121 to display a save location selection screen G5 showing a storage area (such as a folder) in the external storage device 16 connected to the external storage device connection unit 160, as shown in FIG. 7 for example. When this save location selection screen G5 is being displayed, if the user touches the display portion of a desired folder from, for example, the save destination candidates displayed on the save location selection screen G5, and then touches the OK button B2, an instruction to select the folder displayed at the touched portion as the save destination is received by the input reception unit 12 (S12). The control unit 111 sets the received folder as the save destination and makes the display form of the folder display portion different as the selected save destination.

[0028] After the transmission destination or save destination is set in S12, the control unit 111 causes the display unit 121 to display a scan setting screen G6 as shown in FIG. 8 for example. When the user touches the multi-crop button 25 on the scan setting screen G6 and a multi-crop execution instruction is received by the input reception unit 12 via the touch panel, the control unit 111 sets the multi-crop function to on (S13).

[0029] Subsequently, the control unit 111 causes the display unit 121 to display a scan execution screen G7 as shown in FIG. 9 for example. When the user touches the start button 26 and a scan execution instruction is received by the input reception unit 12 via the touch panel, the control unit 111 causes the image reading unit 13 to scan a plurality of originals placed on the platen at once and acquires a scan image including the original images of each original (S14).

[0030] Here, the image reading unit 13 is provided with, for example, an optical known original detection sensor (not shown) that detects whether or not an original is placed on the platen glass. If the original detection sensor detects that no original is placed on the platen glass, the control unit 111 may cause the display unit 121 to display an error message. In this case, the control unit 111 does not cause the image reading unit 13 to perform the original reading operation.

[0031] Further, the automatic document feeder 17 may be provided with, for example, a known optical document presence / absence detection sensor (not shown) that detects whether or not a document is set on the automatic document feeder 17. When it is detected by the document presence / absence detection sensor that a document is set on the automatic document feeder 17 and it is detected by the document detection sensor that a document is placed on the platen glass, the control unit 111 may cause an error message to be displayed on the display unit 121. In this case, the control unit 111 does not cause the document reading operation by the image reading unit 13 to be performed.

[0032] After the document placed on the platen is scanned by the image reading unit 13, the multi-crop unit 112 performs edge detection on the scanned image by a known edge detection technique, cuts out each rectangular image formed by the detected edges from the scanned image, and acquires a crop image indicating the document image of each document for each document (S15).

[0033] Here, the multi-crop unit 112 may impose a limit on the number of crop images acquired from one scanned image. For example, when the maximum scan size of the image reading apparatus 1 is A3 size, the multi-crop unit 112 limits the number of crop images acquired from the scanned image to a maximum of 16. Also, when the maximum scan size of the image reading apparatus 1 is A4 size, the multi-crop unit 112 limits the number of crop images acquired from the scanned image to a maximum of 10. Note that the limited number of crop images is not limited to this.

[0034] Further, the minimum document from which the multi-crop unit 112 acquires a crop image may be a document image of a document having a width of, for example, 210 mm. Furthermore, a limit may be provided such that the multi-crop unit 112 acquires a crop image only from the document images obtained by reading with an interval of, for example, 15 mm or more between the documents placed on the platen glass. That is, in this case, the multi-crop unit 112 does not acquire a crop image from the document images obtained by reading with an interval of, for example, less than 15 mm between the documents placed on the platen glass.

[0035] After S15, the control unit 111 transmits each acquired crop image to the transmission destination selected in S12 or saves it to the save destination (S16). Here, although the USB save button 23 was selected in process S11, if the external storage device 16 is not attached to the image reading device 1 at the stage of process S16, the control unit 111 may display an error message on the display unit 121 (excluding the case where the USB save button 23 is grayed out and the user's operation is not accepted as described above).

[0036] FIG. 10 is a diagram showing an example of an error message screen. While the external storage device 16 (USB memory) is not attached, the control unit 111 grays out the OK button 27 and sets the state such that the input reception unit 12 does not accept the user's operation. When the user attaches the external storage device 16 to the image reading device 1 and the control unit 111 recognizes it, the control unit 111 normally displays the OK button 27 and sets the state such that the input reception unit 12 accepts the user's operation. When the external storage device 16 is accepted as the save destination by the input reception unit 12 by the touch operation of the OK button 27 by the user, the control unit 111 saves the crop image in the external storage device 16.

[0037] As described above, since the image reading unit 13 reads a plurality of originals at once, the multi-crop unit 112 cuts out crop images for each original from the scanned image, and the control unit 111 transmits all the crop images to the selected transmission destination or saves them to the save destination, a plurality of crop images can be processed collectively. Therefore, the labor of the user when processing a plurality of crop images collectively can be saved.

[0038] <Embodiment 2> Next, a second embodiment of the management process of the crop image by the image reading device 1 will be described using a flowchart and an example of a display screen. FIG. 11 is a flowchart showing the second embodiment of the management process of the crop image.

[0039] In Embodiment 1, the case where all the crop images cut out from the scanned image obtained by a single manuscript reading are transmitted to the designated destination or all the crop images are saved to the designated storage destination was described. However, in Embodiment 2, each crop image is transmitted or saved to the designated transmission destination and storage destination for each crop image. In the flowchart shown in FIG. 11, the same processes as those described in Embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted or simplified.

[0040] In a state where the storage destination setting screen G2 is displayed, based on an operation by the user, an instruction to transmit or save the image data obtained by the image reading unit 13 scanning the manuscript is received by the input reception unit 12 (S11). When this storage destination setting screen G2 is displayed, in Embodiment 2, based on an operation of the radio button 21b by the user (see FIG. 12), it is assumed that the control unit 111 has received an instruction to (ii) transmit to different transmission destinations or save to storage destinations for each crop image (individual).

[0041] In the second embodiment, in S11, when an instruction to transmit or save is received, the control unit 111 displays the scan setting screen G6, and when the input reception unit 12 receives a multi-crop execution instruction, the multi-crop function is set to on (S13). Subsequently, the control unit 111 performs the processes of S14 and S15 to read a plurality of manuscripts and obtain crop images of each manuscript.

[0042] Next, the case where a transmission instruction has been received in S11 will be described. After the process of S15, the control unit 111 causes the display unit 121 to display an image-by-image transmission destination setting screen G9 shown in FIG. 13. In the image-by-image transmission destination setting screen G9, the control unit 111 displays each acquired crop image as a thumbnail and further displays each transmission destination candidate. The thumbnail group 31 is each image obtained by reducing the crop image. When the user touches, for example, a desired thumbnail 32 from the thumbnail group 31 and further touches an image indicating a desired transmission destination from the images indicating the transmission destination candidates, the control unit 111 receives, via the input reception unit 12, an image selection instruction for selecting the crop image indicated by the touched thumbnail 32 and a transmission destination selection instruction for selecting the desired transmission destination as the transmission destination of the crop image. The control unit 111 receives, via the input reception unit 12, an image selection instruction for selecting this crop image and a transmission destination selection instruction for selecting a transmission destination according to the operation by the user for each thumbnail 32 of the thumbnail group 31. The control unit 111 causes a check mark to be displayed on the selected thumbnail 32 for the transmission destination.

[0043] After that, when the user touches the new transmission destination button 251 and a confirmation instruction is received by the input reception unit 12, the control unit 111 performs, for each crop image, a process of associating and storing the crop image indicated by the image selection instruction received at this time with the transmission destination indicated by the transmission destination selection instruction (S21).

[0044] Subsequently, when the user touches the transmission button 28 and a transmission execution instruction is received by the input reception unit 12, the control unit 111 transmits each of the selected crop images to the selected respective transmission destinations (S22).

[0045] On the one hand, in S11, when a save instruction has been received, after the process of S15, the control unit 111 causes the display unit 121 to display an image-by-image transmission destination setting screen G10 shown in FIG. 14. In the image-by-image transmission destination setting screen G10, the control unit 111 causes a thumbnail group 31 showing each of the acquired crop images to be displayed, and further causes an image showing a save destination candidate to be displayed. When the user touches, for example, a desired thumbnail 32 from the thumbnail group 31 and further touches an image showing a desired save destination from the image showing the save destination candidate, the control unit 111 receives, via the input reception unit 12, an image selection instruction for selecting the crop image indicated by the touched thumbnail 32 and a save destination selection instruction for selecting the desired save destination as the save destination of the crop image. The control unit 111 receives, via the input reception unit 12, an image selection instruction for selecting this crop image and a save destination selection instruction for selecting a save destination according to the operation by the user for each thumbnail 32 of the thumbnail group 31. The control unit 111 causes a check mark to be displayed on the thumbnail 32 for which the save destination has been selected.

[0046] After that, when the user touches the new save destination button 29 and a confirmation instruction is received by the input reception unit 12, the control unit 111 performs, for each crop image, a process of associating and storing the crop image indicated by the image selection instruction received at this time with the save destination indicated by the save destination selection instruction (S21).

[0047] Subsequently, when the user touches the save button 30 and a save execution instruction is received by the input reception unit 12, the control unit 111 saves each of the selected crop images to the selected respective save destinations (S22).

[0048] <Embodiment 3> Next, a third embodiment of the management process of the cropped images by the image reading apparatus 1 will be described using a flowchart and an example of a display screen. FIG. 15 is a flowchart showing the third embodiment of the management process of the cropped images. In the third embodiment, the document type of the cropped image is discriminated, and it is transmitted to a predetermined destination or saved to a save destination for each document type. In FIG. 15, the same processes as those described in the first embodiment or the second embodiment are denoted by the same reference numerals, and the description thereof is omitted or simplified.

[0049] In a state where the save destination setting screen G2 is being displayed, based on an operation by the user, an instruction to transmit or save the image data obtained by scanning the document by the image reading unit 13 is received by the input reception unit 12 (S11). In the third embodiment, at the time of displaying this save destination setting screen G2, based on an operation of the radio button 21c by the user (see FIG. 16), it is assumed that the control unit 111 has received an instruction to transmit to a different transmission destination or save to a save destination for each document type (by document type).

[0050] Thereafter, the processes of S13 to S15 are performed in the same manner as in the second embodiment. In the third embodiment, when the cropped images of each document are obtained by the process of S15, the document type discrimination unit 113 discriminates the document type of each cropped image (S31). The document type discrimination unit 113 recognizes characters from the cropped image using, for example, an optical character recognition processing technique (OCR: Optical Character Recognition), and discriminates the document type from the recognized characters. Here, in order to facilitate the discrimination of the document type, the storage device 14 stores in advance word candidates (for example, "Credit Cart", "Bank Card", "invoice", "receipt", etc.) that are materials for discrimination. When the document type discrimination unit 113 determines that the characters recognized by the OCR technique have a character string that matches the word candidate, the document type associated with the word candidate is discriminated as the document type of the cropped image that was the target of the character recognition.

[0051] Subsequently, the control unit 111 causes the display unit 121 to display a document type display screen G11 showing thumbnails of the cropped images for each document type determined by the document type determination unit 113 (S32). Hereinafter, the case where a transmission instruction has been received in S11 will be described. FIG. 17 is a diagram showing an example of the document type display screen G11. In area 41 on the document type display screen G11, a thumbnail of the cropped image determined by the document type determination unit 113 to be a credit card is displayed. The transmission destination for each document type is, for example, a transmission destination that has been previously input by the user for each document type through the operation of the input reception unit 12 and set by the control unit 111. FIG. 17 shows that "credit@aaa.com" is set as the transmission destination for all the cropped images determined to be credit cards. In area 42, a thumbnail of the cropped image determined by the document type determination unit 113 to be a bank card is displayed, and the control unit 111 indicates that "bank@aaa.com" is set as the transmission destination for this cropped image.

[0052] If there is a cropped image for which the document type determination unit 113 cannot determine the document type, the control unit 111, for example, causes the thumbnail 43a of that cropped image to be displayed in area 43 indicating that the document type is unknown. When the user touches the thumbnail 43a and touches the transmission destination change button 44, and when the input reception unit 12 receives the cropped image indicated by the thumbnail 43a and a transmission destination change instruction, the control unit 111 displays the new transmission destination input screen G4 shown in FIG. 6. When the new transmission destination input screen G4 is displayed, when an e-mail address, a URL of cloud storage, etc. are received by the input reception unit 12 as a new transmission destination based on the operation of the touch panel by the user or the input reception unit 12, the control unit 111 sets the received transmission destination candidate as the transmission destination for the selected cropped image. Thereafter, the control unit 111 causes the display unit 121 to display the document type display screen G11 again. Then, when the user touches the transmission button 25 and a transmission execution instruction is received by the input reception unit 12 when the document type display screen G11 is displayed, the control unit 111 transmits each cropped image to each transmission destination set for each document type (S33).

[0053] On the other hand, when a save instruction is received at S11, after the process of S15, the control unit 111 causes the display unit 121 to display a document type display screen G12 as shown in FIG. 18 at S32. The save destination for each document type is, for example, a save destination that has been previously input for each document type by the user through an operation of the input reception unit 12 and set by the control unit 111. In FIG. 18, in area 41 of the document type display screen G12, each crop image determined to be a credit card is displayed, and all of these crop images indicate that "USB memory A folder" is set as the save destination. Also, in area 42, a thumbnail of a crop image that the document type determination unit 113 has determined to be a bank card is displayed, and this crop image indicates that "USB memory B folder" is set as the save destination.

[0054] If there is a crop image for which the document type determination unit 113 cannot determine the document type, the control unit 111, for example, causes a thumbnail 43a of that crop image to be displayed in an area 43 indicating that the document type is unknown. The save destination for a crop image with an unknown document type is, for example, a save destination that has been previously input for each document type by the user through an operation of the input reception unit 12 and set by the control unit 111. On the document type display screen G12, it is shown that "USB memory C folder" is set as the save destination for the crop image for which the document type has been determined to be unknown. Then, when the user touches the save button 250 and a save execution instruction is received by the input reception unit 12 during the display of the document type display screen G12, the control unit 111 saves each crop image to the respective save destination set for each document type (S33).

[0055] The present invention is not limited to the configuration of the above-described embodiment, and various modifications are possible. Also, in the above-described embodiment, the configuration and processing shown by the above-described embodiment using FIGS. 1 to 18 are merely one embodiment of the present invention, and the present invention is not intended to be limited to such configuration and processing.
