[Embodiment 1]
Hereinafter, Embodiment 1 of the present invention will be described. In the present embodiment, when the image reading unit 150 starts reading the image of the paper, the image based on the generated image data is displayed on the operation panel 130 as a preview. Here, if an abnormality such as a paper jam occurs and the reading operation is interrupted, the preview display is also stopped. Then, when the user performs an operation of resolving an abnormality such as a paper jam and restarting image reading, reading by the image reading unit 150 is restarted. At that time, the image of the last paper that has been scanned in the interrupted scanning and the image of the same page after resuming scanning are displayed side by side. Then, a screen for accepting from the user whether or not to continue reading the image is displayed.

In addition, if the two images displayed side by side are different, for example, the order of the paper may be different between the first loaded paper bundle (multiple papers) and the paper bundle loaded when scanning is resumed. The orientation of the paper may have changed. It is also possible that some sheets were removed from the initially loaded stack of paper when scanning was resumed. Therefore, for example, when the user determines that the two images displayed side by side are different, he / she may choose not to continue reading in order to confirm the loaded paper bundle. On the other hand, when the two images displayed side by side are the same, it is highly possible that the same paper bundle as the first loaded paper bundle is set when scanning is restarted. Therefore, for example, when the user determines that the two images displayed side by side are the same, the user may choose to continue reading.

<Functional configuration of image processing device>
FIG. 2 is a block diagram showing a functional configuration example of the image processing device 100 according to the first embodiment. The image processing device 100 according to the present embodiment includes a paper transport control unit 101, an image reading control unit 102, a display control unit 103, and a paper determination unit 104.

The paper transport control unit 101 controls the operation of the paper transport unit 140. More specifically, the paper transport control unit 101 transports the paper stored in the paper storage unit of the paper transport unit 140 to the image reading unit 150, for example, when the user is instructed to read the image. Control to do. Further, the paper transport control unit 101 controls to transport the paper after being transported to the image reading unit 150 to the paper discharge loading unit.

The paper determination unit 104 acquires information on the number of sheets (count value) counted by the sensor 180. Here, the paper determination unit 104 acquires information from the sensor 180, and when the operation of reading by the image reading unit 150 is interrupted, the number of sheets of paper has been read, and the number of sheets of paper has been read. Understand whether an error occurred during the paper reading operation and the paper was interrupted. Then, when the reading of the plurality of sheets is resumed after the reading of the plurality of sheets is interrupted, the paper determination unit 104 determines that the paper conveyed from the paper accommodating unit to the image reading unit 150 is read in the interrupted manner. It is determined whether or not the paper corresponds to the last paper that has been read.

In addition, when scanning is resumed, among the sheets transported from the sheet accommodating section to the image reading section 150, the number of sheets corresponding to the number of sheets for which scanning has been completed in the interrupted scanning is counted in order from the first sheet. It is determined that the last paper at the time corresponds to the last paper that has been read in the interrupted scan.

For example, if a paper jam occurs when reading the fourth sheet of a plurality of sheets, the reading operation is interrupted, and then the reading is restarted, the paper accommodating unit moves to the image reading unit 150. It is determined that the first to third sheets of paper to be conveyed do not correspond to the last paper that has been read in the interrupted reading. These papers are papers that precede the paper that corresponds to the last paper that has been read in the interrupted scan. On the other hand, the fourth sheet of paper conveyed from the paper accommodating unit to the image reading unit 150 is determined to be the paper corresponding to the last paper that has been read in the interrupted scanning.

The image reading control unit 102 controls the operation of the image reading unit 150. More specifically, the image reading control unit 102 reads an image so as to read the image on the paper conveyed from the paper accommodating unit when, for example, the user operates to instruct to read the image. The unit 150 is controlled.

Here, when the reading of the plurality of sheets is resumed after the reading of the plurality of sheets is interrupted, the image reading control unit 102 tells the number of sheets of paper to be conveyed from the paper accommodating unit to the image reading unit 150. The operation of the image reading unit 150 is controlled according to whether or not the paper is used. In other words, the image reading control unit 102 controls the operation of the image reading unit 150 based on the determination by the paper determination unit 104.

More specifically, when the reading of a plurality of sheets is resumed after the reading of a plurality of sheets is interrupted, the paper conveyed from the paper accommodating unit to the image reading unit 150 is read in the interrupted reading. When the paper is before the paper corresponding to the last completed paper, the image reading control unit 102 controls the image reading unit 150 so as not to read the paper. In this case, the paper conveyed from the paper accommodating unit is not read, but is directly conveyed from the image reading unit 150 to the paper ejection loading unit. On the other hand, when the paper conveyed from the paper accommodating unit to the image reading unit 150 is the paper corresponding to the last paper that has been read in the interrupted reading, the image reading control unit 102 reads the paper. The image reading unit 150 is controlled to do so.

For example, if a paper jam occurs when reading the fourth sheet of a plurality of sheets of paper, the reading operation is interrupted, and then the reading is restarted, the paper accommodating unit shifts to the image reading unit 150. The first to third sheets of paper to be conveyed are not read and are fed blank. On the other hand, the image reading unit 150 reads the fourth sheet of paper conveyed from the paper accommodating unit to the image reading unit 150.

The display control unit 103 as an example of the display means generates a control signal for controlling the display on the operation panel 130, and controls the display on the operation panel 130. Here, the display control unit 103 displays, for example, an image based on the image data generated by the image reading unit 150 on the operation panel 130. In other words, the display control unit 103 controls the operation panel 130 so as to preview the paper read by the image reading unit 150.

More specifically, the display control unit 103 determines whether or not the reading by the image reading unit 150 is normally completed. When the reading is completed normally, the image based on the image data generated by the reading of the image reading unit 150 is displayed on the operation panel 130. As a result, the preview display of the paper read by the image reading unit 150 is performed.

On the other hand, when the reading operation is interrupted due to a paper jam or the like, the display control unit 103 stops the preview display at the image corresponding to the last paper for which the reading is completed. Then, the display control unit 103 displays a message notifying that the reading operation is interrupted due to an abnormality and a method of dealing with the abnormality on the operation panel 130. Further, the display control unit 103 displays on the operation panel 130 a restart method for restarting the reading operation.

Further, when the reading of a plurality of sheets is restarted after the reading is interrupted, the display control unit 103 reads the image of the paper that has been read in the interrupted reading (that is, the paper that has been read in the interrupted reading). Images based on the generated image data) are displayed in order. In other words, the display control unit 103 sequentially displays an image of the first paper that has been read in the interrupted reading to an image of the last paper that has been read in the interrupted reading.

Then, as described above, when the image reading unit 150 reads the paper corresponding to the last paper that has been read in the interrupted reading, the display control unit 103 displays a screen in which the two images are arranged side by side. Is displayed. These two images are a new image (an example of the first image data) generated for the last paper that has been read in the interrupted scan and a paper that corresponds to the last paper that has been read in the interrupted scan. It is an image generated by reading (an example of the second image data). In this screen, the user accepts a selection as to whether or not to continue reading. When the selection to continue reading is accepted, the reading by the image reading unit 150 is continued. That is, in the interrupted reading, the papers after the paper corresponding to the last paper whose reading is completed are sequentially read.

Then, each functional unit constituting the image processing device 100 shown in FIG. 2 is realized by the cooperation of software and hardware resources. Specifically, when the image processing device 100 is realized with the hardware configuration shown in FIG. 1, for example, an OS program or an application program stored in the ROM 110c is read into the RAM 110b and executed by the CPU 110a. As a result, each functional unit such as the paper transport control unit 101, the image reading control unit 102, the display control unit 103, and the paper determination unit 104 is realized.

<Processing procedure when reading operation is interrupted>
Next, a processing procedure when the image reading operation by the image processing device 100 is interrupted will be described. FIG. 3 is a flowchart showing an example of a processing procedure when the image reading operation is interrupted in the first embodiment.

For example, when the user stores the paper in the paper storage unit of the paper transport unit 140 and starts reading the image on the operation panel 130, the image reading unit 150 reads the paper (step 101). More specifically, the paper transport control unit 101 controls to transport the paper stored in the paper storage unit of the paper transport unit 140 to the image reading unit 150. Further, the image reading control unit 102 controls the image reading unit 150 so as to read an image on the conveyed paper. By such control, the image reading unit 150 reads the paper.

Further, the display control unit 103 determines whether or not the reading is normally completed (step 102). When the reading is completed normally (Yes in step 102), the display control unit 103 displays a preview of the paper read by the image reading unit 150 on the operation panel 130 (step 103). That is, the display control unit 103 displays an image based on the image data generated by the image reading unit 150 on the operation panel 130. On the other hand, if the reading is not normally completed due to a paper jam or the like (No in step 102), the process proceeds to step 105, which will be described later.

After step 103, the paper transport control unit 101 determines whether or not all the paper to be read has been transported (step 104). Here, for example, if the paper is still stored in the paper storage unit of the paper transport unit 140, the paper transport control unit 101 determines that there is paper that has not yet been transported (No in step 104). In this case, the process proceeds to step 101, the next sheet of paper is conveyed, and the image reading unit 150 reads the paper.

On the other hand, for example, if the paper is not stored in the paper storage unit of the paper transport unit 140, the paper transport control unit 101 determines that all the paper to be read has been transported (Yes in step 104). Then, this processing flow ends. In addition, by the processing of steps 101 to 104, images are sequentially read from the paper stored in the paper storage section of the paper transport section 140. Then, the preview of the read paper is sequentially displayed on the operation panel 130 from the first paper.

Next, a case where a negative determination (No) is made in step 102, that is, a case where an abnormality occurs in the reading operation and the reading operation is interrupted will be described. In this case, the display control unit 103 stops the preview display at the image of the last paper that has been read (step 105). In addition, the display control unit 103 sequentially displays the images corresponding to the paper read by the image reading unit 150 in accordance with the reading operation of the image reading unit 150. Then, when the reading operation is interrupted, the image corresponding to the last paper read by the image reading unit 150 is kept displayed.

Next, the display control unit 103 notifies on the operation panel 130 that an abnormality has occurred in the reading operation and interrupts the operation, and displays a method of dealing with the abnormality (step 106). For example, when a paper jam occurs, the display control unit 103 displays a message notifying that the paper jam has occurred and a screen showing how to deal with the paper jam on the operation panel 130.

When the user takes action against the abnormality, the display control unit 103 displays on the operation panel 130 a restart method for restarting the reading operation (step 107). Here, the display control unit 103 displays, for example, a message prompting the operation panel 130 to perform an operation of re-accommodating the paper bundle accommodated in the paper accommodating unit and resuming the reading of the image.

When the processing of the restart method is performed by the user, the reading by the image reading unit 150 is restarted. Here, the paper transport control unit 101 controls to transport the paper stored in the paper storage unit of the paper transport unit 140 to the image reading unit 150 (step 108). Further, the paper determination unit 104 is a paper that corresponds to the last paper that has been read in the interrupted reading, in which the paper conveyed from the paper storage unit to the image reading unit 150 is based on the information acquired from the sensor 180. Whether or not it is determined (step 109).

When a negative determination (No) is made in step 109, the image reading control unit 102 controls the image reading unit 150 so as not to read the image on the conveyed paper (step 110). That is, if a negative determination (No) is made in step 109, the paper is blank-fed. In this case, the paper conveyed from the paper accommodating unit is not read, but is directly conveyed from the image reading unit 150 to the paper ejection loading unit. Then, the process proceeds to step 108, and the next paper is conveyed from the paper accommodating unit to the image reading unit 150.

On the other hand, when a positive determination (Yes) is made in step 109, the image reading control unit 102 controls the image reading unit 150 so as to read the image on the conveyed paper (step 111). By this control, the image reading unit 150 reads the paper corresponding to the last paper that has been read in the interrupted reading.

Next, the display control unit 103 displays the two images side by side (step 112). These two images are an image that has been generated for the last paper that has been read in the interrupted reading, and an image that is newly generated by reading the paper under the control of step 111. Here, the display control unit 103 arranges the two images side by side and displays a screen that accepts the selection of whether or not to continue reading. Then, the display control unit 103 determines whether or not the selection to continue reading is accepted on the screen (step 113).

If a positive decision (Yes) is made in step 113, reading continues. In this case, the process proceeds to step 101, the paper transport control unit 101 controls the paper transport unit 140 so as to transport the paper stored in the paper storage unit to the image reading unit 150, and the image reading control unit 102 controls the image reading control unit 102. The image reading unit 150 is controlled so as to read an image on the conveyed paper.

On the other hand, when a negative determination (No) is made in step 113, the display control unit 103 displays a response method for continuing reading (step 114). For example, in the display control unit 103, the paper bundle set at the time of restart (that is, the paper bundle stored in the paper storage unit by the restart method of step 107) is the same as the paper bundle set at the interrupted reading. Display a message prompting you to confirm. Further, for example, the display control unit 103 displays a message prompting the operation panel 130 to perform an operation of re-accumulating the paper bundle after confirming the paper bundle and re-accumulating the paper bundle in the paper accommodating unit. When the user performs an operation to restart reading, the reading by the image reading unit 150 is restarted, and the process proceeds to step 108.

In the above-mentioned example, it was decided to move to step 108 after step 114, but the configuration is not limited to this. For example, when the user performs an operation of resuming reading, the process proceeds to step 101, and the image reading unit 150 may newly read sequentially from the first sheet of paper to generate image data.

<Specific example of processing when reading operation is interrupted>
Next, a process when the image reading operation by the image processing device 100 is interrupted will be described with reference to specific examples. 4 to 4-3 are diagrams for explaining a specific example of processing when the image reading operation by the image processing apparatus 100 is interrupted in the first embodiment.

First, when the user stores the paper in the paper storage unit of the paper transport unit 140 and performs an operation to start reading the image on the operation panel 130, the paper is sequentially conveyed from the paper storage unit, and the paper is conveyed by the image reading unit 150. Reading starts. Then, on the operation panel 130, an image based on the image data generated for the paper read by the image reading unit 150 is displayed.

FIGS. 4-1 (a) and 4-1 (b) are diagrams showing an example of a screen displayed during the reading operation. When the image reading unit 150 reads the paper, images based on the image data generated by the reading (images corresponding to the read paper) are sequentially displayed. FIG. 4-1 (a) shows an example when the first sheet and the second sheet are read. The image 11 is an image corresponding to the first sheet of paper read by the image reading unit 150. Further, the image 12 is an image corresponding to the second sheet of paper read by the image reading unit 150.

Further, when the third sheet of paper is read by the image reading unit 150, the image 13 corresponding to the third sheet of paper is further displayed as shown in FIG. 4-1 (b). In this way, in accordance with the reading operation by the image reading unit 150, the images corresponding to the read paper are sequentially displayed so as to flow from right to left in the figure. The sensor 180 detects each sheet of paper transported from the paper storage unit of the paper transport unit 140 to the image reading unit 150, and counts the number of detected sheets.

Here, if an abnormality occurs in the reading operation due to a paper jam or the like and the reading operation is interrupted, the preview display of the paper is stopped. FIG. 4-1 (c) is a diagram showing an example of a screen displayed when the reading operation is interrupted. FIG. 4-1 (c) shows an example in which a paper jam occurs when the image reading unit 150 reads the fourth sheet of paper. Here, the last sheet that has been read by the image reading unit 150 is the third sheet. Therefore, the preview display is stopped while the image corresponding to the third sheet of paper is displayed. In addition, an image 14 of a message notifying that a paper jam has occurred is displayed.

By acquiring the information on the number of sheets counted by the sensor 180, the paper determination unit 104 completes reading up to the third sheet, and an abnormality occurs during the operation of reading the fourth sheet. To understand that the reading was interrupted.

Next, the operation panel 130 displays a method of dealing with the abnormality. FIG. 4-2 (d) is a diagram showing an example of a screen showing a method of dealing with a paper jam. In the image 15 shown in FIG. 4-2 (d), the location where the paper jam occurs is the “area 1” in the image processing device 100, and as a corresponding procedure for clearing the paper jam, “Open the right cover”. Please remove the jammed paper. "

When the user responds to a paper jam, a resumption method for resuming the reading operation is displayed. FIG. 4-2 (e) is a diagram showing an example of a screen showing a restart method for restarting the reading operation. Image 16 shown in FIG. 4-2 (e) shows a message "Please re-accumulate from the first sheet and press the resume button" as a restart method for restarting the reading operation. This message prompts the user to perform an operation of re-accommodating the bundle of papers accommodated in the interrupted reading from the first sheet including the completed papers and restarting the reading.

When the processing of the restart method is performed by the user, the reading by the image reading unit 150 is restarted. In this example, it is the fourth sheet that the abnormality occurred during the reading operation, and the last sheet that has been read by the image reading unit 150 is the third sheet. Therefore, after resuming reading, the first sheet of paper and the second sheet of paper are not read and are fed blank.

Further, here, the paper determination unit 104 sets the paper conveyed from the paper storage unit to the image reading unit 150 as the last paper whose reading is completed in the interrupted reading, based on the information acquired from the sensor 180. Determine if it is the corresponding paper. Then, the paper determination unit 104 sets the first sheet of paper and the second sheet of the paper conveyed from the paper storage unit to the image reading unit 150 as the last paper whose reading is completed in the interrupted reading. Judge that it does not correspond. Then, the image reading control unit 102 controls the image reading unit 150 so that the image is not read on the first sheet of paper and the second sheet of paper.

Further, when the third sheet of paper is conveyed from the paper accommodating unit to the image reading unit 150, the paper determining unit 104 determines that the paper corresponds to the last paper that has been read in the interrupted reading. .. Then, the image reading control unit 102 controls the image reading unit 150 so as to read an image on the third sheet of paper.

4-3 (f) and 4-3 (g) are diagrams showing an example of a screen displayed after the reading operation is restarted. After the reading operation is restarted, the images corresponding to the paper already read by the image reading unit 150 are sequentially displayed. In other words, images based on the image data generated in the interrupted reading are displayed in sequence. In the example shown in FIG. 4-3 (f), the image 11 corresponding to the first sheet, the image 12 corresponding to the second sheet, and the image 13 corresponding to the third sheet are displayed. The images 11 to 13 are the same as the images 11 to 13 shown in FIG. 4-1 (b). In this way, each image is sequentially displayed so as to flow from right to left in the figure according to the paper conveyed from the paper accommodating portion. These images are displayed so as to flow from right to left in the figure so as to fast-forward at high speed so as to represent, for example, the state of blank-feeding the paper.

In addition, on the operation panel 130, each image is sequentially displayed according to the paper conveyed from the paper accommodating portion. Then, when the paper corresponding to the last paper that has been read in the interrupted reading (in this example, the third paper) is reached, the preview display is stopped. Here, for example, the image corresponding to the third sheet of paper is displayed so as to flow from right to left in the figure, and the preview display is stopped when the image reaches the center of the screen of the operation panel 130.

Next, on the operation panel 130, an image generated for the last paper that has been read in the interrupted scanning and an image corresponding to the newly scanned paper after resuming scanning are displayed side by side. In the example shown in FIG. 4-3 (g), the image 13 is displayed as a generated image of the last paper that has been read in the interrupted reading. This image 13 is the same as the image 13 shown in FIG. 4-1 (b). Further, the image 17 is displayed as an image corresponding to the newly read paper. This image 17 is an image generated by reading a third sheet of paper that is conveyed after resuming reading.

Here, when the user selects to continue reading (that is, when the "OK" button 18 is selected), reading is continued. In this case, the images are continuously read from the fourth sheet. On the other hand, when the user selects not to continue reading (that is, when the "NG" button 19 is selected), a response method for continuing reading is displayed. Then, for example, when the user performs an operation of re-accommodating the paper bundle in the paper accommodating unit and restarting the reading, the reading by the image reading unit 150 is restarted. In this case, as described above, for example, when the first sheet and the second sheet are blank-fed and the third sheet is read, as shown in FIG. 4-3 (g). Two images are displayed.

As described above, in the present embodiment, when the image processing apparatus 100 interrupts the reading of a plurality of sheets and then resumes the reading of the plurality of sheets, the last reading is completed in the interrupted reading. The generated image and the image generated by newly scanning the paper corresponding to the last paper are displayed. Then, the selection of whether or not to continue reading is accepted. Therefore, the user may check the screen and select whether or not to continue reading.

[Embodiment 2]
Next, Embodiment 2 of the present invention will be described. In the first embodiment, the image processing device 100 displays two images, and the user selects whether or not to continue reading. On the other hand, in the second embodiment, the image processing apparatus 100 compares the two images before displaying the two images, and determines whether or not the degree of difference between the two images exceeds a predetermined degree. .. Then, when it is determined that the degree of difference between the two is less than or equal to a predetermined degree, the reading is continued as it is. On the other hand, when it is determined that the degree of difference between the two exceeds a predetermined degree, the image processing apparatus 100 arranges the two images side by side and continues reading, as in the first embodiment. Display a screen that accepts the selection. In the present embodiment, the same reference numerals as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

<Functional configuration of image processing device>
FIG. 5 is a block diagram showing a functional configuration example of the image processing device 100 according to the second embodiment. The image processing device 100 according to the present embodiment is different from the first embodiment in that the image comparison unit 105 is newly provided.

When the scanning is resumed after the scanning operation by the image reading unit 150 is interrupted, the image comparing unit 105 reads the image generated for the last paper that has been scanned in the interrupted scanning and the scanning in the interrupted scanning. The paper corresponding to the last completed paper is newly scanned and compared with the generated image. Then, the image comparison unit 105 determines whether or not the degree of difference between the two images exceeds a predetermined degree.

If it is determined that the degree of difference between the two images is less than or equal to a predetermined degree, the reading of the images is continued. That is, in the interrupted reading, the papers after the paper corresponding to the last paper whose reading is completed are sequentially read. On the other hand, when it is determined that the degree of difference between the two images exceeds a predetermined degree, the display control unit 103 displays a screen in which the two images are arranged side by side. It should be noted that this screen indicates that the degree of difference between the two images is equal to or greater than a predetermined degree, and accepts the user to select whether or not to continue reading.

When it is determined that the degree of difference between the two images is less than or equal to a predetermined degree, the display control unit 103 newly reads the paper corresponding to the last paper that has been read in the interrupted reading, and is generated. The image is not displayed. However, in order to inform the user that the degree of difference between the two images does not exceed a predetermined degree, the display control unit 103 newly reads the paper and displays the generated image, or displays the two images. May be displayed side by side.

Further, the image comparison unit 105 compares the images by a conventional method. For example, the image comparison unit 105 compares the pixel values of pixels existing at the same position (coordinates) in two images. Then, when the ratio of the pixels having the same pixel values (or the pixels having the difference in the pixel values within a certain range) among all the pixels in the image is equal to or more than a predetermined ratio, the image comparison unit 105 determines. It is determined that the degree of difference between the two images is less than or equal to a predetermined degree.

<Processing procedure when reading operation is interrupted>
Next, a processing procedure when the image reading operation by the image processing device 100 is interrupted will be described. FIG. 6 is a flowchart showing an example of a processing procedure when the image reading operation is interrupted in the second embodiment.

For example, when the user stores the paper in the paper storage unit of the paper transport unit 140 and starts reading the image on the operation panel 130, the image reading unit 150 reads the paper. Here, since the processes of steps 201 to 211 are the same as the processes of steps 101 to 111, the description thereof will be omitted here.

After step 211, that is, after the image reader 150 reads the paper corresponding to the last paper that has been read in the interrupted scan, the image comparison unit 105 compares the two images ( Step 212). Here, the image comparison unit 105 compares the image generated for the last paper that has been read in the interrupted reading with the image newly generated by reading the paper under the control of step 211. Next, the image comparison unit 105 determines whether or not the degree of difference between the two images exceeds a predetermined degree (step 213).

If a negative determination (No) is made in step 213, that is, if the degree of difference is determined to be less than or equal to a predetermined degree, reading is continued. In this case, the process proceeds to step 201, the paper transport control unit 101 controls the paper transport unit 140 so as to transport the paper stored in the paper storage unit to the image reading unit 150, and the image reading control unit 102 controls the image reading control unit 102. The image reading unit 150 is controlled so as to read an image on the conveyed paper.

On the other hand, when a positive judgment (Yes) is made in step 213, that is, when it is determined that the degree of difference exceeds a predetermined degree, the display control unit 103 displays the two images side by side (step). 214). Since the processes of steps 214 to 216 are the same as the processes of steps 112 to 114, respectively, the description thereof will be omitted here.

<Screen display example>
Next, a screen displayed when it is determined by comparison of the image comparison unit 105 that the degree of difference between the two images exceeds a predetermined degree will be described with reference to specific examples. FIG. 7 is a diagram showing an example of a screen displayed when it is determined that the degree of difference between the two images exceeds a predetermined degree. Here, it is assumed that a paper jam occurs when the fourth sheet of paper is read, the reading operation is interrupted, and then the image reading is restarted.

Image 21 shown in FIG. 7 is an image generated for the last sheet of paper that has been read in the interrupted reading. That is, the image 21 is an image generated by reading the third sheet of paper in the interrupted reading. Further, the image 22 is an image corresponding to the paper newly read after resuming reading. That is, the image 22 is an image generated by reading the third sheet of paper that is conveyed after resuming reading. Then, it is determined by the comparison of the image comparison unit 105 that the degree of difference between the two exceeds a predetermined degree, and the message "The scanned images after resumption do not match. Please check." Is displayed. There is.

Here, when the user selects to continue reading (that is, when the "OK" button 23 is selected), reading is continued. In this case, the images are continuously read from the fourth sheet. On the other hand, when the user selects not to continue reading (that is, when the "NG" button 24 is selected), a response method for continuing reading is displayed.

As described above, in the present embodiment, when the image processing apparatus 100 interrupts the reading of a plurality of sheets and then resumes the reading of the plurality of sheets, the last reading is completed in the interrupted reading. The generated image of the paper is compared with the image generated by newly scanning the paper corresponding to the last paper. Then, as a result of comparison, when the degree of difference between the two images is less than or equal to a predetermined degree, the reading of the image is automatically continued without accepting the user's operation. Therefore, for example, even if the degree of difference does not exceed a predetermined degree, the degree of difference is determined in advance as compared with a configuration in which a user selects whether to continue reading or not. The user's effort to continue reading when it does not exceed is reduced. If the degree of difference exceeds a predetermined degree, the two images are displayed and the user selects whether or not to continue reading.

Further, in the second embodiment, when the image comparison unit 105 determines that the degree of difference between the two images exceeds a predetermined degree, the scanning is resumed in the paper that has been read in the interrupted reading. Later, it may be possible to search for a paper corresponding to the newly read paper. In other words, in the image comparison unit 105, among the images of the paper that has been read in the interrupted reading, the degree of difference from the image of the newly read paper after resuming the reading is equal to or less than a predetermined degree. You may search for it.

Here, the image comparison unit 105 may perform a search by rotating the image or changing the orientation of the image. Then, when an image is found in which the degree of difference from the image of the newly read paper after resuming reading is equal to or less than a predetermined degree, for example, the display control unit 103 causes the newly read paper after resuming reading. The image of the above and the newly found image may be displayed side by side, and a message prompting the user to confirm that the order and orientation of the loaded papers have not changed at the time of restarting may be displayed.

Further, in the first and second embodiments, when the reading is resumed after the scanning is interrupted, the image is read for the paper before the paper corresponding to the last paper in which the scanning is completed in the interrupted scanning. Although it was decided not to do this, the image may be read. That is, the image reading unit 150 may also read the image on the paper before the paper corresponding to the last paper whose reading is completed in the interrupted reading. In this case, for example, the preview display displays an image generated by scanning the paper to be conveyed after resuming scanning.

Here, the image comparison unit 105 may compare the image of the paper that has been read in the interrupted reading with the image of the newly read paper after resuming the reading for each paper. Then, as a result of the comparison, for example, when the order is changed between the image of the paper that has been read in the interrupted reading and the image of the paper that has been newly read after resuming scanning, the image comparison unit 105 newly reads after resuming scanning. The order of the images on the scanned paper may be rearranged according to the order of the images on the paper that have been scanned in the interrupted scanning.
Further, the image comparison unit 105 may rotate the image or change the orientation of the image to compare the images.

Further, the program that realizes the embodiment of the present invention can be provided not only by communication means but also by storing it in a recording medium such as a CD-ROM.

Although various embodiments and modifications have been described above, it is of course possible to combine these embodiments and modifications.
Further, the present disclosure is not limited to the above-described embodiment, and can be implemented in various forms without departing from the gist of the present disclosure.
