  According to the image forming apparatus 11 configured as described above, an image is read by the image reading unit 10, and an image is formed on the paper fed from the paper supply unit 82 in the image forming unit 80 based on the read data. Is done.

  FIG. 3 shows a block diagram of the image forming apparatus 11 according to the present embodiment. As shown in FIG. 3, the image forming apparatus 11 includes a computer 50.

  The computer 50 includes a CPU (Central Processing Unit) 50A, a ROM (Read Only Memory) 50B, a RAM (Random Access Memory) 50C, a non-volatile memory 50D, and an input / output interface (I / O) 50E via a bus 50F. It is a connected configuration. The CPU 50 is an example of a display unit and a processing unit.

  The I / O 50E includes an operation unit 60, a display unit 62, an image reading unit 10, an image forming unit 80, a paper supply unit 82, a paper discharge unit 84, a network communication interface (I / F) 86, a telephone line interface (I / O). F) Each functional unit such as 88 and the hard disk 90 is connected.

  The operation unit 60 includes various buttons such as a start button and a numeric keypad for instructing to start copying.

  The display unit 62 displays various screens such as a setting screen for setting various image forming conditions such as copy density and a confirmation screen for confirming a preview image (reference image) described later. In the present embodiment, the display unit 62 is configured by a touch panel capable of performing various operations by touching with a finger on various screens. The display unit 62 is an example of a detection unit according to the present invention.

  The telephone line communication I / F 88 is an interface for performing facsimile communication with other image forming apparatuses connected via a telephone line (not shown).

  The hard disk 90 stores, for example, log data such as the status and operating status of each part of the apparatus, log data of processing results such as copying, facsimile communication, and printing, various setting data, a display control program described later, and the like.

  By the way, in the image forming apparatus 11 according to the present embodiment, when a plurality of documents are set on the document table 20 and reading is instructed, a preview image is generated from the images of the documents sequentially read by the image reading unit 10. The display unit 62 has a function of displaying a list screen of the generated preview images.

  FIG. 4 shows an example of a preview image list screen. On the list screen shown in FIG. 4, preview images PV <b> 1 to PV <b> 10 for the first to tenth pages of the document read by the image reading unit 10 are displayed. Then, in the image forming apparatus 11, for example, when the user gives an instruction to process the preview image to be processed by a predetermined gesture operation, the process according to the gesture operation is executed. Here, the process instructed by the user is, for example, a process of changing the attribute of the processing target image corresponding to the preview image in which the process is instructed. The attributes include, but are not limited to, at least one of, for example, image orientation, image order, image size, and the like. In the present embodiment, a case will be described in which processing for rotating the orientation of an image is executed as processing for changing an attribute. For example, when a gesture operation is performed to draw a circle on the processing target preview image, the processing target image corresponding to the preview image is rotated by 90 degrees, for example. At this time, since the preview image is small, it is difficult to recognize which preview image the user has performed the gesture operation. For this reason, the image forming apparatus 11 executes display control processing for enlarging at least a part of the preview image on which the gesture operation is performed so that the user can easily recognize which preview image has been selected. Note that the correspondence between the gesture operation and the process corresponding to the gesture operation is not limited to the above example, and is arbitrarily set. As described above, in this embodiment, when a certain operation is instructed by performing a gesture operation on the preview image displayed on the list screen, the preview image is enlarged and displayed. In other words, when the user performs a gesture operation with the intention of enlarging the preview image, when the gesture operation is instructed to perform some processing that is the original purpose, the preview is attached to the gesture operation. An image is enlarged and displayed.

  Next, a preview image display control process executed by the CPU 50 will be described with reference to the flowchart shown in FIG. The display control process shown in FIG. 5 is executed when the preview image list screen is displayed on the display unit 62.

  In step S100, it is determined whether or not any operation has been detected. If an operation is detected, the process proceeds to step S102. If no operation is detected, the process waits until an operation is detected. To do.

  In step S102, it is determined whether or not the detected operation is an operation for instructing some processing on the processing target image (read image) corresponding to the preview image. For example, in the case of an operation for instructing processing to rotate the processing target image for which processing is instructed 90 degrees clockwise, a circle is clocked on the preview image PV corresponding to the processing target image as shown in FIG. A gesture operation JS1 such as drawing around is performed with a finger. In FIG. 6, for convenience of explanation, only one preview image PV is displayed, and the display of other preview images is omitted.

  In step S104, as shown in FIG. 7, an enlarged image PV-A obtained by enlarging a part of the preview image PV corresponding to the processing target image is displayed. The area to be enlarged is, for example, an area surrounded when a gesture operation JS1 as shown in FIG. 6 is performed. Note that an area other than the area surrounded when the gesture operation JS1 is performed may be enlarged, or the entire preview image PV may be enlarged.

  Here, the user refers to the enlarged image PV-A, confirms whether or not the preview image instructed for processing is as intended, and performs an operation indicating that the confirmation is OK as intended. On the other hand, whether or not the preview image for which the process is designated is as intended is confirmed, and if it is not as intended, an operation indicating that the confirmation image is NG is performed. The operation indicating that the confirmation is OK may be, for example, an operation of tapping the preview image PV or the enlarged image PV-A once. Although not shown, an OK button displayed on the display unit 62 is displayed. It is good also as operation to tap. Further, the operation indicating that it is confirmation NG may be, for example, an operation of tapping a region other than the preview image PV and the enlarged image PV-A once, and is displayed on the display unit 62 although illustration is omitted. It is good also as operation which taps a NG button.

  In step S106, it is determined whether or not the confirmation is OK. If the confirmation is OK, the process proceeds to step S108. If the confirmation is NG, the process proceeds to step S110.

  In step S108, the instructed process is executed for the processing target image. As a result, the processing target image corresponding to the preview image PV is rotated by 90 degrees. At this time, for example, as shown in FIG. 8, an enlarged image PV-B obtained by enlarging the preview image PV may be displayed on the display unit 62 in order to make it easy to recognize the processing content.

  In step S110, it is determined whether an operation other than the operation for instructing the processing target image and the operation for ending the display of the preview image list screen have been performed. If the determination is affirmative, the process proceeds to step S112. If the determination is negative, the process proceeds to step S114.

  In step S112, processing corresponding to the operation is executed.

  In step S114, it is determined whether or not an operation for ending the display of the preview image list screen has been performed. If the determination is affirmative, this routine is terminated. If the determination is negative, the process proceeds to step S100.

  As described above, in this embodiment, when a process such as a rotation process is instructed with respect to the preview image, a part of the instructed preview image is enlarged and displayed, so that the image instructed to be processed is recognized. It becomes easy to do. Further, since the enlargement display is executed only by the one-step operation of selecting the preview image, not the two-step operation of selecting the preview image and the operation of enlarging the selected preview image, the operation is simplified. The

(Second Embodiment)

  Next, a second embodiment of the present embodiment will be described. In addition, the same code | symbol is attached | subjected to the same part as 1st Embodiment, and the detailed description is abbreviate | omitted.

  In the second embodiment, when a preview image is instructed to be processed and a degree of operation is greater than a predetermined reference level, a plurality of preview images including the preview image instructed to be processed are displayed in an enlarged manner Will be described.

  The apparatus configuration of the image forming apparatus according to the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  Next, a preview image display control process executed by the CPU 50 will be described with reference to the flowchart shown in FIG.

  The display control process shown in FIG. 9 differs from the display control process shown in FIG. 5 in that steps S103 and S105 are added. Other processing is the same as the display control processing shown in FIG.

  In step S103, it is determined whether or not the degree of operation for instructing the preview image to be processed is larger than a predetermined reference degree. For example, as shown in FIG. 6, when the gesture operation JS1 is performed with a finger on the preview image PV, the degree of operation is greater than the reference degree when the rotation speed of the gesture operation JS1 is faster than a predetermined reference rotation speed. Judged to be large.

  In addition, when the structure which detects the pressure at the time of pushing down a screen is employ | adopted for the display part 62, when the pressure at the time of pushing down the screen of the display part 62 is more than a predetermined pressure, the degree of operation is a reference | standard You may make it determine with it being larger than a degree.

  And when it is affirmation determination by step S103, it transfers to step S104, and when it is negative determination, it transfers to step S105.

  In step S105, a plurality of preview images including the preview image instructed to be processed are displayed on the display unit 62 in accordance with the degree of operation. For example, as shown in FIG. 10, when a gesture operation JS2 is performed with a finger to draw a circle in the vicinity of the preview image PV1, the rotation speed of the gesture operation is higher than a predetermined reference rotation speed. As shown in FIG. 11, the enlarged images PV1-A, PV2-A, and PV3-A are displayed by enlarging a part of the three preview images of the preview images PV1, PV2, and PV3. The example of FIG. 11 is a case where the number of preview images to be enlarged is three, but the number of preview images to be enlarged is set according to the rotation speed. That is, the number of preview images to be enlarged and displayed increases as the rotation speed increases, and the number of preview images to enlarge and display decreases as the rotation speed decreases.

  As described above, in the present embodiment, when instructing processing to a preview image, if the degree of operation is greater than a predetermined reference degree, a plurality of preview images including the preview image instructing processing are enlarged. Since it is displayed, processing instructions for a plurality of preview images are collected, and a plurality of preview images to be processed can be easily recognized.

(Third embodiment)

  Next, a third embodiment of the present embodiment will be described. In addition, the same code | symbol is attached | subjected to the same part as said each embodiment, and the detailed description is abbreviate | omitted.

  In the third embodiment, a case will be described in which the same processing is performed not only on a processing target image corresponding to a preview image for which processing is instructed but also on an approximate image that approximates the processing target image.

  The apparatus configuration of the image forming apparatus according to the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  Next, as an operation of the present embodiment, a preview image display control process executed by the CPU 50 will be described with reference to a flowchart shown in FIG.

  The display control process shown in FIG. 12 differs from the display control process shown in FIG. 5 in that steps S103A, S105A, S109A, and S109B are added. Other processing is the same as the display control processing shown in FIG.

  In step S103A, it is determined whether or not there is an approximate image that approximates the processing target image corresponding to the preview image for which processing is instructed among the images (read images) corresponding to the preview image displayed on the display unit 62. To do. Here, as a method for determining whether or not an image is approximate, for example, the following determination method can be given.

  As a first determination method, for example, an OCR (Optical Character Recognition) process is performed on each image corresponding to each preview image, and the position and character string of additional information including at least one of a header and a footer of the processing target image It may be determined whether there is an image that approximates the processing target image by determining whether there is an image having additional information similar to each other. Note that various known methods are used to determine whether or not the character strings are similar.

  Further, as a second determination method, there is an image having heading information in which the position of heading information (chapter, section) of the processing target image is similar to each other corresponding to each preview image. By determining whether or not there is an image that approximates the processing target image, it may be determined.

  Further, as a third determination method, whether or not there is an image in the same character string direction as the character string direction included in the processing target image by performing OCR processing on each of the images corresponding to each preview image. It may be determined whether there is an image that approximates the processing target image.

  In addition, you may determine combining the 1st-3rd determination method. That is, when an affirmative determination is made by at least one of the first to third determination methods, it may be determined that there is an image that approximates the processing target image.

  In step S103A, if it is determined that there is no approximate preview image, the process proceeds to step S104. If it is determined that an approximate preview image exists, the process proceeds to step S105A.

  In step S105A, not only the preview image corresponding to the processing target image but also the preview image corresponding to the approximate image is enlarged together.

  For example, as shown in FIG. 13, when a gesture operation JS3 is performed to draw a circle clockwise on the preview image PV1, the preview image has a character string similar to the same position as the processing target image corresponding to the preview image PV1. An image corresponding to PV3 is determined as an approximate image. In this case, as shown in FIG. 14, not only the enlarged image PV1-A in which the preview image PV1 is enlarged, but also the enlarged image PV3-A in which the preview image PV3 corresponding to the approximate image is enlarged is displayed together.

  If it is determined that the confirmation is OK in step S106, not only the preview image PV1 corresponding to the processing target image but also the preview image PV3 corresponding to the approximate image is rotated together in step S108 as shown in FIG. The

  In step S <b> 109 </ b> A, it is determined whether or not there is an approximate image that approximates the processing target image in the non-display image in which the preview image is not displayed on the display unit 62 among the plurality of read images. If step S109A is affirmative, the process proceeds to step S109B. If negative, the process proceeds to step S110.

  In step S109B, a confirmation process for confirming whether or not to execute the process on the approximate image is executed, and the process is executed on the approximate image instructed to execute the process. Specifically, for example, a confirmation screen as shown in FIG. As an example, this confirmation screen is a screen for confirming whether or not to execute a process of rotating an approximate image that is not displayed on the preview image list screen among a plurality of read images.

  In the confirmation screen shown in FIG. 16, for each approximate image not displayed on the preview image list screen, a page area AR displaying a page number Pn and a check box CK, a scroll button SK, and confirmation buttons K1 and K2 are displayed. ing. In the example of FIG. 16, the fifth page, the tenth page, the twelfth page, and the eighteenth page are approximate images corresponding to the processing target image. Here, the page for which the check box CK is “□” is an image for which rotation is not set by the user, and the page for which the check box CK is “■” is an image for which rotation is set by the user. Indicates.

  For example, when the page area AR of the fifth page is clicked, a confirmation screen as shown in FIG. 17 is displayed. In the confirmation screen shown in FIG. 17, the preview image of the page 5 which is originally long horizontally is rotated 90 degrees and displayed as a vertically long preview image PV5. Here, when the user presses the confirmation button K3 displayed as “Yes”, the image of the fifth page is set to rotate, and when the user presses the confirmation button K4 displayed as “Return (does not rotate)”, It is set not to rotate the image of the fifth page. When the confirmation button K3 or K4 is pressed on the confirmation screen of FIG. 17, the screen returns to the confirmation screen of FIG.

  Then, on the confirmation screen of FIG. 16, when the confirmation button K1 displayed as “Yes (rotate all at once)” is pressed, the approximate images of the pages whose check boxes CK are “■” are rotated all at once. And displayed on the display unit 62. On the other hand, when the confirmation button K2 displayed as “No” is pressed, the image is not rotated and the display of the confirmation screen is terminated.

  In addition, it is good also as a confirmation screen as shown in FIG. In the confirmation screen shown in FIG. 18, in the display area A1 at the bottom of the screen, among the images corresponding to the preview images not displayed on the preview image list screen, a list of preview images of approximate images that approximate the processing target image is displayed. They are displayed side by side in the arrow X direction. In the display area A2 at the top of the screen, an enlarged image obtained by enlarging the preview image selected from the display area A1 is displayed side by side in the X direction. The display area A1 is displayed by sliding in, for example, the arrow Y direction from the lower side of the screen so that the display of the display area A2 is not disturbed. FIG. 18 shows an example in which the number of preview images displayed in the display area A2 is two. However, the number of preview images displayed is not limited to two.

  When the user selects a preview image to be rotated in the same manner as the processing target image from among the preview images displayed in the display area A1, a preview image obtained by enlarging the selected preview image is displayed in the display area A2. The Further, when a preview image that is not to be rotated is selected by a gesture operation from among the preview images that are enlarged and displayed in the display area A2, the preview image is deleted from the display area A2.

  Further, when a preview image to be rotated is clicked among the preview images displayed in the display area A1 and the selection button B1 is pressed, a preview image obtained by enlarging the selected preview image is displayed in the display area A2. May be displayed. In addition, when a button B2 for clicking the preview image that is not desired to be rotated among the preview images enlarged and displayed in the display area A2 is pressed, the preview image may be deleted from the display area A2.

  In FIG. 18, as an example, a preview image PV3-A obtained by enlarging the preview image PV3 of the third page selected from the display area A1 is displayed in the display area A2. In the example of FIG. 18, the preview images PV7 and PV9 on the seventh and ninth pages are also selected from the preview images not displayed in the display area A1, but the number of preview images displayed in the display area A2 is the same. Since there are two, only the preview image PV7-A obtained by enlarging the preview image PV7 is displayed in the display area A2. Further, a message M1 indicating that the preview images PV7 and PV9 of the seventh and ninth pages are also recognized so as to be easily recognized.

  Further, in the display area A1, for example, when an operation of sliding in the arrow X direction is performed, the display of the preview image in the display area A1 is scrolled in the arrow X direction.

  Accordingly, for example, preview images PV7 and PV9 of the seventh and ninth pages that are not displayed in the display area A1 in FIG. 18 are displayed in the display area A1 and enlarged as shown in FIG. -A and PV9-A are displayed in the display area A2.

  When the preview image is enlarged and displayed in the display area A2, the enlargement ratio is set based on the size of the display area A2 and the number of preview images displayed in the display area A2.

  For example, as shown in FIG. 20, when the number of preview images to be displayed in the display area A2 is set to three, a circle is drawn clockwise on the preview image PV1 displayed in the display area A1. When the gesture operation JS4 is performed, a preview image PV1-A obtained by enlarging the preview image PV1 at an enlargement ratio that fits in the divided area A21 among the divided areas A21 to A23 obtained by dividing the display area A2 into three in the X direction is displayed in the divided area 21. To do.

  Further, as shown in FIG. 21, when a gesture operation JS5 for drawing a circle clockwise on the preview image PV1 displayed in the display area A1 is performed, the rotation speed of the gesture operation JS5 is a predetermined reference rotation. When the preview images PV1 and PV2 for two pages are selected faster than the speed, the preview images PV1-A and PV2-A obtained by enlarging the selected preview images PV1 and PV2 are displayed in the divided areas A21 and A22, respectively. To do.

  As described above, in the present embodiment, the same processing is performed not only on the preview image corresponding to the processing target image but also on the preview image corresponding to the approximate image approximating the processing target image. There is no need to specify each one, and the user's effort is reduced.

(Fourth embodiment)

  Next, a fourth embodiment of the present embodiment will be described. In addition, the same code | symbol is attached | subjected to the same part as said each embodiment, and the detailed description is abbreviate | omitted.

  In the fourth embodiment, a non-approximate image determined not to approximate the processing target image is warned as an image inappropriate for the instructed process, and whether or not to individually instruct processing for each non-approximate image. The case of setting will be described.

  The apparatus configuration of the image forming apparatus according to the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  Next, as a function of the present embodiment, a preview image display control process executed by the CPU 50 will be described with reference to a flowchart shown in FIG.

  The display control process shown in FIG. 22 differs from the display control process shown in FIG. 12 in that step S109C is executed instead of step S109A, and step S109D is executed instead of step S109B. Other processing is the same as the display control processing shown in FIG.

  In step S109C, it is determined whether or not there is a non-approximate image that does not approximate the processing target image among the plurality of read images that are not displayed on the preview image list screen. If step S109C is affirmative, the process proceeds to step S109D. If negative, the process proceeds to step S110.

  In step S109D, a warning is given that there is a non-approximate image that is not a rotation target, and a confirmation process for confirming whether or not to execute the process on the non-approximate image is executed and the process is executed. The process is executed on the non-approximate image instructed. Specifically, for example, a confirmation screen as shown in FIG. As an example, this confirmation screen is a screen for confirming whether or not to execute a process of rotating a non-approximate image that is not displayed on the display unit 62 among a plurality of read images.

  In the confirmation screen shown in FIG. 23, a page area AR displaying a page number Pn and a check box CK for each non-approximate image, a scroll button SK, and confirmation buttons K1 and K2 are displayed. In the example of FIG. 23, the 8th, 11th, 12th, and 19th pages are non-approximate images. Here, the page for which the check box CK is “□” is an image for which rotation is not set by the user, and the page for which the check box CK is “■” is an image for which rotation is set by the user. Indicates.

  Then, for example, when the page area AR of the 11th page is clicked, a confirmation screen as shown in FIG. 24 is displayed. In the confirmation screen shown in FIG. 24, the vertically long preview image of the eleventh page is rotated 90 degrees and displayed as a horizontally long preview image PV11. When the user presses the confirmation button K3 displayed as “Yes”, the image on the 11th page is set to rotate, and when the user presses the confirmation button K4 displayed as “Return (does not rotate)”, It is set not to rotate the image of the 11th page. When the confirmation button K3 or K4 is pressed on the confirmation screen of FIG. 24, the screen returns to the confirmation screen of FIG.

  Then, on the confirmation screen of FIG. 16, when the confirmation button K1 displayed as “Yes (rotate all at once)” is pressed, the approximate images of the pages whose check boxes CK are “■” are rotated all at once. And displayed on the display unit 62. On the other hand, when the confirmation button K2 displayed as “No” is pressed, the image is not rotated and the display of the confirmation screen is terminated.

  Thus, in the present embodiment, a warning is given that there is a non-approximate image that is not a rotation target, and the user is allowed to set whether to rotate each non-approximate image. As a result, even an image that does not approximate the processing target image is subject to rotation according to the user's instruction, and the degree of freedom of selection increases.
