Description

[Technical field]

[0001] The present invention relates to an information processing apparatus, a control method thereof, a program, and an image forming system. [Background technology]

[0002] Conventionally, there is known an image forming system that uses an inspection device to inspect whether an image formed on a recording medium by an image forming device based on RIP data is formed in accordance with the image represented by the RIP data. The inspection device compares the RIP data as reference data with scan data obtained by reading the image formed on the recording medium with a sensor such as a scanner, and inspects the image formed on the recording medium based on the comparison result.

[0003] Patent Document 1 describes that when the inspection result is NG, the following are displayed: the print job in general, the jobs in general that were NG, and the NG parts and types of NG (such as dots or streaks) for a specific printed matter among the NG jobs. This allows the user to instantly grasp the approximate NG parts for a specific printed matter of a job that has been determined to be NG, and shortens the time required to visually confirm the NG parts on the printed matter.

[0004] [Patent Document 1] Patent Publication No. 2021-27582 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned Patent Document 1, when the print quality is NG, the approximate location and type of the abnormality can be grasped instantly, but the degree of the abnormality cannot be determined instantly. Generally, when the print quality is NG, the user checks the degree of the abnormality and judges whether it is OK or NG. If the degree of the abnormality cannot be determined instantly, it takes time to check the degree of the abnormality, which reduces usability.

[0006] In view of the above-mentioned problems, an object of the present invention is to improve usability when a user judges the degree of an abnormality in a printed matter. [Means for solving the problem]

[0007] The present invention is, for example, an information processing device comprising a first acquisition means for acquiring reference image data used for printing a printed material, a second acquisition means for acquiring an inspection result of image quality by an inspection means comparing read image data obtained by reading the printed material with the reference image data, and a display control means for displaying an inspection result screen on a display unit according to the inspection result, wherein the inspection result screen includes a first area for displaying an entire image corresponding to the read image data for a specified page among the pages read from the printed material, and a second area for displaying, in association with each other, a normal enlarged image obtained by enlarging a normal image based on the reference image data and an abnormal enlarged image obtained by enlarging an abnormal image based on the read image data for each abnormal location contained in the entire image.

[0008] The present invention also comprises, for example, a first acquisition means for acquiring reference image data used for printing a printed matter, an image forming means for outputting a printed matter using the reference image data, a reading means for reading the printed matter, an inspection means for inspecting image quality by comparing the read read image data with the reference image data, and a display control means for displaying an inspection result screen on a display unit according to the inspection result by the inspection means, wherein the inspection result screen includes a first area for displaying an entire image corresponding to the read image data for a specified page among the pages read from the printed matter, and a second area for displaying, in association with each other, a normal enlarged image obtained by enlarging a normal image based on the reference image data and an abnormal enlarged image obtained by enlarging an abnormal image based on the read image data for each abnormal location contained in the entire image.

[0011] Hereinafter, the embodiments will be described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims. Although the embodiments describe a number of features, not all of these features are essential to the invention, and the features may be combined in any manner. Furthermore, in the attached drawings, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0012] <First embodiment> <Image forming system configuration> A first embodiment of the present invention will be described below. First, an example of the configuration of an image forming system including an inspection device according to this embodiment will be described with reference to Fig. 1. The image forming system 1 includes an operation unit 200, a printer 300 as an image forming unit, a controller 400, an inspection device 500 as an image inspection unit, a stacker 600, and a finisher 700 as a post-processing unit.

[0013] The operation unit 200 is a user interface equipped with an input interface and an output interface. The input interface includes devices such as input keys and a touch panel. The output interface includes devices such as a display and a speaker. The operation unit 200 transmits instructions and data input from the input interface to the controller 400. In addition, the operation unit 200 outputs information from the output interface in accordance with instructions from the controller 400.

[0014] The controller 400 corresponds to an information processing device, and controls the operations of the printer 300, the inspection device 500, the stacker 600, and the finisher 700 based on instructions and data input from the operation unit 200, or instructions and data acquired from an external device via a network. For example, the controller 400 transmits an image formation instruction to the printer 300 when performing image formation. The details of the controller 400 will be described later. The controller 400 may be configured integrally with the printer 300 and provided as an image forming device. The controller 400 may also be provided with an inspection function of the inspection device 500, which will be described later. In this case, at least the printer 300, the controller 400, and the inspection device 500 may be configured integrally and provided as an image forming system.

[0015] (Printer) A configuration example of a printer will be described. The printer 300 of this embodiment will be described as an example of a color image forming device that prints color images on paper. Note that the present invention is not intended to be limited to a color image forming device, and may be an image forming device that prints monochrome images. In that case, the type of abnormality that is the inspection item may be appropriately changed. The printer 300 includes image forming units Y, M, C, and K, an intermediate transfer body 306, a transfer unit 307, a fixing unit 308, paper feed cassettes 311 and 312, and a paper feed mechanism. The image forming unit Y forms a yellow (Y) image. The image forming unit M forms a magenta (M) image. The image forming unit C forms a cyan (C) image. The image forming unit K forms a black (K) image. The intermediate transfer body 306 is transferred with the images of each color formed by the image forming units Y, M, C, and K superimposed on each other.

[0016] Transfer unit 307 transfers the image carried on intermediate transfer body 306 onto paper. Fixing unit 308 fixes the image transferred onto the paper onto the paper. Each of image forming units Y, M, C, and K has the same configuration and forms an image by the same operation. Here, the configuration of image forming unit Y will be described, and descriptions of the configurations of image forming units M, C, and K will be omitted.

[0017] The image forming unit Y includes a photosensitive drum 301Y, a charger 302Y, an exposure device 303Y, and a developing device 304Y. The photosensitive drum 301Y is a drum-shaped photosensitive body having a photosensitive layer on its surface. The photosensitive drum 301Y rotates around the drum axis in the direction of the arrow R during operation. The charging device 302Y uniformly charges the surface of the rotating photosensitive drum 301Y. The exposure device 303Y acquires image data representing a yellow image from the controller 400, and outputs a laser beam in accordance with the image data. The laser beam output from the exposure device 303Y scans the surface of the charged photosensitive drum 301Y in the drum axis direction. By scanning the surface of the rotating photosensitive drum 301Y with the laser beam, an electrostatic latent image corresponding to the yellow image data is formed on the surface of the photosensitive drum 301Y. The developing device 304Y contains a yellow developer (e.g., toner) and develops the electrostatic latent image formed on the photosensitive drum 301Y with the developer. As a result, a yellow image is formed on the surface of the photosensitive drum 301Y. The developing device 304Y is configured so that developer can be constantly replenished from a toner cartridge (not shown). Similarly, a magenta image is formed on the photosensitive drum 301M of the image forming station M. A cyan image is formed on the photosensitive drum 301C of the image forming station C. A black image is formed on the photosensitive drum 301K of the image forming station K.

[0018] The intermediate transfer body 306 is an endless belt member, and rotates in a clockwise direction in the figure. The intermediate transfer body 306 is in contact with each of the photosensitive drums 301Y, 301M, 301C, and 301K. As the intermediate transfer body 306 rotates, images of each color are transferred from each of the photosensitive drums 301Y, 301M, 301C, and 301K in order to be superimposed on each other. As a result, a full-color image is formed on the intermediate transfer body 306. The intermediate transfer body 306 conveys the full-color image it carries to a transfer unit 307 by rotating.

[0019] Paper is stored in paper feed cassettes 311 and 312, and is transported from paper feed cassettes 311 and 312 to transfer unit 307 by a feeding mechanism. The paper is transported according to the timing at which the image carried on intermediate transfer body 306 is transported to transfer unit 307. Transfer unit 307 transfers the image from intermediate transfer body 306 to the paper. A cleaner 309 is disposed downstream of transfer unit 307 in the rotation direction of intermediate transfer body 306. Cleaner 309 removes developer remaining on intermediate transfer body 306 after transfer.

[0020] The paper onto which the image has been transferred is transported from transfer unit 307 to fuser 308. Fuser 308 includes a heater and a pressure roller. Fuser 308 melts and fuses the image onto the paper by heat from the heater and pressure from the pressure roller. Downstream of fuser 308 in the paper transport direction are transport paths 313, 314, and 315, a double-sided transport path 316, and discharge rollers 317.

[0021] The paper that has passed through the fixing unit 308 is once transported from transport path 313 to transport path 314. After the rear end of the paper has passed through transport path 313, the transport direction is reversed and the paper is transported from transport path 315 to discharge rollers 317. Through this transport, the paper is discharged from printer 300 by discharge rollers 317 with the side on which the image has been formed facing downward (face down). The printed matter, which is the paper after the image has been formed and discharged from printer 300 by discharge rollers 317, is delivered to inspection device 500.

[0022] When double-sided printing is to be performed on the paper, the paper transported to transport path 314 has its rear end pass through transport path 313, and is then transported to double-sided transport path 316. The paper is transported again to transfer unit 307 via double-sided transport path 316. By passing through double-sided transport path 316, the side of the paper on which the image has been formed is inverted. The inverted side of the paper is subjected to an image transfer process by transfer unit 307 and a fixing process by fixing device 308. As a result, an image is formed on that side as well. The paper with images formed on both sides is discharged from printer 300 by discharge rollers 317 as a printed matter, and is handed over to inspection device 500.

[0023] (Inspection equipment) Next, a configuration example of the inspection device will be described. The inspection device 500 compares the reference image data used for printing the printed matter with the read image data obtained by reading the printed matter to inspect the image quality. The inspection device 500 includes a conveying path 501, an inspection control unit 510, a first reading unit 5051a, a second reading unit 5051b, running reading glasses 5053a and 5053b, conveying rollers 502 and 503, and a paper detection sensor 504.

[0024] The inspection control unit 510 controls the operation of the inspection device 500 under the control of the controller 400. Details of the inspection control unit 510 will be described later. The first reading unit 5051a and the second reading unit 5051b are disposed in positions facing each other across a conveying path 501. Conveying rollers 502 and 503 convey the printed material.

[0025] The inspection device 500 detects the printed material conveyed on the conveying path 501 by the paper detection sensor 504, and reads the printed image by the first reading unit 5051a and the second reading unit 5051b. The first reading unit 5051a and the second reading unit 5051b transmit the reading results of the printed material to the inspection control unit 510. The inspection control unit 510 performs a quality inspection of the image printed on the printed material based on the reading results of the printed material. Since the first reading unit 5051a and the second reading unit 5051b are arranged opposite each other via the conveying path 501, the images printed on both sides of the printed material are read in one conveyance of the printed material. The printed material from which the images have been read is conveyed from the inspection device 500 to the stacker 600.

[0026] (Stacker, Finisher) An example of the configuration of the stacker and the finisher will be described. The stacker 600 includes a large-capacity tray 610 and a purge tray 620. The stacker 600 discharges printed materials to any of the large-capacity tray 610, the finisher 700, and the purge tray 620 based on instructions from the controller 400 and the results of the quality inspection by the inspection control unit 510. That is, the printed materials can be classified and discharged according to the results of the quality inspection. For example, printed materials that have been determined to be NG in the quality inspection may be discharged to the purge tray 620, and printed materials that have been determined to be OK in the quality inspection may be discharged to the large-capacity tray 610 or the finisher 700.

[0027] The finisher 700 includes a printed matter transport section 710 including a plurality of transport rollers and a transport path, an upper discharge tray 701, a middle discharge tray 702, and a lower discharge tray 703. The printed matter transport section 710 includes switching mechanisms 711 and 712 for switching the discharge destination of the printed matter. The finisher 700 sequentially takes in the printed matter from the stacker 600, and discharges the printed matter to any one of the upper discharge tray 701, the middle discharge tray 702, and the lower discharge tray 703 in response to an instruction from the controller 400. The finisher 700 may also include a configuration for performing post-processing such as stapling to bind multiple printed matters together, bookbinding of the bound printed matters, and trimming of the bound printed matters.

[0028] <Controller> Next, an example of the configuration of the controller 400 according to this embodiment will be described with reference to Fig. 2. The storage 4100 is a large-capacity storage device such as a hard disk drive (HDD) or a solid state drive (SSD).

[0029] In addition to the printer 300, the inspection device 500, and the operation unit 200, the storage 4100 and the power supply control unit 4500 are connected to the controller 400. The controller 400 includes an HDD I / F 4318, an operation unit I / F 4306, a power supply control I / F 4308, an inspection unit I / F 4317, a printer communication I / F 4307, and a printer I / F 4316 as interfaces with each of these connected units. The controller 400 also includes a communication I / F 4305 for communicating with an external device via a network. The storage I / F 4318, the operation unit I / F 4306, the power supply control I / F 4308, the inspection unit I / F 4317, the printer communication I / F 4307, and the communication I / F 4305 are connected to a system bus 4319.

[0030] The controller 400 includes a central processing unit (CPU) 4301, a read only memory (ROM) 4302, and a random access memory (RAM) 4303. The CPU 4301 controls the operation of the image forming system 1 by executing a computer program stored in the ROM 4302. The RAM 4303 provides a working area for the CPU 4301 to execute processing. The RAM 4303 is also used as an image memory for temporarily storing image data and the like. The CPU 4301, the ROM 4302, and the RAM 4303 are also connected to a system bus 4319. A non-volatile RAM (NVRAM) 4304 and a timer 4309 are also connected to the system bus 4319. The NVRAM 4304 stores various control parameters. The timer 4309 holds the current time and monitors the passage of a set time.

[0031] The operation unit I / F 4306 controls communication with the operation unit 200. The operation unit I / F 4306 accepts inputs such as print jobs, commands, and print settings from the operation unit 200 to the controller 400, and transmits them to the CPU 4301. The operation unit I / F 4306 displays various screens and the status of the image forming system 1 on the operation unit 200 under the control of the CPU 4301. The printer communication I / F 4307 controls communication with the printer 300 under the control of the CPU 4301. The power supply control I / F 4308 instructs the power supply control unit 4500 to supply / stop various types of power under commands from the CPU 4301. The power supply control unit 4500 supplies power to the printer 300. The inspection unit I / F 4317 controls communication with the inspection device 500 under the control of the CPU 4301. The storage I / F 4318 controls communication with the storage 4100 under the control of the CPU 4301 .

[0032] The communication I / F 4305 is connected to a network such as a LAN (Local Area Network) and performs communication control such as sending and receiving e-mails and inputting and outputting PDL data from external devices. The communication I / F 4305 also has an NVRAM (not shown) that holds various parameters related to communication control such as a MAC address.

[0033] The system bus 4319 is connected to an image bus 4311 via an image bus I / F 4310. The bus I / F 4310 is a bridge that connects the system bus 4319 and an image bus 4311 for transferring image data to the printer 300. A printer I / F 4316, an image compression unit 4312, an image rotation unit 4313, and a RIP (Raster Image Processor) 4314 are connected to the image bus 4311.

[0034] An image compression unit 4312 performs compression and decompression processing for JPEG, JBIG, MMR, MH, etc. An image rotation unit 4313 performs image rotation processing. A RIP 4314 expands PDL code into a bitmap raster image. A printer I / F 4316 transmits image data to the printer 300. This image data is generated by the controller 400 performing image processing for the printer 300, such as correction for the printer 300 and resolution conversion, on image data for print output.

[0035] <Inspection Control Unit> Next, a configuration example of the inspection control unit 510 of the inspection device 500 according to this embodiment will be described with reference to Fig. 3. The inspection control unit 510 controls the operations of the first reading unit 5051a and the second reading unit 5051b.

[0036] The inspection control unit 510 performs processes such as analysis of the reading results of the first reading unit 5051a and the second reading unit 5051b, operation control of the inspection device 500, and communication with the controller 400. The inspection control unit 510 is also connected to the controller 400 and a storage 5011 for storing a position deviation correction profile and the like.

[0037] The inspection control unit 510 includes a CPU 5001, a ROM 5002, a RAM 5003, a storage I / F 5004, a motor control unit 5009, a read image processing unit 5008, an image processing unit 5006, an RTC 5012, a host I / F 5007, and a sensor control unit 5010. Each unit is connected to a system bus 5005. The read image processing unit 5008 is connected to a first reading unit 5051a via a first reading I / F 5052a, and is connected to a second reading unit 5051b via a second reading I / F 5052b.

[0038] The RTC 5012 is a real-time clock and holds the current time with high accuracy. The host I / F 5007 controls communication with the inspection unit I / F 4317 of the controller 400. When the inspection control unit 510 and the controller 400 communicate with each other, data is transmitted and received between the host I / F 5007 and the inspection unit I / F 4317. For example, the host I / F 5007 acquires image data used in the image forming operation of the printer 300 from the controller 400. The storage 5011 is a large-capacity storage device such as an HDD or SSD. The image data is stored in the storage 5011 as reference image data, which will be described later.

[0039] The CPU 5001 executes a computer program stored in the ROM 5002 to control the operation of the inspection device 500. The RAM 5003 provides a working area for the CPU 5001 to execute processing. The storage I / F 5004 controls communication with a storage 5011 connected to the inspection control unit 510.

[0040] The read image processing unit 5008, under the control of the CPU 5001, acquires the read result of the image of the printed matter from the first reading unit 5051a via the first reading I / F 5052a. Also, under the control of the CPU 5001, the read image processing unit 5008 acquires the read result of the image of the printed matter from the second reading unit 5051b via the second reading I / F 5052b. Under the control of the CPU 5001, the read image processing unit 5008 performs magnification processing, gamma correction processing, etc. on the read result (read data) of the image of the printed matter acquired from the first reading unit 5051a and the second reading unit 5051b to generate read image data. The generated read image data is stored in the RAM 5003. The first reading unit 5051a and the second reading unit 5051b have a sensor array and can read the entire area of ​​the printed matter transported on the transport path 501. The first reading unit 5051a reads an image on a first side of a printed material, and the second reading unit 5051b reads an image on a second side of the printed material.

[0041] The first reading unit 5051a and the second reading unit 5051b are composed of a light emitting unit and a light receiving unit. The light emitting unit is composed of, for example, a white LED (Light Emitting Diode). The light receiving unit is composed of, for example, a CMOS sensor with an RGB color filter. The light emitting unit irradiates light onto the printed material transported on the transport path 501 under the control of the CPU 5001. The light receiving unit receives the light reflected by the printed material by separating it into three RGB color components using a color filter, and outputs read data as the light reception result (read result). The read data is transmitted to the read image processing unit 5008.

[0042] The motor control unit 5009 controls the operation of various motors provided in the inspection device 500 under the control of the CPU 5001. The sensor control unit 5010 controls the operation of various sensors provided in the inspection device 500 under the control of the CPU 5001, and notifies the CPU 5001 of the detection results of the sensors. The image processing unit 5006 compares image data (hereinafter referred to as "reference image data") stored in the storage 5011 with the read image data stored in the RAM 5003 under the control of the CPU 5001 to inspect the quality of the printed matter. The reference image data is image data used for image formation by the printer 300, and is stored in the storage 5011. Alternatively, the reference image data may be an image obtained by reading a reference image in advance before the quality inspection is performed. During the comparison, the image processing unit 5006 performs a correction process on the reference image data using parameters based on calibration, which will be described later.

[0043] <Settings screen> Next, an example of a setting screen displayed on the operation unit 200 according to this embodiment will be described with reference to Fig. 4 and Fig. 5. Fig. 4 shows a print setting screen 4000 displayed on the display of the operation unit 200 during inspection printing processing involving quality inspection of printed matter. The operator uses the operation unit 200 to set quality inspection items and instructs execution of the inspection printing process using these operation screens displayed on the display.

[0044] The print setting screen 4000 is a setting screen for printing processing, and allows the operator to set whether or not to perform quality inspection. The operator can select the print color (color / black and white), the paper type, set the destination of the printed matter, select calibration execution, and the like by operating buttons B101 to B106 displayed on the print setting screen 4000. The operator can transition from the print setting screen 4000 to the inspection setting screen 5000 shown in FIG. 5 by operating the inspection setting button B101. When the print start button B102 is operated, the formation of the printed matter is started without performing quality inspection by the inspection device 500. When the cancel button B103 is operated, the contents set on the print setting screen 4000 are canceled, and a predetermined initial screen is displayed on the display of the operation unit 200. The destination of the printed matter is set by the output tray setting button B104. By operating the paper selection button B106, it is possible to confirm and change the size and basis weight of the paper placed in the paper feed cassettes 311 and 312, and to specify the cassette from which paper is to be fed.

[0045] FIG. 5 shows an inspection setting screen 5000 displayed on the display of the operation unit 200 when the button B101 is selected in FIG. 4. The inspection setting screen 5000 is a setting screen that accepts an instruction from a user to set an inspection area where an inspection such as a quality inspection is performed by the inspection device 500. In the figure, an area B401 is a print image and inspection setting area display section. In the area B401, an original image (i.e., a reference image) in a print job is displayed, and the inspection area can be set by selecting a predetermined part of the image display area of ​​the area B401 while the user selects an inspection area type button shown in the buttons B402a to B402d. The selection method may be an operation of selecting a predetermined object present in the image displayed in the area B401. Alternatively, the inspection area may be selected by tracing the inspection area on a touch panel or by dragging the area via a pointing device. In the area B401, as shown in FIG. 5, the selected inspection area is displayed surrounded by a different frame line, for example, a solid line, a dotted line, or a dashed line, for each type.

[0046] Buttons B402a to B402d are buttons that represent the types of inspection areas. Button B402a is a priority inspection area button for setting an area where high-precision inspection is performed. Button B402b is a standard inspection area button for setting an overall inspection level. Button B402c is an inspection exclusion area button for specifying an area where inspection is not performed. Button B402d is a character inspection area button for recognizing and inspecting characters, barcodes, etc. Here, four buttons are displayed to be selectable, but there is no intention to limit the number of buttons displayed, and the number displayed may correspond to the type of abnormality to be inspected.

[0047] Buttons B403a, B403b, and B403d are inspection level setting buttons for setting the inspection accuracy stepwise, for example, from level 1 to 5, for each type of inspection area. The user can set the inspection level for each area of ​​buttons B402a and B402b. Here, inspection level 1 has the lowest inspection accuracy, and the inspection accuracy increases as the inspection level number increases. Higher inspection accuracy means that the conditions for determining that there is no abnormality become stricter.

[0048] A button B405 is an inspection start button, and when the user selects this button, the inspection print process is started. A button B406 is a button for returning to the original screen, and when the user selects this button, the inspection setting process is canceled and the screen returns to the print setting screen 4000.

[0049] In the inspection setting screen 5000, for example, the button B402a is selected, and the area where high-precision inspection is required is selected by using a mouse or a touch panel, etc., so that the area where high-precision inspection is performed can be arbitrarily selected. In the example shown in FIG. 5, a high-precision inspection is performed on shapes such as circles and crosses. In addition, since high-precision inspection is not required for cylinders and triangles, they are set as areas excluded from inspection. Therefore, compared to the case where the entire image is inspected without such selection, it is possible to reduce the memory and processing power required for the inspection. In addition, by setting the inspection level in stages, for example, from level 1 to level 5, it is possible to reduce the memory and processing power required for the inspection compared to the case where inspection is always performed with the highest level of accuracy.

[0050] <Result display screen> Next, referring to FIG. 6, an example of the inspection result screen 6000 when the inspection result of the printed matter according to the present embodiment is NG will be described. In the present embodiment, an example in which the inspection result screen 6000 is displayed on the operation unit 200 by the CPU 4301 of the controller 400 will be described. However, this does not limit the present invention, and the inspection result screen 6000 may be displayed on the display unit of the inspection device 500 or another device, for example, an external device connected via a network. In this case, the CPU 4301 of the controller 400 transmits screen information for displaying the inspection result screen 6000 to the inspection device 500 or the external device. The CPU 4301 is an example of a display control means or a transmission means. B601 is an area (first area) that displays the entire image determined to be NG in the print inspection and the abnormal part determined to be NG. Meanwhile, B602 and B603 described below are areas (second areas) that display the normal enlarged image and the abnormal enlarged image.

[0051] B602a (area surrounded by a dotted line) included in the area B601 is an indication showing the position of the first abnormality in the whole image judged as NG in the print inspection. Also, B602b shows an enlarged image of the normal state (i.e., the reference image) at the position of B602a. Here, the blank indicates the image at the normal state. B602c shows the abnormally enlarged image at the position of B602a. In this way, the normal enlarged image and the abnormally enlarged image are displayed adjacent to each other, so that the degree of the abnormality can be easily confirmed. That is, according to this embodiment, for each abnormal part included in the whole image, a normal enlarged image obtained by enlarging a normal image based on the reference image data and an abnormally enlarged image obtained by enlarging an abnormal image based on the read image data are displayed in association with each other. Here, as an example, the normal enlarged image and the abnormally enlarged image are displayed side by side. Of course, any form of display may be used as long as the method of displaying the images in association with each other is used.

[0052] The magnification ratio of B602b is the same as that of B602c. The magnification ratio may be changeable in B605a. Specifically, the magnification ratio of the abnormally enlarged image and the normal enlarged image can be changed by operating the operation button B605b left and right. For example, the image may be reduced by operating the operation button B605b left, and may be enlarged by operating the operation button B605b right. The operation button is an example of an operation object, and an example of a slide bar is shown here, but other types of operation objects may be used. For example, the operation object may be an operation object that allows a numerical value of the magnification ratio to be input. When changing the magnification ratio, it is desirable to change the normal enlarged image and the abnormally enlarged image in the same way.

[0053] Here, an example is shown in which the magnification ratios of all the normal enlarged images and the abnormally enlarged images are changed at the same time. However, an operation object for changing the magnification ratio as shown in B602a may be provided for each set of a normal enlarged image and a corresponding abnormally enlarged image, so that the magnification ratio can be changed for each set. Furthermore, the scale of the entire image displayed in area B601 may be made changeable. In this case, the magnification ratios of each enlarged image may be changed in conjunction with the change in the magnification ratio of the entire image. Note that, like the magnification ratio before the enlargement change, it is desirable to make the magnification ratio of each enlarged image larger than the magnification ratio of the entire image.

[0054] In addition, when enlarging both the entire image and the enlarged image, the enlargement may be centered on the part (abnormal part) that the user focuses on. This makes it possible to prevent the abnormal part from being hidden in the enlarged image. Alternatively, the center position of the image may be changed in response to a drag operation of a pointing device or the like. This makes it possible to change the enlargement ratio of the image in accordance with the user's intention.

[0055] B603a (region surrounded by a dashed line) included in area B601 is an indication showing the position of a second abnormality in the entire image determined to be NG in the print inspection. Also, B603b shows a normal image at the position of B603a. Here, blank spaces indicate normal images. B603c shows an abnormally enlarged image at the position of B603a. The magnification ratio of B603b is assumed to be the same as that of B603c. As with B602, the magnification ratio may be changeable by a user operation.

[0056] B604 is a scroll bar (operation object) for switching pages of jobs that have been determined to be NG in the print inspection, and pages of NG images can be switched by moving the bar left and right. Areas B602 and B603 that display enlarged images of abnormalities and normal images also switch to display corresponding images as pages are switched. Note that for the area that displays the enlarged images, if the number of images that can be displayed at one time exceeds the upper limit depending on the location of the abnormality, a scroll bar is displayed, and enlarged images of undisplayed abnormal locations are displayed by operating the bar. B605 is an inspection end button that the user can operate after checking the print inspection to end the print inspection.

[0057] Thus, according to this embodiment, when a NG judgment is made, the entire image B601 judged as NG in the print inspection for each NG image, the normal enlarged image (B602b, B603b), and the abnormal enlarged image (B602c, B603c) are displayed simultaneously on one screen. Therefore, the user can easily check the abnormal part from the NG print image discharged to each discharge destination. In addition, since the normal enlarged image (B602b, B603b) and the abnormal enlarged image (B602c, B603c) can be compared simultaneously, it is possible to shorten the judgment of whether the abnormality is acceptable or not. In general, when a NG judgment is made, it is possible to shorten the time until the acceptance judgment and the optimization of the inspection level, and to reduce the downtime of the device. As a result, it is possible to improve the usability when the user judges the degree of abnormality in the print.

[0058] In addition, when there are multiple images that are judged as NG, it goes without saying that by operating B604, the whole image judged as NG in the print inspection is switched to the next image, and at the same time, a normal enlarged image and an abnormal enlarged image corresponding to the abnormal part of each image are displayed in conjunction with each other. Also, the linking between B602a and B602b, B602c, or B603a and B603b, B603c is distinguished by the shape of the frame line, i.e., a solid line, a dotted line, a dashed line, etc., but is not limited to this. For example, the color of the frame line may be used to distinguish them.

[0059] <Print inspection process flow> Next, the procedure of the inspection printing process in this embodiment will be described with reference to Fig. 9. Fig. 9 illustrates the processes executed by the CPU 4301 of the controller 400 and the CPU 5001 of the inspection device 500. The processes are executed when the user selects the print start button B102 in Fig. 4. The processes described below are realized, for example, by the CPU 4301 of the controller 400 and the CPU 5001 of the inspection device 500 reading out programs stored in the ROM and HDD, respectively, into the RAM and executing them.

[0060] In S901, the CPU 4301 of the controller 400 accepts the selection of the print start button B102 via the operation unit 200, and transmits job information including paper information used in printing, inspection settings, discharge destination, etc. to the inspection device 500. Meanwhile, in S902, the CPU 5001 of the inspection device 500 receives the job information transmitted from the controller 400.

[0061] Next, in S903, the CPU 5001 of the inspection device 500 judges whether or not the print job is a job that requires inspection from the job information received in SS902 after receiving a response of the job information from the controller 400. If it is a job that requires inspection (S903: Yes), the process proceeds to S904, where the CPU 5001 of the inspection device 500 sends a request to the controller 400 to send reference image data for inspection judgment, and transitions to S905. On the other hand, if the job does not require inspection (S903: No), the process transitions to S907.

[0062] In S905, the CPU 4301 of the controller 400 transmits the document image data of the print job as reference image data to the inspection device based on a request to transmit reference image data from the inspection device 500. Next, in S906, the CPU 5001 of the inspection device 500 receives the reference image data from the controller 400 and stores it in the storage 5011. Furthermore, in S907, the CPU 5001 of the inspection device 500 notifies the controller 400 that preparation for the print job is complete upon completion of reception of the reference image data.

[0063] Next, in S908, the CPU 4301 of the controller 400 executes print processing together with the printer unit based on the preparation completion notification from the inspection device 500. After that, in S909, the CPU 4301 of the controller 400 determines whether there is a next page and continues printing until the set number of sheets for the print job are printed. When printing is completed, the process transitions to S914.

[0064] On the other hand, after sending the preparation completion notice in S907, in S910, the CPU 5001 of the inspection device 500 uses the paper detection sensor 504 to determine whether or not a paper sheet has arrived at the conveying path 501 of the inspection device 500. If the paper sheet has not arrived (S910: No), the CPU 5001 of the inspection device 500 waits until the paper sheet is sent. If it is determined that the paper sheet has arrived (S910: Yes), in S911, the CPU 5001 of the inspection device 500 causes the first reading unit 5051a and the second reading unit 5051b to sequentially read the sent paper sheets. Furthermore, the CPU 5001 instructs the image processing unit 5006 to perform a comparison process with the reference image data received in S906. As a result, the image processing unit 5006 executes the comparison process, and image inspection is performed.

[0065] Next, in S912, the CPU 5001 of the inspection device 500 stores the inspection result obtained by the comparison in the image processing unit 5006 in the RAM 5003. After that, in S913, the CPU 5001 of the inspection device 500 determines whether or not the next page is to be printed from the received job information, and if there is a next page (S913: Yes), executes the process again from S910 to continue the inspection process. If there is no next page (S913: No), the process proceeds to S914.

[0066] In S914, the CPU 5001 of the inspection device 500 transmits the inspection results held in S912 to the controller 400. In S915, the CPU 4301 of the controller 400 receives the inspection results transmitted from the CPU 5001 of the inspection device 500. Next, in S916, the CPU 4301 of the controller 400 determines whether or not there is any NG from the received inspection results, and if there is NG (S916: Yes), the process proceeds to S917, and if there is no NG (S916: No), the print inspection process ends. In S917, the CPU 4301 of the controller 400 controls the operation unit 200 to display the inspection result screen 6000 described with reference to FIG. 6 on the operation unit 200. After the user checks the abnormality, the CPU 4301 of the controller 400 terminates the print inspection process by selecting the inspection end button B605.

[0067] Although an example in which the controller 400 and the inspection device 500 cooperate to execute the inspection process has been described here, there is no intention to limit the configuration of this image forming system, and other configurations may be used. For example, the controller 400 may be provided as an image forming device integrated with the printer 300. Furthermore, the inspection device 500 may also be provided as an integrated device. Also, a configuration in which an inspection result screen is displayed on the display unit of the inspection device 500 or the display unit of an external device may be used.

[0068] As described above, the information processing device according to the present embodiment acquires reference image data used for printing a printed matter, and acquires an inspection result of image quality by comparing the read image data obtained by reading the printed matter with the reference image data by the inspection unit. The information processing device also displays an inspection result screen on the display unit according to the inspection result. The inspection result screen includes a first area that displays an entire image corresponding to the read image data for a specific page among the pages read from the printed matter. Furthermore, the inspection result screen includes a second area that displays, in association with each abnormal portion included in the entire image, a normal enlarged image obtained by enlarging a normal image based on the reference image data and an abnormal enlarged image obtained by enlarging an abnormal image based on the read image data. As a result, when the printed matter inspection is NG, the entire image determined to be NG in the printed matter inspection, the normal enlarged image, and the abnormal enlarged image are simultaneously displayed for each NG image, thereby favorably supporting the user in determining whether the abnormality in the printed matter is acceptable, shortening the time required for optimizing the inspection level, and reducing the downtime of the device. As a result, the usability when the user determines the degree of abnormality in the printed matter can be improved.

[0069] <Second embodiment> The second embodiment of the present invention will be described below. The device configuration of this embodiment is the same as that of the first embodiment, and only the characteristics of the operation unit screen when the print inspection is NG are different, so only the differences will be described here. In this embodiment, an example will be described in which the inspection results are displayed for an abnormality of a different type from the abnormality inspection type described in the first embodiment.

[0070] <Test result image> An example of an inspection result screen 7000 when the inspection result of a printed matter according to this embodiment is NG will be described with reference to Fig. 7. B701 is an area that displays the entire image that has been determined to be NG in the print inspection and the abnormal portion that has been determined to be NG.

[0071] B702a (area surrounded by a dotted line) included in area B701 is an indication showing the position of the first abnormality in the entire image that was determined to be NG in the print inspection. Also, B702b shows an enlarged image of the position of B702a when normal. Here, blank spaces indicate that the image is normal. B702c shows an abnormally enlarged image of the position of B702a. In this way, by displaying the normal enlarged image and the abnormally enlarged image adjacent to each other, the degree of the abnormality can be easily confirmed.

[0072] The magnification ratio of B702b is the same as that of B702c. The magnification ratio may be changeable in B706a. Specifically, the magnification ratios of the abnormally enlarged image and the normally enlarged image can be changed by operating the operation button B706b left and right. The operation and modification of the magnification ratio are similar to those of B605a in the first embodiment, and therefore detailed description will be omitted.

[0073] B703a (the area "surrounded" by a large dotted line) included in area B701 is an indication showing the location of a second abnormality in the entire image that was judged to be NG in the print inspection. In this embodiment, the second abnormality is an abnormality that occurred in the area specified in the character inspection area by operating button B402d in Figure 5, which is the character inspection area. B703b shows the normal character string at the position of B703a, and B703c shows an enlarged image of the abnormality at the position of B703a. B703d shows the character recognition (decode) result of the character inspection area. Here, the character recognition result is "106", which is different from the normal value of "105", so it can be easily seen that an abnormality has occurred in the image formation of "5".

[0074] According to this embodiment, for the second abnormality, which is an abnormality in character inspection, in addition to simultaneously displaying the normal character string and the abnormal image, the character recognition (decoding) result is also displayed. In this case, the user can instantly recognize from B703c that the character recognition (decoding) result is different from the normal character string as a result of the character being misrecognized due to the presence of an abnormality such as a dot superimposed on the character.

[0075] B704 is a scroll bar for switching pages of jobs that have been determined to be NG in the print inspection, and it is possible to switch pages of NG images by moving the bar left and right. Also, B705 is an inspection end button, which the user can operate after checking the print inspection to end the print inspection.

[0076] Thus, according to this embodiment, when an NG judgment is made, the entire image B701 judged as NG in the print inspection for each NG image, and the normal enlarged image (B702b) and the abnormal enlarged image (B702c) for the first abnormality are displayed simultaneously. Furthermore, for the second abnormality, the normal character string (B703b), the abnormal enlarged image (B703c), and the character recognition (decoded) result (B703d) of the character inspection area are displayed simultaneously. That is, in this embodiment, the information displayed simultaneously is switched depending on the inspection type. The information suitable for isolating the cause of the NG judgment differs depending on the inspection type, and an inspection result screen is provided that displays them simultaneously. As a result, even in a job with an expanded inspection type, the user can shorten the time from the NG judgment to the acceptance judgment and the optimization of the inspection level, thereby reducing the downtime of the device. As a result, the usability when the user judges the degree of abnormality in the print can be improved.

[0077] <Third embodiment> The third embodiment of the present invention will be described below. The device configuration of this embodiment is the same as that of the first and second embodiments, and only the features of the inspection result screen when a NG judgment is made are different, so only the differences will be described here. In this embodiment, an example will be described in which, when the number of abnormality occurrence locations exceeds the upper limit that can be displayed at one time, enlarged images of all abnormality locations are displayed using a scroll bar.

[0078] <Test result screen> 8, an example of inspection result screens 8000 and 8100 when the inspection result of a printed matter according to this embodiment is NG will be described. In the inspection result screen 8000, B801 is an area that displays the entire image that has been determined to be NG in the print inspection and the abnormal portion that has been determined to be NG.

[0079] B802a (area surrounded by a dotted line) included in area B801 is an indication showing the position of the first abnormality in the entire image judged to be NG in the print inspection. Also, B802b shows an enlarged image of the position of B802a when normal. Here, blank spaces indicate that the image is normal. B802c shows an enlarged image of the abnormality at the position of B802a. B808a and operation button B808b are the same as in the first embodiment, and therefore description thereof will be omitted.

[0080] B803a (area surrounded by a dashed line) included in area B801 indicates the position of a second abnormality in the entire image that was determined to be NG in the print inspection. B803b indicates an enlarged image of the position of B803a when normal. B803c indicates an enlarged image of the abnormality at the position of B803a.

[0081] B804a (region surrounded by a large dotted line) included in area B801 is an indication showing the position of a third abnormality in the entire image that was determined to be NG in the print inspection. Detailed information such as a character string in a normal state and an enlarged image in an abnormal state corresponding to B804a is hidden on the inspection result screen 8000 because it cannot be displayed on the inspection result screen 8000.

[0082] B805 is a scroll bar for switching pages of jobs that have been determined to be NG in the print inspection, and it is possible to switch pages of NG images by moving the bar left and right. B806 is an inspection end button, and the user can end the print inspection by operating it after checking the print inspection.

[0083] B807 is a scroll bar for switching the detailed information of the first to third abnormalities. The display of the detailed information of the first to third abnormalities can be switched by moving the bar up and down. As shown in the inspection result screen 8000, when the scroll bar B807 is at the top, detailed information of the first and second abnormalities is displayed. That is, here, when the number of normal enlarged images and abnormal enlarged images of the detected abnormal parts exceeds the upper limit that can be displayed, enlarged images of some of the abnormal parts are displayed, and enlarged images of other abnormal parts are not displayed. On the other hand, the inspection result screen 8100 shows the state when the scroll bar B807 is at the bottom.

[0084] In the inspection result screen 8100, the detailed information area scrolls down, and the detailed information of the first abnormality is hidden, and instead, the detailed information of the third abnormality is displayed. B804b shows the normal character string at the position of B804a, and B804c shows an enlarged image of the abnormality at the position of B804a. B804d shows the character recognition (decode) result of the character inspection area. In this way, for the third abnormality, which is an abnormality in the character inspection, in addition to the simultaneous display of the normal character string and the enlarged image of the abnormality, the character recognition (decode) result of the character inspection area is also displayed.

[0085] Thus, according to this embodiment, detailed information for each abnormality can be switched and displayed by moving the scroll bar B807 up and down. Therefore, even if the number of abnormalities exceeds the number that can be displayed simultaneously, detailed information for all abnormalities can be displayed in sequence. Even in a job with many abnormalities, the user can shorten the time from when the print inspection is NG to when the acceptance judgment and the inspection level are optimized, thereby reducing downtime of the device. As a result, usability can be improved when the user judges the level of abnormality in the print.
