20230011106
The present invention relates to an information processing apparatus, an information processing method, an inspection system and a storage medium.
An image inspection apparatus which reads a printed matter printed by a printer and inspects the quality of the printed matter is known. The image inspection apparatus can detect image defects such as dirt and print omission, errors in characters, bar code quality, and the like. For example, Japanese Patent Application Laid-Open No. 2021-078083 discloses an example of the image inspection apparatus.
If the image inspection apparatus and the printer are independently operable on one side, including a power source, the one apparatus may be able to execute the processing without depending on a state of the other apparatus. Under such conditions, for example, when the operation of the image inspection apparatus is restricted, it can be assumed that a printed matter corresponding to a print result by the printer is not inspected even though the inspection is scheduled, and as a result, the printed matter is treated as defective. Consequently, there is a need to realize a mechanism capable of linking the image inspection apparatus and the printer, which can operate independently, in a more suitable manner.
In view of the above problems, it is an object of the present invention to link the image inspection apparatus and the printer in a more suitable manner.
In an aspect of the present disclosure, an information processing apparatus comprises at least one processor and at least a memory coupled to the at least one processor and having instructions stored thereon, and when executed by the at least one processor, acting as: a determination unit configured to determine whether or not an image inspection apparatus is operable to execute an inspection of the presence of defects in a captured image capturing a surface to be inspected of a printed matter; and a controller configured to control the execution of processes associated with printing based on a result of the determination by the determination unit.
Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Embodiments of the present invention will now be described with reference to the drawings. In the present specification and the drawings, components having substantially the same functional configuration are denoted by the same reference numerals, thereby omitting the redundant description.
Unless otherwise stated, it is needless to say that the present invention can be applied to a single apparatus or to an inspection apparatus comprising a plurality of apparatuses, provided that the functions of the present invention are realized. Unless otherwise stated, it is needless to say that the present invention can be applied to an inspection apparatus which is connected via a network such as a LAN (Local Area Network) or WAN (Wide Area Network) and performs processing, provided that the functions of the present invention are realized. That is, the system configuration in which various terminals described in the following embodiments are connected is only one example, and it goes without saying that there are various configuration examples depending on the use and purpose.

<Internal Configuration>
Referring to
The printer 101 receives a user's input via the UI panel 102 and displays states of printing and equipment on the UI panel 102. Various types of paper can be stored in the paper feed decks 103 and 104. In each paper feed deck, one sheet of the uppermost sheet of the stored sheets can be separated and conveyed to a sheet conveying path 305.
The developing stations 301 to 304 form a toner image using colored toners of Y (yellow), M (magenta), C (cyan), and K (black), respectively, to form a color image. The toner image formed here is primarily transferred to an intermediate transfer belt 306. The intermediate transfer belt 306 rotates clockwise in the figure and transfers the toner image to a sheet conveyed from the sheet conveying path 305 at a secondary transfer position 307.
A fixing unit 308 is provided with a pressure roller and a heating roller, and the toner image is fixed to the sheet by melting and pressure-bonding the toner by passing the sheet between the rollers. The sheet having passed through the fixing unit 308 is conveyed to a sheet conveying path 309 to a sheet conveying path 312. If further melting/crimping is required for fixing, depending on the type of paper, the sheet is conveyed to a second fixing unit 310 through the above sheet conveying path after passing through the fixing unit 308, and is conveyed to the sheet conveying path 312 through a sheet conveying path 311 after additional melting/crimping is performed.
If the image forming mode is double-sided, the sheet is conveyed to a sheet reversing path 313. After the paper is reversed at the sheet reversing path 313, the paper is conveyed to a double-sided conveying path 314, and the image of the second side is transferred at the secondary transfer position 307.
A CIS 315 and a CIS 316 are arranged in the inspection unit 106 to face each other.
The CIS 315 is a sensor for reading the upper surface of the sheet. The CIS 316 is a sensor for reading the lower surface of the sheet. The inspection unit 106 scans (captures) the sheet using the CIS 315 and the CIS 316 at the timing when the paper conveyed to a paper conveying path 317 reaches a predetermined position. The scanned image (captured image) is transmitted to the inspection apparatus 108 via the inspection apparatus I/F 215 and the inspection unit I/F 231. The CPU 226 determines whether or not the received image has a defect, and notifies the result of the determination to the inspection unit 106 again via the inspection unit I/F 231 and the inspection apparatus I/F 215. The CPU 216 notifies the large-capacity stacker 107 of the received determination result via the accessory interfaces 214 and 220.
The symbol 107 denotes a large-capacity stacker capable of stacking a large number of sheets. The large-capacity stacker 107 has a main tray 324 as a tray for stacking sheets. The sheet having passed through the inspection unit 106 enters the large-capacity stacker 107 through the sheet conveying path 319. The sheets are stacked on the main tray 324 from the sheet conveying path 319 via a sheet conveying path 322.
The large-capacity stacker 107 has a top tray 320 as a paper discharge tray. The CPU 221 ejects the sheet in which a defect is detected by the inspection apparatus 108 to the top tray 320. When the sheet is output to the top tray 320, the sheet is conveyed from the sheet conveying path 319 to the top tray 320 via the paper conveying path 321. The symbol 323 denotes a reversing unit for reversing a sheet. The reversing unit 323 is used for stacking sheets in the main tray 324. If the sheets are stacked in the main tray 324, the sheets are once reversed by the reversing unit 323 so that the direction of the sheets entering the large-capacity stacker 107 becomes same as the direction of the sheets stacked. The reversing operation by the reversing unit 323 is not performed when the sheets are conveyed to the top tray 320, because the stacked sheets are discharged as it is without flipping.
<Processing>
The processing of the inspection system according to the present embodiment will be described with reference to
First, with reference to
In step S401, the CPU 226 receives an instruction to start reading an image from the user via the display unit 245.
In step S402, the inspection unit I/F 231 notifies the inspection unit 106 through the inspection apparatus I/F 215 that the inspection apparatus 108 is operable to read the image.
In step S403, the inspection unit I/F 231 determines, based on a notification from the inspection apparatus I/F 215, whether or not it is detected that the sheet (printed matter) to be inspected has been conveyed to the inspection unit 106.
If the inspection unit I/F determines that the sheet to be inspected has not been detected to be conveyed to the inspection unit 106, the inspection unit I/F 231 continues to wait for notification from the inspection apparatus I/F 215 in step S403.
If the inspection unit I/F 231 determines that the sheet to be inspected has been conveyed to the inspection unit 106, the process proceeds to step S404.
In step S404, the inspection unit I/F 231 receives from the inspection apparatus I/F 215 an image (hereinafter also referred to as “scanned image”) corresponding to the scan results (in other words, the capturing result) by the CIS 315 and the CIS 316.
In step S405, the CPU 226 compares the reference image stored in the RAM 227 with the scan image to be inspected received in step S405. As for the reference image, for example, a scan image obtained by scanning a printed matter corresponding to a print result by the printer 101 using the CIS 315 and the CIS 316 before starting the series of processes shown in
An example of a process for comparing a reference image with a scan image will now be described. In the process relating to the comparison, first, characteristic points extracted from each of the reference image and the scan image to be inspected are used as reference points for alignment, so that the image positions of the reference image and the scan image are aligned. Next, with respect to the scan image to be inspected, the presence of positional deviation of the image with respect to the sheet is inspected by analyzing the four corners of the sheet along with the reference points for alignment of the scan image. Then, density values of the reference image and the scan image to be inspected are compared for each pixel. As a result, if no defect is detected, the inspection result is recognized as “passed”.
The inspection method of the scan image based on the comparison between the reference image and the scan image described above is only an example, and if it is possible to inspect the scan image by detecting a defect from the scan image of the printed matter, the inspection method is not particularly limited. As a specific example, an image analysis may be performed on a scan image of a printed matter, and the scan image may be inspected by determining whether or not a feature corresponding to a defect has been detected based on the result of the image analysis.
In step S406, the CPU 226 determines whether or not the inspection result shows “passed” based on the comparison result in step S405.
If the CPU 226 determines that the inspection result shows “passed” in step S406, the CPU advances the process to step S407. In step S407, the inspection unit I/F 231 notifies the inspection apparatus I/F 215 that the inspection result shows “passed”, so as to instruct paper discharge of the target printed matter to the main tray 324 of the large-capacity stacker 107.
If it is determined that the inspection result shows “failed” in step S406, the CPU 226 advances the process to step S408. In step S408, the inspection unit I/F 231 notifies the inspection apparatus I/F 215 that the inspection result shows “failed”, and instructs to discharge the target printed matter to the top tray 320 of the large-capacity stacker 107.
In step S409, the CPU 226 determines whether or not the inspection of the last sheet has been completed.
If it is determined in S409 that the inspection of the last sheet has not been completed, the CPU 226 advances the process to S403. In this case, the processes of steps S403 to S409 are executed again for the sheet whose inspection has not been completed.
If the CPU 226 determines that the inspection of the last sheet is completed in step S409, the CPU advances the process to step S410. In step S410, the CPU 226 receives an instruction related to the end of reading the image from the user via the display unit 245.
In step S411, the inspection unit I/F 231 notifies the inspection unit 106 through the inspection apparatus I/F 215 that the inspection apparatus 108 is in a state in which reading of an image is impossible, and ends the series of processes shown in
Next, with reference to
In step S501, the printer 101 receives a print job under control of the CPU 201.
In step S502, the CPU 201 starts the printing process based on the print job received in step S501.
In step S503, the CPU 201 executes processing related to printing an image on a sheet (single sheet).
In step S504, the inspection apparatus I/F 215 notifies the inspection apparatus 108 via the inspection unit I/F 231 that the sheet (printed matter) to be inspected has been conveyed to the inspection unit 106.
In step S505, each of the CIS 315 and the CIS 316 scans an image printed on the conveyed sheet.
In step S506, the inspection apparatus I/F 215 transmits the image scanned in step S505 to the inspection unit I/F 231.
In step S507, the CPU 216 determines whether or not the inspection result of the image received by the inspection apparatus I/F 215 from the inspection unit I/F 231 and transmitted to the inspection unit I/F 231 in step S506 shows “failed”.
If the CPU 216 determines that the inspection result shows “failed” in S507, the CPU advances the process to step S508. In step S508, the CPU 216 instructs each of the accessory interfaces 208, 214, and 220 to discharge the sheets (printed matters) determined as “failed” in the inspection result to the top tray 320.
If it is determined that the inspection result does not show “failed” in step S507, the CPU 216 advances the process to step S509. In step S509, the CPU 216 instructs each of the accessory interfaces 214 and 220 to discharge the sheets to be inspected to the destination specified by the print job.
In step S510, the CPU 201 determines whether or not the inspection of the last sheet has been completed.
If it is determined in step S510 that the inspection of the last sheet has not been completed, the CPU 201 advances the process to step S503. In this case, the processes of steps S503 to S509 are executed again for the sheets for which the inspection has not been completed.
If the CPU determines that the inspection of the last sheet has been completed in step S510, the CPU 201 terminates the series of processes shown in
Next, with reference to
First, with reference to
In step S601, the CPU 201 accepts a print job.
In step S602, the CPU 201 sets the inspection unit 106 so that the inspection apparatus I/F 215 notifies the inspection unit I/F 231 of each conveyance of the sheet to be inspected.
In step S603, the CPU 201 analyzes the job received in step S601.
In step S604, the CPU 201 compares the analysis result of the job in step S603 with the management table shown in
If the CPU 201 determines in step S604 that the received job corresponds to a job type that requires no inspection, the CPU advances the process to step S605. In step S605, the CPU 201 acquires from the inspection unit 106 information (for example, information indicating whether or not the image can be read) about the state of reading the image of the inspection apparatus 108.
In step S606, the CPU 201 determines, based on the information acquired in step S605, whether or not the inspection apparatus 108 is operable to read the image.
If it is determined in step S606 that the inspection apparatus 108 is unable to read the image, the CPU 201 advances the process to step S607. In step S607, the CPU 201 executes a process related to printing based on the print job received in step S601.
If the CPU determines in step S606 that the inspection apparatus 108 is operable to read the image, the CPU 201 advances the process to step S608. In step S608, the CPU 201 updates the setting so that the notification from the inspection apparatus I/F 215 to the inspection unit I/F 231 for each conveyance of the sheet to be inspected to the inspection unit 106 is stopped. As a result, the provision of the captured image (i.e., the image to be inspected) corresponding to the capturing result of the surface to be inspected of the printed matter from the inspection unit 106 to the inspection apparatus 108 is restricted.
Then, in step S609, the CPU 201 executes processing related to printing based on the job received in step S601.
Then, in S610, the CPU 201 updates the setting again so that the notification from the inspection apparatus I/F 215 to the inspection unit I/F 231 for each conveyance of the sheet to be inspected to the inspection unit 106 is resumed. As a result, in the subsequent processing, the restriction on the provision of the captured image from the inspection unit 106 to the inspection apparatus 108 corresponding to the capturing result of the surface to be inspected of the printed matter by the inspection unit 106 is lifted.
If the CPU determines in step S604 that the received job does not correspond to a job type requiring the inspection, the CPU 201 advances the process to step S611. In step S611, the CPU 201 acquires from the inspection unit 106 information about the state of the inspection apparatus 108 that performs reading of the image.
In step S612, the CPU 201 determines, based on the information acquired in step S605, whether or not the inspection apparatus 108 is operable to read the image.
If it is determined in step S612 that the inspection apparatus 108 is operable to read the image, the CPU 201 advances the process to step S607. In step S607, the CPU 201 executes processing related to printing based on the job received in step S601.
If the CPU determines in step S612 that the inspection apparatus 108 is unable to read the image, the CPU 201 advances the process to step S613. In step S613, the CPU 201 causes the UI panel 203 to display a screen (not shown) for receiving permission for printing a job from a user. The CPU 201 receives permission for printing a job from the user through the screen.
In step S614, the CPU 201 determines whether or not permission for printing the job has been received from the user via the screen displayed on the UI panel 203 in step S613.
If the CPU 201 determines that the permission for printing the job has been received from the user in step S614, the CPU advances the process to step S607. In step S607, the CPU 201 executes processing related to printing based on the job received in step S601.
If it is determined in step S614 that the permission for printing the job has not been received from the user, the CPU 201 advances the process to step S615. In step S615, the CPU 201 cancels the job received in step S601. Thus, the execution of processing related to printing based on the job is restricted.
Next, a modified example of the inspection system according to the present embodiment will be described with reference to

The symbol 803 denotes an end button for receiving from the user an instruction for ending registration of job types requiring no inspection. If the end button 803 is pressed, the process related to the registration of the job types requiring no inspection is finished, and the display of the registration screen 801 is closed.
Next, with reference to
In step S901, the CPU 201 causes the UI panel 102 to display the registration screen 801.
In step S902, the CPU 201 determines whether or not an instruction for terminating the registration of job types requiring no inspection has been received (that is, whether or not the end button 803 has been pressed).
If the CPU 201 determines that the instruction for terminating the registration of the job types requiring no inspection has been received in step S902, the CPU 201 terminates the series of processes shown in
If the CPU 201 determines that the instruction for terminating the registration of job types requiring no inspection is not received in step S902, the CPU 201 advances the process to step S903.
In step S903, the CPU 201 determines whether or not an instruction for registering job types requiring no inspection has been received (that is, whether or not the setting button 802 has been pressed).
If the CPU 201 determines in step S903 that an instruction related to the registration of job types requiring no inspection has not been received, the CPU 201 advances the process to step S902. In this case, the process is executed again from step S902.
If the CPU 201 determines that an instruction related to the registration of job types requiring no inspection has been received in step S903, the CPU 201 advances the process to step S904. In step S904, the CPU 201 registers a job type selected via the check boxes 804 to 806 in the management table shown in
Upon completion of the process relating to the registration of job types requiring no inspection, which is indicated as step S904, the CPU 201 terminates the series of processes shown in
Next, with reference to
In step S1101, the CPU 201 receives a print job.
In step S1102, the CPU 201 sets the inspection unit 106 to let the inspection apparatus I/F 215 notify the inspection unit I/F 231 of each conveyance of the sheet to be inspected.
In step S1103, the CPU 201 analyzes the job received in step S1101.
In step S1104, the CPU 201 compares the analysis result of the job in step S1103 with the management table shown in
If the CPU 201 determines in step S1104 that the received job corresponds to a job type requiring no inspection, the CPU 201 advances the process to step S1105. In step S1105, the CPU 201 acquires from the inspection unit 106 information about a state of reading the image of the inspection apparatus 108 (for example, information indicating whether or not the image can be read).
In step S1106, the CPU 201 determines, based on the information acquired in step S1105, whether or not the inspection apparatus 108 is operable to read the image.
If it is determined in step S1106 that the inspection apparatus 108 is not operable to read the image, the CPU 201 advances the process to step S1107. In step S1107, the CPU 201 executes a process related to printing based on the print job received in step S601.
If the CPU determines in step S1106 that the inspection apparatus 108 is operable to read the image, the CPU 201 advances the process to step S1108. In step S1108, the CPU 201 updates the setting to stop sending to the inspection unit 106 the notification from the inspection apparatus I/F 215 to the inspection unit I/F 231 for each conveyance of the sheet to be inspected. Thereby, the provision of a captured image (i.e., an image to be inspected) in accordance with a result of the captured surface to be inspected of the printed matter by the inspection unit 106 from the inspection unit 106 to the inspection apparatus 108 is restricted.
Then, in step S1109, the CPU 201 executes processing related to printing based on the job received in step S1101.
Then, in step S1110, the CPU 201 updates the setting again for the inspection unit 106 to resume the notification from the inspection apparatus I/F 215 to the inspection unit I/F 231 for each conveyance of the sheet to be inspected. As a result, in the subsequent processing, the restriction on the provision of the captured image from the inspection unit 106 to the inspection apparatus 108 in accordance with a result of the captured surface to be inspected of the printed matter by the inspection unit 106 is removed.
If the CPU 201 determines in step S1104 that the received job do not correspond to a job type requiring inspection, the CPU 201 advances the process to step S1111. In step S1111, the CPU 201 refers to the user registration management table shown in
In step S1112, the CPU 201 determines whether or not the job received in step S1101 is registered as a job type requiring no inspection.
If the CPU 201 determines in step S1112 that the job type of the target job is registered as a job type not requiring inspection, the CPU 201 advances the process to step S1105. The processes after step S1105 are same as the process after step S605 described in
If the CPU 201 determines that the target job is not registered as a job type requiring no inspection in step S1112, the CPU advances the process to step S1113. In step S1113, the CPU 201 acquires from the inspection unit 106 information about a state of reading the image of the inspection apparatus 108.
In step S1114, the CPU 201 determines, based on the information acquired in step S1113, whether or not the inspection apparatus 108 is operable to read the image.
If it is determined in step S1114 that the inspection apparatus 108 is operable to read the image, the CPU 201 advances the process to step S1107. In step S1107, the CPU 201 executes processing related to printing based on the job received in step S1101.
If the CPU determines in step S1114 that the inspection apparatus 108 is not operable to read the image, the CPU 201 advances the process to step S1115. In step S1115, the CPU 201 causes the UI panel 203 to display a screen (not shown) for receiving permission for printing the job from the user. The CPU 201 receives permission for printing the job from the user through the screen.
In step S1116, the CPU 201 determines whether or not permission for printing the job has been received from the user via the screen displayed on the UI panel 203 in step S1115.
If the CPU 201 determines that the permission for printing the job has been received from the user in step S1116, the CPU advances the process to step S1107. In step S1107, the CPU 201 executes processing related to printing based on the job received in step S1101.
If it is determined in step S1116 that the permission for printing the job has not been received from the user, the CPU 201 advances the process to step S1117. In step S1117, the CPU 201 cancels the job received in step S1101. Thus, the execution of processing related to printing based on the job is restricted.
In the present modification, a job type of a job requiring no inspection based on an instruction from the user is subject to registration, but the operation of the inspection system according to the present modification is not necessarily limited to the above configuration. That is, the information to be registered is not limited to the job type as long as it is possible to specify the job for which no inspection is required. As a specific example, it is also possible to control the operations of the inspection system such that information about jobs other than job types like names of specific jobs are to be registered, and a job holding specific information is considered as requiring no inspection.
Embodiment(s) of the present invention can also be realized by a computer of a system or apparatus that reads out and executes computer executable instructions (e.g., one or more programs) recorded on a storage medium (which may also be referred to more fully as a ‘non-transitory computer-readable storage medium’) to perform the functions of one or more of the above-described embodiment(s) and/or that includes one or more circuits (e.g., application specific integrated circuit (ASIC)) for performing the functions of one or more of the above-described embodiment(s), and by a method performed by the computer of the system or apparatus by, for example, reading out and executing the computer executable instructions from the storage medium to perform the functions of one or more of the above-described embodiment(s) and/or controlling the one or more circuits to perform the functions of one or more of the above-described embodiment(s). The computer may comprise one or more processors (e.g., central processing unit (CPU), micro processing unit (MPU)) and may include a network of separate computers or separate processors to read out and execute the computer executable instructions. The computer executable instructions may be provided to the computer, for example, from a network or the storage medium. The storage medium may include, for example, one or more of a hard disk, a random-access memory (RAM), a read only memory (ROM), a storage of distributed computing systems, an optical disk (such as a compact disc (CD), digital versatile disc (DVD), or Blu-ray Disc (BD)™), a flash memory device, a memory card, and the like.
Further, the system configuration described with reference to
As a specific example, an information processing apparatus for controlling the operation of the printer 101 and the inspection unit 106 may be separately provided. In this case, the information processing apparatus may control the execution of the printing process by the printer 101 in accordance with the capability of the inspection apparatus 108 for reading an image (in other words, whether the inspection is feasible or not). In addition, the information processing apparatus may restrict the provision of a captured image from the inspection unit 106 to the inspection apparatus 108 in accordance with a captured result of the surface to be inspected of the printed matter by the inspection unit 106, depending on whether a target print job requires inspection or not.
According to the embodiment described above, it is possible to link the image inspection apparatus and the printer in a more suitable manner.
