Description

  The present invention relates to an image correction process in an image processing apparatus.

  In the printing market, high productivity that keeps producing printed matter without slowing down the printing speed of image processing equipment, high image quality that can print image quality with high quality, and stability that can continue to operate stably for a long time are very high Is an important performance factor. In order to realize high productivity, the fixing device generally has a configuration capable of holding a large amount of heat so as to increase the printing speed and perform a fixing operation corresponding to the printing speed. Therefore, in order to store the amount of heat necessary for image formation in the fixing device immediately after the power is turned on and perform the fixing process stabilization processing, it is common to provide a wait time for which image formation is not performed for a certain period of time. In order to achieve high image quality, various image correction processes are generally performed. Some of the triggers for executing the image correction are based on an execution instruction from the user, and some are automatically performed when the image processing apparatus satisfies a predetermined condition without requiring an instruction from the user.

  When the user issues an instruction to execute the image correction process, a button for instructing the start of the image correction mode is provided on the operation panel of the image processing apparatus, and this button is pressed when the user determines that the correction process needs to be executed. Press. In general, an image processing apparatus is instructed to perform image correction processing.

  In addition, when the image correction process is automatically executed, for example, immediately after the power is turned on, when it is determined that the actual values of the environmental temperature, the environmental humidity, and the number of printed sheets satisfy predetermined conditions, the image correction process is automatically performed. Correction is performed.

  In order to realize image stability, many image processing apparatuses as described above automatically determine whether or not to perform image correction processing. If the number of continuous prints exceeds a predetermined number while the print operation is continued, the print operation may be interrupted and image correction processing may be performed, or the image correction may be performed at the end of the job. There are also things. This is a process for avoiding a change in color by performing image correction in the middle of one print job.

  Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for shortening the time required for image correction that is performed when the wait time of the image processing apparatus ends and image formation becomes possible.

  Japanese Patent Application Laid-Open No. 2005-228561 discloses a technique that enables setting in advance so that image correction is executed at a timing desired by a user.

JP2009-300525 JP 2000-305327 A

  Since it takes time to store heat in the fixing device described above, in an image processing apparatus provided with a wait time that does not execute image formation immediately after power-on or immediately after returning from sleep, the user cannot operate the image processing apparatus during the wait time. There is a case where it waits until the end of the wait time.

  In this case, an ordinary print job can be reserved even during a wait. However, the image correction by the user operation as described above may be configured not to give an instruction to start the correction until the image processing apparatus is ready for printing. Therefore, even if the above prior art is used, execution of image correction cannot be set at a timing desired by the user during the wait time.

  There are various types of image correction. For example, a test pattern image for correction processing is printed on a sheet, and the user installs the test pattern image on the image reading apparatus. In some cases, the image output from the image processing apparatus is corrected by reflecting the result of reading the test pattern image by the image reading apparatus on the image parameter.

  As described above, when executing an image correction process that requires a user operation for reading the test pattern image, the test pattern image is printed during the wait time even if the execution of the image correction process is reserved during the wait time. The user cannot perform the reading operation. Therefore, the user needs to wait until the test pattern image is printed on the paper. That is, even if it is possible to make an execution reservation for image correction processing during the wait time, the user cannot leave the image processing apparatus until the wait time ends. For this reason, it is difficult for the user to give an instruction to execute the image correction process.

In order to solve the above problems, an image processing apparatus of the present invention reproduces an image formed by an image forming unit that forms an image and an image formed by the image forming unit based on a result of measuring an image formed by the image forming unit. Correction data generating means for generating correction data for correcting the characteristics, and the result of measuring the image is a value measured by a sensor installed in the paper conveyance path or acquired from a connected reading device A determination unit that determines whether the value is a value; and if the result of measuring the image by the determination unit is determined to be a value measured by a sensor installed in the paper conveyance path, wherein receiving an instruction to execute a correction data generating process executed by the correction data generating means after fixing process stabilization process ends, the image was measured by the determining means When it is determined that the result is a value acquired from the connected reading device, the correction data generation process executed by the correction data generation unit after the fixing process stabilization process ends before the fixing process stabilization process ends and having a control means for controlling so as not to receive an indication of.

  According to the present invention, even if the execution of the image correction process is instructed at the timing intended by the user during the wait, it is possible to improve the hand of the user instructing the image correction process.

[Example 1]
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1, FIG. 8, and FIG. 9 mainly show the features of this embodiment. FIG. 1 is an example of an operation unit screen for instructing image correction by a user operation. FIG. 1B shows a top screen that is displayed first when image correction is performed. A button 104 is used to select a paper type, and is used when the paper type is selected by the user. Buttons 105 and 106 are buttons for selecting the type of correction. The button 105 is a button for instructing execution of full correction. When full correction is performed, a test pattern image is printed on a sheet, and the printed test pattern image is read and read by a sensor. The read data is fed back to the image correction parameters to correct the reproduction characteristics of the image output from the image processing apparatus.

  The sensor used when reading the test pattern image switches between reading by the scanner unit 202 (to be described later) and reading by the reading sensor 365 in the printer unit 203 via a screen displayed after the method selection button 109 is pressed. Can do. When the scanner unit 202 reads the image, it is necessary for the user to perform an operation of loading the test pattern image output from the printer unit 203 on the scanner unit 202 as a read original.

  On the other hand, when the sensor pattern 365 in the printer unit reads the test pattern image, the sensor 365 installed between the fixing device on the paper transport path in the printer unit and the paper discharge port performs a reading process on the paper transport path after fixing. Is called. Therefore, the user can complete the operation with only one operation for giving an execution instruction at the start of the correction process. That is, the user does not need to perform a reading operation.

  Reference numeral 107 denotes a button for registering correction paper. Reference numeral 108 denotes a button for selecting a correction sheet. Reference numeral 110 denotes a button for setting the number of sheets used for outputting the test pattern image. Reference numeral 111 denotes a button that can further correct the correction level. Reference numeral 112 denotes a process for performing initialization when full correction is performed. Reference numeral 113 denotes an OK button for closing this screen when the image correction operation is completed.

  In the conventional case, when the printer is being prepared, when the user selects the button 105 for instructing the execution of full correction, no matter which setting is specified by the method selection 109, the setting shown in FIG. ) Screen 101. On the screen 101 in FIG. 1A, the button 102 for starting image correction is grayed out as shown in the figure and is controlled not to be pressed by the user.

  Therefore, until the printer preparation is canceled, the user has to press the cancel button 103 to end the process or wait for the printer preparation to be canceled.

  In the present embodiment, the display method of the button for instructing the start of image correction is switched as follows according to the method selection 109.

  That is, as shown in FIG. 1C, the button 114 for instructing the start of image correction is displayed in gray so that the button cannot be operated during printer preparation. Alternatively, as shown in FIG. 1D, the button 115 for instructing the start of image correction is not grayed out, the button can be operated even during printer preparation, and the screen is controlled so that the user can start image correction. When a test pattern image is read by the scanner unit 202 by the method selection 109, a button 114 indicating the start of image correction is displayed on the screen.

  On the other hand, when the test pattern image is read by the sensor 365 in the printer unit by the method selection 109, a button 115 indicating the start of image correction is displayed on the screen.

  The reason for such control will be described later with reference to FIG.

  FIG. 8 is a timing chart illustrating what timing is processed when image correction is reserved after the screen control of the operation unit in FIG. 1 is performed.

  First, the image processing apparatus according to this embodiment will be described with reference to FIGS.

  FIG. 2A shows an image processing apparatus to which a main controller 201 that mainly controls job scheduling, a scanner unit 202 that is an image reading device that reads a paper document, and a printer unit 203 that prints an image is connected. Indicates. A detailed connection form of the main controller 201, the scanner unit 202, and the printer unit 203 will be described with reference to FIG. The printer unit 203 will be described in detail with reference to the mechanical cross-sectional view of FIG.

  Further, the main controller 201 is connected to the PC 205 via the network 206. A job can be submitted from the PC 205 to the main controller 201 using a printer driver or the like. FIG. 2B is a control block diagram inside the main controller 201. The operation screen control unit 210 controls the operation screen of FIG. The job execution order control unit 211 controls the execution order of various jobs such as a normal print job, an image correction job by a user operation, and an image correction job by an image correction request due to a printer factor.

  The job described here is a series of processes to be executed. For example, in the case of a copy function, a series of processing from when a user sets a document and presses a copy start button until printing is completed is called a job. In the case of a print function, a series of processing from when a print instruction is issued from a PC until a document is printed is called a job.

  Therefore, the image correction job refers to a series of processes for completing the correction process.

  The image correction determination unit 212 determines whether image correction is necessary. The image correction determination unit 212 determines whether the image correction execution request is made by a user instruction via the operation screen control unit 210 or a printer factor notified from the printer status monitoring unit 214.

  The image correction execution request due to the printer is when the apparatus satisfies a preset condition, for example, when the printer status monitoring unit 214 determines that the actual value of the environmental temperature / humidity and the number of printed sheets at the time of power-on is satisfied. It is what is required.

  In this case, the printer status monitoring unit 214 notifies the image correction execution request so that the image correction is automatically executed without receiving an execution instruction from the user.

  Note that the image correction processing executed due to printer factors does not require any user action. Image correction processing that does not require user action will be described later.

  When the image correction determination unit 212 receives an image correction execution request and determines that image correction is necessary, the image correction determination unit 212 performs control to input a job to the job execution order control unit 211.

  The image correction execution unit 213 executes image correction in response to a request for execution instruction of an image correction job transmitted from the job execution order control unit 211 when the job execution order control unit 211 determines the execution order of the image correction job. .

  The above is the description of the control block diagram in the main controller.

  Next, FIG. 3 is an overall mechanical cross-sectional view including the image processing apparatus, the sheet feeding apparatus, and the post-processing apparatus. Broadly speaking, 301 is an image processing apparatus main body, and 302 is an image fixing apparatus. 301 and 302 are combined to form an image on a sheet. A large-capacity paper feed deck 320 is connected to the image processing apparatus main body 301 and operates as a paper feed device. A plurality of paper feed decks 320 can be connected, and a large capacity paper feed deck 321 is further connected. In the post-processing device, a large-capacity stacker (hereinafter referred to as a stacker a) 346 is connected to the image fixing device 302. A plurality of large capacity stackers 346 can be connected, and a large capacity stacker (hereinafter referred to as a stacker b) 347 is connected. Furthermore, a finisher 334 is connected.

  The image processing apparatus 301 includes sheet feeding decks 305 and 306 and operates as a standard sheet feeding unit. The developing units 307 to 310 are composed of four stations of Y, M, C, and K for forming a color image. The image formed here is primarily transferred to the intermediate transfer belt 311. The intermediate transfer belt rotates clockwise in the figure, and the image is transferred to the sheet conveyed from the sheet conveyance path 304 at the secondary transfer position 312. The The image transferred onto the sheet is transferred from the image processing apparatus main body 301 to the image fixing apparatus 302, and is fixed on the sheet by being heated and pressurized by the fixing device 313 in the image fixing apparatus 302.

  The paper that has passed through the fixing device 313 passes through the transport path 315 and is transported to 317. If additional heating and pressurization are required for fixing depending on the type of paper, the paper passes through the fixing device 313 and is then transported to the second fixing device 314 using the upper transport path. Here, after additional heating and pressurization, the sheet is conveyed to 317 through a conveyance path 316. When the image forming mode is duplex, the sheet is conveyed to the sheet reversing path 318, reversed at 318, then conveyed to the duplex conveying path 319, and re-feeded. Image formation on the second side is performed again.

  An image correction reading sensor 365 exists in the paper path for carrying the paper on both sides or performing a reversing operation. This sensor 365 is a sensor for reading a test pattern printed on a sheet when full correction is performed without using the scanner unit 202 (reader 364).

  This sensor 365 may be provided between the fixing device in the paper transport path and the paper discharge port.

  In addition to the standard paper feed unit of the image processing apparatus, it is also possible to feed paper from the paper feed decks 322, 323, and 324 of the large capacity paper feed deck 320. The fed paper is transported to the paper transport paths 325 and 326 and sent to the image processing apparatus main body 301 for image formation. When the second large-capacity paper feed deck is connected, it is possible to feed paper also from the paper feed decks 329, 330, and 331. Delivered to the second large-capacity paper feed deck. These large-capacity paper feed decks have a function of detecting a multi-feed transported in a state where a plurality of sheets are overlapped. When a multi-feed is detected, the paper transport path is changed from the normal 326. Switch to 327 and discharge the paper to the escape tray 328.

  Next, the large capacity stacker 346 of the post-processing apparatus will be described. The large-capacity stacker has two output destinations, ie, a stack unit composed of a discharge tray 350, a lift table 348, and an eject table 349 as output trays for paper. The paper on which image formation has been completed is input from the image fixing device 302 to the paper transport unit of the large-capacity stacker through 317. The sheets are stacked on the lift table 348 of the stack unit via the sheet conveyance paths 351 to 352. When the sheet bundle is not stacked, the lift table 348 is at the upper position shown in the figure. When the stacking of the sheet bundle proceeds, the lift table 348 is lowered by the height of the sheet bundle, and the upper end position of the stacked sheet bundle is always controlled to be a constant height. When the stacking of the sheet bundle is completed or the stack is full, the lift table 348 is lowered to the position of the eject table 349. The lift table 348 and the eject table 349 are configured such that bars exist at alternate positions even when the height is the same. Therefore, when the lift table 348 descends and reaches a position lower than the eject table 349, the sheet bundle is in a state where the eject table 349 is reloaded. When outputting to the paper discharge tray 350, the paper is conveyed to the paper discharge tray 350 via the paper conveyance paths 351 to 353. Further, when the sheet is transported to the post-processing apparatus at the subsequent stage of the large-capacity stacker 346, the sheet is transported via the sheet transport path 354 and transported to the second large-capacity stacker 347 or the finisher 334. The reversing unit 355 has a mechanism for reversing the paper. The reversing unit 355 is basically controlled so that the orientation of the sheet input to the large-capacity stacker 346 is the same as the orientation of the sheet at the output destination.

  That is, when stacked on the stack unit, the paper that has passed through 352 is flipped and stacked on the lift table 348. Therefore, if the paper is not reversed by the reversing unit 355, the paper is fed by 317 and 348. Upside down. Therefore, when stacking on the stack unit, the sheet is reversed once by the reversing unit 355 so that the sheet is vertically aligned at 317 and 348. When transported to the paper discharge tray 350 or the subsequent post-processing apparatus, the paper is discharged as it is at the time of stacking, so that the same paper as in 317 is turned up and down. Therefore, the reversing unit 355 does not perform the reversing operation. Further, the tip of the reversing unit 355 is an escape unit, and a sheet that can be conveyed when an abnormal operation such as a jam or an error occurs can be conveyed to the escape unit. Therefore, it is controlled so that the paper staying on the paper feeding unit side from the reversing unit 355 in the transporting path can be transported and is stacked on the escape unit at the end of the reversing unit 355.

  The second large-capacity stacker 347 has the same configuration as the above-described stacker 346, and each mechanism from 356 to 363 is the same as each of the first large-capacity stacker from 348 to 355.

  Next, the finisher 334 will be described. The finisher 334 performs post-processing on the printed paper according to the function designated by the user. Specifically, it has functions such as stapling (1 and 2 binding), punching (2 and 3 holes), and saddle stitch binding. The finisher 334 has paper discharge trays 335 and 336, and is output to 335 via the paper transport path 341. Processing such as stapling cannot be performed on the paper transport path 341. When processing such as stapling is performed, finishing of a function designated by the user is executed by the processing unit 343 via the paper conveyance path 342 and the paper is discharged to the paper discharge tray 336. The paper discharge trays 335 and 336 can be moved up and down, and the paper discharge tray 335 can be moved down so that the sheets finished by the 343 are stacked from the lower paper discharge port. When the insertion sheet is designated by the user, the insertion sheet set in the inserter 338 on a predetermined page can be operated to be inserted through the sheet conveyance path 340. When saddle stitch bookbinding is designated, the saddle stitch processing unit 344 staples the sheet in the center, and then folds the sheet in half and outputs it to the saddle stitch bookbinding tray 337 via the sheet conveyance path 345. The bookbinding tray 337 has a belt conveyor configuration, and the saddle stitch booklet bundle stacked on the bookbinding tray 337 is transported to the paper discharge outlet side.

  The reader 364 and the document feeder (not shown) will be described.

  The reader 364 has the same configuration as the scanner unit 202 shown in FIG.

  These are mainly used in the copy function, but when a document is set on the platen and is read, the document is set on the platen and the document feeder is closed. Then, after the open / close sensor detects that the document table is closed, the reflective document size detection sensor in the scanner casing detects the set document size. The original is irradiated with a light source starting from this size detection, the CCD reads an image and converts it into a digital signal, performs desired image processing, and converts it into a laser recording signal. The converted recording signal is stored in a memory in the controller described later with reference to FIG.

  When a document is set and read in the document feeder, the document is placed face up on the document setting unit of the document feeder. Then, the document presence / absence sensor detects that the document has been set, and the document feed roller and the transport belt rotate in response to this, and the document is transported, and the document is set at a predetermined position on the document table. Thereafter, the image is read in the same manner as reading on the platen and stored in the memory in the controller 201. This scanner is also used for reading a test pattern during full correction using the scanner unit 202 (reader 364) among the image corrections described in this embodiment.

Unlike the full correction, the quick correction outputs a test pattern image on the intermediate transfer belt 311 without outputting it on a sheet. Then, the reproduction characteristics of the image output from the image processing apparatus are corrected using the measurement result of the test pattern measured by the sensor in the image processing apparatus.

  That is, it is not necessary for the user to install the test pattern image output on the paper in the scanner unit 202. Note that the image correction that is automatically executed due to the printer factors described above is quick correction.

  The operation performed by the user to start the quick correction process is a user operation at the time indicated by 701. Hereinafter, the user operation is represented by a black downward triangle.

  When the start of quick correction is instructed by the user operation at the time 701, the test pattern image is output on the intermediate transfer belt 311 during the period 702. Then, the reading operation of the density value of the pattern output to the intermediate transfer belt 311 is performed by a reading sensor (not shown) in FIG. Next, in the period 704, an image lookup is performed to correct the correction value so as to eliminate the difference between the actually measured density value that is read in the period 703 and the density value as the test pattern data that is the ideal density value. Reflect in the table. It is quick correction to perform image correction in this way. If the user operates the apparatus once at the time 701, the execution of the quick correction is completed. Therefore, this is called a “single operation type image correction job”.

  Next, in the processing from 705 to 709 in FIG. 7B, it is selected on the screen shown in FIG. 1B that correction is performed using the sensor 365 in the printer by the method selection 109, and further full correction is performed. 10 shows a time chart of an image correction job to be executed when execution of 105 is selected.

  In this case, a test pattern image is formed on the paper during a period 706 when a full correction execution instruction is given by a user operation at the time 705. One example is 709. When the paper transport direction is the direction of the arrow, a dark and light patch image of the same color is formed in a direction parallel to the arrow, and images are formed in the order of cyan, yellow, magenta, and black in the direction perpendicular to the arrow. Next, this test pattern image is read using a sensor 365 in the printer during a period 707. Sensors 365 in the printer are located between the fixing device in the paper conveyance path of the printer unit 203 and the paper discharge outlet, and are arranged in four rows in the direction perpendicular to the paper conveyance direction. Measurement is performed by one sensor for each color. Do.

  Next, in the period 708, the correction value is reflected in the look-up table so as to correct the difference between the actually measured density value that is the data read in the period 707 and the density value as the test pattern data that is the ideal value. Let

  This image correction is called full correction without using the scanner unit 202 (reader 364).

  Since the test pattern image is read by the sensor 365 installed in the paper conveyance path, the user needs to perform the work of installing the test pattern image output on the paper in the scanner unit 202 in the same manner as the quick correction described above. There is no. Therefore, since the job is executed by one user operation, this correction job is also a single operation type image correction job.

  Next, in the processing from 710 to 721 in FIG. 7C, correction using the scanner unit 202 (reader 364) is selected by the method selection 109 in FIG. 1B, and further execution of full correction 105 is selected. The time chart of the image correction job performed in this case is shown.

  In order to complete all the correction processes, user operations are required at points 710, 711, 712, and 713. When execution of full correction using the scanner unit 202 (reader 364) is instructed by a user operation at the point 710, a test pattern image is printed in a period 714. A specific example of the test pattern image is shown at 720. As the test pattern image, a repeated pattern image having the maximum density of K, C, M, and Y is printed. The sheet on which the pattern image is printed is set on the document table of the scanner unit 202 (reader 364) by the user's work, and the brightness value of the test pattern image is read during the period 715 by the user operation at the time 711. Next, in the period 716, the data read in the period 715 is reflected in the correction process for the maximum density of the image table. Next, the second test pattern image is printed in the period 717 by the user's operation at the time 712. A specific example of the test pattern image printed in the period 717 is shown in 721. As a test pattern image, a pattern image in which halftones of K, Y, M, and C are arranged at predetermined density intervals is printed. This sheet is set again on the document table of the scanner unit (reader 364) by the user's work, and the brightness value of the test pattern image is read in the period 718 by the user operation at the time 713. The read data is reflected in the image lookup table in a period 719.

  This image correction is called full correction using a scanner (reader). In order to obtain a value acquired by using a reading device connected like a scanner (reader), it is necessary to operate and work by a plurality of users before all the correction processes are completed. Therefore, this image correction is called an “interactive image correction job”. This completes the description of the types of image correction jobs.

  Next, details of the reservation control of the image correction job immediately after the power-on that is in the wait state for the image processing apparatus to execute the fixing process stabilization processing will be described with reference to the timing chart of FIG.

  Conventional control is shown at 801 to 810 in FIG. When the power is turned on at the time 801, the image processing apparatus enters a wait time for the period 802. During this period, various kinds of initialization processing and process stabilization processing control for increasing the temperature of the fixing device are performed. As described above, since the high-speed image processing apparatus used in the printing market has a large heat capacity of the fixing device, the period 802 (wait time) required for executing the fixing process stabilization processing is long.

  Therefore, if the control is performed so that the image correction job cannot be reserved during the wait time, the single operation type image correction job shown in FIGS. The interactive image correction job shown in FIG.

  Therefore, in order to instruct the image correction execution, the user is required to wait for the time until the wait time ends (fixing process stabilization processing ends). The operation unit screen at this time corresponds to a state in which the print start button 102 is grayed out in FIG.

  On the other hand, in this embodiment, as shown in FIG. 8B, only a single operation type image correction job in which a test pattern image is measured by a sensor installed (built-in) in the apparatus can be reserved even in the wait state. Control to When the power is turned on at the time 811, the image processing apparatus is in a waiting state for a period 812. In this state, the button of the operation unit can be pressed as shown in FIG. 1D so that the single operation type image correction job can be operated at the time of 814. As a result, the restraint period during which the user is restrained in front of the image processing apparatus is shortened, and the user's ability to instruct execution of image correction is improved.

  The image correction job for which execution has been reserved is executed at the timing when the wait time of the period 812 in the state of the image processing apparatus ends (fixing process stabilization processing ends) and transitions to standby in 813. That is, it is executed during the period 815.

  When the wait time is completed (fixing process stabilization processing is completed), the single operation type image correction job does not require any work by the user, so that even if the user is absent around the image processing apparatus, the image correction job is executed. Can be terminated.

  On the other hand, an interactive image correction job for obtaining a test pattern image measurement result by acquiring a value obtained by reading a test pattern image by a connected reading device (scanner or reader) is executed while the image processing device is in a wait state. Control not to make a reservation. In the case of an interactive image correction job, even if control is performed so that execution of an image correction job can be reserved by a user operation at time 816, printing of a test pattern image is not executed until the standby state is entered.

  Therefore, 817 indicating the work of installing the test pattern image in the scanner unit for reading the test pattern image to be the next user work cannot be executed. Thereby, it is necessary to wait until the standby state is reached, and the user's ability to instruct execution of the image correction job is not improved.

  If it is possible to reserve execution of an interactive image correction job during the wait time, the user waits for the timing when the wait time ends (fixing process stabilization processing ends) and the test pattern image will be printed. It will be necessary to return to the image processing apparatus again. Therefore, there is a possibility of restraining the user's action. Therefore, the interactive image correction job is controlled so that execution reservation cannot be performed during the wait.

  Next, with reference to FIG. 9, a timing chart will be used to explain the control when a normal print job and image correction job reservation operation is performed during the wait time (before completion of the fixing process stabilization process). In the following, it is described that the reservation operation is performed during the wait time. However, the reservation operation is performed before the power input without being limited to the wait time (from the time the power is input until the end of the fixing process stabilization process). May be. For example, a reservation operation for an image correction job that is executed after the power supply is input the next day on the previous day and the fixing process stabilization process is completed may be performed.

  An image correction job that can be reserved by a user operation is limited to a single operation type image correction job. In addition, an image correction job according to an image correction request due to a printer will also be described. First, FIG. 9A shows a case where a normal print job and a single operation type image correction job by a user operation are reserved during the wait. The period 902 immediately after power-on at the time 901 is in a waiting state. At this time, a print job is input at the time 903. In order to submit a print job, it may be submitted using a copy function or a box function from the operation unit of the image processing apparatus, or a PDL print job may be submitted using a printer driver of a PC connected to a network. May be. In this way, the job list of jobs submitted during the wait time may be displayed on the screen of FIG. 5 or the display screen (not shown) of the PC 205.

  In the printing market, when a job is first started, a warm-up operation is performed in order to stably operate the image processing apparatus. The warm-up operation is a break-in operation for operating the electrophotographic process for forming an image in the image processing apparatus to some extent. Specifically, in order to make the fixing temperature constant, the sheet is passed through the fixing device to stabilize the temperature of the fixing device.

  In order to perform such a warm-up operation, a certain number of sheets are passed through the fixing device. Here, the print job input at the time 903 is the printing for the warm-up operation.

  Alternatively, if it is determined that the warm-up operation is not necessary, the print job input at 903 is a normal print job.

  The number of printed sheets used for the warm-up operation can be freely changed according to the job submitted by the user.

  If the user desires to perform image correction after the image processing apparatus has been operated to a certain degree of stability by the warm-up operation, the user can execute a single correction at the time 904 following the job input at the time 903. Submit an execution reservation for the operation-type image correction job. As a result, the time for instructing the execution of image correction is short, and the operation can be easily completed. Therefore, the user's handing when instructing execution of image correction is improved.

  When the wait time of the image processing apparatus ends (fixing process stabilization processing ends), the first input print job is executed in the period 905. The single-type image correction job reserved at the time 904 is executed during the period 907 at the timing when the print job ends and becomes standby in the period 906. Since the user is not required to work during this time, it is not necessary to be restrained in front of the image processing apparatus, and the image correction process can be automatically completed.

  On the other hand, FIG. 9B shows an operation when the image correction job is not a user operation but an image correction request due to a printer is generated. Assume that after the power is turned on at time 908, the wait time is reached in the period 909, and a print job is input at time 910 as before. At this time, the printer status monitoring unit 214 in FIG. 2 detects an image correction request due to the printer at the time 911, and the image correction determination unit 212 submits an image correction job at the time 913.

  In this case, after the end of the wait time (end of the fixing process stabilization process), the image correction job according to the printer request needs to be processed with the highest priority over the print job. Therefore, even if the print job is reserved prior to the image correction due to the printer factor, control is performed so that execution of the image correction job due to the printer factor is given priority during the period 913 when the state transitions to the standby state in 912. When the image correction process executed in 913 is completed, the print job reserved at the time of 910 is executed in 914.

  As described above, the image correction job by the user operation and the image correction job by the printer factor are controlled by switching the order control of the normal print job. That is, if an image correction job by a user operation is reserved for execution after the print job during the wait, the reservation is made first when the wait time ends (fixing process stabilization processing ends) and the standby state is entered. Jobs are executed with priority.

  However, if the image correction job due to the printer is reserved for execution after the normal print job during the wait, the priority is given when the wait time ends (fixing process stabilization processing ends) and the standby state is entered. Then, an image correction job due to printer factors is executed.

  FIG. 10 is a timing chart of processing executed when an image correction job, a printer factor image correction job, and a normal print job are reserved by a user operation.

  Next, with reference to FIG. 10A, a case where a normal print job, a single operation type image correction job, and a printer factor image correction job are reserved for execution during the wait time will be described.

  At 1001, the power is turned on, and the waiting time of 1002 is in progress. At this time, since a normal print job can be reserved, a print job (for warm-up) is reserved and input at 1003. Next, when warming is completed, a user who wants to perform image correction reserves a single operation type image correction job at the time of 1004. Thereafter, it is assumed that a printer factor image correction request is generated and a printer factor image correction job is input at 1005. In this case, since the printer factor image correction has the highest priority, the printer factor image correction is executed during the period 1007 when the state transition is made during standby in 1006. When this is completed, the print job instructed by the user operation previously reserved for execution is executed, and printing is in progress for a period 1008. When this print job is completed and the printer 100 is on standby in 1009, the image correction job reserved for execution by the user operation is executed in the period 1010. Such job order control is performed by the job execution order control unit 211.

  Next, with reference to FIG. 10B, a process when one of the duplicated same image correction jobs is skipped will be described. At 1011, the power is turned on, and the waiting time is 1012. At this time, a single operation type image correction job by a user operation is input at 1013. Thereafter, at 1014, an image correction request due to the printer is generated and an image correction job is reserved. In this case, the image correction job has a plurality of types of correction processing as described above, but the image correction job reserved for execution at the time 1013 and the image correction job reserved for execution at the time 1014 are of the same type. Suppose that In this case, when the wait period ends (fixing process stabilization processing ends) and 1015 enters the standby state, image correction is first performed by an image correction request due to the printer, and then a single operation type image correction job is performed. The However, these image correction jobs differ only in the generation factors, and the correction processing contents are the same. Therefore, if these are executed continuously, redundant processing will be performed. Accordingly, in 1016, one image correction job is skipped and control is performed so that image correction is performed only once. Alternatively, even if the correction processing executed by the printer factor image correction and the single operation type image correction are not all the same, if the same correction processing is included, the same correction processing is executed only once. Thus, the time required for the correction process can be shortened.

  Finally, a summary of the contents of the present embodiment described so far in a flowchart will be described with reference to FIGS.

  In each step of the flowcharts of FIGS. 11 to 13, a control program (not shown) is stored in the storage device 440 included in the main controller 201, loaded into the RAM 406, and executed by the CPU 402.

  FIG. 11 is a flowchart regarding screen control of the operation unit. In step 1101, image correction processing is started. Next, in step 1102, the screen shifts to an image correction processing start screen (FIG. 1B). In step 1103, the printer unit 203 checks whether the test pattern image is ready for printing. If it is determined that printing is possible, the process proceeds to 1104. In this case, because the image is in standby instead of waiting, the image correction start screen is controlled so that the start button for all image correction is enabled, including single operation type image correction jobs and interactive image correction jobs. Do.

  If it is determined in 1103 that it is not in a printable state, that is, it is during the wait time, the process proceeds to 1105. Then, it is determined whether the screen is a start screen for a single operation type image correction job or an interactive image correction job.

  In other words, if the user only gives an execution instruction with a single operation, the user needs multiple operations or operations, whether it is a single operation type image correction job that is an image correction job that does not require any other operation or operation. It is determined whether the job is an interactive image correction job.

  The quick correction and the full correction executed using the sensor 365 in the image processing apparatus when measuring the test pattern are included in the single operation type correction processing job. On the other hand, full correction using the scanner unit 202 (reader 364) without using the sensor 365 when measuring the test pattern is included in the interactive image correction job.

  If it is determined that the screen displayed in FIG. 5 is the start screen when execution of a single operation type image correction job is selected, the process proceeds to step 1106. Then, as shown in FIG. 1D, screen control is performed so that the start button is enabled. On the other hand, if it is determined in step 1105 that the screen displayed in FIG. 5 is the start screen when execution of the interactive image correction job is selected, the process proceeds to 1107. Then, the screen is controlled so as to invalidate the start button as shown in FIG.

  FIG. 12 is a schematic flowchart of the sequence control of the image correction job and the normal job reserved during the wait. This flow is executed when a job is reserved during the wait time.

  When the processing starts at 1201 and the image processing apparatus is waiting at step 1202, it is determined whether an image correction job is reserved. If it is determined that there is neither a job input by a user operation nor a job input due to a printer factor, the process proceeds to step 1206 and ends. If it is determined in step 1202 that there is a job reservation, the process proceeds to 1203. If it is determined that the reserved image correction job is a printer factor image correction job, the process advances to step 1204. In step 1204, after completion of the wait time (fixing process stabilization processing is completed), control is performed so that image correction due to printer factors is executed with priority over normal printing. On the other hand, if it is determined in step 1203 that the image correction job is based on a user instruction rather than a printer factor, the process proceeds to step 1205. In step 1205, after the wait time (fixing process stabilization process ends), control is performed so that image correction and normal printing are executed in the order of input.

  FIG. 13 is a flowchart obtained by further subdividing FIG.

  When the processing starts in step 1301, it is determined in step 1302 whether or not the image processing apparatus is in a wait time. If it is determined that it is during the wait time, the process proceeds to step 1303. In step 1303, it is determined whether the reserved job is a normal print job. If it is determined that the job is a normal print job, the process proceeds to step 1304, the reserved job is queued in a queue processed by FIFO (first in first out), and the process returns to step 1302. If it is determined in step 1303 that the job is not a normal print job, the process proceeds to step 1305. In step 1305, it is determined whether the job is an image correction job according to a user instruction. If it is determined that the image correction job is a user instruction, the process proceeds to step 1306 as in the case of the normal print job, and the image correction job according to the user instruction is queued in the FIFO. If it is determined in step 1305 that the job is not an image correction job according to a user instruction, the image correction job is an image correction request due to an image correction request caused by a printer. In step 1307, control is performed to insert an image correction job in response to an image correction request caused by the printer at the head of the queue. When the wait time in step 1302 ends (fixing process stabilization processing ends) and the wait is released, the process proceeds to step 1308.

  In step 1308, the process moves to the process of executing the job queued during the wait time. If it is determined that there is a job in the FIFO, the process proceeds to step 1309 to analyze the first job in the FIFO. If it is determined that the first job is not an image correction job, the process advances to step 1310 to execute normal printing. After that, after the job that has been executed is deleted from the queue in step 1311, the process returns to step 1308. If it is determined in step 1309 that the first job is an image correction job, the process proceeds to 1312. In step 1312, it is determined whether image correction jobs for performing the same correction process subsequently are queued continuously. If image correction jobs for performing the same correction process are continuous, the image correction process is executed redundantly. Therefore, the duplicated image correction process is deleted from the queue in step 1313 and step 1314 is executed. Transition to.

  That is, when an image correction job due to a printer and an image correction job in accordance with a user instruction are continuously executed, a correction process for correcting the same characteristic is included in the two image correction jobs. The second correction process is wasted).

  Therefore, after the image correction job due to the printer is executed, the correction processing for correcting the same characteristics in the two image correction jobs is not executed in the image correction job according to the user instruction executed within a predetermined time.

  The predetermined time is a preset time, and no other print job is executed at this time.

  In step 1314, the duplication of the image correction processing is eliminated. After performing the image correction that does not overlap here, the process proceeds to step 1315. Then, the job that has been executed in step 1315 is deleted from the queue, and the process returns to step 1308. If it is determined in step 1308 that all the FIFO jobs have been completed, all the jobs reserved during the wait time have been completed, and the process proceeds to step 1316 where the processing ends.

  As described above, since it is possible to make an execution reservation for an image correction process that requires only one user operation among the image correction processes during the wait time, it is easy for the user to instruct the image correction process. In addition, the print job reserved for execution during the wait time and the image correction job reserved for execution during the wait time can be executed in the intended order when the wait time ends (fixing process stabilization processing ends).

  In addition, if it is determined that an image correction job due to a printer is executed during the wait time, after the wait time ends (fixing process stabilization processing ends), the printer factor takes precedence over any job reserved during the wait time. The image correction job is executed. As a result, when the printer determines that the execution is necessary, the image correction process can be executed prior to the printing process, and thus is output after the end of the wait time (end of the fixing process stabilization process). The image quality can be improved.

[Example 2]
In the first embodiment, the timing chart is such that the image correction process is started after the wait time ends (fixing process stabilization process ends) and the wait is canceled. However, it is also possible to adopt a control configuration in which the image correction due to the printer is executed during the wait in order to shorten the time. As a result, the time required to execute the image correction process after the end of the wait time can be reduced as much as possible.

  Therefore, FIG. 14 shows a flowchart in a case where the control for executing the image correction process of the printer factor is executed during the wait time.

  In each step of this flowchart, a control program (not shown) is stored in the storage device 440 included in the main controller 201, loaded into the RAM 406, and executed by the CPU 402.

  Since this flowchart is almost the same as FIG. 13, only different parts will be described.

  If it is determined in step 1405 that a printer factor image correction processing job is reserved, in step 1407, the printer factor image correction job is executed.

  In step 1408, control is performed to hold a history of executing the printer factor image correction job, an image correction job execution flag, and information of the executed image correction content.

  After the wait time is completed and the wait is canceled, it is determined in step 1410 whether the head of the FIFO is an image correction job instructed by the user. If it is determined in step 1410 that the job is not an image correction job, the process advances to step 1411 to execute normal printing. In step 1412, the job executed from the queue is deleted. In this case, since normal printing has been executed, the image correction executed during the wait and the image correction processing executed after the end of the wait and the correction processing content of the correction processing do not overlap (the correction values are the same). Never become). Therefore, in step 1413, the executed flag and the image correction type information are cleared.

  If it is determined in step 1410 that the image correction job is a user instruction, the process advances to step 1414. In step 1414, it is confirmed whether or not there is a record of performing the image correction due to the printer during the wait time, and the information on the executed flag and the image correction type is confirmed. If there is something, go to step 1416. Then, the flag is cleared in step 1416, and the job is deleted from the queue in step 1417 without performing the execution in step 1415. In this way, control is performed so as to avoid redundant execution of image correction jobs.

  Note that, when correction of the same content is executed for only a part of the executed image correction, the job is deleted from the queue only for the correction of the same content, and control is performed so that some processes do not overlap.

  If the executed flag is OFF or the content of the image correction is different even if it is ON, since there is no overlap in the image correction to be executed, control is performed in step 1415 to execute the image correction job according to the user instruction.

  In this flowchart, the image correction job due to the printer is executed during the wait time, so the duplication check process for the same image correction job is different from the flowchart of FIG. However, among the processes executed in the flowchart of FIG. 13, there is a part where the image correction process can be advanced as much as possible, so that the time required for correction can be shortened.

  According to the second embodiment, the same effects as those of the first embodiment can be obtained, and the image correction job due to the printer can be controlled to be executed during a wait time before the image processing apparatus enters a standby state. This makes it possible to shorten the total time required for executing image correction, as compared with the first embodiment.
