Description

  The present invention relates to an image forming apparatus that outputs an image, and more particularly to a technique for performing test printing when outputting an image.

In general, before outputting a large number of copies in an image forming apparatus such as a copying machine, test printing is performed in which only one or a plurality of originals subjected to image processing according to appropriate image processing conditions are printed first. , The print result may be confirmed. If the intended print result cannot be obtained by looking at the result of the test print as described above, change the setting for printing the original and perform the test print again. If the intended print result is obtained, By printing the remaining number of originals at once according to the image processing conditions obtained as a result, it is possible to prevent misprinting at the time of mass printing and suppress wasteful consumption of paper and toner.
As a related technology, at the time of trial printing, one page is divided into a plurality of areas, and a document is printed with different density settings step by step for each area, thereby making it possible to determine the print result based on the gradation of each density. The technique is disclosed in Patent Document 1. Further, Patent Document 2 discloses a technique that allows an individual identification number to be assigned to each page printed by trial printing, and allows printing under different conditions for each page.

Further, when generating / changing a plurality of image processing conditions, the main control unit 18 generates image processing conditions in which the type of image processing conditions selected by the operation unit 16 is changed in a plurality of stages. , Generating a plurality of stages of the image processing conditions in which the on / off state of the selected type is switched, or changing the image processing conditions by changing the setting stage of the type specified by the operation unit 16. . Further, the main control unit 18 assigns identification numbers (ID) corresponding to the plurality of generated image processing conditions to the image processing conditions. Further, when the operation unit 16 selects to store the image processing condition, the main control unit 18 stores the image processing condition in the setting condition storage unit 15. The main control unit 18 is an example of a processing condition generation unit.

Next, with reference to the flowchart of FIG. 2, an example of a processing procedure for trial printing of image data of a document with the main control unit 18 of the copying machine X as a center will be described. S101, S102,... Shown below represent identification codes of processing procedures (steps).
Prior to the following processing, it is assumed that standard image processing conditions and identification information (ID) corresponding to the conditions are stored in the setting condition storage unit 15 of the copying machine X in advance.
For example, data such as density 70%, contrast 30%, sharpness 40%, saturation 60%, etc., or data in which these image processing conditions are set stepwise for each type (density 50% and 70%, contrast 30 It is assumed that identification information in which data such as% and 50%, sharpness 40% and 60%, saturation 60%,...
First, a document to be printed by the user is set on the scanner unit 11, and a reading instruction is sent from the operation unit 16 to the main control unit 18. The main control unit 18 reads a document set on the scanner unit 11, and stores the image data of the read document in the image data storage unit 12 (step S101). Next, the main control unit 18 displays on the display unit 17 that it should be selected whether or not to perform test printing on the read image data (step S102).
When it is selected not to perform the test printing (step S102; NO), the main control unit 18 indicates whether or not to print (main printing) the image data read into the display unit 17. It is displayed (step S109).
If it is selected in step S102 to perform test printing (step S102; YES), the main control unit 18 stores a plurality of standard (initially set) stored in the setting condition storage unit 15. The image processing conditions are read out, and the display unit 17 is displayed to select whether to perform trial printing based on the plurality of image processing conditions or to generate / change the default image processing conditions by the user (step S103). .
When the user chooses to set (step S103; user setting), the main control unit 18 sets a plurality of types of image processing conditions to be selected by the user or each type of image processing conditions to be changed by the user. The setting stage or the on / off state is displayed on the display unit 17. When the user selects a type to be used, the main control unit 18 generates a plurality of stages of image processing conditions by changing the selected type into a plurality of stages. When the user instructs to change the setting stage for each type of displayed image processing condition, the main control unit 18 changes the setting stage for the type of image processing condition indicated (step S104). The generated image processing conditions are temporarily stored in the setting condition storage unit 15.
For example, when “density” is selected as the type to be used, five image processing conditions changed to density levels “1 to 5” are generated. In addition, when “density” and “sharpness” are selected as the types to be used, density levels “1, 3, 5”, which are representative values obtained by equally dividing the levels of each type, Nine image processing conditions combining the sharpness stages “1, 3, 5” are generated. When “density” is selected as the type to be used and “3, 5” is selected as the setting stage, two image processing conditions set at the density stages “3” and “5” are generated.
Thereafter, the main control unit 18 assigns identification information (ID) for each of the plurality of image processing conditions (step S105). The assigned identification information is also temporarily stored in the setting condition storage unit 15.
On the other hand, when it is selected to read the standard setting (step S103; read), the main control unit 18 reads a plurality of standard image processing conditions stored in the setting condition storage unit 15 (or stepwise thereof). ) And identification information (ID) corresponding to the image processing conditions are read (step S106).
When the image processing conditions and the identification information (ID) corresponding to the image processing conditions are obtained (steps S105 and S106), the main control unit 18 applies to a part of the image data stored in the image data storage unit 12. Thus, the image processing unit 13 performs different processing according to the plurality of image processing conditions generated in the step S105 or read out in the step S106, and the image processing condition is set in the blank portion of the image processed image data. Corresponding identification information (ID) is synthesized.
Further, as shown in FIG. 3, the main control unit 18 outputs a plurality of pieces of image data processed by the image processing unit 13 under different image processing conditions and combined with the identification information of the image processing conditions to the image output unit 14 ( Printing) (step S107). The main control unit 18 may display a plurality of image data on the display unit 17 instead of causing the image output unit 14 to output the image data.
When the image is output, the main control unit 18 changes the type of the image processing condition used for printing the image data to generate / change the image processing condition, or any one of the image processing conditions used for printing. Is displayed on the display unit 17 to select whether or not to change the set stage (step S108).
When the user instructs the main control unit 18 to change (step S108; YES), the processes after step S104 are repeated again.
When the user instructs the main control unit 18 not to change via the operation unit 16 (step S108; NO), the main control unit 18 determines whether or not to perform the main printing as shown in FIG. When printing is performed, the display unit 17 displays that the identification information (ID) assigned to the image processing conditions should be input (step S109).
At this time, the user can see the printed material in which the identification information related to the trial printing is combined, and can know the identification information combined with the printed material most intended.
Therefore, when the user inputs some identification information in the input window in FIG. 4 in this state, it is determined that the input identification information is identification information combined with a printed matter that is intended for the user. be able to. Therefore, the main control unit 18 determines whether or not the identification information (ID) is input within a predetermined time (step S109), and when the identification information (ID) is input within the predetermined time (step S109). S109; YES), since it is considered that the printed material image-processed according to the image processing conditions corresponding to the input identification information is a printed material based on the conditions desired by the user, the main control unit 18 does not perform the predetermined time. It is determined whether or not full printing has been selected (step S110, whether or not the setting button displayed in FIG. 4 has been pressed).
When main printing is thus selected (step S110; YES), the main control unit 18 causes the image processing unit 13 to perform image processing according to the image processing conditions corresponding to the identification information (ID) input in step S109. The image data is processed, and the processed image data is output to the image output unit 14 for all sheets. The main control unit 18 causes the image output unit 14 to print image data (step S111).
When printing is finished, the main control unit 18 displays on the display unit 17 that it should be selected whether or not to store the newly generated image processing conditions (step S112). When the user instructs the main control unit 18 to save (step S112; YES), the main control unit 18 assigns an identification number to the image processing condition for which the identification information (ID) is selected as a new standard setting. Thus, the image processing conditions that are permanently stored in the setting condition storage unit 15 and for which no identification information (ID) has been selected are deleted from the setting condition storage unit 15 (step S113).
When the identification information is not input within a predetermined time (step S109; NO), or when the setting button of FIG. 4 is not pressed within the predetermined time, that is, when the main printing is not performed (step S110; NO), it is generated after printing. When the image processing conditions are not stored (step S112; NO) and when the new standard settings are stored (step S113), the process is terminated.

In step S104, the method of changing the type selected by the user has been described. However, the type selected by the user is fixed to a certain value, and the other types are changed at each stage to generate image processing conditions. Also good.
For example, when outputting image data of a photo, select “color tone”, “color balance / (each color)”, etc., and fix them to the values set by the user, and select “Contrast”, “ A plurality of image processing conditions may be generated in which “sharpness”, “saturation”, etc. are changed and combined at each stage.

As described above, according to the copying machine X, the identification information of the image processing conditions formed in the output image can be acquired at the time of trial printing, so that it is formed in the output image closest to the user's intention. The user can obtain the output image intended by the user simply by inputting the identification information, and the labor of inputting the image processing conditions many times by trial and error is saved, and the labor of inputting the image processing conditions one by one is saved. As a result, it is possible to provide an image forming apparatus that has no failure and is extremely labor-saving.
In addition, since the image processing condition can be designated to the image forming apparatus by inputting the identification number (ID) added to the image data output at the time of trial printing when performing the main printing, the selected image processing It is possible to prevent the main printing from being performed under conditions different from the conditions.

In the first embodiment, another example of the process of step S104 will be described with reference to FIG.
Specifically, in step S104, the main control unit 18 stores the setting change history of the type used for setting in the setting condition storage unit 15, and is generated when the user generates image processing conditions. The image processing condition having a high frequency is displayed on the display unit 17. When the user selects the displayed type, the selected type is changed to multiple levels, and the other types not selected are also changed to multiple levels based on the frequency information. Is generated.
In this case, it is possible to prevent image formation based on unnecessary image processing conditions by automatically adopting the generated image processing conditions with high frequency as the image processing conditions for the next trial printing. is there.
For example, it is assumed that the types of image processing conditions of “ground color removal”, “density”, “sharpness”, and “contrast” are recorded in the setting change history as types of image processing conditions that are generated with high frequency. . Here, when it is selected in step S103 that the user sets or changes the setting (step S103; user setting), the main control unit 18 displays the setting change history as shown in FIG. Based on this, the type of frequently used image processing condition is displayed on the display unit 17. Here, when the type of image processing condition “background color removal” is selected, as shown in FIG. 6, the on / off state of “background color removal” is switched and the condition types “density”, “sharpness”, Six image processing conditions in which “contrast” is changed to each representative stage are generated.
As a result, it is possible to easily generate an image processing condition in which the type of image processing condition that is frequently used is changed, so that it is possible to easily find the image processing condition most suitable for the purpose of printing.

In the second embodiment, another example of the process of step S106 will be described with reference to FIG.
Specifically, in step S106, the main control unit 18 reads a plurality of image processing conditions stored in the setting condition storage unit 15, and each type of stage or on / off state is read for each read image processing condition. The state is displayed on the display unit 17.
Next, the user selects one of the plurality of read image processing conditions, and further selects and changes the type of the image processing condition to be changed from among the plurality of types of the selected image processing conditions. The main control unit 18 is instructed on the condition type. The main control unit 18 generates a plurality of image processing conditions in which the type of the image processing condition instructed to be changed is changed into a plurality of stages or switches the on / off state, and adds identification information to the image processing condition. .
For example, when there are three sets of image processing conditions as the read standard settings, five image processings in which the stage of the type “density” of one of the standard setting image processing conditions is changed to “1-5” Create a new condition.
This makes it possible to generate multiple image processing conditions that change only the types that the user places importance on, based on the standard settings, and can print under different conditions with a simple operation. Image processing conditions can be found.

In the third embodiment, a function of outputting a plurality of processed image data as a single unit will be described.
In the third embodiment, the image processing unit 13 generates image data according to the plurality of image processing conditions stored in the setting condition storage unit 15 and then reduces each of the image data subjected to image processing. In addition, a small image generation / display function is also provided which generates the same image data by assigning them equally.
With reference to FIG. 2, another example of the process of step S107 will be described as a specific example.
In step S107, the main control unit 18 performs a different process on a part of the image data according to the plurality of image processing conditions, and then reduces and evenly assigns the processed image data. The image output means outputs the image data as a single image data.
Specifically, in step S107, the main control unit 18 generates a plurality of image data processed by a plurality of image processing conditions for one image data in the image processing unit 13, and the generated image Data is reduced and evenly allocated to form one image data. Next, as shown in FIG. 7, the main control unit 18 causes the image output unit 14 to output the image data generated by the image processing unit 13.
As a result, the number of sheets output during trial printing can be reduced, and the cost for trial printing can be reduced. In particular, when you want to check the hue and color balance when you try to print image data of a photo, you can grasp the image of the entire image even if it is reduced, and the amount of expensive photo printing paper used Can be suppressed.

  As described above, the present invention can be applied to an image forming apparatus.
