Description

  The present invention relates to an image forming apparatus having a print preview display function and a print preview program for causing a computer to execute print preview processing.

An image forming apparatus such as a copying machine or a facsimile machine is based on printing data (image data, print job data, etc.) related to an image for one page or a plurality of pages (hereinafter referred to as a page image) read from an original. Some have a print preview function for displaying an image image (preview image) when a page image is output on a recording sheet (image formation) on a display unit such as a liquid crystal panel. This print preview function is an important function for preventing wasteful image formation against the user's will and suppressing wasteful consumption of recording paper and developer.
For example, Patent Document 1 discloses that when a print result when bookbinding is scheduled and duplex printing is performed is displayed as a preview, each page image is displayed side by side on a display unit.
Patent Document 2 discloses that a plurality of page images (reduced images) are displayed side by side on a display unit in a partially overlapped state.
JP 2004-164105 A JP-A-4-373073

By the way, it is important that the printing result of double-sided printing can confirm both the page order and the front / back relation of each page image by a preview image before printing (image formation). In particular, if you plan to bind (bind) a plurality of recording sheets obtained by double-sided printing, both the page order of each page image and the front / back relationship, and the state of the actually bound recording sheet It is desirable that it can be intuitively confirmed by a preview image.
However, when previewing the printing result of double-sided printing, as shown in Patent Document 1 and Patent Document 2, simply displaying a preview image in which the page images are arranged side-by-side, the page order of each page image and the relationship between the front and back sides of the page image are displayed. There was a problem that it was difficult to grasp both intuitively.
Therefore, the present invention has been made in view of the above circumstances, and the object of the present invention is to provide a preview image that makes it easy to intuitively grasp both the page order and the front / back relation of each page image for the double-sided printing result. Is to provide an image forming apparatus and a print preview program.

In order to achieve the above object, an image forming apparatus according to the present invention uses a print preview image of a page image as a display unit based on print data relating to page images for a plurality of pages stored in a predetermined storage unit. It has a function to display, and further includes each component shown in the following (1) to (3).
(1) Based on information input through a predetermined operation unit, when a double-sided printing is performed based on the printing data, a page of one page image formed on the front surface of the recording material is specified Page identification means to do.
(2) A part of the uppermost recording material from a state in which a plurality of recording materials obtained by performing double-sided printing based on the printing data with the page specified by the page specifying means as the first page First preview output means for causing the display means to display the print preview image including a first turned-up image representing a turned-up state.
(3) In the first flipped image, one or both of an area corresponding to the back surface portion of the uppermost recording material and an area corresponding to the front surface portion of the second recording material. When the image of the repeated exposure area is a blank image, a state in which a part of the page image in the background appears through the recording paper of the area through the repeated exposure area of the first repeated image. Second preview output means for causing the display means to display the print preview image including two repetitive images.

The first turning image displayed by the image forming apparatus according to the present invention is an image that collectively displays at least a part of each of page images for three pages continuous from a specific page. Moreover, the print preview image is an image representing an image when the actual recording material obtained by double-sided printing is turned over with a finger, and “an image corresponding to the front surface portion of the uppermost recording paper” → At first glance, the order of “image of the area corresponding to the back surface portion” → “image of the area corresponding to the front surface portion of the second recording material” represents the page order of the page images. it is obvious. Accordingly, the print preview image displayed by the image forming apparatus according to the present invention is intuitively (immediately) grasped at least at a glance, the contents of the page images for at least three consecutive pages and their page order. It is a possible image.
Further, in the first turned-up image, part of the page images of the second page and the third page are turned over part of the recording material on which the page image of the first page is formed. It is displayed on the part that becomes dew by returning (the repetitive exposure area). Therefore, the first flipped image can be intuitively (immediately determined) to determine how the page images from the first page to the third page are formed on the recording material at a glance. It is an image that can be grasped.
However, when the image of the repeated exposure area in the first repeated image is a blank image (the state where there is no portion developed (developed) by the developer), there is no visible image in the area. In the end, the amount of information obtained from the entire print preview image is reduced by the amount of no visible image in the repetitive exposure area.
On the other hand, in the image forming apparatus according to the present invention, when the image of the repeated exposure area is a blank image, the second image representing a state in which a part of the page image appears through the recording paper in the area. The flipped image is displayed in the print preview image. As a result, the repeated exposure area is effectively used, and the amount of information obtained from the entire print preview image is not reduced. That is, the user can intuitively (immediately) grasp the contents of the image hidden behind the recording material in the repeated exposure area by just looking at the print preview image.
In one recording material on which an image is formed by double-sided printing processing, a surface on which a page image having a relatively smaller page number is formed is a “front surface”, and the page number is relatively The surface on which the larger page image is formed is the “back surface”.

Further, the first preview output means and the second preview output means may be configured such that the page image of the page immediately before the page specified by the page specifying means and the first repeated image or the second It is conceivable that the display means displays the print preview image in which the flipped images are arranged in a spread state.
As a result, a print preview image in which the contents of the page images for at least four consecutive pages, the page order, and the front / back relationship in the recording material can be intuitively displayed is displayed.
Further, the present invention is embodied as a print preview program for causing a computer to execute the process (process for displaying the print preview image on the display unit) executed by the image forming apparatus according to the present invention described above. May be.

  According to the present invention, it is possible to display a preview image that allows the user to intuitively grasp both the page order of each page image and the front / back relationship of the recording material for the printing result of double-sided printing.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that the present invention can be understood. The following embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention.

FIG. 6 is a diagram illustrating a fourth example of a print preview screen in the image forming apparatus X.

An image forming apparatus X according to an embodiment of the present invention is an image forming apparatus such as a copying machine, a printer, or a facsimile machine, and prints a plurality of pages of page images stored in advance in a data storage unit such as a hard disk. A print preview function for displaying a print preview image of the page image on the display unit based on the data for use is provided.
First, the structure of the main part of the image forming apparatus X according to the embodiment of the present invention will be described with reference to the block diagram shown in FIG.
The image forming apparatus X is a so-called multifunction machine having a scanner function, a print function, a copy function, and a facsimile function.
As shown in FIG. 1, the image forming apparatus X includes a main control unit 1, an operation / display unit 2, a data storage unit 3, an image processing calculation unit 4, a NIC 5, a scanner unit 6, a printing unit 7, a facsimile unit 8, and the like. They are connected in such a way that information can be exchanged through the bus 11.
The operation / display unit 2 includes an operation unit 2a for inputting information and a display unit 2b for displaying information (including images). The operation unit 2a is, for example, a touch panel or a sheet key provided on the surface of the liquid crystal display device. The display unit 2b is, for example, a liquid crystal display device. The operation / display unit 2 constitutes a man-machine interface for the user.
The data storage unit 3 is a readable / writable large-capacity non-volatile memory that stores processing data as necessary when processing image data obtained by reading from a document or printing processing of image data. .
The image processing arithmetic unit 4 is constituted by a dedicated signal processing circuit or a DSP (Digital Signal Processor) or the like, performs various image processing on the image data, and forms a print job described in a predetermined print job description language into an image. A process for converting to bitmap image data to be used, a process for generating image data to be transmitted to an external device (for example, image data subjected to predetermined encoding such as JPEG format), and the like are performed.

The NIC 5 receives data (including data of an image read by the scanner unit 6) with an external device such as an information processing terminal or an e-mail server through a network including a LAN and the Internet conforming to the standard IEEE 802.3, for example. It is a communication interface which transmits / receives.
The scanner unit 6 converts an image formed on a document from a document placed on a glass document table (not shown) or a document conveyed by an ADF (not shown) to a color (R, G, B). ) Is a color scanner that distinguishes and reads.
The print unit 7 is a so-called print engine controlled by the main control unit 1, and sequentially feeds recording sheets stored in a sheet feeding cassette (not shown) one by one, and passes through a predetermined image forming position to a sheet discharge tray. Recording paper (recording paper) based on the image data of the original read from the original by the scanner unit 6 and the image data for printing generated by the image processing calculation unit 4 at the image forming position. It is a set of components such as a device that forms (outputs) an image on an example) and an MPU that controls the device. The printing unit 7 has a function of executing double-sided printing processing for forming an image on both the front surface and the back surface of the recording paper.
The facsimile unit 8 includes communication means such as an NCU (Network Control Unit) and a modem, and performs dial-up and negotiation processing for determining a communication method with a communication partner (partner station). It transmits and receives facsimile data (image data read by the scanner unit 6) with the facsimile apparatus.

The main control unit 1 controls each of the scanner unit 6, the print unit 7, the facsimile unit 8, the operation / display unit 2, the data storage unit 3, and the image processing calculation unit 4.
For example, the main control unit 1 causes the printing unit 7 to execute a printing process (image forming process) based on a print job received through the NIC 5. Further, the main control unit 1 causes the facsimile unit 8 to execute a facsimile transmission process for calling a designated transmission destination telephone number and transmitting image data to be transmitted. Further, the main control unit 1 causes the scanner unit 6 to execute a scanning process for reading an image formed on the original from the original.
Further, the main control unit 1 is based on printing data (image data, print job data, etc.) relating to an image for one page or a plurality of pages (hereinafter referred to as page image) read from the document by the scanner unit 6. Print preview processing is also executed for causing the display unit 2b to display an image image (preview image) when the page image is output (image formation) to the recording paper.

Next, the procedure of the print preview process executed by the image processing apparatus X will be described with reference to the flowchart shown in FIG. 2 and the print preview screen examples shown in FIGS.
It is assumed that printing data is stored in advance in the data storage unit 3 before the processing shown in FIG. As described above, the print data is a print job input from the external device through the NIC 5 or image data read by the scanner unit 6. S1, S2,... Shown below represent identification symbols of processing procedures (steps).

[Steps S1 to S4]
First, the main control unit 1 displays a predetermined initial menu screen on the display unit 2b (S1), and monitors whether or not an operation for selecting a processing item in the initial menu has been performed through the operation unit 2a (S2). ).
When the main control unit 1 detects that an operation for selecting any processing item is performed during the display of the initial menu, the main control unit 1 executes a process corresponding to the operation.
That is, when the operation for the initial menu is an operation for requesting print preview display processing (print preview operation), the main control unit 1 sets an initial value (= 1) for a variable i representing a page number. Above (S3), it is determined whether or not the printing data stored as a processing target in the data storage unit 3 is data for double-sided printing that has been selected in advance as a target for double-sided printing (S4). .
The double-sided printing data is print job data or read image data relating to page images for a plurality of pages.
The variable i represents a page of one page image formed on the front surface of the recording paper when double-sided printing based on double-sided printing data described later is performed. In this embodiment, the value of the variable i is an odd value of 1 or more. In addition, the main controller 1 that executes the process of step S3 specifies the value of the variable i based on information (information requesting print preview display) input through the operation unit 2a. It is an example.

[Steps S5 and S6]
When the main control unit 1 determines in step S4 that the printing data is double-sided printing data, the main control unit 1 selects pages (i-1) to (i + 2) based on the double-sided printing data. Data is generated for page images for four pages (S5). In step S5, it is needless to say that image data relating to pages not included in the double-sided printing data among the page images for four pages from the (i-1) page to the (i + 2) page is not generated. .
Next, the main control unit 1 determines whether the display mode of the print preview is “normal mode” or “watermark mode” (S6). More specifically, the main control unit 1 determines in advance an image of a predetermined area (hereinafter referred to as a first repeated exposure area) in a page image of (i + 1) page and a page image of (i + 2) page. The print preview display mode is set to “normal mode” by determining whether or not one or both (at least one) of the image in the defined area (hereinafter referred to as the second repeated exposure area) is a blank image. "Or" watermark mode "is discriminated (S6). That is, if one or both of the first repeated exposure area and the second repeated exposure area is a blank image, it is determined to be “watermark mode”, and in other cases, it is determined to be “standard mode”. To do. Here, the blank image means a state in which there is no portion developed (developed) by the developer in the image area.
The display mode is information for identifying what type of print preview image is to be displayed on the display unit 2b in the print preview image display process based on the double-sided printing data. Will be described later. In addition, the areas of the first repeated exposure area and the second repeated exposure area will be described later.

[Step S7]
When the main control unit 1 determines that the display mode is the “normal mode”, that is, when neither the first repeated exposure area nor the second repeated exposure area is a blank image, the main control unit 1 performs step S5. Based on the generated page image data for four pages from the (i-1) page to the (i + 2) page, the print preview image data for the “normal mode” is generated, and the print preview image is displayed on the display unit. 2b.
3 and 4 are examples of display screens of print preview images for the “normal mode”. FIG. 3 shows an example in which there is no page image of (i−1) page because page variable i = 1, and FIG. 4 shows that page variable i = 3 and (i−1) from page (i + 2). ) This is an example in the case where there are four page images up to (2 to 5 pages).

As shown in FIGS. 3 and 4, the print preview image displayed on the display unit 2 b by the main control unit 1 (an example of the first preview output unit) is the process of step S <b> 3 or step S <b> 11 described later ( Top page (i-th page) from a state in which a plurality of recording materials obtained by performing double-sided printing based on the double-sided printing data with the page specified by the example of processing of page specifying means as the first page. The recording material includes an image (hereinafter, referred to as a first turned image g1) representing a state in which a part of the recording material (for example, the lower right portion) is turned over. Therefore, the first flipped image g1 includes the first area p1 corresponding to the front surface (i-th page) portion of the uppermost recording paper, and the back surface (i + 1 page) of the uppermost recording material. The second region p2 corresponding to the (eye) portion and the third region p3 corresponding to the front surface (i + 2nd page) portion of the second recording material are present.
The main control unit 1 sets (specifies) each of the first to third regions p1 to p3 in the first turned-up image g1 by the process of step S3 described above or step S11 described later. A part g12, g22, and g32 of each of the page images for three pages from the i page are displayed.

More specifically, regardless of the display mode, the main control unit 1 applies the double-sided printing process based on the double-sided printing data to the first region p1 in the first repeated image g1. The image g12 (part of the page image) formed as it is in the remaining portion excluding the portion corresponding to the first region p1, that is, the portion of the page image of the i-th page that is hidden by turning over the recording paper is displayed as it is. Let
In the normal mode, the main control unit 1 performs duplex printing based on the duplex printing data on each of the second area p2 and the third area p3 in the first repeated image g1. The part g22 and g32 of the page image formed in portions corresponding to the second region p2 and the third region p3 are displayed as they are. Thus, in the example shown in FIG. 4, the image g22 at the lower left corner of the page image of the (i + 1) th page is in the second area p2, and the (i + 2) th page is in the third area p3. Images g32 in the lower right corner of the page image are displayed.
Further, the main control unit 1 also displays page number information g11, g21, g31 corresponding to each region in each of the first to third regions p1 to p3.
Further, as shown in FIG. 4, the main control unit 1 arranges the page image g0 of the (i-1) page immediately before the i page and the first turned-up image g1 in a spread state. A print preview image is displayed on the display unit 2b (S7).
Further, the main control unit 1 displays a display target page changing operation button g4 and an end button g6 together with the print preview image on the display unit 2b which is also used as the operation unit 2a (S7). .

By the way, in the first repeated image g1 shown in FIGS. 3 and 4, the second region p2 (a substantially triangular region corresponding to the back surface portion of the uppermost recording material) is the first repeated exposure. The third region p3 (a substantially triangular region corresponding to the front surface portion of the second recording material) is the second repeated exposure region.
Therefore, in step S6, as shown in FIGS. 3 and 4, the main control unit 1 makes both the second area p2 and the third area p3 in the first repeated image g1 blank. If the image is not an image (the visible images g22 and g32 exist), it is determined that the display mode is the “normal mode”. Similarly, in step S6, the main controller 1 displays the display when one or both of the second region p2 and the third region p3 in the first repeated image g1 are blank images. It is determined that the mode is “watermark mode”.

[Step S8]
On the other hand, when it is determined that the display mode is the “watermark mode”, the main control unit 1 first sets (specifies) the image processing calculation unit 4 in the above-described step S3 or the processing in step S11 described later. The area determined as the blank image area in step S6 from the second area p2 and the third area p3 from the page images of the i-th page and the (i + 3) -th page (the repeated exposure area). That is, an image of a portion corresponding to (i.e., an image that appears when the recording paper in the blank image area is seen through) (hereinafter referred to as a background image) is extracted (S8).
Further, the main control unit 1 causes the image processing calculation unit 4 to generate data of an image (hereinafter referred to as a watermark background image) representing an image when the background image is viewed through the recording paper (S8). . For example, the watermark background image is obtained by applying a shading process to the background image, lowering the density of the background image by a predetermined ratio, or thinning out some pixels in the background image (for each pixel at a fixed interval). This is an image obtained by performing a process of setting the density value to zero.

[Step S9]
When the main control unit 1 determines that the display mode is the “watermark mode”, the page image data for four pages from the (i−1) page to the (i + 2) page generated in step S5, and Based on the watermark background image data generated in step S8, print watermark image data for "watermark mode" is generated, and the print preview image is displayed on the display unit 2b (S9).
FIG. 5 shows an example of a print preview image display screen for the “watermark mode”. FIG. 5 shows an example in which the page variable i = 3 and there are three page images (Page-2, 3, 6) of (i-1) page, i page, and (i + 3) page.
As shown in FIG. 5, the print preview image for “watermark mode” includes the first repeated exposure area (second area P2) and the second second repeated image g1 in the first repeated image g1. In a repeated exposure area (the third area P3), a state in which the recording paper in that area is seen through and a part of the page image in the back appears (a state in which the back watermark images g23 and g33 are displayed). 2 turning images g1x are included. In the second flipped image g1x shown in FIG. 5, areas corresponding to the first to third areas P1 to P3 in the first flipped image g1 shown in FIG. 3 regions P1x to P3x.
Even in the “watermark mode”, the main control unit 1 applies the first area p1x in the second turned-up image g1x to the first area p1x by the double-sided printing process based on the double-sided printing data. The image g12 (a part of the page image) formed in the remaining portion excluding the corresponding portion, that is, the portion hidden in the page image of the i-th page by turning over the recording paper is displayed as it is (S9).
On the other hand, the main control unit 1 applies the background of the watermark generated by the image processing calculation unit 4 in step S8 to each of the second region p2x and the third region p3x in the second turned-up image g1x. Each of the images g23 and g33 and the page number information g24 and g34 of the page image that is the basis of the watermark behind images g23 and g33 are displayed (S9, an example of the second preview output means).
Further, as shown in FIG. 5, the main control unit 1 arranges the page image g0 of the (i-1) page immediately before the i page and the second flipped image g1x in a spread state. A print preview image is displayed on the display unit 2b (S9).
Since the watermark behind images g23 and g33 are displayed in the second repeated image g1x, the first repeated exposure area in the page image of (i + 1) page (4 pages in the example of FIG. 5). The image of the portion corresponding to (the second region P2) and the second repeated exposure region (the third region P3) in the page image of the (i + 2) page (5 pages in the example of FIG. 5). It can be seen that the corresponding image is a blank image.
In addition, the first and second repeated exposure areas P2 and P3 are effectively used, and the amount of information obtained from the entire print preview image is not reduced. That is, the user can intuitively (immediately) grasp the contents of the image hidden behind the recording material in the first and second repeated exposure areas P2 and P3 by just looking at the print preview image. it can.

[Steps S10 and S11]
Then, after the process of step S7 or S9 is completed, the main control unit 1 monitors whether any of the operation buttons g4 to g6 has been operated through the operation unit 2a (S10), and according to the operation content. Execute the process.
That is, when the operation button g4 for changing the display target page (page change operation) is performed, the main control unit 1 changes the value of the variable i (page number) according to the operation (S11), and newly For the set page i, the processes in steps S5 to S9 described above are executed.
For example, when the main control unit 1 detects an operation of the previous page button or the next page button among the change operation buttons g4 for the display target page in step S11, the main control unit 1 subtracts the value of the variable i (−2) or Add (+2). Further, when detecting the operation of the first page button or the last page button, the main control unit 1 sets the value of the variable to 1 or the value of the last odd page in the duplex printing data. In addition, when a page is directly designated by the operation of a numerical key (not shown), the main control unit 1 designates the value of the designated page if the designated page is an odd number, and designates the specified page even if the designated page is an even number. A value obtained by adding 1 to the page is set as a variable i.
As described above, the main control unit 1 sets the front side of the recording paper when double-sided printing based on the double-sided printing data is performed based on the information input through the operation unit 2a in step S11. A page of one page image formed on the surface is set (specified) (an example of the page specifying unit).

[Steps S20 and S21]
In step S10, when the main control unit 1 detects that the end button g6 has been operated (end operation), the process returns to step S1 described above. Thereby, the process from step S1 mentioned above is repeated.
On the other hand, when the main control unit 1 detects an operation other than the print preview operation during the display of the initial menu in step S2, the main control unit 1 executes other processing according to the operation content (S20). , The process returns to step S1 described above.
Further, in step S4, the main control unit 1 is the single-sided printing data in which the printing data stored as the processing target in the data storage unit 3 is selected in advance as a single-sided printing target (see above). If it is determined that the data is not double-sided printing data, print preview processing of the single-sided printing data is executed (S21), and then the process returns to step S1 described above. Note that the processing in step S21 is not particularly related to the processing according to the present invention, and thus the description thereof is omitted here.

The image forming apparatus X described above displays a print preview image including the first flipped image g1 as shown in, for example, FIG. 3 or FIG. 4 on the display unit 2b. It is easy to intuitively grasp both the page order of each page image and the front / back relationship on the recording paper.
Further, the main control unit 1 responds to an input of an operation button (for example, button g7 in FIG. 6) for selecting whether or not to display the first turning image g1 or the second turning image g1x. Thus, either the print preview image including the flipped images g1 and g1x as shown in FIGS. 3 to 5 or the print preview image not including the flipped images g1 and g1x as shown in FIG. It is also conceivable to switch whether to display on the screen. The example shown in FIG. 6 is an example in which a print preview image in which the page image g0 of page (i-1) and the page image g1 ′ of page i are arranged in a spread state is displayed on the display unit 2b.

In the example shown in FIGS. 3 to 5, the flipped images g1 and g1x represent a state in which the lower right portion of the recording paper is turned over. It is also conceivable to display the turn-up image representing a state in which a part including the upper right portion of the recording paper or the like is turned over and included in a print preview image.
Further, the present invention may be realized as a print preview program that causes a computer such as a personal computer to execute the process shown in FIG. 2 executed by the image forming apparatus X described above.
For example, before the computer transmits a print job to the printer, the computer executes the print preview program, so that the print preview image as shown in FIGS. 3 to 5 is displayed on the graphic display (display unit). It is conceivable to display.

In the example shown in FIG. 5, the second flipped image g1x is an image in which the image of the first flipped exposure area (the second area P2) in the first flipped image g1 is a blank image. In the above example, the background watermark image based on the page image of i page is displayed in the area. However, a part of the page image of (i + 1) page (for example, Page-4) is displayed in the area. It is also conceivable to display the second turned image in a transparent state on the display unit 2b.
Similarly, in the example shown in FIG. 5, the second turned-up image g1x is a blank image of the second turned-up exposed area (the third area P3) in the first turned-up image g1. In the case where the image is an image, the background watermark image based on the page image of the (i + 3) page is displayed in the area. However, the page image of the (i + 4) page (for example, Page-7) is displayed in the area. It is also conceivable to display the second flipped image in a state in which a part thereof is seen through on the display unit 2b.

  The present invention can be used for an image forming apparatus and a program for causing a computer to execute print preview display processing.
