Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mount input device used in a plate making process for printing magazines, catalogs, leaflets, etc. The present invention relates to a mount input device that enables easy input.

[0002]

2. Description of the Related Art In recent years, a plate making method for printing has been remarkably developed. Editing work such as image trimming and layout can now be performed using a computer (using digital data). In such a system, image data is read from a photographic original (film) using an image input means such as a rotary drum scanner. The read image data is once stored as digital data in a memory such as a magnetic disk. The editing work of trimming and layout is to specify at which position on the page a photo, a character, a graphic or the like is to be assigned.

Generally, in printed matter such as magazines, photo albums, leaflets, and posters, layouts such as photographs, characters, and logo marks are always specified for all pages. In such a plate making process and design layout, a mount is used as a layout designating paper when laying out photographs and characters. The mount is a standard for the size of the printed matter. A graphic frame and ruled lines with an appropriate width are drawn on the mount in the original size. Further, characters and the like stamped on the photographic paper in a predetermined series are attached to the mount.
By tracing the image on the mount using a CAD system or the like, coordinate data of a layout frame or a figure of the photograph is input. The image stored in the memory such as the magnetic disk is arranged for the data thus input, and the color is designated for the figure. Further, regarding the characters, a method of manually attaching the characters to the plate-making film has been adopted in a separate step.

However, such a method requires a complicated and long-time proficient operation in which the operator manually pastes the characters and colors them. Further, due to the shortage of operators, it has been difficult to promptly deal with the correction in this case.

In a total scanner device developed to improve this point, the mount itself having the layout designation is read by a flatbed scanner or the like, a layout frame, characters and the like are extracted, and an image including the characters and the like is formed. A method (complete stencil printing) in which a color is designated and a photograph or the like which has been previously input as a digital image is fitted into a layout frame is adopted.

After that, a layout calculation process is performed on each digital data arranged on the screen, and a paper surface (layout image) to be actually printed is output as a hard copy such as a plate-making film.

[0007]

However, in such a conventional mount input device, when the mount data is input by the flatbed scanner and the mount is tilted and set on the reading surface of the scanner, the following will occur. There was an inconvenience. That is, if the mount data is read from the tilted mount, there is a problem that the operator needs to determine the rotation angle of the mount and correct the read data based on this rotation angle. Alternatively, there is an inconvenience that it is necessary to reset the mount and re-input.

After this correction, layout data such as a plate-making layout instruction is added to the read mount data, but this work also requires some time, and the total scanner device is occupied during this time. It was That is, the operating rate of the expensive total scanner device has been reduced.

Therefore, for data that is relatively easy to input as coordinate data such as trimming frames, a method of tracing and inputting a mount with a system such as CAD has been adopted. In this case, this coordinate data is set as one point on the mount data that has already been input (one corner of the plate making frame) as the origin, and is matched with the mount data.

However, the coordinate data obtained by the CAD input and the mount data obtained by the scanner input are inevitably displaced from each other due to the expansion and contraction of the paper mount.
In this case, the mount data may be scaled,
The photographic printing paper stuck on the mount did not shrink, and the series of characters deviated, and uniform scaling processing was also impossible. Fig. 6 shows the mount and the size and figures of the board that should actually be made. When the origin is set at the lower left corner of the plate making frame, for example, the figure to be located in the center is laid out with a large shift to the left. It is a thing.

[0011]

SUMMARY OF THE INVENTION Therefore, the present invention has been made to solve the above-mentioned problems, and provides a mount input device capable of performing accurate trimming and layout easily in a short time, and at the same time, an expensive total scanner device is provided. Its purpose is to increase the utilization rate.

[0015]

According to the mount input device according to the first aspect of the present invention, layout data including plate making frame data, image data for plate making, and plate making data are input. Further, the mount data including the plate making frame data is read from the mount, and the read mount data is corrected based on the input layout data. Then, based on the layout data, the image data, and the corrected mount data, output data for plate making is created and output.

According to the second aspect of the present invention, the read mount data is corrected so that the center point of the plate making frame based on the mount data coincides with the center point of the plate making frame based on the layout data. As a result, it is possible to reduce the deviation between the mount data and the layout data regardless of the expansion and contraction of the mount, and it is possible to output the platemaking data with less deviation. Further, according to the invention of claim 3,

[0017]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 are for explaining a mount input device according to an embodiment of the present invention.

FIG. 1 is a block diagram showing the overall construction of a mount input device according to an embodiment of the present invention. This apparatus includes image input means 11 such as a drum type scanner or a flatbed scanner for inputting image data of film or the like, a first storage means 12 for storing the image data, and layout data for inputting layout data. Input means 1
3, a second storage means 14 for collectively managing the layout data thereof, a flatbed type mount input means 15 for inputting mount data, and a third storage for storing the mount data. It is composed of a means 16, a central processing unit (CPU or the like) 17 for performing overall processing, a control device 17a, a display 18, an output device 19, a mouse 20, and a keyboard 21. The first to third storage means 12, 14, 16 are composed of a magnetic disk unit or a magneto-optical disk unit. The image input means is not limited to the flatbed type or drum type image scanner, but a CCD type camera, a video signal output type camera, a flying spot type scanner, or the like can be used.

The mount input means 15 composed of a flatbed scanner reads the original images such as line drawings, characters and photographs drawn on the mount. On this mount, a line drawing for designating the arrangement of photographs and characters on the printed matter is drawn. For example, a table, a layout frame, and the like are drawn at predetermined positions on the mount. This image scanner has a transparent glass surface, and a mount is placed on the glass surface with its image surface facing downward. The light-shielding door positions the mount on the glass surface, and blocks light from the outside of the image scanner. The image scanner having such a configuration reads the mount while scanning the mount in a predetermined direction, and outputs the read image as gradation image data represented by gradation data for each of a plurality of pixels.

The gradation image data output from the image scanner is input to the central processing unit 17.
The central processing unit 17 and the control unit 17a perform processing such as binarization of gradation image data, identification of line drawings, characters, etc., and calculation of line width (length of ruled line) for the binarized image data. It is something to do. A display 18 is connected to the central processing unit 17. Display 18
Is for displaying an image represented by gradation image data or binary image data.

In the mount input device having the above configuration, the mount is read by the image scanner 15. The read image on the mount is output to the central processing unit 17 as image data representing a gray scale. The central processing unit 17 binarizes this gradation image data, generates binary image data, and displays it on the display 18. Then, the image data is corrected based on the binary image data. For example, the image data input from the mount input unit 15 is corrected based on the layout data input by the layout data input unit 13. Specifically, the center point is calculated based on the coordinate data indicating the plate making frame included in the layout data, and the center point of the plate making frame based on the image data directly input from the mount is made to coincide with this center point.
This image data is corrected. Further, the central processing unit 17 adds additional data (data for plate making) designating printing of a product photograph or the like within the layout frame in the binary image data. After that, the image data representing the product photograph (data that has been separately read) is fitted into the layout frame of the binary image data, whereby the data for plate-making output is created.

The procedure of the mount input device will be described below with reference to FIGS.
Will be described in detail. First of all, the worker must take a photo manuscript at the time when the photo manuscript and the layout instructions are submitted, or at the time when a copy of the photo manuscript showing only the magnification and trimming range instructions of the photo manuscript is submitted. From the image input means 11 as digital image data (f
1). This digital image data is given to the central processing unit 17 and the control unit 17a. The control device 17a stores this digital image data in the storage means 12 such as a hard disk.

Next, the graphic data such as the plate-making frame of the mount and the trimming frame of the photograph are given the coordinate position data based on the block mount from the layout data input means 13 such as a digitizer (f2). Further, a plate making instruction by the operator is input from the input means such as the mouse 20 and the keyboard 21. This layout data is collectively managed by the storage means 14.

Next, the mount data is read from the mount (f
3). That is, the mount is set on the flatbed scanner (mount input means) 15 and the original image (including the plate making frame) such as characters and line drawings drawn on the mount is read. The read mount data is given to the central processing unit (CPU) 17 and stored in the mount data storage means 16. This mount data is displayed on the display 18.

Next, the mount data displayed on the display screen is input using the mouse 20 or the like at the four corner points (four points indicated by the register marks) of the plate making frame. Based on the coordinates of these four points, the angle of the plate making frame of the mount data and its center point are calculated by the central processing unit (CPU) 17 (f4). Then, the mount angle is automatically corrected (f5). When the plate making frame is tilted with respect to the scanner, the angle of the plate making frame is corrected to 0. The corrected mount data is stored in the storage means 16 again.

Then, the correct position of the mount data corrected based on the calculated center point is determined with respect to the trimming data stored in the layout data storage means 14 (f6). For example, the center point coordinates of the plate making frame after correction are made to coincide with the center point coordinates of the plate making frame of the trimming data, and the other corrected mount data is also corrected again based on the data after the center point matching.

Next, platemaking data is added to each layout area of the mount data, and this is stored in the layout data storage means 14 (f7). Further, the central processing unit (CPU) 1 is based on the mount image data held in the mount data storage means 16 and the layout data stored in the layout data storage means 14.
7 performs layout calculation processing, and the calculation result is output from the image output means 18 to a plate-making film or the like (f
8).

More specifically, a mount is placed on the set surface of the coordinate input means 15 such as a digitizer. Then, the vertical size, the horizontal size, the vertical size, the horizontal size, the cut width, and the like of the plate making frame forming the paper surface are input as numerical values by the keyboard 21. Normally, in plate making, the work is mainly done in plate making size.

Positioning marks called registration marks are drawn on the mount. Therefore, four points on the mount, namely A
(X1, Y1), B (X2, Y2), C (X3, Y
3) and 4 points of D (X4, Y4) are input by a pointing device such as the mouse 20. Then, the origin of the mount is calculated based on the plate-making size that has already been input. When the center point of the plate making frame is S (XS, YS) and the origin of the mount is O (X0, Y0), the relationship between these points is expressed by the following equation. XS = (X1 + X2 + X3 + X4) / 4 ... YS = (Y1 + Y2 + Y3 + Y4) / 4 ... X0 = XS- (actual plate-making lateral size / 2 ) ... Y0 = YS- (actual plate-making vertical size / 2) ...

Next, based on the origin O (X0, Y0) of the mount, a line drawing such as a rectangle drawn on the mount is traced to input coordinates of layout data such as trimming figures.

Next, the mount data will be described. Above

calculate. For example, according to the following formula. θ = acos [(X6-X5)²/ {((X6-X5)²+ (Y6-Y5)²)^{1 / 2} × (X6-X5)}], where X5 ≠ X6.

Next, correction is performed to rotate the image data of the mount based on the value of the tilt angle θ. As a method of correcting the rotation angle, for example, a method such as affine transformation can be applied. The corrected image data is written in the mount storage means 16 again. The coordinates of the four points after rotation angle correction are E '(X5
a, Y5a), F '(X6a, Y6a), G' (X7
a, Y7a) and H '(X8a, Y8a), the coordinates I (XI, YI) of the center point of the mount are given by the above relational expressions.
And the origin J (XJ, YJ) is determined.

As a result, the mount data is displayed on the display screen, and the origin O (X0, Y0) of the layout data is aligned (matched) with the mount origin J (XJ, YJ).
As a result, a figure such as a trimming frame is displayed at an appropriate position.

[0034]

As described above, according to the present invention, complicated and long-time skilled work is unnecessary in inputting mount data. The workability of inputting mount data can be improved. In addition, it is possible to surely correct the deviation of the mount set. It is possible to suppress the positional deviation due to the expansion and contraction of the mount as long as it does not cause any problem as an output. Further, it is possible to reduce the occupation time of the total scanner device for the mount input work.
