Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to a layout scanner system used when making a plate for originals such as color photographs, in particular, for enlarging, reducing, rotating, etc. The present invention relates to a scanner system that is most suitable for use when performing image processing or reusing or reusing images by changing cropping.

[Prior Art] Currently, in the field of plate making, layout scanner systems have been developed and put into practical use when making plates of manuscripts such as color photographs. This layout scanner system has an editing function that can output one or more images in a desired layout on one film. This type of layout scanner system is sold by many manufacturers.
This is an extremely innovative plate-making system.

Its common uses include, for example, special processing such as erasing acne, wrinkles, etc. from human images, and plate making (block collection). Additionally, although color photo printing is generally treated as a temporary process, catalogs, pamphlets, leaflets, etc.
Apply image processing such as reduction and rotation, or reuse by changing cropping.

Often reused. In general, the former is often referred to as a collection work, and the latter is referred to as a database-based prepress work.

[Problem to be solved by the invention] By the way, commonly used (appropriated, reused) color photographs, etc. can be saved as a database on external recording media such as magnetic tapes and magnetic disks and reused. , During this reuse (during database operation), processing of changing the image size (enlarging/reducing the image, etc.) is generally involved.

In other words, it is rare that the state of the image registered in the database and the current desired layout are the same, so it is necessary to enlarge or enlarge the image registered in the database.
Reduction and rotation processing is required. Therefore, in order to perform such database work, the layout specified at the time of registration in the database and the current desired layout are generally compared, and processing such as enlargement, reduction, rotation, etc. is performed, but usually only the layout specified paper is used. Since the magnifications and tilt angles provided by the customer are different and there is no standard, it is extremely difficult to calculate the information on enlargement, reduction, or rotation for scaling or rotation processing. This was time consuming and resulted in the problem that database work could not be performed efficiently. By solving these problems, it can be said that the layout scanner system can become a truly effective system.

The present invention has been made to solve the above-mentioned problems, and includes information on enlargement, reduction, or rotation for scaling or rotation processing when reusing image information of originals registered as a database. It is an object of the present invention to provide a scanner system which can efficiently and easily perform the work of calculating , and thereby can perform database work extremely efficiently.

[Means for Solving the Problem] In order to achieve the above object, the present invention includes an image input means for inputting an image of a document, color-separating the image information, and outputting the image information; A storage means for registering image information as a database at an arbitrary magnification (or tilt angle), a magnification angle determining means for measuring the magnification and tilt angle of a hard copy of a manuscript with respect to a specified layout sheet, and an arbitrary magnification (or tilt angle). A function to output the image information registered in the output means as a hard copy at a desired magnification (or tilt angle), and to output the magnification information (or tilt angle) obtained by the magnification angle output means from the specified layout paper using the hard copy. ), 1 image registration magnification information, and hard copy output magnification information. The image processing means has a function of performing enlargement/reduction processing (or rotation processing) on the registered image information in consideration of the output inclination angle) and outputting it to the output target.

[Function] Therefore, in the scanner system of the present invention, image information registered at an arbitrary magnification (or tilt angle) is created as a hard copy at a desired magnification (or tilt angle), and this hard copy is used to create a hard copy. The output magnification (or output tilt angle) of the registered image information is automatically calculated based on the magnification information (or tilt angle) obtained from the specified layout paper, the image registration magnification information, and the hard copy output magnification information. By doing so, it is possible to extremely efficiently and easily perform the work of calculating enlargement/reduction or rotation information for scaling or rotation processing when reusing the image information of the manuscript registered as a database. It becomes possible.

[Example] In the present invention, the magnification information (or tilt angle information) of the currently desired layout is measured without a document, and the image registration magnification information (or tilt angle information) of the image information registered in the database is measured. ), create a hard copy (along with a reference line) of the image information registered in the database at a predetermined magnification (or tilt angle) at the desired magnification (or tilt angle), and use this hard copy as the original. Instead, magnification information (or tilt angle information) is measured by a magnification angle determining means.

Here, the magnification is the magnification for the size of the hard copy. Therefore, if the magnifications of the hard copy and the registered image information are different, it is necessary to calculate the magnification by adding the difference in magnification between the hard copy and the registered image information to the magnification determined by the magnification angle determining means. The obtained magnification becomes a parameter for enlarging/reducing the image information registered in the database to the currently desired image size. Moreover, the inclination angle is an angle with respect to the reference line. Therefore, if the inclination angles of the hard copy and the registered image information are different, it is necessary to calculate the inclination angle by adding the difference between the inclination angles of the hard copy and the registered image information to the inclination angle determined by the magnification angle determining means. The tilt angle obtained in this manner becomes a parameter for rotating the image information registered in the database into the currently desired image.

An embodiment of the present invention based on the above concept will be described below with reference to the drawings.

It consists of a computer 11, a color hard copy machine 12 and an output device 13 as output means.

Here, the color scanner 1 inputs an image of a document or a color photograph, and converts this image information into Y (yellow) 9M (
The image is separated into four colors: magenta), C (cyan), and BK (black) and output. Also, magnetic disk 2
is for storing image information output from the color scanner 1. On the other hand, the digitizer 3 reads positional information such as plate making size and mask information shown on the layout designation sheet or the master copy, and displays this on the graphic display 4. Further, the magnetic disk 5 or the floppy disk 6 is used to store device information constituted by the digitizer 3. Further, the magnification angle determining device 7 measures the magnification and tilt angle of the finished original or its hard copy, and stores this on the floppy disk 8. Furthermore, the optical disc 10 registers image information outputted from the color scanner 1 at an arbitrary magnification m as a database.

On the other hand, the computer 11 reads the image information and position information stored on the magnetic disk 2 and the magnetic disk 5, respectively, and displays this information on a color display based on the magnification and tilt angle information stored on the floppy disk 8. 9, the hard copy machine 12 converts image information of a color photograph registered on the optical disk 10 at a desired magnification m into a hard copy at a desired magnification n.

It has a function of calculating the output magnification A of the image information, and a function of performing enlargement/reduction processing on the registered image information in consideration of the calculated output magnification A of the registered image information and outputting it to the output device 13. The hard copy machine 12 also stores information processed by the computer 11 (

This is to output the plate collection calculation result information) to a plate-making film.

Next, in the layout scanner system configured as described above, the image information of the color photograph separated into colors by the color scanner 1 is once stored on the magnetic disk 2. Further, positional information such as the plate making size and mask information shown on the layout designation sheet or the master plate is read by an appropriate means such as the digitizer 3 and stored on the magnetic disk 5 or floppy disk 6, and is also stored on the graphic disk. Displayed on Spray 4. Furthermore, the magnification and inclination angle of the original in the finished state are measured by the magnification angle measuring device 7 and stored on the floppy disk 8. Furthermore, the image information output from the color scanner 1 is, in principle, unedited, tone corrected, etc., and then stored on the optical disk 10 at the magnification m at the time of disassembly as a database.

On the other hand, in the computer 11, the image information and position information stored in the magnetic disk 2 and the magnetic disk 5 are respectively read out, and this information is read out from the floppy disk 8.
The image is displayed on the color display 9 based on the magnification and tilt angle information stored in the . In this case, the computer 111 adjusts the relative position between the line indicating the mask displayed on the color display 9 and the color-separated image information, so that the color-separated image information is automatically placed in a predetermined position. image information and position information are combined. By performing such image processing on each color-separated image, the positions of all images to be output on -sheets of film are determined, and output from the output device 13 onto a plate-making film.

Next, when reusing the image information of the color photo registered as a database on the optical disk 10 (database operation), the computer 11 reuses the image information of the color photo registered on the optical disk 10 at an arbitrary magnification m. , processing to output at a desired magnification n is performed, and information on the processing results is output as a hard copy from the hard copy machine 12. In this case, if the image information of the color photo registered on the optical disc 10 is very large, it is reduced and output as a hard copy.
When the image information of a color photograph registered on the optical disc 10 is very small, it is enlarged and output as a hard copy.

Note that the image information of the color photograph registered on the optical disc 10 may be output as a color hard copy in its original size.

Next, in the computer 11, using this output hard copy, magnification information O is obtained from the layout designation paper by the magnification angle determining device 7, and this magnification information 0 and magnification information m at the time of 2 image registration, and the hard copy Based on the magnification information n at the time of output, the magnification A at the time of output of the registered image information is calculated according to the formula A=(n/m)·0. For example, m-200 (%)
, n-100(%), 0-200(%), the output magnification A of the registered image information is calculated to be A-(100/200).200-100(%).

Then, the computer 11 performs enlargement/reduction processing on the registered image information in consideration of the calculated output magnification A of the registered image information (in this example, it is A-100 (%), so the enlargement processing is also performed. (No reduction processing is applied.) Then, in the computer 11, information on the processing results of the image is stored in the magnetic disk 2, and then the laid-out image is outputted from the output device 13 onto a plate-making film.
