Description

DETAILED DESCRIPTION OF THE INVENTION Recently, color scanners have been known that have a so-called editing function, that is, a full-page collection function, which performs color separation and final layout at the same time.

Color scanners equipped with such editing functions are generally called layout scanners, and after inputting the original image, the scanner outputs the image by exposing it to the film at the specified position and with specified trimming. Can be done.

In order to attach a document to such a layout scanner, it is necessary to make the document have a predetermined angle with respect to the base line of the document drum of the scanner in accordance with the final layout. This is due to the following reasons.

That is, as shown in FIG. 1, when the document 31 is attached to the document drum 30 immediately with respect to the straight line 32 of the document drum, the film 3 attached to the exposure drum 33 after being scanned is
The image 35 exposed at 4 also follows the straight line 36 of the exposure drum.
The result is a direct image.

Therefore, in order to fully utilize the functions of this scanner for simultaneously processing color separation and layout, an image 37 that is oblique to the straight line 36 of the exposure drum is required, as shown in FIG. When the original 31 is attached to the original drum 30, it must be attached obliquely to the straight line 32 of the original drum. This is because the scanner itself has a function that rotates the scanned image at an arbitrary angle with respect to the document before exposing it to light when exposing the filter on the exposure drum after the scanner itself scans the document. This is because there may be cases where it has not been done.

It is technically possible to perform angular rotation in the computer that processes the information for page collection, and some have adopted it, but due to the increase in the capacity of the computer itself, the increase in processing time, or the rotation process. Since problems such as a decrease in resolution occur, there are disadvantages in terms of cost, time, and quality.

Further layout information is required to obtain the final edited output by the layout scanner. This layout information is
Information is needed to determine the position of the cropping frame and to output the output image to a predetermined position within the cropping frame.

Conventionally, in order to obtain this layout information, the trimming frame and the original image are reproduced on a monitor TV, the trimming frame and/or the original image are moved, the trimming frame is placed at a predetermined position, and the trimming frame is placed at a predetermined position within the trimming frame. It was common to obtain layout information by arranging a document image at a position.

The reason for adopting such a method is as follows. In other words, the finished size of the original image is generally larger than the size of the original itself.
The trimming position in the image of the manuscript is determined arbitrarily to some extent, and on the other hand, the trimming position and dimensions in the editing page can be numerically processed from the base point within the page, but the position of the image in the manuscript cannot be numerically processed. This is due to the difficulty of That is, the image of the original is generally smaller than the finished size, and it is difficult to numerically determine the trimming start and end points.

When obtaining layout information using the conventional method described above, it is generally necessary to operate expensive equipment for a long time in order to obtain layout information, which is one of the causes of reduced operating efficiency of the equipment. It's becoming one.

Furthermore, in the conventional method described above, it is also known that the layout position is determined by visually confirming the position of the image of the document within the trimming frame by displaying it on a monitor TV, and then comparing it with the position of the layout image on the layout specified paper. However, the accuracy of this method is not good.

The present invention eliminates the drawbacks of the conventional methods as described above, enables numerical processing of the layout position of images on a document, and also allows data necessary for layout to be obtained accurately and easily without using expensive equipment. The purpose is to improve the operating efficiency of expensive equipment.

The present invention will be explained in more detail below.

In the present invention, an auxiliary piece 2 is attached to the original 1 as shown in FIG. 3, if necessary. If the document 1 has a portion on which a reference point or reference line can be drawn, there is no need to attach this auxiliary piece 2.

However, since it is preferable not to perform any unnecessary processing on the original, the following will explain the case where the auxiliary piece 2 is attached, but the invention is not limited to this, and the reference points and reference lines can be directly attached to the original. It may be administered. Any means can be used to attach the auxiliary piece 2 to the original document 1, and it is easy to use an adhesive tape 50 such as cellophane adhesive tape as shown in FIG.

An appropriate position for attaching the auxiliary piece 2 may be selected in consideration of the output image.

The original 1 with the auxiliary piece 2 attached is attached to the transparent plate 3 as shown in FIG. This attachment means can also be carried out extremely easily by using adhesive tape such as cellophane adhesive tape.

The transparent plate 3 to which the original 1 is attached in this way is used to hold the original 1 as necessary for the purpose of protecting the original 1, preventing the original 1 from warping, and for other purposes.
A transparent plate 4 may be further stacked with the transparent plate 4 sandwiched therebetween.

The transparent plates 3 and 4 with the originals 1 attached thereto are loaded onto an original shelf 5 of a projection apparatus as shown in FIG. The projection device shown in FIG. 4 is an explanatory diagram of an example of the device used in the present invention, and includes a light source, a document rack 5, a projection lens 8, and a projection plate 9 arranged in this order. In the figure, the light source is covered by a cover 7 so as not to dazzle the operator.

When the transparent plate 3 with the original 1 attached thereto is loaded onto the original shelf 5 as described above, the transparent plate locking portion 6,
6' is provided.

Further, an arbitrary point on the document 1 or the auxiliary piece 2 is set as the input starting point P. (The position of P may be a single point on the document, but for simplicity, we will explain the case where it is placed on the auxiliary piece.) In the present invention, the transparent plate 3 to which the document 1 is attached as described above is explained. Load the manuscript onto the document rack 5 and display it on the projection plate 9.
Project the image of the original onto it.

The light source, document rack 5, and projection lens 8 can be moved together in the direction of the projection plate 9, and the projection lens can also be moved independently in the direction of the projection plate 9. This allows adjustment of projection magnification and focus.

On the other hand, a layout designation sheet 20 is placed on the projection plate 9,
The projection magnification and the position of the layout designation paper are adjusted so that the layout image 21 applied to the layout designation paper 20 matches the projected image of the original.

In this state, the finished magnification of the original is measured to obtain magnification information. Since an automatic magnification measuring device that can automatically measure magnification is known, magnification information can be easily obtained by employing this device.

13 in Fig. 4 is this automatic magnification measuring device,
The magnification is automatically displayed on this device. Alternatively, the magnification information may be obtained separately by any other arbitrary means.

In the present invention, the positional information of the projected image P' of the input starting point P on the layout designation sheet is obtained in a state where the projected image and the layout image match (see FIG. 5). Note that the positional information of the trimming frames A, B, C, and D on the layout designation sheet 20 is obtained in advance.

The positional information of the original input starting point P on the designated layout sheet is determined as the positional information of the projected image P' as described above.

The above position information can be obtained extremely easily by using an automatic position reading device such as an XY digitizer table.

When obtaining position information using an XY digitizer, the position information can be obtained by moving the cursor 17 to the location where the position should be measured.

The position information, magnification information, and position information of the trimming frame on the layout designated paper of the input starting point P on the document obtained in this way are used to control the input to the layout scanner of the document and the output from the layout scanner, which will be described later. used.

As already mentioned, it is convenient if the original is attached at a predetermined angle beforehand to the original drum, since there is no need to rotate the input image information.

Means for attaching a document to a document drum at a predetermined angle are disclosed in Japanese Patent Laid-Open Nos. 55-21033 and 1983
-3313 Publication, JP-A-55-50235, JP-A-Sho
It is described in Publication No. 55-64238, etc., and may be selected as appropriate. By the way, the registration mark marked on the layout designation sheet is often used as a coordinate reference for plate making, so an example of using it to create a reference line for attaching to the document drum is as follows. Become. Registration marks 15, 15 or 16, 16 facing each other are made on the layout designation paper. When the projected image and the layout image match, the facing registration marks 15, 15 or 1
The angle between the straight line obtained by connecting the points 6 and 16 and the transparent plate locking portion 6 or 6' is determined in advance.

Next, the transparent plate 3 is removed from the document shelf 5, and with the document 1 still attached, the angle between the side that was in close contact with the transparent plate locking portion 6 or 6' and a straight line that is parallel or perpendicular to the plate is determined as described above. A reference line 43 is drawn on the auxiliary piece 2 so as to form an angle between the straight line obtained by connecting the facing register marks obtained in step 1 and the transparent plate locking portion. Any means can be used to determine the angle, and any known means may be used as appropriate, but it is convenient to use a universal ruler 10, generally referred to as the trade name Drafter, as shown in FIG.

To draw the reference line 43 on the auxiliary piece 2, first find the angle using a universal ruler, and also make sure that the side of the transparent plate that was in contact with the document locking portions 6, 6' is
Transparent plate locking part 1 so that it is parallel or perpendicular to 6'
It can be easily applied by placing it on a transparent plate mounting table 18 having a diameter of 1, 11', 11'' and using the universal ruler 10.

The upper surface of the transparent plate mounting table 18 is a light table 12
This makes it easy and convenient to work with.

As already explained with reference to FIGS. 1 and 2, this reference line 43 is used as a reference for determining how much the original should be tilted with respect to the straight line of the original drum when the original is mounted on the original drum. The document is attached to the document drum so that the reference line 43 is parallel or perpendicular to the straight line of the document drum. Whether the reference line 43 is parallel to or perpendicular to the straight line of the document drum depends on the required layout information, and is determined as appropriate.

After the document 1 is mounted on the document drum in this way, the document image is input to the layout scanner and output by the layout scanner based on the position information and magnification information of the input start point P on the document that has been found on the layout designated paper. Control the output position of the image.

Furthermore, by using the input cropping position information, it is possible to determine the cropping of the output image.

Control of input and output of the layout scanner is performed as follows.

First, after the original is attached to the original drum, input is started from the input starting point P, and image information is stored in the storage device. In this case, the input image is wider than the required cropping area. The stored image information is called up and displayed on a monitor television, and after undergoing necessary processing such as checking the layout and correcting the tone, it is stored again in the storage device.

The image information that has undergone the necessary processing and is stored is
The output position is controlled based on the position information of the input start point P on the layout designation paper, and the output is output by the output scanner.

Output control is performed as follows. First, the coordinate system X'-Y' on the exposure drum is set, and the film 34 mounted on the exposure drum is placed in that coordinate system.
The position is controlled by X'-Y' (see Figure 6). This X'-Y' coordinate system corresponds to the X-Y coordinate system of the layout specification sheet. For example, the X' axis is in the axial direction of the exposure drum, and the Y' axis is in the circumferential direction of the exposure drum. Set.

Since the positional information of the input starting point P on the original document on the designated layout paper is obtained in advance as the positional information of the projected image P', it is stored in the first storage location of the inputted and stored image information. It becomes possible to make the image information corresponding to the point (PF) in the X'-Y' coordinate system. Actually, since this information is outside the trimming area, no output is performed in this area. The actual output is based on the position information of trimming frames A, B, C, and D, and the corresponding trimming frames in the X'-Y' coordinate system.
An arithmetic unit determines whether or not it is within the areas A', B', C', and D', and outputs it at the necessary position with the necessary trimming.

As described above, according to the present invention, output according to the final finished layout can be obtained extremely easily using a layout scanner.

Furthermore, according to the present invention, the output position and trimming position of an output image can be easily numerically processed without using an expensive layout scanner, and the operating efficiency of the expensive layout scanner can be improved.

In other words, since the trimming information and layout information are obtained in advance separately from the layout scanner, the layout scanner only needs to automatically perform arithmetic processing according to the predetermined values. , the necessary layout processing is completed, and there is no need to perform layout processing on the monitor television as in the past, improving operating efficiency.
