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 scanner's ability to simultaneously process 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 relative to the original before exposing it when exposing the film on the exposure drum after scanning the original. This is because they may not have it.

It is technically possible to perform angular rotation in the computer that processes the information for page collection, and some have adopted it, but the capacity of the computer itself has increased, the processing time has increased, or the resolution required for the rotation process has been considered. Since problems such as deterioration occur, there are some images that are disadvantageous 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 requires information that allows determining the position of the trimming frame and outputting the output image to a predetermined position within the trimming 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 the original image at the position of .

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 manuscript image is determined arbitrarily to some extent, while 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 manuscript image 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, there is also a method in which the position of the image of the document within the trimming frame is visually confirmed by displaying it on a monitor TV, and the layout position is determined by 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 an image 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, a document is attached to the document drum of a layout scanner at a predetermined angle and a color separated image is output according to a predetermined layout.
They are described in JP-A-55-21033, JP-A-55-3313, JP-A-55-50235, JP-A-55-64238, etc., and may be selected as appropriate.

Separately, in the present invention, the positional information of the reference point in the layout image on the layout designation sheet and the positional information of the trimming frame are obtained in advance.

FIG. 3 is an explanatory diagram of an example of the position information,
A trimming frame 2 surrounded by points B, C, D, and E and a layout image 3 are drawn on the layout designation sheet 1.

The positional information of the trimming frame 2 is determined using the coordinate origin A on the layout sheet as a reference, and this can be easily determined using a digitizer table, a ruler, or the like. If the trimming frame 2 is a rectangle like the example shown in Fig. 3, specify its shape by specifying three points such as points B, C, and D, or by specifying two points such as points B and E. can be done, and appropriate means can be adopted.

Furthermore, positional information of an arbitrary reference point P in the layout image 3 applied to the layout sheet 1 is obtained. The reference point P is an image that can be easily specified in the layout image, for example, a button on a person's clothes, or a point of intersection of two electric wires in a landscape.

In the present invention, as shown in FIG. 4, the positional information of the reference point P' and the input start point Q of the image 38 in the document 31 is also obtained. In this case, it goes without saying that the input starting point Q is on or outside the required picture pattern, ie, the trimming frame. As the reference point P' in the image in the original document, a location corresponding to the reference point P in the layout designation sheet is adopted.

Positional information on these documents can also be easily obtained using a digitizer table, ruler, etc., as described above.

The output position of the color separated image is controlled based on the position information on the layout designation sheet and the position information on the document, which are obtained as described above.

Control of the output position is performed as follows.

The original 31 is attached to the original drum of the layout scanner at a predetermined angle, and is input from the input starting point Q and stored in the storage device. In this case, it is possible to know at which address in the storage device the pixels of the input starting point Q and the reference point P' in the image of the original are stored based on these positional information.

On the other hand, which point on the output film the position of the reference point P in the layout image on the layout designation sheet and the position of the trimming frame 2 correspond to is determined based on the positional information of these points on the layout designation sheet. be done. As shown in FIG. 5, the point FP on the output film 34 of the reference point P and the trimming frame 2' on the output film 34 of the trimming frame 2 on the designated layout sheet are determined based on the position information on the designated layout sheet. be done.

On the other hand, the pixel at the point corresponding to the reference point P' in the document must be output to the point FP on the output film. By determining the output position of the pixel at the point corresponding to the reference point P' on the output film, the pixel at the point corresponding to the input start point Q corresponds to the position of point Q' in the output film 34. It is known that this is possible. However, since the position of point Q' is outside the trimming frame 2' to be output, no actual output is performed and the point
A color separated image is output only inside the trimming frame 2' surrounded by B', C', D', and E'.

In this way, the output position of the color separated image is controlled, and the color separated image is output at a predetermined layout position.

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. Since the necessary layout processing is completed, it is no longer necessary to perform layout processing on the monitor television as in the past, and the operating efficiency is improved.
