Abstract

PURPOSE:To complete the assigned input of desired coordinate information with fewer operations by computing arbitrary area information from already set area information. CONSTITUTION:A CPU circuit section 24 converts and computes the coordinate information of the arbitrary area assigned in accordance with the conversion mode assigned by this circuit section and the conversion coordinate information assigned from an editor 26 so that the area under the assignment can be discretely corrected and set in the desired graphic area when the mode to convert the arbitrary area regulated by the coordinate information assigned from the editor 26 to the prescribed graphic area is assigned by a key for assigning the prescribed area on a document or copying paper after the coordinate information assignment. The assigned input of the desired coordinate information is completed with the fewer operations in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying device that is capable of image editing, and more particularly to a copying device that is capable of inputting coordinate information necessary for image editing.

2. Description of the Related Art Conventionally, this type of copying apparatus has become increasingly multi-functional and is configured to easily perform a variety of image editing based on various image editing modes.

For example, trimming copying processing such as copying only images within a set area, mask copying processing such as copying only images outside a set area, etc. are performed.

In order to perform such a copying process, a desired area, for example, two or more points, is specified and inputted using a coordinate information input device such as an editor connected to the copying machine, and then the coordinate information is created based on the specified coordinate information. By controlling the drive of the eraser means (consisting of a semiconductor laser or the like) in parallel with reading the document, an edited image obtained by editing a desired document image can be obtained.

[Problem to be Solved by the Invention 1] However, even if the resolution of the coordinate specification of the editor is highly accurate, there may be slight discrepancies between the input of coordinate information on the editor and the document setting position, or obvious setting mistakes.
In many cases, it is not possible to obtain a desired document corresponding to a designated area.

Therefore, in order to obtain a desired image, it is necessary to determine positional deviations and the like from the output edited image and correct the set coordinate information.

In this case, in order to correct the coordinate information, the number of coordinate points to be corrected increases according to the number of set coordinate points. In other words, when editing an image with three area information memorized, in order to correct the area coordinate information, it is necessary to re-enter the coordinate information for all areas, and specify the area using diagonal coordinates. In a copying apparatus that performs three area corrections, coordinate designation processing for six points is required, which increases the operational burden of coordinate respecification processing and hinders desired image editing processing efficiency.

In addition, in order to correct the position of the original on the document table, it is also possible to correct the position of the document on the document table by correcting the document placement position on the document table by the operator's batch amount. In order to make corrections, it is necessary to accurately grasp the positional relationship between the original and the output image, which poses the problem of causing a considerable number of copy mistakes before obtaining the desired image.

Also, when making corrections, if the coordinate information before correction is significantly changed, for example, moving the area being set to the desired position,
Even if there is a request to change the size or rotate the area that is being set, it is necessary to start over from the beginning with the document instruction operation, resulting in problems such as extremely low operability.

The present invention has been made to solve the above problems, and provides a copying apparatus that can complete the input of desired coordinate information designation with a small number of operations by calculating arbitrary area information from already set area information. The purpose is to

Next, determine whether to confirm the corrected coordinate values,
In other words, it is determined whether the OK key Ok has been pressed (9), and if NO, the process returns to step (1), and if YES, the coordinate values of the area are determined based on the set corrected X coordinate value X and corrected Y coordinate value Y. Modify and change 10) and return.

In addition, in the above embodiment, the set area is changed to 1 after correction.
The case has been described in which the area being specified is moved and corrected by specifying a point instruction on the editor 103, but it is also possible to specify a single point instruction on the editor 103 after copying a set area or an area that has already been registered. By doing so, it is also possible to perform area copying.

Next, a case will be described with reference to FIG. 10, in which an area having the same shape as the designated area is set in other parts.

FIG. 10 is a schematic diagram showing an example of an area copy instruction message displayed on the display unit 319 shown in FIG.
The display state changes from (a) to (d).

If the direction designation key 307d is pressed while the message 412 is displayed as shown in display state (d), or if one or more areas have already been designated, or if one or more areas have already been designated,
When the key 331 is pressed with more than one area specified, a message 409 shown in display state (a) is displayed.

Here, direction designation keys 307u, 307d, 3071 .
When "Area Copy" is selected by operating 307r and the confirmation key 307ok is further pressed, the display section 319
The display state becomes (b), and message 410 is displayed. Here, for example, if you select "Area 1" and press the OK key 307, the display state of the display section 319 changes to (
c), and the location of area 1 and message 411 are displayed.

Here, when one predetermined point is specified on the editor 103, area 3 (area 2 has already been specified ) are calculated, and the display state (
As shown in d), when the message 412 is displayed and the OK key 307 is pressed, the area copying process is completed and a new area 3 is set.

Furthermore, in the first embodiment, a case has been described in which the specified area is moved and corrected by specifying a single point after correction on the editor 103.
As shown in FIG. 11, a message 413 is displayed on the display section 319.
is displayed, and the magnification/rotation mode for the set area can be set. In addition, under the set magnification/rotation mode, the magnification index 1201 (No. 12) or by specifying the rotation index 1202 in the rotation angle index, for example, the vertical/horizontal 15 centering on the center of gravity of area 1 can be adjusted.
By calculating the coordinate values for the area rotated by 0% or by 90 degrees clockwise, it is possible to easily generate a rotated or magnified area for the area being set.

[Advantageous Effects of the Invention 1] As explained above, the present invention includes a specifying means for specifying a conversion mode for converting an arbitrary area defined by coordinate information specified by an editor means into a predetermined graphic area, and Since we have provided a calculation means for converting the coordinate information of any area to the coordinate information of the specified graphic area based on the specified conversion mode and the conversion coordinate information specified from the editor, Various correction areas can be easily generated based on the area. Therefore, compared to conventional area correction processing, it is possible to perform area correction and the like in a short time with much fewer operations.
