Description

[Detailed description of the invention] [Industrial application field] This invention relates to a manuscript image editing device that edits images in a specific area of a manuscript, and is particularly useful for editing images on a single sheet of manuscript. This invention relates to improvement of an optimal manuscript image editing device.

[Prior Art] Generally, for a document 1 containing a certain figure, map, graph, etc., a specific area A of the document 1 is surrounded by a thick line, or a specific area B is hatched or shaded, as shown in FIG. There are cases where a pattern such as the above is added or a specific area C is colored, and there is a desire to automatically perform various editing operations on the original document 1.

Conventionally, this type of document image editing apparatus has an installation board 2a on which a document 1 is placed, as shown in FIG. A coordinate reading device 2 such as a digitizer for reading, a computer 4 that performs image editing control according to the coordinate information read by the coordinate reading device 2 and editing mode information selected by operating an appropriate editing mode switch, and a document. An X-Y plotter or the like has an installation board 5a on which a document 1' equivalent to 1 is installed, and performs image editing on the document 1' on this installation board 5a based on image editing control information from the computer 4. An image writing device 5 is used.

[Problems to be solved by the invention] However, in such a conventional manuscript image editing device, the editing coordinate position is read from one manuscript 1 by the coordinate reading device 2, and the editing coordinate position corresponding to the read editing coordinate position is read. Since the image writing device 5 edits the original document area, two identical documents 1 and 1' are essential for the coordinate reading means 2 and the image writing device 5. In this case,
Document 1 based on the coordinates read by the coordinate reading device 2
In order to match the image editing area of the document 1' with the image editing area of the document 1' in the image writing device 5, the set positions of the document 1, 1' on the installation boards 2a, 5a of both devices 2, 5 must be aligned. However, at this time, copy one of the originals 1' onto tracing paper or the like, and set the original setting position corresponding to the original setting position on the coordinate reading device 2 side on the installation board 5a of the image writing device 5. Since it is necessary to set the document 1' to the set document setting position and align the document 1' with the set document setting position, there is a problem that positioning the document 1' in the image writing device 5 becomes troublesome.

In order to solve such problems, conventionally, a process is carried out to correct the displacement between the set position of the document 1 on the coordinate reading device 2 side and the set position of the document 1' on the image writing device 5 side. It is conceivable to give the program to the computer 4, but in this case, the entire device consists of three independent device groups 2,
4 and 5, and the overall processing program of the computer 4 becomes complicated, resulting in a problem that the cost of the device further increases.

In addition, as a manuscript image editing device different from the conventional one,
A device that reads a document in advance with a document image reading device such as a CCD or a contact image sensor, performs the desired image editing on a computer display, and then outputs the edited document image with an image writing device such as a full-color plotter or printer. However, these devices require extremely high equipment costs, and even when performing image editing to add pictures or patterns only to the necessary parts of the manuscript, the entire manuscript must be recreated. , a problem arises in that image editing takes too much time.

[Means for Solving the Problems] This invention was developed with a focus on the above-mentioned problems, and allows for accurate partial image editing of manuscripts in a short time while reducing equipment costs. The present invention provides a document image editing device that is capable of editing images.

In other words, this invention includes a document placement board on which a document is positioned and installed, a coordinate reading means for reading the coordinates of an image editing area in order to identify the image editing area of the document placed on the document placement board, and An image writing means writes an image in a predetermined editing mode in the image editing area of the manuscript placed on the board, and editing control information is generated based on the coordinate information read by the coordinate reading means and the editing mode information from the editing mode selection means. This is a document image editing apparatus comprising: an editing control means for creating an image and driving and controlling the image writing means according to the editing control information.

In such technical means, it goes without saying that the design of the document placement board can be changed as appropriate, as long as it can hold the document in a predetermined position, including an electrostatic adsorption method.

In addition, the coordinate reading means described above may be designed with appropriate design changes as long as it can read the coordinates of any position on the document on the document placement board, or may be one that applies an electromagnetic dielectric type digitizer or one that specifies the coordinate position. The coordinate indicating member may be appropriately moved in accordance with the coordinate specifying information from the means, and a coordinate indicating member may be appropriately selected such that coordinates can be input at a predetermined position.

Further, as the image writing means, an X-Y plotter, a printer, etc. may be used as appropriate as long as it can write an edited image based on the editing control information.

Furthermore, the editing control means determines an image editing area from the coordinate information from the coordinate reading means, determines what kind of editing is to be performed according to various editing mode information from the editing mode selection means, and As long as it is possible to create editing control information according to the editing mode corresponding to the image editing area, the design may be changed as appropriate, such as by using a microcomputer system. In this case, the image editing area may be determined based on coordinate values that are sequentially input in response to on/off operations of a coordinate input switch from a coordinate reading device; The image editing area may be determined based on coordinate values that are automatically sampled at appropriate intervals in the coordinate reading device. Further, the editing modes include a frame enclosing mode, a hatching mode, a hatching mode, a solid line mode, a dotted line mode, a coloring mode, and the like.

[Operation] According to the technical means as described above, the coordinate reading means reads the coordinates for specifying the image editing area from the original placed on the original placing board, and sends the read coordinate information to the editing control means. input.

The editing control means creates editing control information based on the coordinate information and editing mode information from the editing mode selection means, and controls the image writing means.

Then, the image writing means performs predetermined image editing on the image editing area of the original on the original placing board.

[Example] This invention will be described in detail below based on the example shown in the attached drawings.

Next, the operation of the document image editing apparatus according to this embodiment will be explained with reference to the flowchart shown in FIG.

First, when using this document image editing device, it is necessary to position and install the document 1 on the tablet 10 as shown in FIG. 9a, and in this case, the main screen shown in FIG. Turn on the switch 56 to turn on the device power (step 1, hereinafter abbreviated as ST1), and in this state, position and place the document 1 at a predetermined position on the tablet 10 (ST2). Electrostatic adsorption switch 1
8 (ST3).
At this time, the electrode 15 in the electrostatic adsorption plate layer 12,
The document 1 is positioned and fixed on the tablet 10 by the electrostatic force between the tablets 16 and 16.

Next, as shown in FIG. 9b, the image editing area S
To perform a coordinate input operation to specify the
As shown in FIG. 8, the work start switch 51 is turned on (ST4), and in this state, the cursor 25 is moved to an appropriate position (ST5), and as shown in FIG. When the coordinate input switch 28 is placed at the starting point P1, turn on the coordinate input switch 28 (ST6, 7), and thereafter perform the same operation for each coordinate input point Pi in sequence (ST8), and then perform the operation at the coordinate input end point Pn. When this is completed, the input end switch 29 may be turned on (ST9). still,
If continuous coordinate input mode is adopted, coordinates can be automatically input at fixed time intervals by continuing to press the coordinate input switch 28. In this case, it is not necessary to stop moving the cursor 25 every time, making the coordinate input work easier. At this stage, all the coordinates necessary to specify the image editing area S on the document 1 are stored in the RAM 64 of the control unit 62, and the control unit 62 performs linear approximation between each coordinate. Thus, the image editing area S can be understood.

Thereafter, as shown in ST10 of FIG. 8, by turning on the appropriate editing mode selection switch 52, the control section 62 will grasp the editing mode to be executed on the image editing area S. , At this stage, a predetermined editing control signal to be given to the image writing means 30 is created.

At this stage, if an edited image is to be written on the original 1, the writing start switch 53 is turned on as shown in AT11 in FIG.
Appropriate control signals are sent to the X pulse motor 34, Y pulse motor 38, and electromagnetic actuator 43 to start the image writing operation (ST12). At this time, as shown in FIG. 9c, the pen cartridge 31 moves appropriately in the X-axis direction and the Y-axis direction to move to the image editing area S, and lowers the writing pen 41 in the image editing area S. Then, an edited image is written in a predetermined editing mode, for example, hatching mode. Then, when the control unit 62 determines that the image writing operation is completed,
After controlling each driving section of the image writing means 30 to raise the writing pen 41, the pen cartridge 31 is returned to the initial position (ST13, ST14).

Thereafter, when the control unit 62 recognizes that there is another image editing area on the document 1, the control unit 62 performs the above-mentioned process.
Processing after ST5 is performed sequentially (ST15), and document 1

Further, as shown in FIG. 13, the coordinate reading means 20, unlike the first embodiment, has a coordinate position indicator (hereinafter referred to as a mouse) 71 for variably setting the coordinate position to be input. is a rotation detection body 72 for detecting the rotation direction and rotation amount.
is incorporated, and a detection signal from this rotation detection body 72 is input to the control section 62 via an input interface 61 as shown in FIG. In this case, the control section 62 includes a coordinate position movement function section 75, and this coordinate position movement function section 75 moves the pen cartridge 31 into a non-writing state ( A movement stroke for moving the writing pen 41 in a raised state (holding state) is set, and each driving section of the image writing means is controlled in accordance with the set control signal. And the mouse 71
is provided with a coordinate input switch 73 for inputting the coordinate position indicated by the tip of the writing pen 41, and an input end switch 74 which is turned on when the coordinate input operation is completed.

Further, the control section 62 (see FIG. 7) constituting the editing control means 60 drives and controls the coordinate reading means 20 and the image writing means 30 according to the flowchart shown in FIG. There is.

Note that the same constituent parts as in the first embodiment are given the same reference numerals as in the first embodiment, and detailed explanation thereof will be omitted here.

Therefore, according to the document image editing apparatus according to this embodiment, when positioning and setting the document 1 on the tablet 10, as in the first embodiment, the document image editing apparatus shown in FIG.
As shown in ST1 to ST3, after turning on the device power, the document 1 is placed on the tablet 10, and then the electrostatic adsorption switch 18 is turned on.

After this, when inputting the coordinates necessary to specify the image editing area on the document 1, first turn on the work start switch 51 (ST4), and then, unlike in the first embodiment, move the mouse 71 as appropriate. Operate to move the writing pen 41 of the image writing means 30 in a non-writing state (ST5), and if the indicated position of the writing pen 41 is the coordinate position to be input, turn on the coordinate input switch 73. (ST6,7). Then, the same operation is repeated in sequence for each coordinate input point (ST8), and when all the coordinate input operations are completed, the input end switch 74 is turned on (ST9), and the control unit 62 All the coordinate values are recognized as those for specifying the image editing area.

Thereafter, as shown in ST10 and ST11 in FIG. 14, by operating the editing mode selection switch 52 and then operating the write start switch 53, a predetermined image writing operation is performed.

In such an operation process, the coordinate reading operation becomes indirect, so the coordinate reading operation becomes a little more troublesome than in the first embodiment. Since it is not necessary to provide it, the manufacturing cost of the tablet 10 can be reduced accordingly.

[Effects of the invention] As explained above, according to the manuscript image editing device according to this invention, when editing a part of a manuscript, image editing can be performed without combining three devices, and , I was able to edit only the necessary parts of the manuscript without having to re-create the entire manuscript.
Not only can the device configuration be simplified and the device itself be provided at low cost, but also the time required to edit images of a document can be shortened.

In addition, according to this idea, the image editing area is extracted from a single document and the desired image editing is performed on the same document, so two documents can be aligned on different installation boards. This eliminates the need for tedious work, which makes it easier to set the original, and because there is no misalignment of the original at the set position, it is possible to maintain good image editing accuracy. Since there is no need to incorporate a program for document alignment correction into the editing control means, it is also possible to effectively prevent the editing control means from becoming unnecessarily complicated.
