Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in textile design processing systems.

The textile design processing system converts the pattern drawn by the designer into pattern data, stores it in memory, reproduces this on a color display device, and then corrects, changes, and edits the design according to instructions from the operation panel. This is a highly efficient design processing system designed to process

First, an example of this textile design processing system to which the present invention is applied will be explained with reference to FIG.

The figure shows a schematic configuration of the system.

A pattern drawn by a designer is converted into pattern data by a color drum scanner 2 as an original image 1. This color drum scanner 2 is a device that automatically reads color images.
is attached to a drum (not shown) and rotated to form pattern data including color information of the three primary colors of red, green, and blue or density differences.

The pattern data formed over the entire surface of the original picture 1 is
It is stored on the floppy disk 3 or magnetic tape and is once filed.

Then, the floppy disk 3 or magnetic tape to be subjected to design processing is set in the computer system 4, and the pattern data is temporarily stored in the magnetic disk 5.

At this stage, the data of the original image 1 is stored in the magnetic disk 3 for each stitch, which is the smallest unit of the fabric. Note that address information may be attached to the data of the original image 1, but in this system it is separated and address control is performed by a program.

Next, on the operation console for design processing,
An operation unit 7 including a color display 6 and a tablet for inputting coordinates is arranged, and an input/output control unit 8
It is connected to the computer system 4 via.

The input/output control section 8 includes an image storage section for the color display 6, and can transfer desired pattern data from the magnetic disk 5 to the image storage section in response to a command from the operation section 7. ing.

As described above, the operating section 7 is provided with a tablet for inputting coordinates, and by moving a pen onto the tablet, coordinates on the display screen of the display 6 are specified. That is, a cursor for specifying coordinates is displayed on the display screen of the display 6, and this cursor can be moved to an arbitrary position by the movement of a pen on the tablet.

Furthermore, the operation section 7 is provided with an erase key, a color change key, etc., so that the color of the area indicated by the cursor can be erased or changed.

Therefore, in order to modify the color of a specific location, the user must first move the cursor to the specific location using the tablet, and then operate the color change key. The design and pattern can be modified by moving the cursor and continuously operating the color change key, erase key, etc.

Finally, when the design process is completed, the pattern data is continuously output from the magnetic disk 5 to the pattern paper puncher 8, where it is sent to the pattern paper puncher 8, which is necessary for the operation of the loom.
will be formed.

FIG. 2 shows an external view of the color display 6 and the operation section 7 of the above-mentioned design processing system.
In the same figure, 11 is the cursor, 12 is the tablet, and 13 is the cursor.
1 is a pen, 14 is a color selection switch, and 15 is a function key for making color corrections.

Although the outline of the textile design processing system to which the present invention is applied has been described above, the conventional system had the following drawbacks.

That is, the image storage section provided in the input/output control section 8 only functions as a buffer memory for the color display 6, and its storage capacity is in a one-to-one correspondence with the display screen area of the color display 6. It was hot. Therefore, in order to process a large design in a continuous pattern, it is necessary to replace the stored contents in the image storage section, which puts a heavy burden on the software and causes the screen to be displayed intermittently every time the design is replaced. As a result, there was a drawback that a series of patterns could not be displayed continuously and smoothly.

Therefore, an object of the present invention is to provide a pattern display control device for a textile design processing system, which can continuously display even large-sized patterns and perform design processing smoothly and efficiently. Our goal is to provide the following.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 shows a block diagram of a pattern display control device which is an embodiment of the present invention. Note that this pattern display control device is included in the input/output control section 8 shown in FIG.

In the same figure, a coordinate input section Z and a screen shift key S are provided in the operation section 7 shown in FIGS. It is composed of

The image storage section M functions as a buffer for temporarily storing the display data of the pattern displayed on the color display 6, but its capacity is larger than the storage capacity corresponding to the display screen of the display 6. The contents are transferred from the magnetic disk 5 by operating the operating section 7.

The control unit CT constantly scans the contents of the image storage unit M, converts the data into a video signal, and sends it to the display 6. Note that the scanning area at this time is an area specified by the shift key S. Therefore, the control unit CT moves the specified area of the image storage unit M in accordance with the operation of the shift key S, and scans the storage unit corresponding to the display screen of the display 6 in the moved area.

Further, the cursor position specified by the coordinate input section Z is written as cursor data at the position of the storage section M corresponding to the position.

The image storage unit M, control unit CT, and operation unit 7 are as follows:
The input/output controllers are connected to each other and to the computer system 4 via I/O.

Next, a screen shift key S for shifting a designated area of the image storage unit M, that is, a storage area corresponding to the display screen of the display 6 within the storage unit M;
The relationship of the image storage section M will be explained with reference to FIGS. 4 and 5.

FIG. 4 shows a main block diagram of the pattern display control device, and schematically represents the image storage section M.
Further, FIG. 5 is a flowchart showing the control procedure in the control unit CT when the shift key S is operated.

In FIG. 4, the image storage unit M is arranged in the X-axis direction.
It has a capacity of 1024 points and 240 points in the Y-axis direction.
In addition, the display 6 has 320 points in the X-axis direction and 320 points in the Y-axis direction.
It has a display area of 240 points in the axial direction.

Note that one point corresponds to one stitch when fabricated, and refers to the intersection of the crossing thread and the needle thread.

Since the sizes of the image storage section M and the display 6 are as described above, display data stored in the image storage section M at one time is stored on the display 6.
This corresponds to more than three times the number of patterns that can be displayed at once. Furthermore, in order to continuously change the displayed pattern, it is sufficient to shift the designated area in the image storage section M, that is, the storage area corresponding to the display screen of the display 6, in the X-axis direction. Recognize.

The screen shift key S consists of three keys, namely the □← key, the □→ key, and the □G key. It seems like he is giving instructions to return.

In addition, in the control unit CH, by one operation of the □← key or the □→ key, the designated area is shifted by 8 points in each direction, and scanning is started in the newly shifted area. do. Therefore, the display screen on display 6 can be changed by pressing the □→ key or □←
The symbol moves to the right or left by the number of points multiplied by 8 points.

Now, assuming that area (A) of the image storage unit M shown in FIG. Ru. At this time, the display data stored in areas (B) and (C) is not sent to the display 6.

Assume that the screen shift key S is operated from this state. First, if you press the □→ key once, area (A) will shift eight points to the right while maintaining 320 points x 240 points. Then, each time you press the same key, you move 8 to the right.
Shift by points. Also, if you press the □← key, the area (A) shifts 8 points to the left each time you press the key. Then, if you press the □G key, the specified area
(A) will be unconditionally moved to the left end of the storage section M.

This control procedure is shown in the flowchart of FIG.

As is clear from the flowchart in the figure, steps n ₀ ~
Use n ₃ to determine whether or not the screen shift key S has been operated and its type, and use n ₄ to _{n 6} to change the specified area, that is, add or subtract 8 points to the address of the image storage unit M currently being displayed, or Set it to the origin address.

In this manner, by operating the screen shift key S, the areas (B) and (C) that are not currently displayed can be easily and immediately displayed. Furthermore, this control can be performed extremely easily by simply changing the memory section that serves as a buffer for the display 6 in the control section CT, and there is no need to perform work such as replacing the entire memory contents of the image memory section M. It also has a good effect. Therefore, as a result, the display screen can be moved continuously, and large-sized designs can be processed smoothly and efficiently.

In the above embodiment, the image storage unit M is large in the X-axis direction relative to the display screen, and the image storage unit M is shifted from side to side. It may also be possible to shift it up and down. Furthermore, the storage section may be large in both the X-axis and Y-axis directions, and may be shifted in the vertical and horizontal directions.

These selections may be made taking into account the size and type of design to be handled, the overall cost, etc.

As detailed above, according to the present invention, even if the design is large and cannot be displayed on the display at once, there is no need to replace the stored contents in the image storage unit many times, making it easy to As a result, a series of patterns can be checked and corrected extremely smoothly and with high efficiency.
