JPH03113623A - Method and device for correcting pattern displayed in flat display - Google Patents

Abstract

PURPOSE:To efficiently attain correction by partially enlarging and reducing a display pattern on a plate display, tracing it by means of a pen, storing an output signal from a transparent tablet in a memory and displaying the corrected pattern in the plate display through CPU. CONSTITUTION:Data processed in CPU is displayed in the plate display 1 as the prescribed pattern and once stored in the memory. The necessary area of the pattern displayed in the plate display 1 is partially enlarged and corrected. For correcting the pattern, a new curve is drawn on the plate display 1 by tracing the sheet surface of the tablet 2 by using the pen 4, the curve is stored in the memory and at the same time, it is displayed in the plate display 1 through CPU. Thus, correction work is simplified and is executed efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method and apparatus for modifying figures, patterns, etc. displayed on a display.

(Prior art) In recent years, drawing drawings using computers,
In many cases, designs are created, but it is not easy to modify figures and patterns once they have been input, and conventionally it has been done on a CRT screen using a keyboard or mouse device, or on paper. The method used was to print out the figures, modify the printed figures with a pen, and re-enter the revised figures using an image scanner or video camera. However, it is difficult to correct delicate free curves in figures drawn on a CRT screen using the method using the keyboard and mouse device described above, and it is difficult to correct minute free curves in figures drawn on a CRT screen. In order to make corrections, the entire figure must be divided and worked on, which takes a lot of time and reduces work efficiency. This type of work is not only necessary for modifying figures displayed on a CRT screen, but also for creating sketches for dynamic manga, and drawing each frame independently is time consuming and wasteful. Unable to express continuous movement. Therefore, it is more convenient to create by referring to the previous sketch, and being able to efficiently correct and change the seven shapes and patterns in this way is required in all fields.

(Objective of the Present Invention) As described above, the above-mentioned problems exist in modifying figures and patterns input to a computer, and the present invention is a technology developed with the aim of solving these problems. That is, the present invention provides a correction method and apparatus that can efficiently correct even fine and delicate curves without causing any problems.

(Structure of the present invention) The pattern correction device according to the present invention is composed of a plate-like display and a transparent tablet. Here, the plate-shaped display is a flat-plate display device, which may be of any type, such as a liquid crystal display or an ECL display, and the tablet is bonded to the surface of the plate-shaped display.

By the way, a predetermined pattern is converted into an electrical signal using an image scanner, a video camera, etc. and inputted into a computer, and the output signal of the computer is displayed on a plate-like display. By enlarging a portion of the screen displayed on the flat display and tracing a stylus on the tablet, a new line is stored in the computer's memory. Of course, the original line is programmed to disappear on output. Designs modified in this way can be printed out on paper, output as NC tape, or directly printed on NC tape.
It is also possible to control the C machine tool based on the design and process the workpiece.

Embodiments according to the present invention will be described in detail below based on the drawings.

(Example) FIG. 1 is a specific example showing a plate-like display with a tablet, in which 1 is a plate-like display, 2 is a tablet display, and the tablet 2 is fixed on the plate-like display 1 by fixing means. In addition to using fasteners such as screws,
An adhesive can also be used, and it is preferable that the plate-shaped display 1 and the tablet 2 are in close contact with each other without any gaps. Here, regardless of the model of the plate-shaped display 1, the CPU
The tablet 2 is an input device that detects the coordinate position by touching the surface of a flat transparent sheet with a pen. Pressure-sensitive conductive rubber or the like is used for detection.

FIG. 2 is a flowchart showing the pattern correction method of the present invention, and for convenience of explanation, the plate-shaped display 1 and the tablet 2 are shown separately. For example, a certain pattern is transmitted to the personal computer 3 using an image scanner, the signal enters the central processing unit (CPU) in the personal computer 3, and the data processed by the CPU is displayed on the plate-shaped display 1 as a predetermined pattern. Further, data processed by the CPU is temporarily stored in memory. The pattern displayed on the plate-like display 1 can be seen from the top surface of the transparent tablet 2, and the required area can be partially enlarged and corrected. To correct the pattern, a new curve is drawn on the plate-like display 1 by tracing the surface of the sheet of the tablet 2 with the pen 4, and the curve is saved again in the memory. Of course, here, the curved line of the original pattern is displayed on the plate-like display 1, overlapping the curved line of the original pattern. When the sheet surface of the tablet 2 is pressed with the ben 4, the pressure is sensed in an area of a certain radius centered on the ben 4, and the signal from the tablet 2 is input to the controller and the center of the pressure-sensitive area is sensed. The controller calculates and stores the X and Y coordinate values of the contact point of Ben 4 in the memory of the personal computer 3, and at the same time displays them on the plate-like display l via the CPU. Corrections may be made by partially enlarging the image, or may be made without enlarging it, but once the correction is completed, it is saved on a floppy disk. The revised new pattern is then drawn on the paper using an X-Y plotter.

Incidentally, in the flowchart of FIG. 2, there are no limitations on whether a signal from an image scanner is used as an input signal to the personal computer 3, or the type of input device such as a video camera or a shape measuring device. Also, the revised new pattern is X-Y
It can be used not only for drawing on paper with a plotter, but also for outputting to NC tape or directly as a control device for NC machines. Furthermore, since it is saved on a floppy disk, it can be used at any time and re-edited as needed.

As described above, the pattern correction method and device according to the present invention uses a transparent tablet to modify the pattern displayed on a plate-like display. You can get a great effect.

(Effects) (11) The present invention uses a transparent tablet to correct a pattern displayed on a plate-like display, and the correction work is extremely simple and very efficient. Since the entered design is enlarged or reduced by a simple electrical operation, it can be corrected without using a conventional medium such as paper.

(2) Furthermore, the correction method of the present invention corrects inappropriate portions with smooth curves or straight lines while the original pattern is displayed, making it possible to carry out corrections with particular emphasis on design. In mathematical processing, the aesthetic sense tends to be lost and there are many cases in which correction is impossible, but in the present invention, optimal correction can be made because the visual comparison is performed.
