Abstract

PURPOSE:To make an easy and accurate information input possible, by subjecting picture information to compression processing in accordance with the number of scanning lines of a display and displaying this information as a contracted picture and designating coordinate positions while restoring and processing the picture near designated coordinate positions on the display screen. CONSTITUTION:Original picture information is stored as binary data in a memory 1. A contraction converting device 2 subjects this original picture to the picture contraction processing to convert it to contraction multilevel pattern data having a small number of scanning lines. In this conversion, each picture element is weighted to obtain picture element data of representative points. Then, multilevel contraction picture information having variable density gradations is stored in a display memory 3. This information is read out for every picture element and is displayed as a picture having gradations on a display 4. The whole of one-screen components of the original picture is displayed in this picture, and positions on the screen correspond to those of the original picture, and positions on the screen correspond to those of the original picture. Consequently, the whole of information is easily grasped from this overall picture, and prescribed information is indicated easily with a light pen 5 and is inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a display C; an information input device for inputting one of the displayed nine information by specifying the position coordinates of the display screen;

There is an information input device that selects one piece of information from a set of information and inputs its information code.

Typical examples are tablets, and in recent years, devices that use a display and light pen to input information through dialogue between an information system and an operator have been introduced.
8. Using this display and a light pen, the display screen C displays nine information as two figures.

A light pen (2) indicates the position coordinates on the display screen, and inputs the code information of the 9 information displayed at the right position.

However, conventionally, the information displayed on a display is often in the form of general C2 binary coded patterns, and there is often a limit to the amount of information that can be shown on the display screen at one time.For example, the character pattern t- When displaying, the number is determined by the ratio of the number of scanning lines on the display and the minimum number of scanning lines needed to read one character pattern (2).For this reason, if there is a large collection of information to select, for,
It is necessary to display each piece of information in the set separately several times, and the operator checks all of the displayed information.
It is necessary to enter information after understanding the whole situation, etc.
The handling burden is heavy and 9.

In other words, when inputting general C2 information and expressing document information etc. as a character pattern, it is often the case that one page of a normal document is grouped into two pieces of the same size as each other, and this can be visually displayed as a pattern. For display, C is approximately $ scanning line/
Is there a need to ensure a degree of resolution comparable to that of WJI? In order to satisfy these conditions, it is necessary to display an image of about the size of the above-mentioned 4th edition in 1728 x 2304 pixels horizontally and vertically.

On the other hand, most ORT devices commonly used as displays and 7-player devices conform to the television standard format and display images in the C522X'1OOOWJ collection. ), in order to display an image well using such a display, only 1/9 m degree of the above document can be displayed at a time, so it is very difficult to grasp the entire information (2). Unfortunately, the above-mentioned inconvenience has occurred.

The present invention was made in consideration of these circumstances, and its purpose is to effectively display a large amount of information (:1.-[(2) using an inexpensive display with a low number of scanning lines. C: 1. Specify the position coordinates of the display screen for one of the nine pieces of information displayed. M: A simple information input device that can be operated by only two people. To provide (: Yes.

The outline of the present invention is to reduce and compress image information according to the number of scanning lines of the display (62) and display it as a reduced image. By specifying the position x=m, it is possible to input information easily and accurately.

Hereinafter, one embodiment (two embodiments) of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic configuration of the apparatus of the embodiment, and numeral 1 in the figure is a companion memory in which document pattern information is stored as binary image data. The binary image data stored in the memory 1 is read out to the reduction conversion device 2, subjected to Ski & reduction processing I18, and stored as multi-value reduced image data in the display memory J1. Then, the circular mesh small image data stored in the display memory J is supplied to the display 4C, and the entire data is displayed as a small image with -m taps.

In addition, the light pen 5 is connected to the display l&1 on the display 4.
The position on IIthI is selectively specified, and the designated coordinate position 7 is determined and detected by the position determination device I62. By reading out the information stored in the image information on the memory 1 at the specified coordinate position of the insect with the information of the specified coordinate position detected by the robot C2, it becomes possible to input the specified information. Note that 1 in Figure 1 indicates the display operation of the display 4,
A control device which operates synchronously with the display scanning position of the first scanning line, and which provides the position information for the position determination and also controls the reading of data from the memory 1 and the processing of the reduction conversion device 1. It controls the operation and data writing/reading of memory 3, respectively.

Now, original image information, such as document pattern information, is stored as an image in the memory 1 in the form of visual pattern information using a fixed partial area (ie, one spindle or symbol). This image information consists of binary data, for example, a scan in which 9 pattern information is written on a sheet of paper in 7 axes, etc. 4 = [Scan 2]
It may be a commonly used pattern data, or it may be a binarized pattern data generated by an electrical pattern generator such as a character generator.

With such binarized pattern data, for example,
A single original image with a size of about the same size as a printing plate, and a trench 9 document image are formed.

For a document image (Jj!j image) C2 such as Reduced multi-value pattern data 6: Converted. This multivalued data displays one pixel as information with gradations. That is, the number of scanning lines is much greater than that of the display 4 (:
Each binarized pixel data of the original image expressed by a large number of scanning lines is divided into blocks, for example, as shown in FIG. and these Il!II
Raw data, j e ``mu+lB~9 heat i◆m-''
eje "l', j+1 to ml+n+l, 11.1 - For example, if a predetermined weighting coefficient rk is applied to these data
1 is multiplied and then averaged, and the drawing data is reduced for each pixel data region of the representative point bkl, and these small data are sequentially stored in the display memory 142. This-
2. Therefore, the display memory 3C2 has gradations of linear density.
This means that the multilevel reduced image information is stored.

The nine multilevel reduced image information stored in the display memory 1 is then read out for each pixel in synchronization with the laboratory scan 62 of the display 4, and after D/MU conversion, it is displayed as luminance information on the display 4. Two images are supplied and displayed as an image with five gradations. This displayed good image is % original! Bandwidth is limited for the entire screen of the Ii image, resulting in a slightly blurred image, but the position on the display screen is at the same position as the original image. teeth,
Since the information lost due to the reduction in the number of scanning lines C2 is compensated for by the gradation, the unit information pattern in that partial area-2 is visually ζ; It will be done.

Therefore, it is possible to ascertain the entire 1li11I information from the entire image displayed at once with C2 as shown in the figure. , it becomes possible to specify the specified information using the light pen 5 in a simple manner (2, and 11) and input 1 information.Moreover, when trying to specify the coordinate position more precisely (2), it is possible to input 1 information. Second is.

It is directed by the light pen 642 of the reduced display image and is centered on the Nine-Za Jin-Iden. It is advisable to partially enlarge the image in the vicinity of S2, and instruct the coordinate position again for this enlarged display image S2. All you have to do is change the image reduction magnification in =.If you do this,
First of all, Hara +1! Hierarchical information that allows you to display the entire area and get an overall understanding of it, and then obtain an enlarged image of the vicinity by specifying the position strategically and specifying the coordinate position with high precision. It is possible to input condolence information with high accuracy based on the understanding. Therefore, it has a great practical effect, such as greatly reducing the operator's negative impact by 62 and simplifying handling.

Note that the present invention is not limited to the above embodiment C2,
911 For example, the reduction magnification of the original image is the J size of the original image and its 4i! It can be determined by taking into consideration the size of the display and the number of scanning lines.Also, it is also possible to use a touch sensor or a tablet other than the light pen 6 as the coordinate position indicator. In short, the present invention can be implemented with various modifications without departing from the gist thereof.
