Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an image processing system for processing and displaying image information such as figures, and particularly for displaying character data along with image data on a CRT display. Concerning improvements to input display mechanisms in cases where

(Prior Art) An image processing system includes an image display mechanism that transfers a necessary portion of the contents stored in an image data memory to a VRAM, and an image display mechanism that transfers a necessary portion of the contents stored in an image data memory to a VRAM.
CRT control for displaying on the CRT display screen via 8! idJtill, a character input mechanism for writing characters into the image data memory, and an image processing generalization mechanism for controlling each mechanism, and displays the character data together with the image data on both sides of the CRT display. ing.

In this system, when displaying characters as images in image data such as figures displayed on the screen of a CRT display, the user uses a force to find an empty area on the screen and locate the character data display position. After determining the value, the character data is entered. In this operation, the position of the cursor is normally displayed at the position of one character that will be input next.

(Problems to be Solved by the Invention) However, with this character input method, it is difficult to predict where the second and subsequent characters to be input will be displayed. That is, unless the character input operation is performed carefully while appropriately setting the display area on the screen, the character will be displayed in the entire width of one screen determined by that line.

Therefore, once an input operation is incorrect, the image is synthesized in an overlapping state, making it difficult to correct it later.

This invention is intended to solve the above problems, and aims to prevent mistakes in the placement of character data by displaying in advance the area where character data will be input clearly for the user. .

(Means for Solving the Problems) In order to achieve the above object, the present invention transfers necessary portions of the contents stored in the image data memory to VRA.
a CRT control mechanism for displaying the transferred data on the screen of a CRT display via the VRAM; a character input mechanism for writing characters into the image data memory;
Equipped with an image processing control mechanism that centrally controls each mechanism,
An image processing system configured to display character data on the screen of a CRT display together with the image data, characterized in that a square generation mechanism for displaying the input position and size of the character data on both sides is provided. shall be.

(Function) According to the above configuration, when entering character data input mode,
By simply specifying the position where a character is to be displayed in advance, squares defining the area of the character string are displayed vertically and horizontally, and the characters to be input are limited to the squares.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 shows an image processing system according to the present invention.

In the figure, 1 is an overall control mechanism that controls the entire document processing system having an image processing function;
2 is an image display mechanism that transfers a necessary part of the contents stored in the image data memory 3 to the VRAM 4; 5 is a CR unit that transfers the transferred data via the VRAM 4;
A CRT control mechanism for displaying on the screen of the T-display 6, and a character input mechanism 7 connected to a keyboard or the like for writing characters into the image data memory.

The image display mechanism 2 and the character input mechanism 7
is under overall control by the image processing control mechanism 8.

The overall processing mechanism 8 has editing functions such as enlarging/reducing images and inputting character data to image figures displayed on the screen of the CRT display 6.

Further, a character square generation mechanism 9 is attached to the character input mechanism 7, and when an image processing mode is selected and characters are written on the image screen, a square of a predetermined row/column is placed at a specific position on the screen of the CRT display. This is for displaying.

Next, the operation of the image processing system having the above configuration will be explained.

First, during image processing, when the graphic mode is selected, the required image information stored in the image data memory 3 is loaded into the image display mechanism 2 under the control of the image processing generalization mechanism 8, and is transferred via the VRAM 4. and displayed on the screen of the CRT display 6.

Next, when character input processing is selected, the character input mechanism 7 synthesizes the character data input on the keyboard and the designated image data under the control of the image processing generalization mechanism 8. At this time, the character square generation mechanism 9, a large number of squares having the same size as the characters are displayed in a specific area on the screen of the CRT display 6, avoiding the image data display position, so that the rows and columns thereof are arranged at a predetermined pitch.

FIG. 2 shows the specific screen configuration. In this example, square 10 is in the first row and first column with the characters at the upper left corner, and I! to the right and below. They are arranged in a grid pattern.

The first row, first column is the location specified by the user with a cursor, etc., and this specified location is used as area specification data.A large number of squares with a size according to the number of character points, character spacing, and line pitch are II. Formed in the shape of an eye. Note that the number of points, character spacing, and line pitch are also set in advance by the user according to the size of the image.

If the user subsequently performs a character input operation, the character data will be written to fill each square 10 in order and will be displayed only within the specified area, so be careful not to overflow or overlap with image data. You can input without having to do so.

Note that square 10 is written only to the VRAM 4 and is only displayed on the screen of the display 6.
It is not written to the image data memory 3. Therefore, when the synthesized image data is hard-copied using a printer, plotter, etc., the squares 10 are not present, and only character strings according to the arrangement of the squares 10 are printed and displayed along with image images such as figures.

(Effects) As described above in detail through the embodiments, in the character input display mechanism in the image processing system of the present invention, when the character data input mode is entered, it is only necessary to specify in advance the position where the character is to be displayed. , the marks that set the area of the character string are displayed vertically and horizontally, and the input characters are limited to the squares, so there is no overlap with the image,
It is possible to eliminate troublesome processing such as deletion and repair work in case of emergency.
