Abstract

PURPOSE:To attain the highly efficient input of characters by setting dynamically an echo area and at the same time setting fine character sizes in the echo area. CONSTITUTION:An echo area set-up request is given to a system processor SP 1 from an input/output-only processor PP 2 at a time point when the first character to be read is inputted. Thus an echo area is set up based on an instruction of the SP 1. In this case, an echo area range can be designated together with the echo start and end positions. At the same time, the prescribed attributes related to characters including the height, the width ratio, and the space of input characters are given as parameters. Thus the highly efficient input is attained for characters.

For the purpose of this, the character/graphic processing device has a first means for notifying the system processor of an "echo area establishment request" from the input/output processor when a character with a reading is input; In addition to specifying the echo area range, a second means is provided that allows specifying the character size of input characters, etc.

[Industrial Application Field] The present invention relates to a character/graphics processing device that has an input/output dedicated processor and sets an echo area on an output display device to input characters, and particularly relates to a When inputting documents in Japanese, WYS IWYG (WHAT YOU
The present invention relates to a character input control method that realizes the SEEI S WHAT YOU GET method.

[Prior Art] FIG. 7 shows a system configuration diagram for explaining a conventional character/graphics processing device, in which 5l is a system processor (also simply referred to as rSPJ) that controls the entire device;
Reference numeral 52 represents an input/output processor (also simply referred to as rPPJ), 53 an output display device such as a CRT, 54 an input device such as a keyboard, and 55 a file in which various application programs are stored.

The following methods are available for inputting character strings in such conventional devices.

(1) Native input method In this method, the input/output processor (PP) 52 notifies the system processor (SP>51) for each character input from the keyboard 54, and the system processor (SP) 51 In this method, an input/output processor (PP) displays input characters on the output display device 153 based on instructions from the input/output processor (PP).

(2) Input method using echo For example, I SO (Linternational
Organization Stanclardiza
(So-CGI (Computer Graphics))
There is an eco one-type method defined by C Interface).

As is well known, as of November 1985, the ISO standard for graphical interfaces is as follows.

(1) High-level language interface (C, KS) defines coding rules for high-level language binding.

(2) Graphic device function set CC[:,I) Defines the graphic device function set.

(3) Graphic Metafile (CGM) Specifies coding rules for graphic metafiles. here,
GKS is Graphical Kernel System
ern's CGI is [:amputer Graphi
cs Interface, CGM is Compute
These are the respective abbreviations of Graphics Metafile.

The above rules are connected in the relationship shown in Figure 8, and C
GI is defined as a set of functions for realizing GKS, CGM defines elements that express graphics, and CGI is defined as CGM with a set of functions for controlling graphic devices. .

Products that are based on the above CGI function set, with additional functions for performance improvement, and product functions that assume advanced graphical operations such as CAD are also specified (for example, G1). The terms and conditions of the Fujitsu Limited version, which has expanded the functions of CG I, have been published as VDI (Vertua
1DeviceInterface).

In these ISO-CG I and VD [) systems, in the case of character string input, an echo can be used so that the operator can recognize the current value of the input device, and as shown in FIG. The character string inputted from is echoed and displayed on an output display device 53 such as a CRT. FIG. 10 shows a diagram for explaining character string input using echo, in which an echo area 56 is displayed on an output display device 53 such as a CRT, a cursor is displayed in the echo area 56, and a cursor is displayed according to the cursor. keyboard 5
4, input a character string (in this example, "Aiueo"), and when the input is completed, press the enter key on the keyboard, the key input becomes a trigger, and the characters input in the echo area 56 are displayed. The column is the system processor (
SP) 51 is notified.

[Problems to be Solved by the Invention] As explained in the prior art section, there are two input methods for character strings: (1) native input method and (2) I-So
-CG I. There are two types of VD 1st grade (7) x code and ita method.

In the native method (1), each input character is transferred from the input/output processor (PP) to the system processor (
SP) was notified of the deterioration in processing performance, and explained that the method using echo in (2) is basically intended for graphic input according to the ISO-CG ■ regulations, etc.
It is not suitable for detailed operations when inputting characters, and (a) When inputting a character string, an echo area must be set first, but the position of the first character the user inputs is actually unknown. Additionally, there is a limit to the capacity of the buffer area that can be allocated to the echo area within the input/output processor, making it difficult to set an appropriate echo area.

[Mouth] Only a rectangle can be set for the echo area, and details such as font size cannot be specified.

(c) X: ] -area i:: it, ISO-
CG I and VE) A predetermined background color specified by the 1 system is added.
