Abstract

PURPOSE: To prevent character misdetermination and reduce the fatigue of an operator by displaying character data from a specific range specification part as data of standard size in reduced display mode without performing any reducing process. CONSTITUTION: When a new character is inputted during document preparation and a main control part 11 specifies the standard size, its character data are transferred to the specific range specification part 15. Then character data corresponding to a cursor position are inputted to a 2nd image memory of a display control part 13 with the control signal (b) from a cursor control part 19 and displayed on a display 14. When a KANA(Japanese character) - KANJI (Chinese character) converting process is performed, KANJI candidates as conversion results are displayed on the display 14 to the standard size. Thus, only while cursor specification is done and the KANJI conversion and a determining process for a character are carried out, the characters of the standard size are displayed. Consequently, character misdetermination is prevented to reduce the fatigue of the operator.

[Detailed Description of the Invention] (Summary) The present invention relates to a display device, and provides a method for displaying a portion of a standard size during reduced display on the display device,
The purpose is to make it easier to recognize data on the screen, and it consists of a data input section, a main control section that performs various controls in conjunction with data input, and a screen code that outputs image data based on commands from the main control section. A buffer, a display control unit that determines the size of the image data to be displayed, a display on which the image is displayed, and a specification unit that outputs standard size display commands in a specific range to the display control unit based on instructions from the main control unit. A range specifying section is provided, and part of the image data during reduced display is displayed in a standard size.

[Industrial application field]

The present invention relates to an image display device, and particularly to a display device capable of displaying a specific range of a screen in a reduced size in a standard size.

[Conventional technology]

Some display devices used in word processor workstations are capable of displaying characters and the like in a reduced size in order to display a large amount of information on one screen. A conventional example of a display device having such a reduced display function is shown in FIG. 5, for example. In this figure, numeral 1 is a keyboard for inputting characters, 2 is a keyboard control unit, and 3 is a microprocessor (hereinafter referred to as MPU).
4 is a screen code buffer in which various character codes are stored, 5 is a display control section that controls display operations, and 6 is a display that displays image information. In addition, since this display device is used in a word processor, it includes a kana-kanji conversion control section 7 that performs kana-kanji conversion based on commands from the main control section 3, a cursor control section 8 that specifies a word to be converted into kana-kanji with a cursor, and a kana-kanji conversion and an undetermined character control section 9 that sequentially sends the selected words to the display control section 5. In this display device, the display on the display 6 can be reduced in size, and when a key operation for instructing reduced display is performed from the keyboard 1, the main control section sends the information to the screen code buffer 4 and display control section 5. A screen reduction command is issued, and the screen is displayed in a reduced size on the display 6.

[Problem that the invention seeks to solve]

However, in such a conventional display device, once a reduction command is generated from the main control unit, all output data from the screen code buffer 4 is reduced and displayed on the display 6, so the operator cannot use the display. There was a problem in that the characters above 6 were difficult to read, which hindered the kana-kanji conversion operation and the discrimination operation when determining undefined characters.

The present invention has been made in view of such conventional problems, and an object of the present invention is to enable a part of a standard size display to be displayed during reduced display on a display device, and to facilitate recognition of data on the screen. It is.

[Means for solving problems]

FIG. 1 is a diagram showing the basic configuration of the present invention. In this figure, 10 is an input section for inputting data and commands, 11 is a control section, 12 is a storage section for storing character code data, etc., and 13 is a storage section for storing character code data, etc.
14 is a display, and 15 is a range instruction section for instructing a specific range on the display 14.

[Effect]

In the character input operation, kana characters or action instructions are input from the input unit 10. When a reduced display operation is instructed by this instruction input, the display control section 13 reduces the output data from the code buffer 12 and sends it to the display 14, and the reduced image is projected on the display. On the other hand, when new data is input from the input unit 10, that is, new characters are entered during document creation, this character data is transferred from the code buffer 12 to the specific range designation unit 15, where it is used for cursor control, etc. It is processed and transferred to the display control unit 13. The display control unit 13
The character data from this specific range specifying section 15 is not subjected to reduction processing and is output to the display 14 as standard size data, so the newly typed characters are displayed on the display 14 in a larger size than other characters. Is displayed.

〔Example〕

FIGS. 2 to 4 are diagrams showing an embodiment in which the display device according to the present invention is applied to a word processor. In this embodiment, 16 is a keyboard for inputting character data and operation instruction data, and 17 is an input section 1 together with the keyboard 16.
This is a keyboard control section that constitutes 0. A main control section 11 composed of an MPU is used as the control section, and a screen code buffer and display control section 13 operates according to instructions from the main control section 11 to display an image on the display 14. The specific range designation unit 15 includes a kana-kanji conversion control unit 18 that performs kana-kanji conversion based on commands from the main control unit 11, and a cursor control unit 19 that specifies a word or phrase to be converted into kana-kanji (i.e., a new input word or phrase) with a cursor. , confirms the words converted into kana-kanji and sequentially displays the control unit 1.
An undetermined character control unit 20 that sends the characters to 3 is incorporated therein. Then, when an instruction to perform a reduced display is given from the keyboard 16, a screen reduction command is issued from the main control section 11 to the screen code buffer 12 and the display control section 5, and the screen is displayed in a reduced size on the display 14.

FIG. 3 is a diagram showing an example of the configuration of the display control section 13. This display control section 13 is connected to the screen code buffer 12 by a data bus C, and has a first
image memory 21, a second image memory 22 that expands standard size image data, and a third image memory 23 that expands the output data of both image memories 21 and 22 into data for display on the display 114. It consists of And the first
The image memory 21 is connected to the cursor control unit 1 by a signal line a.
The second image memory 22 is connected to the cursor control section 19 and the undefined character control section 20 through a signal line.

The operation of the display device having such a configuration will be described below.

In the flowchart of FIG. 4, when characters are input from the keyboard 16 in processing step (hereinafter referred to as ST) 1, in Sr1, the main control unit 11
Check whether U is being displayed in a reduced size. If it is determined by this check operation that the display is being reduced, S
At r1, the undetermined character control unit 20 is activated and checks whether the input character is undetermined. If it is determined that the typed character is undetermined, it is checked in Sr1 whether or not the display on the display 14 is specified to be displayed in a standard size. And ST2~
When a NO determination is made in each processing step of ST4, the process moves to Sr1, where the kana-kanji conversion control unit 18 performs normal kana-kanji conversion processing according to the display state, and after this kana-kanji conversion processing, the series of processes ends. .

On the other hand, if it is determined in Sr1 that standard size display is specified, the process moves to Sr1 and a standard size display process is performed at the cursor position of the undetermined character. As a result, the character data corresponding to the cursor position is transferred to the cursor control unit 19.
The image is inputted to the second image memory 22 by a control signal sent from the signal line through the signal line and displayed on the display 14. Next, when the kana-kanji conversion process is performed in Sr1, the kanji candidates resulting from the conversion are displayed in standard size on the display 14 in Sr1. While this display continues, character confirmation processing and determination processing are performed in the next Sr1, and in the following 5TIO, it is checked whether or not the character has been confirmed. If the character has not yet been determined by this check process, the process returns to step Sr1, while if it is determined that the character has been determined, the process moves to 5TII and the character is redisplayed according to the display state. . In this way, only a part of the characters are displayed in the standard size on the display 14 only while the cursor is specified and the kana-kanji conversion and character confirmation processing are being performed.

(Effects of the Invention) As explained above, according to the present invention, characters in a specific range are displayed in standard characters in the reduced display mode of the display device, so it is convenient for the operator to convert input characters to kana-kanji. Moreover, when confirming the characters, it becomes possible to clearly recognize the characters displayed on the display. For this reason, various effects can be obtained, such as preventing typing errors and character confirmation errors during document creation, and reducing fatigue of the operator typing characters.
