Abstract

PURPOSE:To construct a displaying system capable of displaying the easy-to-read data image with a large size without decreasing the data quantity able to be displayed on a displaying screen. CONSTITUTION:The title system is equipped with a position designating device 1 to set an arbitrary position or the area on the screen of a display 5, a font memory having at least two kinds of the font image including the font image of a basic size, and a position recognizing display 3 to recognize the attribute of the position data sent through the position designating device 1 and the data to be displayed at the position, obtain the necessary image from a font memory 1 and perform the displaying, and at the position or the area designated by the position designating device 1, the font image of the size larger than the font image displayed at other position or area is displayed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display system that is the core of a man-machine interface.

0002

2. Description of the Related Art In recent years, display devices, which are the core of man-machine interfaces, are required to have increasingly sophisticated functions.

Conventionally, when displaying text data on a display, all data was displayed as a font image of the same size, except for double-width editing in a word processor or the like. Double-angle editing in a word processor or the like is also for fixed data, and when the screen is moved (scrolled), the data image displayed in double-angle moves.

[Problems to be Solved by the Invention] According to the above-mentioned conventional example, all data is displayed using font images of the same size. The image (font image) becomes small and difficult to read. Conversely, increasing the size of each data image reduces the amount of data that can be displayed on one screen of the display.

The present invention has been made in view of the above circumstances, and provides a display system capable of displaying large-sized and easily readable data images without reducing the amount of data that can be displayed on a display screen. The purpose is to

[0006]

[Means for Solving the Problems] The display system of the present invention includes a position specifying device for setting an arbitrary position or area on a display screen, a font image of a basic size and at least one type of font image of a size larger than the basic size. When displaying data on the display screen, it recognizes the position or area data set by the position specifying device and the attributes of the data to be displayed in that position or area, and displays the necessary image. and a position recognition display device that obtains and displays the font from the font memory.

[0007]

[Operation] In the present invention, when displaying text data, graphic data, etc. on a display, a position specifying device is used to display all or part of these data as images of two or more sizes on the display. It recognizes the position or area data sent through the font and the attributes of the data to be displayed in that position or area, obtains a font image larger than the basic size from the font memory, and displays it. This makes it possible to display a font image displayed at a designated point or area on the display in a larger size than font images displayed at other points or areas.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall configuration diagram showing an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a position specifying device consisting of a pointing device such as a keyboard and a mouse. The position specifying device 1 allows a user program or the like to specify a position or area to be emphasized on a display, and sends it to a position recognition display device 3, which will be described later.

Reference numeral 2 denotes a font memory in which a font image (font data) of a certain specific size (basic size) is stored, and at least one type of font image of a size larger than this basic size is stored. . That is, the font memory 2 has font images of at least two different sizes for the same font, including a font image of the basic size.

Reference numeral 3 denotes a position recognition display device, which is specifically composed of a CPU and a display controller. The position recognition display device 3 basically generates display data using the CPU, stores it in the video RAM 4, reads out the information using the display controller, and displays it on the display 5. Further, the position recognition display device 3 recognizes the data of the position among the data to be displayed on the display 5 according to the position information sent from the position specifying device 1,
A font stored in a font memory 2 is selected and displayed using a font of a basic size, or a font of a size larger than the basic size is used and displayed with an image emphasized more than at other display positions.

Reference numeral 4 indicates video R in which display data is stored.
AM, and the CPU with built-in position recognition display device 3 mentioned above.
In addition to generating and storing display data, image data is read from the font memory 2 and stored in the video RAM 4.
Expand on top. Reference numeral 5 denotes a display (display device) composed of a flat panel such as plasma, liquid crystal (LCD), or CRT, which displays the display data in a visible form.

The operation of the embodiment of the present invention will be explained below. First, the position specifying device 1 is provided to allow the user or a user program to specify a highlighted position or area on the display 5, and the position information specified by the specifying device 1 is sent to the position recognition display device 3. It will be done. Here, the emphasis position or area on the display 5 is, for example, the current cursor row/column in the case of user input or file access, and the final output row/column in the case of data output display by a program. It becomes a column/area.

The position recognition display device 3 recognizes the data corresponding to the position or area sent by the position specifying device 1 among the data to be displayed given by the user or the user program, etc., and stores the data in the font memory 2. access. This font memory 2 stores 2 data images.
In order to display the same character font in different sizes, at least two sizes of font images are provided for the same character font, as described above.

Therefore, the position recognition display device 3 receives data corresponding to the position or area sent by the position specifying device 1 from the font memory 2, which is a font image corresponding to the data, and then transfers it to another position or area. A font image of a larger size than the font displayed on is obtained and displayed on the display 5.

As described above, in the embodiment of the present invention, when displaying data such as text on the display 5, fonts (data) are used to display all or part of the data as images of two or more sizes. A position specifying device 1 for specifying a position on a display 5, a font memory 2 having font images of at least two different sizes, and a position recognition display device 3 are provided. The position recognition display device 3 recognizes the position on the display 5 specified by the user or by a user program,
Controls the data to be displayed in the area (row, column, etc.) that includes that position to be displayed in a larger image than the image of the data displayed in other areas. At this time, the amount of data displayed on the entire display by displaying a specific area larger is smaller than that of one line compared to the conventional method, for example, if the data in the row containing the specified position is displayed as an image that is twice as large vertically as the image in other rows. It just gets smaller.

[0017]

Effects of the invention: A large amount of information can be displayed on the display screen, and information in highlighted areas (for example, input lines, search words, cursor lines when reading, areas specified by the mouse, etc.) can be displayed in a large size and readable. It can be displayed easily and easily identified, contributing to the further development of man-machine interfaces.
