Abstract

PURPOSE:To obtain an easy-to-see hard copy by copying display data which is inputted temporarily on paper, etc., with resolution corresponding to enlargement magnification. CONSTITUTION:CRT display data DIN1,... DIN4 which are inputted through the input/output interface 6 of a CRT controller 5 are transferred to a specific area A on a frame memory 7. In this case, information which is transferred to the specific area A temporarily is inputted to an enlargement area, increased in only line length in an enlargement area corresponding to the copy size magnification of a hard copy terminal 11, and transferred as hard copy interface input data HCD to a hard copy interface 10. The hard copy terminal 11, on the other hand, is replaced with a terminal with large copy size magnification and then information is copied on paper, etc., with the hard copy start signal hcs of the hard copy interface 10. Consequently, the resolution is increased and the image becomes easy to see.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a display processing device as a peripheral device of a computer system.

(Prior Art) In general, full graphic color CRT display devices used as peripheral equipment for computer systems include a full graphic color CRT display device (hereinafter abbreviated as CRT) and a full graphic color CR,'r'' display control device (hereinafter abbreviated as CRT). A hard copy device (hereinafter abbreviated as HC) is connected with a signal line, and information such as figures, characters, symbols, etc. displayed on the CRT can be transferred at the operator's request. The information is then printed out (hereinafter referred to as hard copy) using dHc and recorded.

(Problem to be Solved by the Invention) With the recent increase in the density of graphic and character information such as distribution system map information, the copy size of HC has been expanded to create single-line diagrams of arbitrary distribution lines, arbitrary substations, etc. There is a demand for hard copies of single-line diagrams with increased resolution in bank units, and simply converting a single HC to a device with a large copy size will not be able to handle the graphics and character information displayed on the CRT, especially the line thickness and characters. However, the symbol size etc. are only enlarged and copied in proportion to the copy size of the HC alone, and the resolution does not increase in accordance with the enlargement magnification of the HC alone.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a display processing device that increases the resolution according to the magnification of a single hard copy.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention provides a full graphic color CRT display device, a full graphic color CR1 display control device, and a hard copy device as peripheral devices of a computer system. is connected to the display processing device by a signal line, an enlarged area is provided that increases the resolution according to the magnification that is hard-copied to the frame memory of the full graphic color CR1 display control device, and the hard-copy interface and hard-copy terminal are used for printing. The copy size is replaced with a larger one, and the hard copy is configured to be enlarged in accordance with the copy size enlargement ratio of the hard copy device.

(Function) The display data taken in via the input means is once entered into a specific area in the frame memory, a resolution corresponding to the enlargement factor of the copy size is given in the enlarged area, and the result is hard-copied. Ru.

(Example) Examples will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a display processing device according to the present invention.

In Figure 1, ■ is a calculator, 2 is a keyboard, 3 is a tablet, and 4 is a joystick.
It has a configuration in which it is connected to the T-controller 5 and displayed on a color display 9, and is also output to a hard copy terminal 11.

The CRT controller 5 also has an input/output interface 6 and an MPU memory 13 via a local bus 14.
A system bus 15 connected to the PU 12 and the MPU is connected to a color display 9 via a frame memory 7 and a color map 8, and the output of the color map 8 is connected to a hard copy interface connected to the system bus 15. 10, and this hard copy interface 10 and hard copy terminal 11 are connected.

Next, I will explain the effect.

Output from computer 1 or keyboard 2゜tablet 3. C captured from input from joystick 4
RT display data DIN1. ...I) IN4 is CRT
The data is transferred to a specific area A of the frame memory 7 via the input/output interface 6 of the controller 5. Of these, only the color information of each bit is transferred to the color map 8 as color specification information, and the information of a specific area A is paired with the information of the color map 8 and displayed on the full graphic color CR'l' display W9. .

At this time, the information transferred to the specific area A in the frame memory 7 is input to the enlargement area LA in the frame memory, and then in the enlargement area LA according to the copy size magnification (fixed) of the hard copy terminal 11.

The size of the characters and symbols and the thickness of the lines must not be changed - 5 - Only the vector information, that is, the length of @, is enlarged and transferred according to the copy size magnification, and the information in the enlarged area LA is transferred via the color map 8. The data is then transferred to the hard copy interface 10 as hard copy interface input data HCD. On the other hand, by replacing the hard copy terminal 11 with a terminal having a larger copy size magnification than the conventional one, information is hard copied as shown in FIG. 2 by the hard copy activation signal hcs of the hard copy interface 10.

Note that each process in the CRT controller 5 described above is performed by the CRT controller 5.
Microprocessor (MPU) 1 in RT controller 5
2 and MPU memory 13, and a local bus 14.2 is connected between each module. They are connected via a system bus 15.

Therefore, depending on the hard copy method according to this invention,
As shown in FIGS. 2 and 3, the information displayed on the color CRT display 9 has a higher resolution at the enlarged copy size compared to the conventional copy size for the same amount of information. For example, if the copy size is doubled in terms of the area ratio of the conventional size, the distribution system map information will be able to include twice the amount of information on the map range.

In other words, with the conventional method, in extreme cases where there is a large amount of information, even if you replace it with a hard copy terminal with a larger copy size and make hard copies, the resolution will not change and the line will increase in proportion to the magnification. becomes thicker, and the size of the characters and symbols becomes larger.21 It becomes difficult to distinguish easily.

In short, until now, information in a specific area A in the frame memory 7 has been transferred to the hard copy interface 10 via the color map 8 by the hard copy activation signal hcs of the hard copy interface 10, and as a result of being output to the hard copy terminal 11. As shown in Figure 3, it was hard: 1 piece.

In the above example, the copy size was explained as an example of doubling, but
Although not limited to this, it is possible to increase the copy size by n times the conventional size by increasing the capacity of the frame memory (not shown in the figure) or by using a color hard copy device of a corresponding size. It can also be used in a display processing device capable of copying.

[Effects of the Invention] As explained above, in the present invention, once input display data is given a resolution according to the enlargement magnification.

It is possible to obtain a hard copy that is extremely easy to read.
