Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Application Field) The present invention uses a display device, particularly a color screen display device as a display means of a man-machine interface, and also a method for recording/recording the display screen. The present invention relates to a display device with a color hardcopy device for storage.

(Prior Art) As computers become more sophisticated and cheaper, computers are being used in many areas such as office processing, chemical technology calculations, design, and plant process monitoring. In such computers, CRT display devices are widely used as display devices for man-machine interface means, and color CR7 display devices have also come to be used in addition to the conventional monochrome CRT display devices. There is. Additionally, along with this trend, hard copy devices for recording/storing CRT screens are also being used in combination with color hard copy devices capable of displaying multiple colors.

A conventional example of such a display device is shown in FIG.

In the figure, a display means 1 includes a display data memory 2 that stores display data such as characters and figures to be displayed, and a display color memory 2 that stores a display color specification table that specifies the color of each character and figure. Based on the data read from the specification table 3, display commands are output to the color CRT display device 5 via the input/output means 4.

As a result, characters, figures, etc. are displayed on the color CRT display device 5 in the specified color.

Further, when the hard copy request switch 6 is turned on, the hard copy request receiving means 7 detects it at a predetermined timing, and the hard copy request receiving means 7 then transmits the information to the color CRT display device via the input/output means 4. 5, a hard copy command is output.

As a result, the image being displayed on the color CRT display device 5 at that time is recorded and output from the color hard copy device 8.

Here, as shown in FIG. 8(a), the display data stored in the display data memory 2 includes attribute data for identifying the shapes of characters and figures to be displayed, and for specifying the display position. It consists of coordinate data, size data, etc. Further, the display color specification table of the display color specification table memory 3 stores color codes for specifying the display color of each display data, as shown in FIG. 3(b).

(Problems to be Solved by the Invention) By the way, the color CRT display device 5 is becoming more and more sophisticated.
At the same time, multi-color display such as 16 colors, 256 colors, or even 4096 colors is possible. On the other hand, in the color hard copy device 8, a device capable of color expression equivalent to the color CRT display device 5 is very expensive and requires a very long time for recording and outputting. therefore,
The color hard copy device 8 is usually a color CR.
A device that can express fewer types of colors than the T display device 5 is used.

Therefore, colors that can be displayed on the color CRT display device 5 but cannot be recorded on the color hard copy device 8 are converted into colors that can be recorded on the color hard copy device 8 according to a certain relationship, and are printed and output.

However, in this conventional method, color CRT
Since the colors that can be identified on the display device 5 are recorded and output in the same color on the color hard copy device 8, even if the display colors are designed to be easy to see on the screen of the color CRT display device 5, the color hard copy device 8 This caused the inconvenience that the copy was not always easy to read.

Therefore, an object of the present invention is to provide a display device that can record and output an easy-to-read color hard copy.

[Structure of the Invention] (Means for Solving the Problems) For this purpose, the present invention provides a hard copy color specification table means for specifying a color when recording and outputting with a hard copy device, and a hard copy request. If so, a color image is displayed on the color screen display device in a color based on the hard copy color designation table means, and the displayed contents are recorded and output as a color hard copy from the color hard copy device.

(Function) Therefore, a color hard copy specified in a display color that can be recorded by the color hard copy device is recorded and output, so that an easy-to-read color hard copy can be obtained. Furthermore, since the color hard copy is displayed on a color screen display device, the color specification at that time can be changed as appropriate, and a more effective color hard copy can be obtained.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a display device according to an embodiment of the present invention. In this figure, the same parts and corresponding parts as in FIG. 7 are designated by the same reference numerals, and the explanation thereof will be omitted.

In the figure, a hard copy color specification table memory 11 stores a hard copy color specification table for specifying a color corresponding to each display data so that the color when recorded and output by a color hard copy device 8 is easy to see. It is something. Note that the color designation is made in advance by an operator or the like.

The colors specified in this hard copy color specification table and the colors specified in the display color specification table mentioned above are, for example,
The relationship is as follows.

In other words, 90% red in the 1 display color specification table.

A color shown as 10% green is specified as 100% red in the hard copy color specification table, and a color shown as 10% red and 90% green in the 1 display color specification table is specified as 100% green in the hard copy color specification table. Specified as %.

The color specification switching means 12 is for switching between the display color specification table memory 3 and the hard copy color specification table memory 11 and connecting it to the display means 1. The switching is performed by the hard copy request receiving means 7. It is controlled by a hard copy request processing means 13 which instructs the input/output means 4 to request a hard copy by outputting it.

With the above configuration, 1 normally, the hard copy request processing means 13
In this case, the display color designation table memory 3 is selected by the two-color designation switching means 12.

Therefore, as shown in FIG.
sequentially outputs the color information from the display color designation table memory 3 to the display means 1. As a result, at this time, the display means 1 transmits the display data stored in the display data memory 2 to the color CR7 display device via the input/output means 4 so as to display the display data stored in the display data memory 2 in the color designated by the display color designation table. Output the drawing command to 5 (201, 202, 20
3,204).

As a result, data is displayed on the color CR7 display device 5 in the color specified by the display color specification table.

When the hard copy request switch 6 is turned on and detected by the hard copy request receiving means 7, as shown in FIG. 12 to select hard copy color specification table memo + Jii (30
1).

As a result, the color designation switching means 12 sequentially outputs the color information from the hard copy color designation table memory 11 to the display means l (205 in FIG. 2). A drawing command is output to the color CR7 display device 5 via the input/output means 4 so as to display the display data stored in the hard copy color specification table in the color specified by the hard copy color specification table (302
).

As a result, data is displayed on the color CR7 display device 5 in the color specified by the hard copy color specification table.

Next, the hard copy request processing means 13 performs input/output processing.

A hard copy command is output to the color CR7 display device 5 via the means 4 (303).

As a result, the color CR7 display device 5 records and outputs the currently displayed screen on the color hard copy device 8.

When the color hard copy by the color hard copy device 8 is completed (304), the hard copy request processing means 13 causes the color designation switching means 12 to select the display color designation table memory 3. As a result, the display contents of the color CR7 display device 5 return to the original display (305, 3
06).

In this way, when a color hard copy is requested, the display content of the color CR7 display device 5 is changed to display the color set in the hard copy color specification table, and the color hard copy device 8, the color hard copy is very easy to read.

In addition, by looking at the display contents on the color CR7 display device 5, the operator can check the color specification status of the color hard copy, so if the operator is dissatisfied with the color specification status at that time, he or she can change it. can.

Incidentally, recently, a color CR7 display device has been provided which allows characters, figures, etc. to be displayed on the screen to be managed individually in segments. For such a color CR7 display device, by outputting a command specifying the display color of each segment, the display color of characters, figures, etc. of the corresponding segment on the screen can be determined. Color CR
Another embodiment of the present invention is shown in FIG. 4, using a 7 display device. In this figure, the same parts and corresponding parts as in FIG. 1 are given the same reference numerals, and the explanation thereof will be omitted.

In the figure, a display data memory 2 stores data representing characters, figures, etc. to be displayed in segments. The display segment color specification table memory 14 stores a display segment color specification table that contains color specification information when each segment is displayed on the color CRT display device 5. The hard copy segment color specification table memo January 5 stores a hard copy segment color specification table that contains color specification information when each segment is recorded and output by the hard copy device 8.

The segment color designation switching means 16 switches between the 5-display segment color designation table memory 14 and the hard copy segment color designation table memory 15 and outputs it to the segment color information setting means 17.

The segment color information setting means 17 outputs segment color information to the color CRT display device 5 via the input/output means 4.

Normally, the display means 1, based on the data in the display data memory 2 and the display segment color specification table memory 14,
A drawing command for each segment is formed and outputted to the color CRT display device 5 via the input/output means 4. As a result, each segment is displayed on the color CRT display device 5 in the color specified in the display segment color specification table.

When the hard copy request switch 6 is turned on, the segment color designation switching means 16 selects the hard copy segment color designation table memory 15 by the action of the hard copy request processing means 13.

Thereby, the segment color information setting means 17 instructs the color CRT display device 5 via the input/output means 4 to switch the color of each segment to the color specified by the hard copy segment color specification table.

As a result, the display contents of the color CRT display device 5 are switched to a display corresponding to the hard copy segment color specification table.

When the hard copy request processing means 13 outputs a hard copy command to the color CRT display device 5 via the input/output means 4, the display contents at that time are recorded and output by the color hard copy device 8.

When the output of this hard copy is completed, the segment color specification switching means 16 selects the display segment color specification table memory 14, and thereby the segment color information setting means 17 selects the display segment color specification table memory 14. The color CRT display device 5 is instructed to switch the color of each segment via the input/output means 4, and as a result, the display contents of the color CRT display device 5 return to the original display.

According to this embodiment, when changing the display content on the color CRT display device 5, it is only necessary to change the color information of the segment, so that the time required for the process can be shortened.

Furthermore, some color CRT display devices use a color lookup table in order to reduce the capacity of the data memory they are equipped with.

For example, when the three primary colors red, blue, and green are each expressed as 8-bit data and each is expressed in 256 steps,
In order to store an image, a memory capacity of 24 bits per pixel is required. Therefore, if the resolution of a color CRT display is 1024 x 1024 pixels, approximately 3 megabytes of image memory will be required.

The color lookup table stores one color number and 24-bit data that indicates the color corresponding to that color number. Therefore, if one color number in the color lookup table is composed of 4 bits, The memory capacity required to store images of the same resolution is approximately 0.5 megabytes. However, in this case, the number of colors that can be displayed simultaneously is 16, which is an arbitrary combination of colors that can be displayed on a color CRT display device.

Still another embodiment of the present invention using such a color CRT device is shown in FIG. In addition.

In this figure, the same parts and corresponding parts as in FIG. 1 are given the same reference numerals, and the explanation thereof will be omitted.

In the figure, a display lookup table memory 18 stores a color lookup table for displaying one display data on the color CRT display device 5, and a hard copy lookup table memory 19
is used to store a color lookup table when one display data is recorded and output by the hard copy device 8.

The color lookup table switching means 20 switches between the 1 display lookup table memory 18 and the hard copy lookup table memory 19 and outputs it to the color lookup table setting means 21. , input/output means 4
The color lookup table 5a set in the color CRT display device 5 is rewritten via the color CRT display device 5.

Normally, display lookup table data is set in the color lookup table 5a of the color CRT display device 5 by the display means 1.

As a result, data is displayed on the color CRT display device 5 in the color specified in the one-display lookup table.

When the hard copy request switch 6 is turned on, the hard copy request processing means 13 causes the color lookup table switching means 20 to select the hard copy lookup table memory 19.

Thereby, the color lookup setting means 21 sets the color lookup table 5 of the color CRT display device 5.
a is rewritten to the contents of the look-up table for hard copy, thereby switching the display contents of the color CRT display device 5 to a display corresponding to the look-up table for hard copy.

When the hard copy request processing means 13 outputs a hard copy command to the color CRT display device 5 via the input/output means 4, the display contents at that time are recorded and output by the color hard copy device 8. After outputting this hard copy, the color lookup table switching means 20 selects the display lookup table memory 18, and thereby the color lookup table setting means 21 selects the color lookup table memory 18 of the color CRT display device 5. 5a is rewritten with the contents of the hard copy lookup table, and as a result, the display contents of the color CRT display device 5 are restored to the original display.

In this embodiment, since it is only necessary to rewrite the contents of the color lookup table 5a in the color CRT display device 5, the processing time can be significantly reduced.

Furthermore, compared to the embodiments described above, the configuration is simpler because a color designation table memory, a segment color designation table memory, etc. are not required.

In each of the embodiments described above, all the color information for display and color hard copy is specified to the color CRT display device 5, but only the different color information among these color information is specified to the color CRT display device 5. You may specify it and rewrite it.

Another embodiment of the present invention in such a case is shown in FIG. This embodiment is different from the embodiment shown in FIG. , the contents of the hard copy color specification table stored in the hard copy color specification table memory 11 are compared, and display data whose display colors do not match are input/outputted so as to be displayed in the color of the hard copy color specification table. A color code determination display means 22 is provided for instructing the color CRT display device 5 via the means 4.

In addition, 5 this color code determination display means 22, when the color hard copying device 8 finishes color hard copying,
The content of the display color specification table is compared with the content of the hard copy color specification table, and display data whose display colors do not match is output to the color CRT display device 5 via the input/output means 4 in the color of the display color specification table. As a result, the display contents of the color CRT display device 5 are restored.

It should be noted that the same configuration as the embodiment shown in FIG. 6 can be applied to structures other than those shown in FIG. 1.

[Effects of the Invention] As described above, according to the present invention, when a color hard copy request is made, a color hard copy specified in a display color that can be recorded by a color hard copy device is recorded and output. You can get an easy-to-read color hard copy.
