Abstract

PURPOSE:To display color data on monochrome CRT and to transmit color information, as well to an operator by disposing a CRT kind detection part, a display data generation part, a pattern selection part and a pattern conversion part, etc. CONSTITUTION:Data from the display data generation part 1 is transmitted to a switch 3, and the data is transmitted to the pattern selection part 4 in accordance with the data on CRT from the CRT kind detection part 2 in the case of monochrome CRT. The selection part 4 selects a corresponding pattern by using a color corresponding pattern selection table based on the input data, and the selected pattern is transmitted to the pattern conversion part 5. The conversion part 5 converts the selected pattern into a display pattern by using a pattern conversion table, and outputs it to the pattern generation part 6. The generation part 6 generates the pattern in accordance with the display pattern, and it is displayed by a display part 7. Thus, color data can be displayed on monochrome CRT, and the color information can be transmitted to the operator, as well.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to data display for personal computers and the like, and particularly to a method for displaying color data in monochrome CRTiC'5 when displaying data on a CRT.

(Prior Art) Conventionally, when color data is displayed on a monochrome CRT, only the luminance signal component is displayed, and there is no method for conveying color information to an operator.

(Problems to be Solved by the Invention) The above-described conventional system has the drawbacks that when color data is displayed on a monochrome CRT, color specification of data, abnormal termination due to commands, and color identification are impossible.

An object of the present invention is to eliminate the above drawbacks by storing color information in order to allocate each data after determining the type of CRT, selecting a color compatible pattern, and displaying the pattern by performing pattern conversion. , a monochrome CR configured so that color information can also be conveyed to the operator.
(Means for solving the problem) The color data display method of a monochrome CRT according to the present invention includes a CRT type detection section, a display data creation section, a pattern selection section, The device is configured to include a /Ctern conversion section, a pattern generation section, and a display section.

The CR, T type detection section is for determining whether the CR, T used for display is color or monochrome.

The display data creation section is for assigning and storing color information to each data.

The pattern selection section is for selecting a color corresponding pattern corresponding to a monochrome CRT.

The pattern converter is for converting the selected color corresponding pattern into a display pattern.

The pattern generating section is for generating a pattern based on the display pattern.

The display section is for displaying the generated pattern.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a monochrome CB, TO color data display method according to the present invention. 1st
In the figure, 1 is a display data creation section, 2 is a CRT type detection section, 3 is a switch, 4 is a pattern selection section, 5 is a pattern conversion section, 6 is a pattern generation section, and 7 is a display section.

The data created by the display data creation section 1 is stored using a data allocation power 2-storage table as shown in FIG. 2 in order to allocate and store color information to each data.

Data position 8 is stored on the left side of the table shown in FIG. 2, and K specified color 9 on the right side is stored. These data are sent from the display data creation section 1 to the switch 3.

In the case of a color CRT, the CRT's detecting section 2 also switches the switch 3 to the display section 7 and sends out the data in accordance with the sent CRTiC data. However, in the case of a monochrome CRT, data is sent to the pattern selection section 4 by switching the switch 3.

Data regarding the CRT is sent from the display section 7 to the CRT type detection section 2, and data representing the type of CRT (color/monochrome) detected by the CRT type discrimination means is sent from the CR/T type detection section 2 to the switch 3. It will be sent to you.

In the case of a monochrome CRT, a corresponding pattern is selected based on the data sent to the pattern selection section 4 using a color correspondence butter 7 selection table as shown in FIG.

That is, nine turns are selected based on the designated color 9, the selected color 10, and the selected pattern 11. The selected pattern is sent to the /<turn converter 5. The pattern converter 5 converts the selected pattern 12 into a display pattern l3 using the pattern conversion table shown in FIG.
strange. exchange. The converted pattern is sent to the no-no-turn generating section 6. Here, a pattern is generated according to the display pattern 13 and sent to the display section 7. Display section 7
Now let's demonstrate this pattern.

On the other hand, in the case of a color CRT, data is sent directly from the switch 3 to the display section 7, and a color image is displayed on the display section 7.

(Effects of the Invention) As explained above, the present invention enables color data to be displayed on a monochrome CRT, thereby preventing abnormal termination of programs and inability to distinguish colors, and allowing the same program to display color data on a color CRT. , or monochrome C
There is an advantage that it can be displayed in the same way on RT.
