Abstract

PURPOSE:To provide an output device capable of simultaneously and accurately printing out a displayed synthetic screen of a character screen and a graphic screen to obtain a hard copy, which converts character data and image data into respective video signals, synthesizes the signals, and converts synthetic signals thus obtained into image data. CONSTITUTION:A converting part 10 comprises converters 10a-10c for performing serial-to-parallel conversion of video signals (c) synthesized by a signal-synthesizing part 3 in accordance with red, green and blue, and has the function of outputting the converted image data (e). Therefore, video signals (d) sent from the part 3 are subjected to serial-to-parallel conversion by the converters 10a- 10c, the converted signals are momentarily stored into an image buffer 8 as the image data (e) by at least one-line amount at a time, and then the stored data are printed out by a printer 9. Accordingly, the video signals (d) corresponding to the synthetic screen displayed on a display device 6 are converted into image data, which are printed out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to printing out a screen displayed on a display device, and particularly to an output device that can simultaneously print out a composite display of a character screen and a graphic screen.

In recent years, in addition to displaying characters such as letters and symbols on the screens of various computers and input/output devices, graphic ink output such as figures has become popular. It is also being combined and displayed.

The character screen and the graph ink screen can each be printed out individually as a hard copy, but since it is not possible to simultaneously print out a hard copy of the combined screen, there is a method for printing out this combined screen display. is desired.

[Conventional technology]

FIG. 2 shows a control block diagram for displaying a character screen and a graph ink screen, and the character screen data input from the outside and stored in the memory 1 as a character code is transferred to a character generator (hereinafter referred to as CG) 2a and a converter. 2
The signal is sent to a converter 2 equipped with a video signal a, converted into image data corresponding to the character code by a CG 2a, and colored by a converter 2b, and sent to a signal synthesizer 3 as a video signal a. When the character screen is displayed alone, it is sent as is to the display 6 and displayed.

In addition, the graphics stored as image data in the memory 4 as a bitmap by external input, the screen is red, green,
The signal is sent to a converting section 5 equipped with converters 5a to 5c corresponding to the three colors of blue, subjected to parallel/serial conversion, colorized, and sent to a signal synthesizing section 3 as a video signal. When the graph ink screen is displayed alone, it is sent as is to the display 6 and displayed.

When a character screen and a graph ink screen are combined and displayed, video signals a and b are combined in a signal combining section 3 to produce a combined signal C.
The image is sent to the Rusk Scan type display 6 and displayed as a composite screen.

Also, when printing out the character display screen independently, use memory 1.
The character code data is sent out and converted into image data corresponding to the character code by C60 on the printer side, and after temporarily storing at least one line of image data in the image buffer 8, it is printed out by the printer 9.

When printing out the graph ink display screen independently, the image data output from memory 3 is transferred to image buffer 8.
At least one line of image data is temporarily stored and then printed out.

Although it is easy to print out a character screen or a graph ink screen independently in this way, there has been no method of printing out a composite display screen at the same time.

(Problems to be Solved by the Invention) Although there is no method for printing out the composite screen displayed on the display 7 as described above, the display of a graph ink screen compositely on a character screen is increasing more and more. As a result, there is a tendency for the demand for printout to increase further, and a method to solve this problem is desired.

[Means for solving problems]

The present invention provides an output device capable of simultaneously printing out a composite screen of a character screen and a graph ink screen, and is an output device equipped with a conversion means for converting a composite signal into image data. The above problems can be solved.

[Effect]

In contrast to the conventional method in which a character screen and a graph ink screen could only be printed out separately, the present invention provides a conversion means for converting a composite signal displayed on the screen into image data, and the image data converted by this conversion means. By printing out , it becomes possible to print out the composite screen.

〔Example〕

An embodiment of the present invention will be described below with reference to the control block diagram of FIG. The same symbols as in FIG. 2 indicate the same objects.

In FIG. 1, reference numeral 10 denotes a conversion unit, which converts the video signal C synthesized by the signal synthesis unit 3 into serial/parallel conversion (hereinafter referred to as S/P conversion) corresponding to each color of red, green, and blue. 10c, and has a function of sending out the converted image data e.

With such a configuration and function, the video signal d sent from the signal synthesis section 3 is horizontally synchronized.

Converter 1 of converter 10 while synchronizing with vertical synchronization
0 a"l Oc T:S/P conversion is performed, and the image data e is temporarily stored in the image buffer 8 for at least one line, and then printed out by the printer 10.

In this way, the same video signal d as the composite screen displayed on the display 6 is converted into image data, and the character screen and the graphic screen can be printed out simultaneously and accurately.

Furthermore, it goes without saying that when a character screen or a graph ink screen is displayed individually on a screen and is printed out, the video signal from the signal synthesizing section 3 can be similarly converted and printed out.

〔Effect of the invention〕

As explained above, according to the present invention, there is an effect that a composite screen display of a character screen and a graph ink screen can be simultaneously and accurately printed out to obtain a hard copy.
