【Example】

 FIG. 1 is a detailed configuration diagram of an embodiment of the present invention.

In the figure, reference numerals 1 and 2 denote a waveform display circuit which converts an electric signal of each of a plurality of input waveforms into a signal for display. Here, it is assumed that there are two input waveform signals. Reference numeral 3 is a character display circuit, which displays characters necessary for displaying the input waveform. Reference numeral 4 denotes a scale display circuit, which displays the scale necessary for displaying the input waveform. Reference numeral 5 denotes a video synthesizing circuit, which inputs signals from the waveform display circuits 1 and 2, the character display circuit 3, and the scale display circuit 4 and synthesizes them to synthesize one screen display screen. Reference numeral 6 denotes a video monitor, which displays a signal from the video synthesizing circuit 5. Reference numeral 7 is a color setting means for setting the color of each display circuit close to R, G, B. These are constituted by the logical sum of the respective signals from the respective display circuits 1, 2, 3, 4 and the signals designating the colors of R, G, B. A color video synthesizing circuit 8 synthesizes a color screen by inputting a plurality of signals from the color setting means 7 and synthesizing them. Here, R, G, B indicate the three primary color signals used in component transmission.

The operation of such a configuration will be described. The display circuits 1 to 4 convert the first input waveform, the second input waveform, characters and scale into a video signal. As shown in FIG. 1, the three primary color signals R ₁ to ₄ , G ₁ to ₄ , and B ₁ to ₄ given from the CPU or the like are ANDed, and thus the signals from the display circuits 1 to 4 are respectively obtained. The color will be set. For example, if R ₁ = 1, G ₁ = 1 and B ₁ = 0, then the video signal of the first input waveform is energized yellow. In the color setting means 7, the colors of the respective signals of the display circuits 1 to 4 are energized in this way, and these are synthesized by the color video synthesizing circuit 8. Therefore, the output of the output converter of the present invention is R, G, The output is B and the color can be specified for each display circuit. That is, if the R, G, B outputs are connected to a color video printer corresponding to the R, G, B inputs, a color hard copy with a designated color is obtained. In this embodiment, each of R, G, and B has binary 3 bits, but a full-color output is also possible by using a setting circuit of 3 or more values and using a DA converter. As shown in FIG. 1, if the video generation method is separated for each display content, an interface for outputting to a high-speed color video printer with a simple structure, that is, the output conversion apparatus of the present invention. Can be realized.
