ABSTRACT:
In an apparatus for producing video signals in which a memory storing color data is addressed with an address signal determined by video data to produce color data, an analog RGB signal producing circuit in which the color data read from the memory are converted to analog signals is provided so that a color image can be displayed on a CRT or an exclusively used monitor means to which the color data are directly supplied. Further, a signal conversion circuit, a video color signal producing circuit and a composite circuit are provided wherein a luminance signal and color difference signals are produced in accordance with the color data in the signal conversion circuit, and the luminance signal is converted to an analog luminance signal and color carriers are produced by modulating analog signals converted from the color difference signals with the color subcarriers in the video color signal producing circuit. In the composite circuit, the analog luminance signal, the color carriers and a burst signal obtained in accordance with the color subcarriers are combined to produce a composite signal so that a color image can be displayed on a CRT to which the composite signal is supplied through a receiving circuit of a television set.
