ABSTRACT:
An output apparatus for image signals includes an image signal processing circuit for providing a digital luminance signal, a digital color signal, a digital composite video signal etc., a multiplexing circuit for multiplexing these signals to be positioned alternately on a time axis, a D/A converter for converting the digital multiplexed signal to an analog multiplexed signal, and plural signal holding circuits for an analog luminance signal, an analog color signal, an analog composite video signal etc. separated from the analog multiplexed signal, respectively. Therefore, only one D/A converter is used therein, so that the cost is decreased and the size becomes small.
