ABSTRACT:
A video image mixing apparatus which can prevent a fluctuation of a mixed video image by a mixed video signal in the case where a playback video signal obtained by playing a recording medium in a special playing mode and a graphics video signal. When a discontinuity of the phase of a color burst signal in the playback video signal obtained by playing the recording medium is detected, the playback video signal and the graphics video signal are delayed by a predetermined time period and the delayed signals are mixed subsequently, thereby keeping the phases of chroma signals of the playback video signal and graphics video signal equal even in a special playing mode such as a still image reproducing mode or the like. In another embodiment, the mixed video signal of the playback video signal and graphics video signal is delayed by a predetermined time and is generated.
