Abstract
A picture switching apparatus for executing a fade-out/fade-in processing between adjacent video recording files includes a multiplier for multiplying a decoded video data with a multiplication coefficient (1-km), a multiplier for multiplying an output data of a data output circuit with a multiplication coefficient km and a data synthesizer for summing results of multiplication from the respective multipliers. The picture switching apparatus thus constructed performs the fade-out/fade-in processing without modification of the original video data for fading processing, by controlling km at the junction between the files such that the mining ratio of the color data for fading to a decoded color data is gradually increased/decreased.
