A recording/reproducing apparatus for outputting a video achieving high resolution thereupon, while suppressing an amount of data to be recorded onto a recording medium, comprises an input unit for inputting a video signal therein, a recording medium for recording the video signal inputted, a recording/reproducing processor unit for conducting signal processing for reproducing the video signal from the recording medium and an operation control of that recording medium, an exchanger for providing an output with switching between the video signal from the input unit and the signal from the recording/reproducing processor unit, and a resolution conversion unit for producing the video signal with increasing the pixel number of the video from the exchanger.
