摘要： A video camera capable of switching an aspect ratio and an electronic view finder for use in the same. In response to a switching control signal from an aspect ratio switching circuit, a video signal having a different degree of horizontal compression and an aspect switching control signal are fed to the view finder, a magnetic recording/reproducing circuit and an external device. The magnetic recording/reproducing circuit simultaneously records the video signal and the switching control signal. In reproduction, the magnetic recording/reproducing circuit reproduces and outputs the recorded switching control signal. In response to the switching control signal, the external device changes the deflection angle of a built-in display circuit and switches the aspect ratio to display the video signal. The electronic view finder receives a video signal having a different horizontal compression degree, and at the same time receives the aspect ratio switching control signal to operate the switching circuit in the view finder to change the deflection angle and hence switch the aspect ratio to display the image.
