Abstract
An image pickup apparatus which includes a timing pulse generator, an imager having an effective pixel number requiring a predetermined frequency for the horizontal scanning pulse in order to to produce a video signal having a normal aspect ratio and a video signal processing circuit for processing the signal outputted from the imager to generating a video signal. An electronic zoom signal processing circuit is provided for enlarging the video signal generated by the video signal processing circuit in the horizontal direction. The timing pulse generator supplies the imager with a horizontal pulse having a frequency higher than the predetermined frequency required by the effective pixel number of the image input element and the electronic zoom signal processing circuit enlarges the video signal generated in the horizontal direction to produce a video signal having a normal aspect ratio.
