Abstract
Abstract An apparatus for producing and recording a video signal, which comprises a signal supplying device for picking up images in a picture area having a first or second aspect ratio to supply a first pickup output signal representing images in the picture area with the first aspect ratio or a second pickup output signal representing images in the picture area with the second aspect ratio. The pickup output signal is supplied to a signal processing circuit having a first condition for processing the first pickup output signal to produce a first video signal therefrom or a second condition for processing the second pickup output signal to produce a second video signal; whereafter the first or second video signal produced by the signal processing circuit is recorded on a recording medium. An operation control device controls the signal supplying device to supply the first pickup output signal while disposing the signal processing circuit in its first condition or controls the signal supplying device to supply the second pickup output signal while disposing the signal processing circuit in its second condition.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
326 words
Apparatus for producing and recording a video signal comprising: image pickup means for picking up images in a picture area having one of first and second aspect ratios and driving means for driving said image pickup means with first and second sets of horizontal and vertical drive pulses for selectively supplying a first pickup output signal representing images in the picture area of the first aspect ratio or a second pickup output signal representing images in the picture area of the second aspect ratio, signal processing means having a first condition for processing the first pickup signal to produce a first video signal for recording and a second condition for processing the second pickup output signal to produce a second video signal for recording, recording means for recording on a record medium the first or second video signal produced by said signal processing means, said recording means comprising a first recording head for recording all of the first video signal when said signal processing means is placed in said first condition and a first portion of said second video signal representing substantially the same video information as said first video signal when said signal processing means is placed in said second condition, and a second recording head for recording a second portion of said second video signal representing video information other than that represented by said first portion, and operation control means coupled to said image means for selectively controlling said image pickup means to supply the first pickup output signal and for placing said signal processing means in said first condition to process said first pickup output signal when said image pickup means supplies said first pickup output signal, said operation control means also selectively controlling said image pickup means to supply the second pickup output signal and placing said signal processing means in said second condition to process said second pickup output signal when said image pickup means supplies said second pickup output signal.
