A digital video tape recorder. A clock is extracted from the horizontal sync signal within the luminance signal, and used in processing the luminance portion of the video signal. A clock is also extracted from a color burst within the chrominance signal and is used for processing the chrominance portion. The chrominance portion of the video signal to be recorded is converted to a low frequency band before recording. During playback, the reverse of this operation is performed, thereby producing a signal with the original color frequency.

Magnetic recording and reproducing apparatus obtaining separate clock

An imaging device such as a video camera having a viewfinder for displaying an imaging signal to the photographer which indicates the degree of hand wobble (i.e., movement of the camera by the photographer). A hand wobble display circuit generates this imaging signal for the viewfinder by generating a field-difference or a frame-difference signal of the electronic viewfinder signal and displaying the difference signal on the viewfinder. The magnitude of the difference signal can be used to determine the degree of hand wobble.
