An imaging apparatus including an image sensing unit for converting light from an object into a video signal and outputting a video signal, and a vibration compensation unit for compensating picture vibrations of the video signal provided by the image sensing unit. Also included are a driving unit for driving a head relative to a recording medium, and a servocontrol unit for controlling a driving condition associated with the driving unit. A control unit is also included to control an output of the vibration compensation unit. The output is controlled on the basis of an error signal of the servocontrol unit.

1. Field of the Invention
The present invention relates to a recording and/or reproducing apparatus, more particularly, to an imaging apparatus or a video camera system having a function of avoiding fluctuations or vibrations of pictures contained in video signals.
2. Description of the Related Art
FIG. 1 is a block diagram showing the configuration of the main portions of a VTR incorporated with a video camera in a single device having a conventional type of vibration preventing system;
FIG. 2 is a block diagram showing the configuration of a VTR incorporated with a video camera in a single device in accordance with a first embodiment of the present invention;
FIG. 3 is a block diagram showing the configuration of a picture vibration compensation circuit of the apparatus shown in FIG. 2;
Embodiments of the present invention will now be described below with reference to the accompanying drawings.
FIG. 2 is a block diagram showing the configuration of a VTR incorporated with a video camera in a single device in accordance with a first embodiment of the present invention.
As seen in FIG. 2, light associated with an object passing through a lens (not shown) is converted to an electrical signal by an image sensing device 1 such as a CCD, and the obtained electrical signal is provided to a camera signal processor 2, where a video signal is produced based on this signal from the image sensing device 1.
