An image of an object is picked up by an image processing unit () to acquire an image signal of variable frame rate. An audio signal is acquired by an audio processing unit () to generate an audio signal having the number of frames caused to be in conformity with the system frame rate to generate a recording signal of recording frame rate from the image signal of the variable frame rate and an audio signal having the number of frames caused to be in conformity with the system frame rate. In recording a recording signal of the recording frame rate onto or into a recording medium () by a recording/reproducing unit (), discrimination information indicating image pick-up frame rate and system frame rate is recorded onto or into the recording medium (), e.g., as MXF (Material Exchange Format) file along with the image signal of the variable frame rate and the audio signal having the number of frames caused to be in conformity with the system frame rate.

The present invention provides a meta-data display system capable of displaying meta data related to a shot video material along with the video material synchronously to the material. The meta-data display system includes an imaging apparatus for generating a video signal representing the video material. The meta-data display system also has a meta-data synthesis apparatus for extracting at least a part of meta data from the video signal including the meta data added for every frame and synthesizing the extracted part with the video signal. The meta-data display system also includes display apparatus each used for displaying a video signal including meta data synthesized therewith. In such a configuration, a part of meta data added to a video signal is extracted and converted into video data, which is then multiplexed in the video signal of every frame. Thus, the display apparatus are each capable of displaying not only an image represented by a video signal, but also meta data related to the image synchronously with the image.

When a recording start executed in a variable-speed recording mode, at STa signal having a variable frame rate is selected on the basis of a validity signal from among image signals having a predetermined output frame rate in which the images having the variable frame rate are contained and stored in a memory. If it is decided at STthat a phase difference between a write position and a read position in the memory has reached a recording start level, the stored signal is recorded in a recording medium at ST. If it is decided at STthat the phase difference has decreased to a recording stop level, recording to the recording medium is stopped at ST. When an end operation is executed at ST, the signal in the memory is recorded in the recording medium to then end actions. The signals are selected and recorded, thus resulting in a smaller signal quantity. Further, if the variable frame rate is varied, video effects can be confirmed only by reproducing the recorded signals.

Picked up image recording system, signal recording device, and signal recording method

In order to present a video-recording system capable of managing a video material and meta data related to the video material in an integrated manner by directly linking the meta data to the video material, the video-recording system is provided with a meta data addition apparatus for adding the meta data to every frame of a video signal generated by an imaging apparatus as a video signal representing the video material and a VTR for recording the video signal including the additional meta data onto a recording medium. In such a configuration, concurrently with a shooting operation carried out by using the imaging apparatus, meta data related to a video signal generated in the shooting operation can be sequentially added to every frame of the video signal and, then, the video signal including the additional meta data can be sequentially recorded onto the recording medium. Thus, the meta data and the video signal can be recorded on the same recording medium by directly linking the meta data to the video signal so that the meta data and the video signal can be managed in an integrated manner.

A tape tension controlling circuit which eliminates a complicated controlling operation and is produced at a very low cost. A supply side tape tension regulator is provided on the supply reel side while a take-up side tape tension regulator is provided on the take-up reel side with reference to a rotary drum, and displacements of the regulators corresponding to tension values of the magnetic tape are fed back to reel controlling systems for the supply reel and the take-up reel so that the tape tension on the supply reel side and the tape tension on the take-up reel side are individually kept constant. When the magnetic tape is to be fed in a pinch-off condition wherein a pinch roller is spaced away from the magnetic tape, a take-up side tension error signal is inhibited from being supplied.
