A first video signal having a first frame rate optionally settable is generated by an image pickup device, and the first video signal is memorized in a memory and outputted from the memory. A write control device controls the write of the first video signal with respect to the memory, and a read control device controls the read of the video signal with respect to the memory. The write control device writes respective first frame data constituting the first video signal in the memory in each cycle determined by the first frame rate of the first video signal. The read control device reads the first frame data as a second video signal. The second video signal is formed from sequentially arranging the first frame data in a partially duplicating manner in a standard video signal having a standard frame rate based on a determined arrangement rule. The predetermined arrangement rule is an arrangement rule employed when respective frame data constituting a video signal having a second frame rate equal to or lower than the standard frame rate are arranged in a duplicating manner in the standard video signal. In the foregoing manner, an time elongation/contraction effect on an image can be speedily and inexpensively obtained.

A pickupgenerates a video signal based on an arbitrarily set frame rate. A frame rate converterconverts a frame rate of the video signal output from the pickupinto a predetermined frame rate. Frame rate conversion information output unitsandoutput information on frame rate conversion in a manner corresponding to a video signal after the frame rate conversion.

Image pickup apparatus with frame rate conversion information output

A video signal recording apparatus with a video and audio memorizing section for temporarily memorizing an inputted video audio signal, a time code generating section for generating a time-code of said video audio signal an auxiliary information memorizing section for temporarily memorizing auxiliary information appended to said video audio signal including said time code generating a regeneration value obtained from a time code to which one frame time is added to said recorded time code when a recording starts and correcting said regeneration value for an amount of delay corresponding to a storage volume temporarily memorized in said auxiliary information (time code, metadata, CUE audio signal, and the like) memorizing section and thus obtaining a corrected time code, and thereafter sequential time codes are generated from said corrected time code though said time code generating section.

Magnetic recording/reproduction apparatus

An information recording apparatus comprising image signal processing units for processing image signals from an image taking unit for recording with respect a magnetic tape and a microcomputer for recording, when abnormality occurs in the recording with respect to the magnetic tape due to abnormality in the image signal processing units, information relating to the recording abnormality in a blank recording region of the magnetic tape together with actual time information.

Information recorder

As a pre-processing step for transmitting a timecode, a checking information is retrieved from a linear time code (LTC). A checking data is created using the retrieved checking information. The checking data is superimposed on a vertical interval time code (VITC). As a post-processing step for transmitting a timecode, meanwhile, collating information corresponding to the checking information is retrieved from the LTC. A collating data is created using the retrieved collating information. Then, the checking data is retrieved from the received VITC. The retrieved checking and collating data are collated to verify, thereby, the presence or absence of errors in the received LTC.
