Video camera system which multiplexes internal, external, and sensing
parameters onto the video signal in order to identify individual
segments
Abstract:
A video camera system has a recording portion and a reproducing portion. The recording portion includes an imaging device for imaging a subject and for generating a video signal, a parameter generator for generating parameters for imaging the subject, a parameter collector for collecting the parameters, a multiplexer for multiplexing the video signal with the parameters and for generating a multiplexed signal, and a recorder for recording the multiplexed signal on a tape. The reproducing portion includes a reproducer for reproducing the multiplex signal from the tape, a separator for separating the multiplexed signal into the video signal and the parameters, a condition detector for detecting a moment when the parameters are set in a predetermined condition, and for producing a condition detected signal, a image reducer for reducing a size of the video signal and for generating a reduced video signal, and a memory for storing the reduced video signal in response to the condition detected signal. In the memory multiple images obtained from different frames are stored for displaying the multiple image.
