Abstract
A stereo still video camera includes two image sensors for generating a pair of video signals corresponding to left and right stereoscopic images as would be seen by a human observer. By recording the video signals as separate fields on concentric tracks on a rotating video disk, the stereo recording is effected with minimal disruption of the existing still video (non-stereo) standard. The pair of video signals are sequentially processed and separately recorded in synchronism with a phase signal derived from the periodic rotation of the disk. The phase signal is similarly used to synchronize the playback of the recorded video signals with a stereo display device.
Claims4
A still video camera for recording a stereo image of a subject on a video disk as separate video fields, said video disk including a phase indicator in a hub region thereof for defining the beginning of a field relative to a track on the disk;
- said still video camera comprising:
- a first image sensor for sensing the subject and generating a first video signal corresponding to the first field of the image;
- a second image sensor for sensing the subject and generating a second video signal corresponding to the second field of the image, said second sensor displaced from said first sensor by a distance corresponding to the interocular separation of a human observer in order to produce a stereo effect in the respective video signals;
- means for simultaneously exposing said first and second image sensors to the subject, thereby producing simultaneously-exposed first and second still video signals;
- signal processing means for generating respective first and second recording signals from said first and second still video signals, said first recording signal corresponding to the first field of the image and said second recording signal corresponding to the second field of the image;
- means for rotating the video disk;
- means for sensing the phase indicator on the rotating video disk and generating a phase signal therefrom;
- first recording means for recording the first recording signal on a first circular track on the video disk;
- second recording means for recording the second video signal on a second circular track that is concentric to said first track on the same disk side thereof;
- and
- timing means responsive to the occurrence of said phase signal for applying said first and second recording signals to said first and second recording means to record said first and second video fields in concentric tracks as a stereo field pair.
