Television system for the display of visuals with high resolution
First Claim
1. In a television system of the type wherein a portion of a transmitted scene is displayed by a television receiving tube with high resolution as compared with the display resolution of the entire scene by the same television receiving tube, the combination comprising:
- means for producing separate video signals corresponding to separate frames forming an array of component frames of a scene,a storage medium including independent recording means to separately record the video signal corresponding to each frame in the array of frames forming the scene,timing control means to synchronize the video signals in phase-shifted relations for separate recording by said storage medium such that a video signal corresponding to one component frame of the scene is recorded at a predetermined time-displaced relation to the recording of the video signal corresponding to a different component frame that is contiguous therewith in the scene, said timing control means including time delay means for each one of at least some of the separate video signals,means coupled to each time delay means for producing a sync phase control signal,sync generator means for applying horizontal and vertical scan control pulses to said means for producing separate video signals, andcontrol means for coupling each sync phase control signal to said sync generator means to phase shift the horizontal and vertical scan control pulses and thereby provide phase-shifted video signals corresponding to the component frames in the array forming the scene.

Abstract
In a television system, the display by a monitor forms a high resolution window-like frame that is selectively movable about a larger scene which is transmitted as an array of contiguous frames. Separate tracks on a disc-type recorder are used to store a video signal from a camera corresponding to each frame making up the array of contiguous frames in the scene. Either the camera or the scene is repositioned to view each frame in the scene. The video signals are recorded at phase-displaced relations by phase shifting the sweep waveform supplied to the camera while scanning each component of the scene. The replayed video signals corresponding to the array of contiguous frames in the scene are blanked by gates controlled by adjustable delay circuits to select a single frame of unblanked video signal for display by a monitor which corresonds to a portion of the entire scene.

-
means for producing separate video signals corresponding to separate frames forming an array of component frames of a scene, a storage medium including independent recording means to separately record the video signal corresponding to each frame in the array of frames forming the scene, timing control means to synchronize the video signals in phase-shifted relations for separate recording by said storage medium such that a video signal corresponding to one component frame of the scene is recorded at a predetermined time-displaced relation to the recording of the video signal corresponding to a different component frame that is contiguous therewith in the scene, sync generator means for producing horizontal and vertical scan control pulses, gate means for blanking out all but a single video signal frame consisting of contiguous portions of the replayed separate recordings of video signals from said storage medium, time delay circuit means for applying phase control signals to said gate means and said means for generating horizontal and vertical scan control pulses, and means coupled to said gate means and said sync generator means for combining in a synchronous relation the unblanked video signal frame received from said gate means with horizontal and vertical scan control pulses received from said sync generator. - View Dependent Claims (10, 11, 12, 13)

14. In a television system, a method for producing a high resolution display frame corresponding to a window-like portion of an entire scene, said method including the steps of:
-
generating phase-shifted synchronizing waveforms for each one of at least some of separate video signals to control the production of the separate video signals with corresponding phase-shifted relations such that the active video portions of scan lines for contiguous horizontally-arranged frames are continuous and the active video portions of scan lines for contiguous vertically-arranged frames for coincidentally timed, using the phase-shifted synchronizing waveforms to control a sync generator to produce corresponding horizontal and vertical scan control pulses, using said horizontal and vertical scan control pulses for producing separate video signals corresponding to separate frames of an array of contiguous component frames forming a scene, storing the separate video signals in their phase-shifted relation, and selecting contiguous active video portions of unblanked scan lines from the replayed stored video signals to form a single video frame for displaying a window-like portion of the entire scene. - View Dependent Claims (15)
