Feasibility Demonstration of a Target Cuer Simulator.
Abstract
A requirement exists to 'cue' or 'highlight' specific objects or targets within a video scene, generally available on tape in the helical-scan format. Typically, this imagery would have originated in an airborne FLIR system moving at a high velocity with respect to the targets of interest, so that additional processing of the stored pictorial information dictates simultaneous slow motion reporduction, cue insertion, and rerecording. If multiple cues are needed, as is the case in studies of operator performance, this process results in a continual degradation of the video signal. Typical helical-scan machines do not provide the described capability. A novel technique, utilizing a multichannel longitudinal tape format, has been devised and demonstrated to permit all the required modes of operation with little or no degradation of the original video signal. The operation of this system depends on the separation of the composite video signal into its constituent information and timing components for recording. The signals reproduced are then available for cue synchronization, processing, and ultimate recombination into the 'cued' composite video signal. (Author)
