A computer-controlled system was developed which provides the capability to generate processed dynamic imagery for human factors research. Processing of the video may involve any operation such as enhancing, degrading, or adding overlays. This system may also be used during experimental trials to perform data collection and score subject responses. The system is comprised of several components: a computer, an image processor, two lapse video cassette recorders, and a custom built VCR control circuit. When possible, processing is performed as the video is being displayed to a subject. When processing complexity is too great, the video is processed before experimentation. The input to the system is imagery on a video tape. The imagery is processed frame by frame and the results are stored on the output video tape. Processing appears to be performed in real time when this resultant tape is played at the regular speed. The flexibility and cost effectiveness of the system make it an ideal developmental tool, test-bed, and simulator for the processing of dynamic visual imagery. The hardware software for implementing the system are discussed in detail. Image processing, Computer graphics, Dynamic imagery, Video systems, Visual imagery, Human factors, Real time.
