YIQ Computer graphics system

Abstract: A YIQ computer graphics system includes a data processing system having a data tablet for receiving inputs from an artist and a video processing system connected to the data processing system. The video processing system includes a two component expandable frame store with the first component storing video intensity information for each pixel of a visual image and with the second component storing two video color components each for one-half of the visual image. The video processing system further includes a memory controller coupled to receive pixel address information identifying pixel locations within a row and column matrix of pixel locations containing the visual image and addressing specific locations within the frame store in response thereto, an interface circuit coupled to transfer video data between the frame store and the data processing system at pixel locations within a matrix of locations defined by the data processing system, and a video output processor coupled to provide matrix address locations to the frame store and receive in return video data from the frame store to generate a color video output signal in raster scan order. The video processing system may also include an input scanner coupled to write into the frame store video information on a continuous frame-by-frame basis to permit the video output processor to output a video signal which indicates a continuously changing video image on a frame-by-frame real time basis.

Video data acquisition system and hand-held application module for operation thereof

Abstract: A video data acquisition system includes a vision system having a video camera for taking pictures of articles. The video acquisition system is adapted to acquire, digitize and select signals within a predetermined amplitude range as representations of pixels of the images of the pictures arranged in rows, columns and diagonal lines, and further adapted to provide a total count of pixels in rows, columns and diagonal lines. A hand-held application module for directing the operation of the vision system has teaching capabilities in conjunction with the system for causing the video camera to take repeated pictures of an article within its field of view in various positions to provide identity of the article. The video acquisition system includes means for computing the area and perimeter of the article and for computing the maximum moments and minimum moments, thereby providing an identification of the article and its orientation.

Video game collision detection system

Abstract: A video game includes a pre-recorded video signal depicting selected objects upon a background; e.g., a race track where the selected objects are colored racing cars, the color being used to distinguish the cars from their background. An associated video game unit with manual player controls generates a manually actuated object and collisions are indicated by sensing the time coincident signals of the selected object and the manually actuated object.

A Microprocessor CCTV Conitroller for Safeguards Applications

Abstract: An integral part of a state of the art Alarm Display and Assessment System is the closed circuit television (CCTV) subsystem. It is in this portion of the system where all video signals are switched, recorded, and replayed for surveillance and assessment purposes. This paper presents the implementation of one such CCTV subsystem. This implementation incorporates two Motorola H6809 microprocessors as video controllers that collectively have the capability of initiating the recording of multiple "alarm" scenes, switching any live or recorded video from any camera to any one of the assessment monitors, annotating or identifying all video scenes, verifying the presence of video on all cameras, and reporting critical component failures to a "host" LSI-11/23 system computer. Included in this system are: a rigid video disc recorder, a video routing switcher, character generators for annotation, a video presence detector, and manual switchers.

Method for the acoustic design of video games

Abstract: The invention relates to a method for the audio design of video games which are depicted by means of combining a video game device with a monitor device, usually a television set. It is the object of the invention to improve the previously simple audio accompaniment and to design and play back the audio information in such a way that the user of a video game device is addressed not only visually, but also acoustically by the programmed events of the video game. The audio information accompanying the respective game can be called up in the video game device and stored using the frequency response and phase relations characteristic of artificial head stereophonics. The play back of said information takes place via at least one set of stereo headphones.

Video Instrumentation And Procedures For Data Analysis

Abstract: Video systems can be configured to measure position, size, attitude, brightness, and color of objects including objects in high speed events. The measurements may be time correlated or images from several sources (perhaps widely separated) may be correlated directly by image splitting techniques. The composition and specifications of the video system will vary considerably depending on the parameters measured and the accuracy desired. The basis of making the above measurements, using video, are presented in a format to guide practitioners in applying video as a measuring tool. Topics include relative vs. absolute measurements, scales and references, data insertion and retrieval, human factors, and video digitization.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.

High-Speed Color Video System For Data Acquisition At 200 Fields Per Second

Abstract: SummaryWith our national preoccupation for increased productivity with ongoing cost cutting,high speed color video surveillance in the diciplines of manufacturing, electronic assemblyand product packaging seems as natural as the application of high speed film cameras to ourearlier efforts in the Aerospace industry.High speed color video is not the panacea for everyone's optical data acquisition re-quirements, however, in the areas on non predictive failure surveillance, quick look testmonitoring or on -line problem analysis, high speed video has proven to be a highly costeffective and flexible tool for data analysis.

Human Memory Limitations in Multi-Object Tracking.

Abstract: : Basic perofrmance data were obtained on the effect of critical task variables in unaided multi-object tracking behavior. Six observers viewed computer-generated displays in which five, seven, or nine objects represented targets that moved in random linear trajectories at one of two speeds. Displayed positions were updated six times at intervals of 5, 8, 13 or 18 seconds, and no track history was provided. The task for the observer was to monitor the trajectories and then predict the next position of each object. Results showed that the unaided observer can keep track of up to about seven moving objects. Performance improved as the interval between updates was increased to about 13 seconds. These variables interact in their effects on tracking performance and may be trade off in a complex manner. A family of mathematical models of human memory that focus on the encoding, learning, and rehearsal processes of the observer was developed. Two of the models' predictions were consistent with the data observed and those reported in the psychological literature. The analysis of human memory and information processing limitations should be extended to more complex operational tasks to support system designers with quantitative estimates of operator performance.
