Visual field monitoring and processing system - uses video camera and computer to produce false colour rendering of black and white picture

摘要

The appts. is used for monitoring a visual field or for examination of a photograph. The photograph or visual scene is projected onto the screen or target element of a video camera by an optical system and is translated into a series of voltages which may be fed to a computer. The photograph or scene is in effect broken up into a raster of many points. The computer may convert black and white contrast differences into different colours to be shown on the screen of a colour TV set. The results may be recorded as a colour photograph. The system may be used with moving objects, e.g. a traffic scene in which an accident has occurred.
