Abstract
A system for recording and displaying a time-sequential scene on a computer comprising a digital camera, an image timer, and a main control computer. The digital camera transmits a sequence of digital image frames to the timer representative of the image of a body passing a plane in space. Each frame represents a line of the body, thus forming a fractional part of the scene. Once the frame reaches the image timer, it is digitally marked with a time reference and buffered into a block of information. The main control computer stores blocks of information from the image timer for a variety of processing and features available to the user. A compression system compresses a sequence of digital image frames for storage into a selected memory, preferably a virtual memory subsystem, or hard-disc drive.
