Event recording system with digital line camera

A system for recording and displaying a time sequence of bodies crossing a plane, comprising:

• A. a first digital camera which generates a first sequence of digital image frames, each frame of said first sequence representing a first line object that is captured by said first digital camera at a first moment in time and imaged onto a first linear array of detector elements;
• B. a second digital camera means which generates a second sequence of digital image frames, each frame of said second sequence representing a second line object that is captured by said second digital camera means at a second moment in time and imaged onto a second linear array of detector elements;
• C. an image timer in communication with said first digital camera and with said second digital camera means, including a timer processing means which marks each frame of said first and second sequence of digital image frames with a time reference indicative of said first and second moments in time, said image timer further including a first buffer adapted to store said first sequence of digital data frames generated from said first digital camera, said image timer further including a second buffer adapted to store said second sequence of digital data frames generated from said second digital camera means;
• and
• D. a main control computer in communication with said image timer, including an internal memory which stores the frames from said first and second buffers into blocks of information, and a virtual memory subsystem in memory communication with said main control computer, said virtual memory subsystem being adapted for storage of said blocks of information, said main control computer further including a display monitor, which displays a portion of said first and second sequence as a time-sequential scene, said main control computer arranged for controlling the operation of said system and responding to commands input by a user wherein said user can selectively command the display of said time-sequential scene of said bodies crossing said plane as captured by said first digital camera and said second digital camera means.
