Event recording system with digital line camera
First Claim
1. A system for recording and displaying a time sequence of bodies crossing a plane, comprising:
- A. a digital camera which generates a sequence of digital image frames, each frame of said sequence representing light values of pixels from a line object that is captured by said camera at a moment in time and imaged onto a linear array of detector elements, said digital camera producing an output signal comprising a plurality of digital words representative of said digital image frames;
B. an image timer, in communication with said digital camera, including a timer processing means which marks each frame of said sequence with a time reference indicative of said moment in time, said image timer further including a buffer adapted to store said digital image frames generated by said digital camera; and
C. a main control computer, in communication with said image timer and said digital camera, including an internal memory which stores said frames from said buffer as 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 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.

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.

33. 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. - View Dependent Claims (34, 35, 36, 37)
