Abstract:
An event recording camera system for forming a time sequence of images, comprising:A. a first digital camera which generates a first sequence of digital image frames, each frame of said first sequence representing a first view that is captured by said first digital camera at a first moment in time and imaged onto a first array of detector elements; B. a second digital camera which generates a second sequence of digital image frames, each frame of said second sequence representing a second view that is captured by said second digital camera at a second moment in time and imaged onto a second array of detector elements; C. a precision timer associated with said first digital camera, and a timer processing means which marks frames of said first sequence of digital image frames with a time reference indicative of said first moment in time, D. a tunable timer in said second digital camera, said tunable timer being operative in at least a faster mode and in a slower mode, and timer processing means which marks frames of said second sequence with a time reference representative of said second moment in time as determined by the tunable timer; and E. mode selection means for accessing the precision timer and selecting a mode having a speed to maintain said tunable timer synchronous with said precision timer, so that said first and second sequences of digital image frames are marked with a common time reference.
