Abstract:
A video timing generator for video cameras requiring control and timing signals at multiple predetermined event times during a video scan, the timing generator comprising:a count generator producing a sequence of current count values at event times;an event memory holding operation codes associated with target count values;programming means for programming multiple target count values in the event memory corresponding to the predetermined event times and associated with operation codes for control and timing signals at the multiple predetermined event times;a scanning circuit scanning through the event memory in between event times to sequentially read-out all of the target count values after each event time;a comparator receiving at each given event time, in sequence, the read-out target count values and comparing them to a count value of the given event time;a decoder reading and executing an operation code from the event memory corresponding to read-out target count values matching the given event time as indicated by the comparator to produce at least one control and timing signal.
