<P>PROBLEM TO BE SOLVED: To provide a camera device and an IEEE1394 camera system including a random trigger function by a software trigger system capable of achieving a trigger function with high time accuracy while maintaining the connection easiness of the software trigger system. <P>SOLUTION: An adder 121 provided in a trigger delay control circuit 12 adds the fixed delay value 203 in clock units transmitted by a CPU 16 to the time stamp information 202 in clock units acquired by a software trigger detection circuit 114, and outputs a time stamp 204 including the trigger delay of the fixed time. A comparator 122 compares a cycle timer value 201 output from a cycle timer operation circuit 113 with the time stamp 204 including the trigger delay of the fixed time output from the adder 121, and when the cycle timer value 201 exceeds the time stamp 204 including the trigger delay of the fixed time, sends out a trigger signal 205 instructing exposure start to a synchronizing signal generation circuit 13. <P>COPYRIGHT: (C)2011,JPO&INPIT |
