What kind of crazy camera can distinguish a torso crossing the line?

> When the leading edge of each runner's torso crosses the line, the camera sends an electric signal to the timing console to record the time.

I believe it’s up to the judge to place the “crossing” line at the appropriate spot.

This is why you’ll see the finish times in track move a little bit from the immediate unofficial time to the final time. A computer selects which frame was the finish and then someone on the timing crew will move the “line” a bit to exactly capture the correct time. This allows for instantaneous times and then correct final times
