Glossary

Plain-language definitions for the most important terms.

  1. Photo finish: A timing method that creates visual evidence at the finish line so officials can decide close results from an image.
  2. Finish-line slice: The narrow line the camera records again and again. In the final image, this slice becomes a timeline.
  3. Line-scan camera: A camera that records one line repeatedly instead of taking normal full-frame pictures.
  4. Line rate: How many line slices the camera captures per second.
  5. Line speed: How quickly the subject moves through the finish line image. Faster subjects need settings that keep the evidence readable.
  6. Trigger: A signal or action that starts recording or marks an important race moment.
  7. Start recording: The operator or system begins capturing finish-line evidence.
  8. Stop recording: The operator or system ends the active recording after the relevant race moment has been captured.
  9. Automatic trigger: A signal from another device or event that starts, marks, or controls recording without the operator pressing a button.
  10. Operator trigger: A button or operator action used when a person controls the recording moment directly.
  11. RAW evidence: Original captured data before export or presentation changes.
  12. Review image: The image an operator inspects to confirm the result.
  13. Export: A saved image or file shared after review.
  14. Backup recording: Extra recording that helps recover evidence if a trigger or race moment is missed.
  15. Non-destructive review: Review that allows zoom, brightness, markers, or other viewing changes without replacing the original evidence.
