How are the images formed? Unlike still, movie or video cameras, the photofinish camera has no shutter and there are no frames. The capture is continuous. In place of a shutter, the photofinish camera has a narrow line of sensors behind the lens, aligned on the finishline. Using a digital scan (up to 2000 times per second) the Finishlynx system continuously captures an image of the extremely narrow (approximately 5mm) strip of track, which is the finishline. In essence this is a photograph of time and whatever passes the finishline during capture becomes a part of that image. All parts (nose, tail, hooves, ears, saddle, jockey ? the lot) of all horses in the photofinish image are right on the line. . . . → Read More: Solving The Photofinish Riddle
