Abstract
A display method including the steps of: acquiring, at a first predetermined frequency, a first series of one-spatial-dimensional instant images of the finish line of a race; simultaneously acquiring a second series of two spatial-dimensional instant images of the same finish line (19) at a second predetermined frequency; forming a temporal image (10) of the photo finish type from the first series of instant images; choosing an instant (15, 22) of the temporal image (10); analysing a two-spatial-dimensional image of the second series, the image being correlated with the selected instant (15, 22) to determine at least one distance; and displaying the analysed two-dimensional image with the determined distance or distances. Also, a display system for implementing the method.
