Abstract

An image display system comprising display means (3) for displaying a series of images (2) along the path of a vehicle; lighting (19) for briefly illuminating individual images (2); a plurality of detectors (8,9) arranged to output measurements of the speed of a passing vehicle; and a control unit (6) arranged to control the lighting to illuminate images successively as the vehicle passes at illumination timings based on speed measurements from the plurality of detectors. The control unit (6) is arranged to apply a systematic correction to the speed measurements from the detectors (8,9) based on a statistical analysis of the speed measurements from all the detectors (8,9), which can reduce drift and jitter. The control unit (6) includes a dynamics processing unit (50) arranged to perform non-linear predictive filtering of the speed measurements to produce an instantaneous estimate of the vehicle speed. The control unit (6) also includes a timing generator (60) operating asynchronously of the dynamics processing unit (50) and arranged to derive the illumination timings from the instantaneous speed estimate.
