Information about camera operating such as zoom, focus, pan, tilt and tracking is useful not only for efficient video coding, but also for content-based video representation. A camera operating parameter measurement system designed specifically for these applications is therefore developed.This system, implemented in real time and synchronized with the video signal, measures the precise camera operating parameters.We calibrated the camera lens using a camera model that accounts for radial lens distortion.The system is then applied to infer image motion from pan and tilt operating parameters.The experimental results show that the inferred motion coincides with the actual motion very well, with an error of less than 0.5 pixel even for large motion up to 80 pixels.
