Analysis of the Camera Work of Television Cameramen while Tracking Subjects

Abstract

We analyzed the shooting technique of cameramen in relayed soccer telecast which is difficult to predict subjects'movement. We tested how cameramen confirm the subjests and how control the camera, by detecting their eye movement and velocity of the camera.
Outcomes therefrom :
·Cameramen shoot by repeatedly paying attention of approximately 50 msec at a time to thesurroundings.
·They always leave space in front of a moving subject, and the quantity of the space depends on the subject's size in the image and its velocity
·At an abrupt change in the subject's movement, sense it and perform the optimal correction in a very short time of about 300 msec.
·The maximum acceleration produced during panning was some 200 deg/sec² while on air and 300 deg/sec² while searching.
