Sensing of Feeling and "Kansei". Analysis of the Work and Eye Movement of Broadcasting-Studio Cameramen.

摘要

There is a rising demand for intelligent robot cameras capable of shooting dynamic pictures like those taken by professional broadcasting studio cameramen. To develop thes cameras, we devised a system for analysing the actual movements of broadcasting-studio cameramen. We conducted experiments by using programs shot in our studio.From the experiment, we found that cameramen routinely move their eyes in a range of about ±20 degrees horizontally and±15 degrees vertically before they start shooting, and they often look through the view-finder at the script to focus. We also found that the panning-speed curve is asymmetrical : quick acceleration is followed by slow deceleration. The deceleration time is 60% longer than the acceleration time, and the maximum acceleration during panning is approximately 200 deg/sec2.
