摘要：We are studying an intelligent robot camera that can shoot automatically as well as a human broadcast cameraman can. To elucidate a cameraman's zooming techniques, we recently examined our measurement methods and conducted a basic experiment while shooting still subjects. The results showed that our measurement methods were effective in faithfully gauging zooming characteristics. Furthermore, analyses of zooming actions revealed that, in the case of repeated shooting of the same scene, the velocity of the operating rod always followed almost the same shaped zooming velocity curve, and that the rates of size change of the subject for normalized zooming times were 0.62-0.91 (second half) in the zooming-in operation and 0.17-0.44 (first half) in the zooming-out operation.
