摘要：We are studying an intelligent robot camera system that can automatically shoot images with a powerful sense of reality. To clarify the relationship between the size of a subject, shooting velocity, and position of the subject in the image, a basic experiment was conducted on the shooting of a moving subject. The following points were clarified. The subject's position in the image seems to be more closely related to the size of the subject than its velocity ; the larger the subject and the faster it is moving, the greater the values for the distribution of the subject's position. We also found that if a subject moves outside the best position in the image, its position is not corrected immediately but the shooting continues keeping the maximum velocity of positional change within about 0.20 to 0.35. We also conducted subjective image evaluation experiments using a camera control system. This has revealed that the factors in subjective evaluation of camera work may be divided into four groups representing continuation, vividness, sensitivity, and human-warmth, and that the tested subjects were liable to feel shots, taken with techniques similar to those used by cameramen were more human-like, so they gave them relatively high evaluations.
