Abstract: I researched a influence that Resolution of video image of portable terminal gives evaluate person.
The senior of martial arts saw the image of a basic type, and evaluated the movement technology. It was examined whether
the evaluation was different when the resolution was paid to attention in that case, and the resolution was changed and thesame image was inspected. The senior of martial arts saw the image of a basic type, and evaluated the movement technology.
It was examined whether the evaluation was different when the resolution was paid to attention in that case, and theresolution was changed and the same image was inspected. It was subjectively evaluated whether it seemed to be able to use
the image to guide athletic skills by five stages. As a result, it has been understood that there are a lot of people who thinkthat it can evaluate athletic skills by the resolution of 320*240.

However, it has been understood that it is interesting fromthe result of the experiment actually.

If the resolution of resolution D(320*240) or more is used,
it has been understood that the possibility that athletic skillsof the extent that can be examined can be evaluated is high.

Cellular phones of DoCoMo marketed in Japan are 27models (As of April, 2010). The cellular phone with theresolution of 320*240 or more is 28 (96%). Thus, themovie filming feature of a lot of cellular phones fills thisstandard.
