In relation to the recent development of ultra high definition imaging technique (4K)<br> that have quadruple amount of pixels relative to high definition imaging (HD), it has<br> been reported that observer's subjective impression differ between these imaging. The<br> present study examined how differences in resolution (4K and HD imaging) influence<br> subjective impressions of movies in association with movie contents (natural/artificial<br> objects) and fields of view (wide/medium/narrow) (Exp1). We also investigated the<br> effects of the quantities of motion on subjective impressions of movies in different im-<br>ge resolutions with the flame rate higher (59.94 fps) than the previous study (23.98<br> fps) (Exp2). We found that 4K movies, as compared to HD movies, induced stronger<br> impressions regarding evaluation and comfort especially when they were presented with<br> natural scene and/or larger field of view. It was also shown that 4K movies with higher<br> flame rate induced stronger impressions regarding desirability and comfort regardless<br> of motion quantities, contrary to the previous finding that 4K movies with the larger<br> quantities of motion gave observer lower impression regarding desirability and comfort<br> than HD movies. These results demonstrate that the differences in image resolution<br> could modulate subjective impressions of movies in accordance with the differences in<br> movie contents, fields of view, and flame rate. Moreover, the current findings suggest<br> that there exist some desirable conditions under which the ultra high definition imaging<br> could effectively enhance observers' subjective impressions of movies.<br>
