Ultra-high definition (4K) imaging allows us to achieve considerably higher image quality than would high definition (HD) imaging. The present study examined how 4K and HD imaging could influence subjective impressions of movies differently, in association with the quantities of motion and fields of view of these movies. We found that stronger impressions regarding comfort and impact were evoked for 4K movies with smaller quantities of motion and medium field of view. Stronger perceptions of impact occurred for HD movies with larger quantities of motion and larger field of view. HD movies also gave stronger impression regarding dynamics regardless of motion quantities. Additionally, HD movies down-converted from 4K movies tended to induce higher impressions regarding evaluation and comfort in some situations. These results suggest that subjective impressions of movies are influenced by the differences in resolution images, as well as interactions between imaging types and characteristics of movie contents.
