Effects of music on image impression and relationship between impression and physical feature

Auditory information plays an integral role in AV media because even identical images are perceived differently when they are matched with different music. We now present a few studies in which the changes in subjective impressions of when visual information is matched with auditory information were analyzed on the basis of the physical features of the perceived items. The purpose of this study is to investigate the effects of music on image impressions in terms of the physical features of images or music. In this paper, we first elucidate the changes in subjective impressions when the image is presented by itself and when it is presented with music. Secondly, to clarify the relationship between the impression and physical features, we compare their respective physical features, which include color information, structural information, and frequency characteristics with subjective impressions. As a result, the color information of an image containing green or saturation colors and the power of the music were strongly correlated with adjectives expressing activity. Moreover, the entropy of saturation correlated with words expressing spatial extent.
