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

Auditory information plays an integral role in AV media because even identical images are perceived differently when they are matched with different music. However, we now present the results of experiments in which the changes in subjective perceptions were analyzed on the basis of the physical properties of the perceived items. The purpose of this study is to investigate the effects of music on image impressions in terms of the physical properties of images. 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. Second, to clarify the relationship between the impressions of images or music and the physical properties, we compare the different image or music perceptions with each other and also compare their respective physical properties, which include color information, structural information, and frequency characteristics. The color information of an image containing green or saturation colors and the power of the music are found to be strongly correlated with adjectives expressing potency and activity. The entropy of saturation is found to be correlated with words expressing spatial extent.
