要約(英語): In recent years, the development of high resolution imagery has also covered digital terrestrial broadcasting, as well as mobile devices like smart phones and tablets. People have easier access to a huge selection of digital images on an increasingly large variety of devices. In order to provide attractive content, it is important to design and manage services based on users' Quality of Experience (QoE). The most effective method of evaluating QoE so far is subjective evaluation. In recent years, researchers in the field have been increasingly focusing on the biological information approach. In this paper we examine the relationship between the change in the amount of blood in frontal lobe of the brain and the preference of images by using Near-Infrared Spectroscopy (NIRS). We first measured the change in the amount of blood in the frontal lobe by NIRS while images were shown to subjects. Then performed a subjective assessment test through questionnaires, in order to get the level of preference for each image. We found that channel 6, 7, 8 and channel 10 belong to prefrontal cortex is highly relevant to human preferences of images and would allow us to indicate these preferences, and the amount of blood in prefrontal cortex changed more when subjects were observing image they liked more.
