Abstract

We have found that the sense of brilliant observed from an image is deteriorated by a digital processing of granular noise reduction. By seven grade subjective assessment tests about “sense of brilliant” removing and adding isolated impulsive dots, “sense of brilliant” was deteriorated “-2”(reduction) and improved “+1”(addition). We have found the more than 5.4% isolated impulsive dots of total pixel greatly generated “sense of brilliant”.
