EXPERIMENTAL APPROACH FOR THE OPTIMUM PARAMETERS OF PREFERRED IMAGES

In order to measure the parameters of consumers' preferred image quality, this research suggests the following image quality assessment factors: 1. dynamic range, 2. color, and 3. contrast. For measuring the optimum parameter ranges of preferred images, the authors select 100 images from various Web sites by contents: portrait, landscape, and nightscape. Therefore, a total of 300 images are collected based on over 30 recommendations by appreciators. They discovered the specific ranges of preferred image quality metrics. As a result, the Digital Zone generally shows 6-10 stop ranges in portrait, nightscape, and landscape. Total RGB mean values represent in portrait, nightscape, and landscape. Total scene contrast ranges represent in portrait, nightscape, and landscape. Throughout this research, they are able to measure the preferred image quality metrics ranges. Also, they expect the practical and specific dynamic range, color, and contrast information of preferred image quality to positively influence product development.
