Abstract

The large panel display has been manufactured and highly developed based on the cutting-edge technology. Also the advanced technology released bigger displays with higher resolution like 4K UHD and curved display in these days. The picture of the large panel display has great chances for expressing factors of presence and three dimensional effects to viewers. It leads the study for hardware system in high resolution and large panel displays to improve the viewer's optimum image quality. The study on the hardware of the panel display performs in many ways and applies on the large panel products. Beyond these studies, we need to focus on the emotional image quality and realistic image quality. We focused on with the viewer's emotion toward the images rather than on the threshold of the technical image quality. We conducted image quality experiments with images that can be shown on large panel displays and appear with great impact and presence. Researching the perceived image quality assessment about the local color rendering on the large panel display can show us that the viewer's reactions to color compensation and make another way to achieve optimum image quality. Therefore, we rendered the color of local areas of interest instead of the whole picture to improve the sense of immersion due to the picture of the large panel display big enough to fill the whole viewing angle. When the objects in scenes show, viewers focus on it and the area of interest is made up spontaneously. With the color reproduction in the area of interest catching the viewer's eyes, it can change the image quality of the entire image on the display and affect the viewer's emotional image quality. We conducted and analyzed image quality assessment experiment of the local color rendered image to implement image quality with maximized presence and impact. The perceived image quality experiment with local color rendering images show us that the partial color rendering on area of interest affects the viewer's emotional image quality and makes the entire picture more realistic. We found that the images with local color rendering process increase the reality of the entire scene by magnify the color distinction between area of interest and background.
