Abstract
Recently the pixel number of display and digital camera image sensor increases rapidly and the image quality including depth and texture feeling expression is paid attention to. In this study, focusing on the point of their pixel number/resolution, subjective estimation of image quality dependence on the pixel number is carried out. Two types images for 4K display (3840×2160pixels) are prepared and resized to 1/4, 1/16 and 1/64. They are displayed at 4K display and subjective estimation is carried out by 25 peoples. It is obtained that the image quality increases as the pixel number increases within the range that pixel is distinguished by vision.
