- W4378447907 abstract "The advance in imaging system of digital camera and display are remarkable recently. One of important factors of the imaging system is pixel number of camera area sensor and display. The pixel number of digital camera such as 36MPixels (D800, Nikon corp.) has been on the market, and in some cameras, low pass filter is removed for high resolution. Concerning display, 4 K display (3840×2160 pixels) is already on market, and 8K display (7680×4320 pixels) is planned to sell in near future.It is recognized that the image quality increases according to the increase of the pixel number of input and output devices. Image quality has controlled by various factors such as color, sharpness, gradation, depth feeling, texture feeling and so on. From the view point of resolution, the studies on the effect are not enough. In this report, to understand the effect of resolution to hardcopy and softcopy, concerning perspective image, image quality in general and depth feeling, and concerning the still life image, image quality in general and texture feeling are subjectively investigated respectively.Softcopy of 4 K display is used. Concerning the pixel number, image data of 3840 × 2160pixel (which is named 4K), 1920 × 1080pixel (2K), 960 × 480 pixel (1K) and 480 × 240 pixel (0.5K) are prepared and subjectively estimated. Hardcopy is also nearly same data are prepared. Image quality, depth feeling and texture feeling increases as pixel number increase on the whole." @default.
