The key attributes that influence the image quality of a large display
This paper investigates the perceptual attributes that have a major impact on the quality of images viewed on a large plasma display panel. An experiment was conducted that included 5 perceptual attributes that might combine to form the concept of Image Quality: colourfulness, contrast, sharpness, naturalness and visual information. They were assessed using a categorical judgement method when the display was viewed with a dark surround. The 8 test images were manipulated to produce variations in the rendering of lightness, chroma and sharpness. Approximately 79,000 observations were made by 14 observers The influence of each of the 5 perceptual attributes on image quality was investigated using principal component analysis and multiple regression analysis. The results showed contrast, naturalness and colourfulness to be key factors affecting image quality.
