The use of a digital image for assessing texture appearance was investigated. Since there are still limitations to reproduce texture appearance of a physical object on display devices using a digital image such as resolution, physical size and viewing distance, the influences of the changes of the conditions were examined. In the present work, we focus on coarseness of a metallic paint coating. By comparing with the scaled perceptual coarseness difference of the metallic paint coating panels with that of their reproduced images assessed in several different conditions, the results showed that the perceptual coarseness difference could be assessed from displayed images. Although the absolute coarseness appearance was difficult to be reproduced, it was found that the coarseness difference did not influenced by the slight changes of the conditions. Also, performance of the computational coarseness model  developed for predicting the perceptual coarseness from an image was verified by comparing with the perceptual coarseness obtained by the visual assessments.
