Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we present the relationship between the characteristic quantities of tree-drawing test and the depression scale. Tree-drawing test, in which patients draw a picture of tree with nuts, has often been used in psychosomatic internal medicine as a conventional psychological test, and this test is useful to examine their mental state. Fractal analysis of patient’s picture is effective because it is composed by curves. We analyzed their pictures by an image processing method, and calculated the characteristic quantities (fractal dimension and drawing volume). We also examined their depression scale and found the correlation between those indices and depression scale.
