摘要

The main purpose of this study aimed to investigate the relationship between two factors (color number and relative area) and pictorial complexity through visual search approach, and the appropriate quantification of the relationship was also concluded via complexity measure approach. The results indicated positive relationship between color number and pictorial complexity when the number of different colors used in a picture is less than 6. The increasing rate becomes graded while more than 6 colors are involved. Besides, the relationship between difference of color areas and complexity value was inverse proportion. Finally, 2 appropriate quantifications were proposed in this study: (1) (The equation is abbreviated), where (The equation is abbreviated), S the set of all elements, S(subscript i) the set of elements of i(superscript th) color. (2) (The equation is abbreviated), If i=j, then (The equation is abbreviated), If i=j then (The equation is abbreviated). S is the set of all elements，and S(subscript i) is the set of elements of i(superscript th) color. Quantification H1 focuses on describing the influence of elements to pictorial complexity, and H2 focuses on describing the influence of relationship between each pair of elements to pictorial complexity.
