Researchers of oriental color ink painting have concentrated on physical models such as brushes; papers, and ink diffusion. These models can be efjective when painter depict a painting by tablet pen. Abstraction is main notion of oriental color ink painting. More than thousand years, oriental color ink painter uses this notion, for representing their feelings. lf a painter has poor skill to use tablet pen or drawing ability; result should be not satisfied. In this paper, we propose an interactive painting method for oriental color ink painting. We use a computational approach to abstract landscape image and reproduce a painting by oriental color ink painting method. The reason why we use landscape image, landscape painting is a major theme of oriental ink painting.
