Abstract(in English) In this report, we propose a simplified lightness modification algorithm for generating Craik O'Brien effect. The proposed method changes an intensity of Y component only around contours of objects in an input image. By the proposed method, it creates an optical illusion of contrast which increases visibility of dichromats with preservation of color impression of the input image. To extract contours information of object, a T-model filter is introduced which requires only a one-line-buffer memory. In addition, the proposed method generates Craik-O'Brien effect without divider and multiplier, thus, it is efficient for embedded system implementation. Through some experiments, validity of the proposed method is verified.
