Chroma Enhancement Method Simultaneously Considering Property of Brightness Perception and Gamut Problem
Jintao Yan, Shi Bao, Go Tanaka (Nagoya City Univ.) SIS2014-65
Abstract (in Japanese) (See Japanese page) 
(in English) Hue, chroma, and lightness are three components of colors. A chroma enhancement method is proposed in this report. In the proposed method, input hues are preserved to keep the impression of the input image. On the other hand, the Helmholtz-Kohlrausch (H-K) effect is known. According to it, perceived lightness is increased when only chroma is increased. In this report, we propose a chroma enhancement method which preserves perceived lightness by considering the H-K effect. The proposed color conversion is carried out in the HSL color space and it guarantees that converted colors are proper ones to digital color images.
