In Optical See-Through (OST) displays, the chroma component in color space is often distorted. OST displays appear to have a uniquely different gamut feature compared with conventional color devices. In this paper, we proposed a novel two-step gamut mapping method for OST displays. The conventional CARISMA (Color Appearance Research for Interactive System Management and Application) algorithm is extended straightforwardly, and its process is divided into two separate steps (lightness mapping and chroma compression) by reflecting the characteristics of the newtype OST. We confirmed experimentally that the proposed gamut mapping method can reduce color distortion better than the existing CARISMA.

Transparency of optical see-through head-mounted displays (OST-HMDs) makes them suffer from background blending. Existing works have tackled this problem by color correction, but have not addressed how to estimate the background color accurately. In this paper, we apply colorimetric estimation to the subtraction compensation for background blending. Moreover, we propose an optimization framework that trades-off the overall color distortion and clipping to achieve the optimal color correction, constrained to keeping image structures and details.
