• In this letter we propose a new visual secret sharing scheme (VSSS) applicable to color images containing many colors such as photographs. In the proposed VSSS we can perceive a concealed secret image appearing on a reproduced image, which is obtained by stacking certain shares, according to the principle called the meanvalue-color mixing (MCM). First, we mathematically formulate the MCM and define a new parameter that determines the minimum quality of the reproduced secret image. Then, we explicitly construct the VSSS based on the MCM under general access structures. The construction is proved to be realistic by experiment under the (2,2)-threshold access structure.
