In this paper, we propose a visual accessibility technique in an MPEG‐21 framework. In particular, MPEG‐21 visual accessibility for the colored‐visual resource of a digital item is proposed to give better accessibility of color information to people with color vision deficiency (CVD). We propose an adaptation system for CVD as well as a description of CVD in MPEG‐21. To verify the usefulness of the proposed method, computer simulations with CVD and color adaptation were performed. Furthermore, a statistical experiment was performed using volunteers with CVD in order to verify the effectiveness of the proposed visual accessibility technique in MPEG‐21. Both the experimental and simulation results show that the proposed adaptations technique can provide better color information, particularly to people with CVD.
