The original content is graded in dark environment with very low ambient light. When displayed at outdoor in very bright ambient light, the dark areas and black details are seriously washed out. Tone mapping curve will be designed to recover these lost details and make them obviously better than the current existing outdoor TVs. Shadow detection and bright scene detection are utilized to adaptively control the compensation process. Results show that the proposed outdoor ambient compensation can help to reveal the dark details while maintaining high contrast in mid-tone and highlight areas.
