— Various gamma‐evaluation methods are investigated and newly suggested in order to establish a standard gamma metrology. First, test patterns are suggested and compared for display technologies that dynamically adjust gray levels such as global‐dimming LCDs and PDPs. Second, two gamma‐determination methods are compared and their accuracy determination methods are suggested. Third, two new models for gamma‐distortion phenomena are suggested. Finally, the monotonic characteristics of EOTF are investigated. For the most part of this study, a new international standard named ICDM‐DMS is suggested.
