Evaluation method of electro-optical transfer function for display devices

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, themonotonic characteristics of EOTF are investigated. For the most part of this study, a new international standard named ICDM-DMS is suggested.
