Color images are often viewed on CRT monitors with the widespread PCs and Internet. We clarified the term “gamma 1 )” which represents the monitor's tone characteristics, since this term is ambiguously used. Also, an accurate characterization method of CRT monitors was considered because it is essential to have color matching with other color imaging devices. We compared several characterization methods at different settings of the user‐controlled contrast and brightness, and found a more accurate characterization method than the conventional methods.
