Parameters
The YE0223 is designed for evaluation of the halftone reproduction of electronic cameras.
Two 13-graduated counter current gray scales are arranged on a gray background. The gray scales being graduated logarithmically.Related to the densities of the gray scales: gamma = 0.45, related to the transmission values (brightness): gamma = 2.2, that being exactly the reciprocal value of gamma = 0.45.
The output signal of a optimally gamma-corrected camera yields two 13-graduated counter current linear step signals.
The contrast range of the gray scales is 200 : 1.
