Sine Image YE083 ITE Grayscale Chart I for Camera Mobile Phone Lens Halftone Reproduction Testing (D = 0.62)

The YE083 is designed for the evaluation of the halftone reproduction of an electronic camera. Two 11-graduated counter current gray scales are arranged on a gray background(D=0.62) . The gray scales being graduated logarithmically (gamma = 0.45).The output signal of an optimal gamma-corrected camera yields two 11-graduated counter current linear step signals. The contrast range of the gray scale is 40:1.

The values of the 11-graduated gray scale are as follows:

The density of the white field between the gray scale is D=0.05 (reflectance = 89%).
