TE223 A 11-graduated Greyscale Charts reflectance test chart

 

 

Two 13-graduated counter current gray scales are arranged on a gray background (D = 0.75), 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-gratuated counter current linear step signals.

 

The contrast range of the gray scales is 200 : 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 %).

 

Remark: We support Any customized test charts only if you have high resolution image and size.

 

Other Test Charts 
Application

 

This Grey Scale chart is used in conjunction with a waveform monitor to adjust the light response characteristics (video levels of Gamma) of the camera and to ensure that these characteristics are matched in all three color channels. It is also used to adjust shading and flare. The 11-Step Grey Scale Chart is an extended range test chart intended for use with high-performance video cameras including both CCD and tube types.
