a. Test image : 100% full white pattern with a test pattern as below

b. Test pattern : Squares, 40mm by 40mm in size, filled with 255, 225, 195, 165, 135 and

105 grays steps should be arranged at the center

of the screen.

PRODUCT INFORMATION

c. Test method

-1

gray step : move a square of 255 gray level should be moved into the center of the

screen and measure luminance and u’ and v’ coordinates.

- Next gray step : Move a 225 gray square into the center and measure both luminance and coordinates, too.

d. Test evaluation

Δu' v'= (u' - u' ) + (v' - v' )

Where A, B : 2 gray levels found to have the largest color differences between them

i.e. get the largest

u’ and ȟv’ of each 6 pair of u’ and v’ and calculate the ȟu’v’.
