Note (2) Definition of Contrast Ratio, CR:
The contrast ratio can be calculated by the following expression.
Contrast Ratio, CR = L63 (255) / L0
L63: Luminance of gray level 63 (255)
L 0: Luminance of gray level 0
CR = CR (5)
CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (6).
