1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
As high quality properties of digital TV like HDTV, 4K UHDTV and 8K UHDTV have been demanded, it is necessary to present the highest image quality with rich and authentic color, subtle gray and color tone and dynamic contrast, and set the suitable and advanced evaluation methods of display quality. The aim of various methods for measuring color gamut, brightness, and contrast based on human perception have been studied is to match the image quality with human eyes. Even though there are conventional measuring methods like luminance, tristimulus values for the objective evaluation method, there are imperfect methods considering a viewing condition, perceptual parameters. The basic rationale of this proposal is the color appearance model which is proposed at CIE in 2002. A new method is to calculate a color volume and contrast with color appearance model which is uniform color space with human visual perception.



b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information:

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.
