CIE scotopic luminous efficiency function V’(λ)

Target entity: CIE scotopic luminous efficiency function V’(λ)
Context triple: [International Commission on Illumination, definesStandard, CIE scotopic luminous efficiency function V’(λ)]

• A. CIE standard illuminant D65
  CIE standard illuminant D65 is a standardized representation of average daylight with a correlated color temperature of about 6500 K, widely used as a reference white point in colorimetry and imaging systems.
• B. Photometria
  Photometria is an influential 1760 treatise by Johann Heinrich Lambert that laid the foundations of photometry by quantitatively describing the measurement and behavior of light.
• C. CIE standard illuminant D50
  CIE standard illuminant D50 is a standardized light source representing average midday daylight with a correlated color temperature of about 5000 K, commonly used as a reference for color-critical applications such as printing and graphic arts.
• D. CIE standard illuminant D75
  CIE standard illuminant D75 is a defined daylight illuminant with a correlated color temperature of about 7500 K, representing cool, overcast daylight conditions for colorimetry and imaging applications.
• E. Handbuch der physiologischen Optik
  Handbuch der physiologischen Optik is a foundational 19th-century treatise on physiological optics that systematically integrated experimental physics and physiology to explain human vision.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: CIE scotopic luminous efficiency function V’(λ)
Target entity description: The CIE scotopic luminous efficiency function V’(λ) is a standardized curve that describes the human eye’s relative sensitivity to light under low-light (rod-dominated) viewing conditions across different wavelengths.
