The proposed TVPIQA metric will focus on two human visual sensitivity factors, that is, image structures and luminance changes in enclosed regions.
The luminance of the disk was either 3.2, 10, or 32 cd/[m.sup.2] in 3 equal steps along a logarithmic scale.
(4), which reported age-related sensitivity losses to the frequencies of 0.25, 1.0, 2.0, and 4.0 cpd in mesopic luminance conditions.
It was confirmed that the device luminance was improved with increasing the Ti[O.sub.2] NPs content.
The OLED lighting module offers color rendering (CRI>90) suitable for lighting applications, as well as achieving high luminance, high efficiency (17 lm/W), and long lifespan (10,000 hours).
Via software controls, three slides were created of approximately equal photopic luminance (that is, 0.5 cd/[m.sup.2] when reflected on the windshield and viewed from the driver's seat) but different color (that is, white, blue, and red).
The head was surrounded by a ring of white matte paper that served as an object for the investigation of luminance. The luminance was measured by a luminance meter (Konica Minolta LS110) with the objective directed towards the ring.
The perfect replication of the microlens enables us not only to make a rigorous design of a LGP and also to achieve the LPG showing a desired luminance. In this regard, further injection-molding experiments should be required to find a proper processing window for obtaining a LGP with perfectly replicated microlenses.
According to Equation 1, lightness ([L.sup.*]) only depends on comparing (l/[l.sub.n]), the luminance (l) of a surface with the luminance corresponding to the reference white (ln).
