A Color Appearance Model Applicable in Mesopic Vision
We propose a color vision model that can be used to predict color appearance in mesopic vision as well as photopic and scotopic vision. It is based on a two-stage model which consists of the cone and opponent stages and it assumes rod intrusion at the opponent stage. The model has the following features to describe the color appearance in mesopic vision. First, it includes a gradual and nonline...
متن کاملEffects of hypoxia on color vision with emphasis on the mesopic range
10.1586/EOP.11.32 Oxygen is fundamental to animal life. It is a prerequisite for the production of biological energy through cytoplasmic glycolysis and mitochondrial oxidative phosphorylation, typically as adenosine triphosphate (ATP), to fuel metabolic reactions. ATP is generated on demand, requiring a continuous supply of oxygen, so hypoxia may be simply defined as a state of oxygenation that...
متن کاملRod and Cone Contributions to Mesopic Vision
Mesopic light levels span approximately 3-4 log units in the natural viewing environment, including many indoor lighting settings, and most twilight or nighttime outdoor and traffic lighting environments. Traditional studies of the contribution of the different photoreceptor types to mesopic vision have been hampered by an inability to modulate the rod or cone systems independently. Our approac...
متن کاملVision under mesopic and scotopic illumination
Evidence has accumulated that rod activation under mesopic and scotopic light levels alters visual perception and performance. Here we review the most recent developments in the measurement of rod and cone contributions to mesopic color perception and temporal processing, with a focus on data measured using a four-primary photostimulator method that independently controls rod and cone excitatio...
متن کاملNew color vision tests to evaluate faulty color recognition.
PURPOSE To develop and assess new color vision tests to be used in evaluating faulty color recognition. METHODS We developed new color vision tests to evaluate faulty color recognition. The two types of color vision tests, designed to assess faulty color recognition in color vision deficiencies, are based on principles that are different from those of the conventional color vision tests. In t...
