Rod 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 کاملA 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 کاملA Retargeting Approach for Mesopic Vision: Simulation and Compensation
Retargeting approaches aim at providing a unified framework for image rendering in which both the intended scene luminance and the actual luminance of the display are taken into account. At the core of any color retargeting method, a color vision model and its inverse are employed. Such a color appearance model should be invertible and cover the entire luminance range of the human visual system...
متن کاملColour vision and visual performance in the mesopic range of vision
The aim of this work is to predict mesopic detection contrast thresholds for spectral increments on a fixed uniform mesopic background. A compound contrast-type quantity C including achromatic and chromatic terms is defined. The detection threshold is characterized by C=1. From this criterion, a spectral non-additivity formula (NA) is derived for a mesopic luminance difference type quantity. Ac...
