Adaptation (eye)

In ocular physiology, adaptation is the ability of the eye to adjust to various levels of light.

Biological pigment

Biological pigments, also known simply as pigments or biochromes, are substances produced by living organisms that have a color resulting from selective color absorption.

Candela

The candela (or; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction.

Candela per square metre

The candela per square metre (cd/m2) is the derived SI unit of luminance.

Color vision

Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit.

Cone cell

Cone cells, or cones, are one of three types of photoreceptor cells in the retina of mammalian eyes (e.g. the human eye).

Contrast (vision)

Contrast is the difference in luminance or colour that makes an object (or its representation in an image or display) distinguishable.

Focal Press

Focal Press is a publisher of media technology books and it is an imprint of Taylor & Francis.

Human eye

The human eye is an organ which reacts to light and pressure.

International System of Units

The International System of Units (SI, abbreviated from the French Système international (d'unités)) is the modern form of the metric system, and is the most widely used system of measurement.

Intrinsically photosensitive retinal ganglion cells

Intrinsically photosensitive retinal ganglion cells (ipRGCs), also called photosensitive retinal ganglion cells (pRGC), or melanopsin-containing retinal ganglion cells (mRGCs), are a type of neuron in the retina of the mammalian eye.

Lumen (unit)

The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source.

Luminance

Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction.

Luminous efficacy

Luminous efficacy is a measure of how well a light source produces visible light.

Mesopic vision

Mesopic vision is a combination of photopic vision and scotopic vision in low but not quite dark lighting situations.

Photometry (optics)

Photometry is the science of the measurement of light, in terms of its perceived brightness to the human eye.

New!!: Photopic vision and Photometry (optics) · See more »

Purkinje effect

The Purkinje effect (sometimes called the Purkinje shift) is the tendency for the peak luminance sensitivity of the human eye to shift toward the blue end of the color spectrum at low illumination levels as part of dark adaptation.

Retina

The retina is the innermost, light-sensitive "coat", or layer, of shell tissue of the eye of most vertebrates and some molluscs.

Scotopic vision

Scotopic vision is the vision of the eye under low-light levels.

Spatial frequency

In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space.

New!!: Photopic vision and Spatial frequency · See more »

Visible spectrum

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.

New!!: Photopic vision and Visible spectrum · See more »

Visual acuity

Visual acuity (VA) commonly refers to the clarity of vision.

New!!: Photopic vision and Visual acuity · See more »

Visual perception

Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment.
