|
Hue
|
a color.
|
|
|
Pupil
|
the opening in the center of the iris that helps regulate the amount of light passing into the rear chamber of the eye
|
|
|
Blind spot
|
The small, circular, optically insensitive region in the retina where fibers of the optic nerve emerge from the eyeball. It has no rods or cones.
|
|
|
top-down processing
|
a progression from the whole to individual elements
|
|
|
cones
|
specialized receptors that play a key role in daylight vision and color vision
|
|
|
opponent-process theory of color vision
|
proposes that color is perceived in three channels, where an either-or response is made to pairs of antagonistic colors
|
|
|
lens
|
the transparent eye structure that focuses the light rays falling on the retina
|
|
|
retina
|
the neural tissue lining the inside back surface of the eye that absorbs light, processes images and sends visual information to the brain
|
|
|
feature detection(detectors)
|
neurons that respond selectively to very specific features of more complex stimuli
|
|
|
intensity
|
the amount of energy transmitted; or exceptionally great concentration, power, or force
|
|
|
iris
|
the circular, colored curtain of the eye. Its opening forms the pupil. The iris helps regulate the amount of light that enters the eye.
|
|
|
rods
|
specialized receptors that play a key role in night vision and peripheral vision
|
|
|
bottom-up processing
|
a progression from individual elements to the whole
|
|
|
trichromic color theory
|
proposes that the human eye has three types of receptors with differing sensitivities to different wavelengths
|
|
|
color constancy
|
the tendency for a color to look the same under widely different viewing conditions
|
|
|
accommodation
|
making or becoming suitable; adjusting to circumstances
|
|
|
optic nerve
|
The nerve in your eye that serves to transmit information from the receptors in your eye to your brain
|
|
|
Parallel Processing
|
involves simultaneously extracting different kinds of information from the same input
|
