CE ÎNSEAMNĂ DICHROMAT ÎN ENGLEZĂ?
Dichromacy
Dichromația este starea de a avea două tipuri de receptori de culoare funcționali, numiți celule conice, în ochi. Organismele cu dicromie se numesc dicromate. Dichromații pot potrivi orice culoare pe care o văd cu un amestec de maximum două lumini spectrale pure. Prin comparație, trichromații necesită trei lumini spectrale pure pentru a se potrivi cu toate culorile pe care le pot percepe. Dichromația la om este un defect de viziune de culoare în care unul dintre cele trei mecanisme de bază de culoare lipsește sau nu funcționează. Este ereditară și legată de sex, afectând predominant bărbații. Dicromația apare atunci când unul dintre pigmenții conului lipsește și culoarea este redusă la două dimensiuni.
Definiția dichromat în dicționarul Engleză
Definiția dicromatului din dicționar este o persoană a cărei viziune le face posibilă distincția între două culori. Un dicromat suferă de dicromatism.

In effect. suppose that a dichromat has two cone classes in common with a
normal trichromat and is missing the third. Consider a pair of lights that are
metameric for the dichromat but not for the normal trichromat. According to the

The Physiology of The Eye
The dichromat can match all hues (spectral and non-spectral and including white
) by appropriate mixtures of two primaries; since white can be formed by a certain
mixture of these primaries it follows that there will be a certain point in the ...

Readings on Color: The science of color
We report here experiments in which the colour perceptions from his two eyes
were compared, either directly (by dichoptic matching) or through a common
standard (by colour naming). A dichromat fails to distinguish stimuli that, to a

Finally, these ideas are applied to signal and system theory for color images. This is done using a vector signal approach where a general linear system is represented by a three-by-three system matrix.

Sensation and Perception
For all we know, he may be having an experience similar to what a person
without deficient color vision would call “yellow.” To determine what a dichromat
perceives, we need to locate a unilateral dichromatia person with trichromatic
vision in ...

The dichromat sees only a uniform faded blue.Can it be said that the visual
