Testing for Colour Blindness:
Cones are the photoreceptors responsible for detecting colour when your eye is forming and processing an image. Some people have cones that are unable to detect certain colours. When this happens, the person is considered to have some degree of colour blindness!

Image Formation: Technology
|
The eye is very effective at forming images; however, unless one has an eidetic memory, the ability to remember what we have seen is not as effective. Thankfully, there are many ways in which we can store images.
Digital images use the same principle as stadium images. Stadium images are created when large groups of people hold a coloured card, depicting an image. Creating stadium pictures takes a lot of organization. |
When a computer receives an image, it divides the picture into small elements called pixels (short for picture element). The pixels act like the individual colour cards of a stadium image. The computer is able to remember the placement of each piece in order to recreate the image.
