The amount of distinct hues a pixel can stand for depends on the colour depth expressed in the quantity of bits per pixel. A standard way to lower the quantity of knowledge necessary in digital video is by chroma subsampling (e.g., four:4:four, 4:2:two, and so forth.). Because the human eye is less delicate to information in color than brightness, the luminance data for all pixels is preserved, although the chrominance information is averaged for many pixels in a very block, and precisely the same value is employed for all of them.
Two channels: a ideal channel for the correct eye in addition to a left channel to the still left eye. Both of those channels might be seen concurrently through the use of light-weight-polarizing filters ninety levels off-axis from one another on two video projectors.
