How to learn everything about computers Each of these will show up in a seprate window.
It does so by separating the luminance and chrominance components of a scene, and use less bits for chrominance than luminance.
The details of how to use less bits to represent chrominance is covered in Sub-sampling section below. How does the Conversion Work?
The conversion below is based on the conversion used in JPEG image compression.
The conversion can be expressed as equations below. This is done through color subsampling, which simply encodes chrominance components with lower resolution. Here we cover four commonly used subsampling schemes: These four schemes are illustrated by the figure below , Figure 4.
Color Subsampling The 4: Note that the sub-sampling process is lossy when comparing the processed image with the original image.
In this way, the computing system could represent the image with less bits. But how the image is reconstructed for display? Normally the image requires a Y, Cb, Cr component at every pixel. The details are not covered in this post. Applications YCbCr is a commonly used color space in digital video domain.NT - ITT Tech Flint - Course Hero - NT - Intro To Networking - ITT Tech Flint Study Resources.

Colors don’t really exist, like dust does. We human being use colors to describe what we see. The most common way to describe what we see in terms of color is using combination of red, green and blue, which is referred as RGB color space.
