Sample (graphics)

In computer graphics, a sample is an intersection of a channel and a pixel.

[1] The diagram below depicts a 24-bit pixel, consisting of 3 samples for Red, Green, and Blue.

In this particular diagram, the Red sample occupies 9 bits, the Green sample occupies 7 bits and the Blue sample occupies 8 bits, totaling 24 bits per pixel.

A sample is related to a subpixel on a physical display.
