IMAGING GLOSSARY

Bit plane (imaging)

A hypothetical 2-D plane containing a single bit of memory for each pixel in a image.

If each 8-bit pixel is thought of as a stack of 8 coins, and an image as many rows and columns of these stacked coins then the 3rd bit plane would be the plane consisting of the 3rd coin from each stack.

For any raster image, at least one bit plane is in frame buffer memory; each bit plane has a one-to-one mapping of bits to pixels.
