bit plane

(graphics)
(Or "bitplane") The memory in a graphic display device which holds a complete one-bit-per-pixel image. Several bit planes may be used in conjunction to give more bits per pixel or to overlay several images or mask one with another.

"Bit plane" may be used as a synonym for "bitmap", though the latter suggests the data itself rather than the memory and also suggests a graphics file format.

bit plane

(1) The sequence of bits for each pixel in a bitmap. The number of bits in the bit plane determines the number of colors that are displayed in the image. See bitmap and color depth.

(2) A segment of memory used to control an object, such as a color, cursor or sprite. Bit planes may be reserved parts of a common memory or independent memory banks each designed for one purpose.
