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.

The SPECK coding algorithm is a fully embedded block-based coder which employs progressive transmission by coding bit planes in decreasing order.
Here, the bits of the image are directly embedded into least significant bit plane of the cover-frame in a deterministic sequence.
