Abstract: ScalableColor Descriptor is one of the independent four Color Descriptors among MPEG-7.In this paper, we will introduce particularly the background, Descriptor components semantics, bitplane, Haar transform and matching algorithm in the MPEG-7. This article also accounts for applying scope of the descriptor and this will be helpful to those readers who will use the Descriptor.

Key words: ScalableColor Descriptor, Haar transform, bitplane
