In an image processing system, an apparatus for adaptively selecting three-dimensional sub-band image signal includes a circuit for obtaining energy of each sub-band of the three-dimensional sub-band signals, a circuit for extracting sub-band information on the basis of activity of higher frequency ones of the sub-band signals, a device for selecting the sub-band signals to be transferred based on a control signal generated from a look-up table in response to the extracted information, and circuitry for restoring the image signal using the selected sub-band signals and the sub-band information. A method for adaptively selecting three-dimensional sub-band signals is also disclosed.
