Abstract: An adaptive filter is disclosed, having a plurality of computation groups, a plurality of computation circuits, a summation circuit, a slicer circuit, an updating circuit, and a control circuit. Each computation group corresponds to an equalization parameter and has a plurality of memory cells. When the corresponding equalization parameter of a computation group is greater than a predetermined value, the control circuit configures the computation group and the computation circuit to collaboratively generate an output of the computation group. The summation circuit sums up the outputs of the computation groups to produce a filter output. The slicer circuit generates a slicer output according to the filter output. The updating circuit updates the equalization parameters according to the filter output and the slicer output.

Abstract: A method for transmitting a three-dimensional (3D) image is provided. The 3D image is transmitted via an image transmission interface according to a 2D image data format. The method includes steps of: receiving a 2D image data and an image depth data; down-sampling the 2D image data to generate an image sampling data; and transmitting the 3D image comprising the image sampling data and at least one part of the image depth data via the image transmission interface.
