摘要： The present invention relates to an image processing device and method that enable generation of a highly precise prediction image without increasing a processing load.An image formed in units of macroblocks of 16×16 pixels attached with a band area having a width of “a” pixels serving as a margin area is extracted as a motion compensation image from a reference frame and is regarded as an input image of a filtering process. “a” is a value that is determined in accordance with the number of taps of an FIR filter. A filtering process is performed using such a motion compensation image as an input image, and a prediction image of 16×16 pixels is output as an output image of the filtering process. The prediction image is added to an output image of an inverse orthogonal transformation circuit in an adder circuit, and an image as a result of the addition is used as a macroblock constituting a decoded frame. The present invention can be applied to a device that performs prediction encoding and a device that decodes information encoded through the prediction encoding.

摘要： An apparatus and method provide logic for processing an image. In one implementation, a computer-implemented method is provided to process an image. The method receives information associated with pixels of the image disposed in pixel blocks, and selects one of the pixel blocks as a target block. A motion vector associated with a translation of pixels of a portion of the target block from reference positions in a previously-encoded image is computed at less than integer precision. The method computes predicted image data for the pixels of the target block based on at least the received information and the motion vector, and filters the predicted image data according to a predetermined process. The predetermined process is applied to predicted image data associated with pixels adjacent to a boundary pixel of the target block.
