Abstract:
In order to improve both image quality and encoding efficiency when an image is compressed/encoded, transmitted, and recorded, an image compression apparatus includes a motion search units that perform motion detection between a first frame as an input image and a reference image already created in compression/encoding, a temporal filter that performs temporal filtering for the first frame using a second frame different from the input image on the basis of a result of the motion detection, and a compression/encoding units that compress/encode an image subjected to the temporal filtering. The temporal filter determines a location of the reference image and a filter characteristic on the basis of an encoding parameter used by the compression/encoding unit.

Claim (Index 15):
An image processing method for compressing/encoding an image and decoding the compressed/encoded image,\n the compression/encoding including\n a motion search process in which motion detection is performed for each small area in an image between a first frame as an input image and a reference image already created in compression/encoding, \n a filtering process in which temporal filtering is performed for the first frame using a second frame different from the input image on the basis of a result of the motion detection, and \n a compression/encoding process in which computation of a difference from a predicted image, frequency transformation, quantization, and variable-length encoding is performed for an image subjected to the temporal filtering, \n the decoding including\n a decompression/decoding process in which the compressed/encoded stream subjected to the temporal filtering is decompressed/decoded, and \n a filter restoration process in which inverse transformation of the temporal filtering is performed for the decompressed/decoded image, \n wherein, in the filtering process, a location of the reference image and a filter characteristic are determined on the basis of an encoding parameter selected in the compression/encoding process, and in the filtering restoration process, a location of the reference image and a filter characteristic for inverse transformation of the temporal filtering are determined on the basis of the encoding parameter obtained in the decompression/decoding process, and an image previous to the temporal filtering is restored.
