Patent number: 7986797Abstract: A signal processing system, a signal processing apparatus and method, a recording medium, and a program in which high frequency components of a narrow-range signal having suppressed high frequency components can be restored with high accuracy. A narrow-range audio signal having low frequency components is divided into frames by a frame-unit dividing unit, and is spectral-transformed into a signal on a frequency domain by a DCT transform unit. A learning-produced-data table extracts, at an address corresponding to a class code supplied from a classifying unit, high-frequency-component DCT spectrum data. In a spectrum combining unit, the extracted high-frequency-component DCT spectrum data is combined with low-frequency-component DCT spectrum data output from the DCT transform unit. Subsequently, a broad-range audio signal having combined high frequency components and low frequency components is output.Type: GrantFiled: October 1, 2009Date of Patent: July 26, 2011Assignee: Sony CorporationInventors: Tetsujiro Kondo, Masaaki Hattori, Tsutomu Watanabe, Hiroto Kimura, Sakon Yamamoto, Akihiko Arimitsu

Patent number: 7957471Abstract: In encoding input image data including first and second images, the first image is divided into blocks. A second block corresponding to a first block that is one of the blocks is detected from the second image. Pixels forming the first and second blocks are sorted in order according to pixel values. Block difference data indicating the amount of change in the pixel values of the sorted pixels between the first and second blocks is determined and encoded. In decoding, block information identifying the second block, sort-order information indicating the sorted pixels forming the first block, and the encoded block difference data are obtained. The encoded block difference data is decoded. The decoded block difference data and the second block identified by the block information are used to generate pixel values of the first block. The generated pixel values are reverse-sorted according to the sort-order information.Type: GrantFiled: January 25, 2006Date of Patent: June 7, 2011Assignee: Sony CorporationInventors: Tetsujiro Kondo, Sakon Yamamoto
