Patent number: 8599918Abstract: When a periodic pattern is not included in image data 210, a prediction error encoding unit 204 outputs the variable-length code of a prediction error quantization value 214 generated by prediction encoding as compressed data 215. When the periodic pattern is included in the image data 210, a periodic pattern encoding unit 208 outputs only information about the periodic pattern as the compressed data 215, while the output of the prediction error encoding unit is stopped. On the decompression side, while the copy instruction of a pixel value before one cycle from the compressed data is not detected, the decompression operation in a normal prediction encoding system is executed. When the instruction is detected, the pixel value one cycle before, internally stored is copied and outputted.Type: GrantFiled: April 13, 2010Date of Patent: December 3, 2013Assignee: Fujitsu LimitedInventors: Shigeru Yoshida, Junichi Odagiri

Patent number: 8467619Abstract: In the present invention, a first pixel data group of several pixels existing in block into which an image is divided is divided, thereby generating several second pixel data groups. In the second pixel data group, an orthogonal transformation is performed in several layers using only the predetermined number of coefficients from the lowest frequency side from among the coefficients obtained by the orthogonal transformation. The predetermined number of coefficients from the lowest frequency side from among the coefficients obtained by the orthogonal transformation in the highest layer, and the coefficients that are obtained in a layer other than the highest layer not used for the orthogonal transformation are encoded, thereby generation the compressed data. Accordingly, encoding is performed while separating lower frequency components from higher frequency components.Type: GrantFiled: September 21, 2009Date of Patent: June 18, 2013Assignee: Fujitsu LimitedInventor: Shigeru Yoshida

Patent number: 8311107Abstract: A quantizer quantizes a “prediction error” as a difference value between a pixel X to be compressed and a prediction value X?. A variable-length encoder inputs a quantization number obtained from a quantization table of the quantizer, and outputs a variable-length code (compressed code). A prediction value candidate calculation module calculates candidates 1 through k for a prediction value on the basis of peripheral pixels A, C, and B, and transmits them to a multiplexer (MPX). A prediction value determination module determines a prediction value among the candidates 1 through k for a prediction value on the basis of an intermediate value correspondence table and an intermediate value—image format correspondence table depending on an image format, and transmits a control signal to the multiplexer (MPX). The multiplexer (MPX) outputs one of the candidates 1 through k for a prediction value as a prediction value X?.Type: GrantFiled: November 10, 2008Date of Patent: November 13, 2012Assignee: Fujitsu LimitedInventors: Junichi Odagiri, Hironori Yahagi, Shigeru Yoshida
