Patent number: 6377361Abstract: In an image processing device, image data is buffered by an image buffer section to output an interested pixel value and surrounding pixel values of a pixel surrounding an interested pixel. A shift condition determination section determines on the basis of the interested pixel value and the surrounding pixel values whether or not the interested pixel value should be shifted, and outputs a shift determination result. A pixel shifting amount computing section computes the pixel shifting amount of the interested pixel, and the shifted pixel position calculation section outputs a shift pixel position signal on the basis of setting parameters Tx and Ty, and clock signals XCLOCK and YCLOCK. A pixel value shifting section outputs the interested pixel value after the shifting on the basis of the interested pixel value, a shift determination result, the pixel shifting amount, and the shift pixel position signal.Type: GrantFiled: January 12, 1999Date of Patent: April 23, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Eiichi Sakaue, Naofumi Yamamoto, Hidekazu Sekizawa, Hiroki Kanno

Patent number: 6154569Abstract: A coding and/or decoding system for an image including bit-sops of different levels, is provided in an image recoding system which recodes bit-map data including small-level bit-map data and multilevel bit-map data in an image memory and which read the bit-map data out of the image memory to recode an image. In this coding and/or decoding system, after small-level bit-map data and multilevel bit-map data are divided into blocks, each of which is composed of a plurality of picture elements, the divided small-level bit-map data and the divided multilevel bit-map data are inputted to small-level bit-map data coding section and multilevel bit-map data coding section, respectively. The small-level bit-map data are transformed into codes representative of the number of black or white and half-tone picture elements in the block, and the multilevel bit-map data are transformed into codes representative of the average value or the total in the block.Type: GrantFiled: March 15, 1996Date of Patent: November 28, 2000Assignee: Kabushiki Kaisha ToshibaInventors: Eiichi Sakaue, Sunao Tabata, Naofumi Yamamoto, Hidekazu Sekizawa

Patent number: 6124867Abstract: A picture output apparatus capable of carrying out picture output at a high speed is provided. In the picture output apparatus adapted for converting picture data of a first form, which is not permitted to undergo picture output, inputted along with a picture output instruction into picture data of a second form which is permitted to undergo picture output, wherein this apparatus comprises a configuration to convert picture data of the first form inputted without the picture output instruction into picture data of the second form to hold it as predictive picture data of the second form with respect to picture data of the first form predicted to be inputted along with the picture output instruction later. In the case where the picture data of the first form inputted along with the picture output instruction and the previously inputted picture data of the first form are the same, since the picture data of the second form already exists, it is possible to carry out picture output without conversion processing.Type: GrantFiled: July 17, 1996Date of Patent: September 26, 2000Assignee: Kabushiki Kaisha ToshibaInventor: Eiichi Sakaue
