Patent number: 9860427Abstract: An example embodiment may involve obtaining an m×n pixel cell from an input image. Each of the m×n pixels in the m×n pixel cell may be associated with at least one color value. An m×n attribute cell may be determined, elements of which may be associated in a one-to-one fashion with respective pixels in the m×n pixel cell. The m×n pixel cell may be compressed in a lossy fashion, and the m×n attribute cell may be compressed in a lossless fashion. Compression of the m×n pixel cell may be based on at least part of the m×n attribute cell. An interleaved representation of the compressed m×n pixel cell and the compressed m×n attribute cell may be written to an output medium.Type: GrantFiled: May 10, 2016Date of Patent: January 2, 2018Assignee: KYOCERA Document Solutions Inc.Inventors: Michael M. Chang, Kenneth A. Schmidt, Dongpei Su, Sheng Li, Kendrick Wong, Larry Lubman, Alfred Abkarian, Stephen L. Schafer

Patent number: 9838570Abstract: An example embodiment may involve obtaining (i) an a×b attribute macro-cell, and (ii) a×b pixel macro-cells for each of a luminance plane, a first color plane, and a second color plane of an input image. The a×b pixel macro-cells may each contain 4 non-overlapping m×n pixel cells. The example embodiment may also involve determining 4 attribute-plane output values that represent the 4 non-overlapping m×n attribute cells, 1 to 4 luminance-plane output values that represent the a×b pixel macro-cell of the luminance plane, a first color-plane output value to represent the a×b pixel macro-cell of the first color plane, and a second color-plane output value to represent the a×b pixel macro-cell of the second color plane. The example embodiment may further involve writing an interleaved representation of the output values to a computer-readable output medium.Type: GrantFiled: May 10, 2016Date of Patent: December 5, 2017Assignee: KYOCERA Document Solutions Inc.Inventors: Michael M.

Patent number: 8848250Abstract: Based on an m×n halftone matrix and an m×n pixel block of an image, an m×n halftone version of the m×n pixel block may be determined. An n-way interleave may be performed on rows of the m×n halftone version to create an mn×1 halftone segment. The mn×1 halftone segment may be compared to one or more halftone segments in a buffer. Based on the comparison, a literal code word and a representation of the mn×1 halftone segment may be output, and the representation of the mn×1 halftone segment may be written to the buffer. Alternatively, a repeat code word and a repeat value may be output, and at least one representation of the mn×1 halftone segment may be written to the buffer.Type: GrantFiled: October 23, 2012Date of Patent: September 30, 2014Assignee: KYOCERA Document Solutions Inc.Inventors: Dongpei Su, Kendrick Wong, Larry Lubman, Michael M.
