Patent number: 6552822Abstract: A multiple-level error diffusion processing is performed to obtain an image of a high quality with uniform texture and reduced roughness, while reducing a gradation level. An image processing apparatus comprises a first error diffusion processing section for selectively performing error diffusion processing on input image data according to its gradation values and a second error diffusion processing section for performing error diffusion processing of three or more quantization levels on the output data of the first error diffusion processing section for outputting as output image data. A selective quantization section of the first error diffusion processing section performs such a quantization that errors are supplemented selectively centering a portion where no error is produced through quantization in a quantization section of the second error diffusion processing section.Type: GrantFiled: February 23, 1999Date of Patent: April 22, 2003Assignee: Sony CorporationInventor: Masaki Kishimoto

Patent number: 6510252Abstract: An image processing method and an image processing apparatus are provided to maintain image quality through simple processing while reducing the number of gradation levels of image data by error diffusion process. In an image processing apparatus, data outputted from a filter is subtracted from input image data x(i, j) at the subtracter. Data outputted from the subtracter is quantized at a quantizer. Data outputted from the quantizer is outputted as output image data y(i, j). Furthermore, the data outputted from the subtracter is subtracted from the data outputted from the quantizer at a second subtracter to produce quantization error e(i, j). At a filter section, filtering process is performed on the quantization error e(i, j). Data outputted from the filter section is inputted to the first subtracter.Type: GrantFiled: February 23, 1999Date of Patent: January 21, 2003Assignee: Sony CorporationInventor: Masaki Kishimoto

Patent number: 6494554Abstract: An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer for suppressing satellite droplets. Two piezoelectric elements are provided for every ink chamber corresponding to each nozzle. Timing of displacement of the piezoelectric elements is adjusted by applying a drive signal for ink droplet ejection to one of the piezoelectric elements and a drive signal for suppressing satellite droplets when a droplet is ejected to the other piezoelectric element. An auxiliary pressure generated by the displacement of the latter piezoelectric element is superimposed on an ejection pressure generated by the displacement of the former piezoelectric element. Trailing of an ink droplet is cut off at an early stage and generation of satellite droplets is suppressed.Type: GrantFiled: November 25, 1998Date of Patent: December 17, 2002Assignee: Sony CorporationInventors: Shinichi Horii, Yuichiro Ikemoto, Yasuo Yukita, Hiroshi Tokunaga, Masaki Kishimoto, Yuji Yakura, Tooru Tanikawa, Shota Nishi, Kenji Suzuki

Patent number: 6445464Abstract: An image processing method and an image processing apparatus are provided for maintaining image quality through simple processing while reducing the number of gradation levels of image data by error diffusion processing. In an image processing apparatus, data outputted from a filter is subtracted from input image data x(i, j) at a first subtracter. Data outputted from the subtracter is quantified at a quantifier. Data outputted from the quantizer is outputted as output image data y(i, j). Furthermore, the data outputted from the subtracter is subtracted from the data outputted from the quantizer at a second subtracter to produce quantization error e0(i, j). At a quantization error converter, quantization error e0(i, j) is converted into quantization error e1(i, j) within a specific range determined for each quantization level, based on the quantization level after quantization at the quantizer. Quantization error e1(i, j) is inputted to the filter.Type: GrantFiled: January 21, 1999Date of Patent: September 3, 2002Assignee: Sony CorporationInventor: Masaki Kishimoto

Patent number: 6283568Abstract: An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer are provided for faithfully performing various image representations through ink droplet ejection driving signals of different waveforms. Based on a waveform selection signal from a selection controller, a waveform selector selects one of a plurality of drive signals from a drive waveform generator in a time-division manner. The selected signal is supplied to a piezoelectric element of a corresponding nozzle. Control is thereby performed on ink droplet ejection with a drive signal having a temporally varying waveform. The drive signals include a signal having a varying voltage waveform that disables ink droplet ejection in isolation from another waveform. A new composite drive signal waveform is generated by time-divisional selection not only at a point between ejection cycles but also at a point during the ejection cycle.Type: GrantFiled: August 24, 1998Date of Patent: September 4, 2001Assignee: Sony CorporationInventors: Shinichi Horii, Tooru Tanikawa, Yuichiro Ikemoto, Masaki Kishimoto, Yasuo Yukita, Hiroshi Tokunaga
