Patent number: 9443178Abstract: An image processing apparatus includes a detection unit and a determination unit. The detection unit detects an error by comparing image data related to a print job with read image data obtained as a result of reading a print output related to the print job. The determination unit compares read image data related to a post-error print output, which is a continuously-printed print output related to the print job for a page subsequent to a page in which the error is detected, with the image data when the error is detected by the detection unit, so as to determine a process for recovering the print job by using the post-error print output.Type: GrantFiled: March 9, 2015Date of Patent: September 13, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Katsuyuki Asai, Toshiaki Yoshinari, Bo Liu, Takuya Mizuguchi, Toshio Kamada, Kentaro Ikeda, Kazuki Nagashima

Patent number: 6118552Abstract: An image signal encoding apparatus reads an image from an original and converts the image into color data values including lightness and chromaticity components. The data values are stored and divided into pixel blocks with data values of lightness components and pixel blocks with data values of chromaticity components. Average lightness component data values are computed for pixel blocks of lightness components and average chromaticity data values are computed for pixel blocks of chromaticity components. A region determination is made whether the pixel blocks correspond to color, monochrome or background region in the original based on the average pixel block data values of lightness components and chromaticity components. A switch outputs the lightness pixel block data values during the region determination, and outputs the lightness and chromaticity pixel block data values after the region determination.Type: GrantFiled: August 6, 1996Date of Patent: September 12, 2000Assignee: Fuji Xerox Co., Ltd.Inventors: Kazuhiro Suzuki, Toshiaki Yoshinari, Taro Yokose, Ken Umezawa

Patent number: 5570203Abstract: An image signal coding device capable of attaining a high-speed coding operation without increasing a circuit scale. The image signal coding device includes a DCT section for performing two-dimensional orthogonal transform to each of plural pixel blocks obtained by dividing an image signal to generate a transform coefficient, a linear quantization section for linearly quantizing the transform coefficient by using given quantization characteristics to generate a quantized coefficient, and a variable length coding section for performing variable length coding to the quantized coefficient to generate code data. The image signal coding device further includes an effective region holding section for holding region information including a range of the transform coefficient to be linearly quantized by the linear quantization section and a range of the quantized coefficient to be coded by the variable length coding section.Type: GrantFiled: October 20, 1994Date of Patent: October 29, 1996Assignee: Fuji Xerox Co., Ltd.Inventors: Kazuhiro Suzuki, Taro Yokose, Toshiaki Yoshinari, Yutaka Koshi, Koh Kamizawa

Patent number: 5416693Abstract: A moving picture search support device allows a particular scene or frame to be searched quickly and surely from a moving file that has been accessed in the past based on weighing that is derived from an evaluation made by the degree of importance. The device of the invention, which is used to reproduce a moving picture, includes an operation history storage unit and a history calculating unit. The operation history storage unit stores history data that has been given a predetermined weight corresponding to an operation mode selected for processing a moving picture file by a user. The history calculating unit determines, in response to a search request made by the user for desired moving picture data within the moving picture file, a priority level at which the desired moving picture data is displayed in accordance with the predetermined weight based on the history data stored in the operation history storage unit.Type: GrantFiled: August 26, 1992Date of Patent: May 16, 1995Assignee: Fuji Xerox Co., Ltd.Inventor: Toshiaki Yoshinari
