Patent number: 7002709Abstract: The reproduction of a copy inhibit image and the abuse of data through a network are to be prevented without sacrificing various page editing functions. An image read unit scans an original placed on an original carrying table and thereby generates RGB color image signals of multi-value. An image processing unit performs various image processing and, upon detection of a copy inhibit original, performs image working for preventing faithful reproduction of the copy inhibit original. An image storing unit temporarily stores page by page original images provided from the image processing unit. If a copy inhibit image is contained in the original images, the image working is performed by the image processing unit to prevent faithful reproduction and the images after the image working are stored in the image storing unit. An image output unit performs a printing operation in accordance with image data outputted from the image processing unit.Type: GrantFiled: November 10, 1999Date of Patent: February 21, 2006Assignee: Fuji Xerox Co., Ltd.Inventors: Yoshihiro Terada, Kenji Ebitani, Kazuman Taniuchi, Hiroyoshi Uejo, Junichi Shimizu

Patent number: 6621944Abstract: A color copying apparatus is capable of making copies without performing a prescan. Input image data of RGB format read from an image input unit is written in an image memory through the shading/gap correction unit and an input &ggr; correction unit. This input image data is supplied to a detection unit through a first color space conversion unit to distinguish color from monochrome in the input image data, and to detect the base color level and the like. Next, on the basis of these detection results, states of a second color space conversion unit, a selector, a frame-erase/base color removal unit and the like are set. Thus, the input image data is read out again from the image memory, and is supplied to an image output unit through the first color space conversion unit to an output &ggr; correction unit.Type: GrantFiled: November 30, 1999Date of Patent: September 16, 2003Assignee: Fuji Xerox Co., Ltd.Inventors: Hisahiro Takahagi, Kazuman Taniuchi

Patent number: 5537222Abstract: A image edit apparatus in which area data of 16-bit width have been stored at the memory locations of the corresponding addresses of the respective memory planes of a plane memory 403. The operation of reading area data therefrom by a pseudo sync signal starts before a line sync signal becomes active. A density-conversion/area generating circuit 405 converts the data format from the plane type to the pixel type, so that area commands are generated. Then, the circuit 405 reads an edit command out of a logic RAM, using the area command as address, and outputs the command. By reading the area data earlier and processing that data, a delay in the density-conversion/area generating circuit can be absorbed, so that the output edit command is synchronized with the image data.Type: GrantFiled: May 8, 1992Date of Patent: July 16, 1996Assignee: Fuji Xerox Co., Ltd.Inventors: Yasuhiko Iwamoto, Kazuman Taniuchi, Hiroshi Sekine, Yoshio Ichiyanagi, Sadao Furuoya
