  • Patent number: 7733511
    Abstract: The invention provides an image processing system which can give different securities to data of respective receivers with a simple operation and, in this case, which can realize shortening of time for communication to a destination and suppression of use of memory resources. A plurality of regions preset in image data are related to destinations, code data constituting one of regions corresponding to the destinations or the other regions is replaced with code data which make pieces of information included in the regions invisible in the JPEG2000 file transmitted to the destinations, and the JPEG2000 file after the replacing process is transmitted to the destinations.

  • Patent number: 7483582
    Abstract: On JPEG2000 coding apparatus, the coding process is performed by discriminating an area defined by each object contained in image data and specifying type of the object, performing character recognition processing on the area discriminated as that containing a character to produce a text data and producing an XML data corresponding to said text data, adding an XML box that can store a specific data into a bit stream constructing said JPEG2000 file so as to be positioned in back of a predetermined level of wavelet decomposition and causing said XML box to store said XML data. On the other hand, on JPEG2000 decoding apparatus, the decoding process is performed by causing user to select whether to read an XML box added into a bit stream of JPEG2000 file in the middle of JPEG2000 decoding process, and processing the XML data stored in the XML box to acquire a text data.

  • Patent number: 7266215
    Abstract: An additional data useful for the management of copies of a document for an image forming apparatus is embedded in a hard copy of the document. The additional data is embedded in an inherent image of a document as discrete dots arranged in a prescribed format. Preferably, the size of each of said discrete dots is not so large as to be recognized easily with naked eyes. The additional data can be embedded in unit of blocks. Further, the density of the discrete dots is different from the density adjacent to the discrete dots. The image data for embedding an additional data can be obtained by reading a document, or by receiving data sent from a computer or read from a floppy disk. An additional data embedded in a hard copy can be extracted from the image data on the hard copy. Further, the production of a copy according to the image data can be controlled according to the extracted additional data.

  • Patent number: 6615291
    Abstract: A bus monitor section 8 calculates bus-occupancy rate for each of the DMA control sections 1 to 3 connected to a bus 5 in accordance with bus-use permission signals ack1 to ack3, respectively. Furthermore, a bus-use reconcilement section 6 changes manners of bus-use reconcilement control when the sum of a plurality of bus-occupancy rate exceeds “50”, a predetermined threshold. Thereby, this method avoids occurrences such that a specific device occupies the bus 5 or vice versa, a specific device cannot get access to the bus 5.

  • Patent number: 6335801
    Abstract: With facsimile apparatuses wherein color image data is coded, a facsimile on a calling side codes image data by replacing the image data with a codeword indicative of a white run-length or a black run-length, represents color information by combining specific codewords among the codewords and represents image data including color image only by codewords by combining the coded image data and the color information. A facsimile on a called side receives transmitted image data, determines color information represented by a combination of specific codewords among the codewords in the received image data, and outputs image data as specific color image when the color image is determined.

  • Patent number: 6307981
    Abstract: A memory error detecting device for an image forming apparatus having a memory unit, a first generating means, a second generating means, a comparison means, and a memory error warning means. The first generating means generates first information related to first image data input to the memory unit. The second generating means generates second information related to second image data output from the memory unit. The comparison means compares the first information with the second information, and generates a comparison result signal. The memory error warning means signifies an error in the memory unit when the comparison result signal indicates that the first information differs from the second information.

  • Patent number: 6034796
    Abstract: In data processing wherein image data are processed by dividing them into blocks, a chroma data W is obtained from the color difference data W.sub.R and W.sub.B, and the color difference data W.sub.R and W.sub.B are corrected according to an amplitude of the chroma data W. For example, if the chroma W is smaller than a prescribed threshold value, the color difference data W.sub.R and W.sub.B are set as zero. Then, the so-called block distortion can be prevented. The degree of the correction may depend on the amplitude of the chroma data W. On the other hand, DC coefficients of discrete cosine transform coefficients of adjacent blocks are compared with each other. When the DC coefficients are different from each other, block distortion occurs if they represent a same image. Then, if differences of DC coefficients of discrete cosine transform coefficients of adjacent blocks are small with each other, the DC coefficients are corrected to tend to have similar values.

  • Patent number: 5995241
    Abstract: Image data of a pixel matrix are subjected to orthogonal transformation to coefficient data, which are then quantized with a first quantization table for character image and with a second quantization table for half-tone image. Image data are discriminated as character image data or half-tone image data according to the quantization data. The quantization data corresponding to the discrimination are subjected to entropy coding. Image data can be divided into first processing blocks of m*m pixel matrices and second processing blocks of M*M pixel matrices where M>m. A second processing block includes one first processing block and adjacent pixels. Image data in first and second processing blocks are subjected to orthogonal transformation to coefficient data. Coefficient data of the second processing block indicates whether the image is a character image, a dot image, or a half-tone image, permitting selection of an appropriate quantization table.
