  • Publication number: 20140185070
    Abstract: An image processing device includes a mode instruction information obtaining section, a color determination threshold storage section, a mode determination section, and an automatic color determination threshold adjustment section. The mode determination section, using a color determination threshold, determines a mode to be a color mode when the image data belongs to a color mode range, and determines the mode to be a monochrome mode when the image data belongs to a monochrome mode range. The automatic color determination threshold adjustment section adjusts the color determination threshold so as to widen a mode range corresponding to the mode determined by the mode determination section, when the mode indicated by the instruction information obtained by the mode instruction information obtaining section is different from the mode determined by the mode determination section.

  • Patent number: 8681402
    Abstract: An image processing apparatus includes a document conveying unit, an image reading unit, a gradient calculating unit, a gradient comparing unit and a document discriminating unit. The image reading unit scans a document conveyed by the document conveying unit in a scanning direction orthogonal to a conveying direction and detects pixel values of color components of each pixel. The gradient calculating unit calculates a gradient of the pixel value of each color component in the conveying direction for each pixel based on the detected pixel values. The gradient comparing unit compares differences of gradients among color components for each pixel and extracts the pixel where the graduent difference is below a threshold value. The document discriminating unit discriminates whether each pixel is color or black-and-white based on pixel values using discrimination criteria different for the specific pixels extracted by the gradient comparing unit and other pixels.

  • Patent number: 8619325
    Abstract: An image processing apparatus includes an image reading unit, a pixel color determining unit, an isolated point determining unit, and a document discriminating unit. The image reading unit scans a document to detect pixel values of color components of each pixel. The pixel color determining unit determines whether a color of each pixel is a specific color based on the detected pixel values. The isolated point determining unit determines whether each pixel is an isolated point based on the detected pixel values. The document discriminating unit discriminates whether the document is a color document or a black-and-white document based on the detected pixel values while treating the pixels, of which the color has been determined to be the specific color by the pixel color determining unit and which have been determined to be isolated points by the isolated point determining unit, as black-and-white pixels.

  • Patent number: 8514456
    Abstract: An image forming apparatus has R, G and B dot pattern detection units that detect the presence/absence of image data of operation restricting dot patterns of R, G and B color components respectively in document image data. A dot pattern color determination unit determines the presence/absence of the operation restricting dot pattern and the color of the operation restricting dot pattern on a document from the detection results from the detection units. A restriction detail table storage unit stores, beforehand, a table showing the correspondence relationship between the color of the operation restricting dot pattern and a restriction detail concerning a copy operation. An image formation control unit determines, based on a determination of the dot pattern color determination unit and the table, whether a current setting of a multi-functional peripheral is relevant to the restriction detail corresponding to the color, and, when relevant, prohibits the copy operation.

  • Publication number: 20130125877
    Abstract: The hydrolytic saccharification method and hydrolytic saccharification apparatus according to the present invention use a hydraulic cylinder-type pressurized reactor as a reactor for causing cellulosic biomass to be in a supercritical or subcritical state, and use a hydraulic cylinder-type steam compressor as a source of superheated steam, such that the reactor and the compressor are operated in conjunction with each other. Surplus hydraulic pressure that is generated when hydrolysis of the cellulosic biomass is completed is recovered as compression power of the hydraulic cylinder-type steam compressor. Moreover, flash steam generated from slurry containing a hydrolysate is supplied to the hydraulic cylinder-type steam compressor for cyclic use of the flash steam.

  • Patent number: 8427699
    Abstract: An image formation controller judges whether or not a tint block has been detected by a tint block processor upon judging that an automatic color determination mode is set in a multi functional peripheral. The image formation controller causes an image forming section to perform a monochromatic image forming operation if the tint block is a chromatic tint block when the tint block was detected by the tint block processor. On the other hand, the image formation controller causes the image forming section to perform an image forming operation corresponding to a determination result by an ACS processor when no tint block was detected and when the tint block was determined to be a monochromatic tint block.

  • Patent number: 8284456
    Abstract: A special pattern determination section determines whether a special pattern is included in a document image read by a document reading section. If the special pattern determination section determines that the special pattern is included, the breaking pattern applying section applies a breaking pattern to the document image, and the print image generating section accumulates image data of the document image applied with the breaking pattern into a memory. On the other hand, if it is determined that the special pattern is not included, the print image generating section accumulates the image data of the document image directly into the memory. Then, if it is set by a user so as not to print the breaking pattern, the controller deletes image data of the document image accumulated in the memory and applied with the breaking pattern.
