  • Patent number: 9048866
    Abstract: The present disclosure provides an apparatus and a method for checking decoded data, an apparatus and a method for decoding, and a receiving terminal. The apparatus for checking decoded data includes: an arithmetic unit to perform a check computation on decoded bits output from decoders in every clock cycle to obtain a computation result, where the check computation is performed by: denoting each decoded bit as a polynomial, computing the sum of the polynomials and performing polynomial modular arithmetic on the sum; and an output unit configured to output a check result, where the check result is the sum of the computation results in all the clock cycles during a decoding process. A real-time check computation of decoded data may be realized, so that power consumption may be saved.

  • Patent number: 8660354
    Abstract: An image processing apparatus includes: a memory; an obtaining unit that obtains image data representing an image including concatenated pixels; an isolating unit that isolates a rendering element, the rendering element being an image surrounded by border lines of a color in an image represented by the image data; and a classifying unit that, in a case where a plurality of rendering elements has been isolated by the isolating unit, and in a case where color difference between two of the plural rendering elements or the distance between the two rendering elements is less than a threshold, classifies the two rendering elements into the same group, associates pieces of image data that represent rendering elements belonging to the same group with one another, and stores the pieces of image data in the memory.

  • Patent number: 8494266
    Abstract: An image processing apparatus includes a separating unit, a setting unit, and a determining unit. The separating unit separates an image into types of partial images other than a specific type, which is likely to be erroneously separated. The setting unit makes setting designating whether or not predetermined two types of partial images of the separated partial images are to be easily determined to be partial images of the specific type. The determining unit determines whether or not at least one of the predetermined two types of the partial images is the partial image of the specific type or not based upon the setting.

  • Publication number: 20110043852
    Abstract: A document output device includes an acquisition unit and a controller. When a printed document is read by a reading device and output of the document on the basis of read document information is instructed, the acquisition unit acquires at least one of attribute information of a document receiver, attribute information of an output instructor, and second identification information inputted by the output instructor. If it is determined, on the basis of a first identification information and the acquired information, that an output of a constituent element specified as an object of output restriction is not permitted, the controller restricts the output of the constituent element which is the object of output restriction in the document.
