  • Publication number: 20140099767
    Abstract: An insulating film and another insulating film are formed over a semiconductor substrate in that order to cover first, second, and third gate electrodes. The another insulating film is etched back to form sidewall spacers over side surfaces of the insulating film. Then, the sidewall spacers over the side surfaces of the insulating films corresponding to the sidewalls of the first and second gate electrodes are removed to leave the sidewall spacers over the side surfaces of the insulating film corresponding to the sidewalls of the third gate electrode. Then, the sidewall spacers and the insulating films are etched back, so that the sidewall spacers are formed of the insulating film over the sidewalls of the first, second, and third gate electrodes.

  • Patent number: 8542953
    Abstract: An image processing apparatus supports image processing in multiple languages via a user interface, a determining unit, a setting unit, and a character recognizing unit. The user interface sets an instruction from a user for various functions performed by the image processing apparatus. The user interface displays characters in a language. The determining unit automatically determines the language currently used for the characters displayed in the user interface of the various functions. The setting unit sets, in response to the determining unit automatically determining the language currently used for the characters displayed in the user interface, the determined language as a scanned document language for use in recognizing characters in a scanned document which is obtained by scanning a paper document. The character recognizing unit utilizes the scanned document language set by the setting unit to recognize characters in the scanned document and create text data.

  • Patent number: 8319987
    Abstract: When generating one file from image data having plural pages, the present invention generates coded data of a background portion that is common to plural pages for sharing the coded data, thereby realizing a file compressed at high compression rate while maintaining image quality. For this, the apparatus reads plural pages. In the page processing, the read page image is separated into a text image and a background image. The background image is divided into predetermined pixel blocks, then comparison is performed with respect to a certain position between one page and a previous page in units of pixel block, and common pixel blocks are separated from page-unique pixel blocks. When reading of all pages is completed, a page image is generated with the text image and the page-unique background image. Thereafter, the background image common to plural pages is linked to corresponding pages for generating one file.

  • Patent number: 8224131
    Abstract: An image processing apparatus includes a user interface for setting an instruction from a user and is capable of switching a language used in a display screen of the user interface. The image processing apparatus creates text data by determining the language used in the display screen of the user interface and by performing character recognition suitable for recognizing a document of the determined language on read image data. The image processing apparatus also creates a file in which the text data and the image data are associated with each other. Therefore, character recognition is properly performed in the image processing apparatus by automatically selecting the type of the language.
