  • Publication number: 20100064036
    Abstract: An operation method of peripheral device includes setting up connection of peripheral device to host, directly loading firmware of said peripheral device from said host, and operating said firmware by said peripheral device. The requirement of the peripheral device to non-volatile memory capacity is decreased. By pre-storing the firmware of the peripheral device in the host, the requirement of the peripheral device to non-volatile memory capacity is decreased. And it is not necessary to download the firmware in the non-volatile memory frequently when producing and debugging the peripheral device. Only loading the firmware of the peripheral device from the host directly is needed, and the efficiency is improved.

  • Publication number: 20090303038
    Abstract: The present invention discloses a method for obtaining the direction of a target location through a handset, which includes: the handset obtains geographical information of a current location and that of the target location, determines a geographical meridian line of the current location and a angle of this geographical meridian line displayed on the screen of the handset; the handset determines the direction from the current location to the target location according to geographical information of the current location and that of the target location, determines an included angle between this direction and the geographical meridian line. According to the included angle and that of the geographical meridian line displayed on its screen, the handset determines the direction displayed on the screen of the handset from the current location to the target location, and displays the direction of the target location on the screen according to the displayed direction.

  • Publication number: 20090263025
    Abstract: A preprocessing section binarizes input image data and calculates a total black pixel ratio. A feature extracting section detects connected components contained in the binarized image data and detects circumscribing bounding boxes that circumscribe these connected components, respectively. Based on sizes of the circumscribing bounding boxes detected and numbers of black pixels contained therein, predetermined connected components are removed. A determining section generates an edge map by using the residual connected components, and performs two-dimensional fast Fourier transform thereon to generate spectral data. The determining section performs two-dimensional fast Fourier transform on template images to generate spectral data. The determining section determines, based on these pieces of spectral data, whether or not a circular shape is contained in the input image data.

  • Publication number: 20090245640
    Abstract: A preprocessing section binarizes input image data and calculates a total black pixel ratio. A feature extracting section detects connected components included in the binary image data and detects circumscribing bounding boxes of the connected components. Predetermined connected components are removed from all of the connected components based on the sizes of the detected circumscribing bounding boxes and bounding box black pixel ratios. By using the connected components that remain after removing the unnecessary connected components, a histogram is generated by specifying the sizes of the circumscribing bounding boxes as classes and numbers of the connected components as the frequencies of occurrence. A determining section determines whether the input image data is document image data or non-document image data based on information related to the generated histogram and the total black pixel ratio.

  • Publication number: 20090180690
    Abstract: When the gray processing section converts input image data into gray image data, the histogram generating section generates a histogram that represents the distribution of the number of pixels of the gray image data. Then, based on the gray level of a target pixel and the gray levels of a plurality of neighbor pixels surrounding the target pixel in the shape of an approximate circumference, rotation-invariant features indicating local texture feature centering on the target pixel are calculated for each of the pixels, and a histogram is generated based on the calculated feature. Thereafter, the search section searches for similar image data based on the histogram of the registration image data and the histogram of the input image data, and the display section displays the result of search.
