  • Publication number: 20110033131
    Abstract: One embodiment is a method for suppressing background inaccuracies in binary to grayscale image conversion. A binary image is converted to a grayscale image using a neighbor map. An image enhancement function is applied to the grayscale image to suppress background inaccuracies in the grayscale image. Another embodiment is method for converting a binary pixel of a binary image to a grayscale pixel of a grayscale image and suppressing noise in the grayscale image using selective filtering of the binary image. Another embodiment is a method for converting a binary image to a first grayscale image and suppressing noise in the first grayscale image to produce a noise suppressed grayscale image using selective filtering of the first grayscale image.

  • Publication number: 20110019489
    Abstract: An apparatus for data strobe and timing variation detection of an SDRAM interface includes a differential-signal to single-end signal converter, a first phase delay circuit, a data latch circuit. The differential-signal to single-end signal converter receives a differential data strobe signal from the SDRAM interface and converts the signal into a single-end data strobe signal. The first phase delay circuit is connected to the differential-signal to single-end signal converter to delay the phase of the single-end data strobe signal for producing a delayed data strobe signal. The data latch circuit is connected to the phase delay circuit to latch synchronous data from the SDRAM interface according to the delayed single-end data strobe signal.

  • Patent number: 7869093
    Abstract: A method and system reconstructs a contone image from a binary image by first tagging pixels to identify one of a multiplicity of image content types. The tag information and the pattern of bits surrounding the pixel to be converted to a contone value are used to reconstruct a contone image from a binary image. The pattern of bits in the neighborhood is used to generate a unique identifier. The unique identifier is used as the address for a lookup table with the contone value to be used. A filter also generates a contone value. A selector selects between the look-up table contone value and the filter contone value based an image context type.

  • Publication number: 20100311261
    Abstract: A universal plug adapter, comprising: a main body, at least a set of plug pins, an orientation guide rod allowing sliding of pins and a slide block restricting the shift of pins; the plug pin comprises of at least two pins of different sizes, of which a single pin can be pushed every time; a sliding groove is set laterally onto the slide block; the groove is deep upwards and shallow downwards; the pin is provided with a bulge; when the pin is pushed, the bulge moves along the groove of the slide block groove; given the different depth of the groove, the bulge pushes the slide block to shift, such that the bulges on other pins cannot be aligned with the center of the groove, so other pins not yet pushed are restricted in original position.
