  • Patent number: 8970556
    Abstract: A sensing apparatus may emit light, radiated from a light source, to an upper part and may preserve light in an internal part, based on a total internal emission angle of the light. Also, the sensing apparatus may project the light radiated to the upper part, and the light preserved in the internal part, towards at least one of a touching object and the proximate object.

  • Patent number: 8699816
    Abstract: A method to enhance detail of an image based on noise elimination includes calculating a noise weight corresponding to a probability that a center pixel, located in a block of pixels of a region of the image, is noise by using a difference between the center pixel and a surrounding pixel located in the block of pixels, calculating a first substitution value for the center pixel based on the noise weight; and calculating a second substitution value for the center pixel by using the noise weight and a sharpen filter.
