  • Publication number: 20110221888
    Abstract: Provided is an imaging apparatus, method and computer-readable medium that photographs an object through at least one aperture of each of pixel of a display panel. The imaging apparatus includes a camera unit in back of the display panel and photographs the object through the at least one aperture of each of the pixels of the display panel to enable a location of the camera unit to be the same as a location of a display unit, measures a distance to the object using a blur effect occurring when photographing through the at least one aperture of the display panel, and restores an image where the blur effect is included.

  • Patent number: 7761292
    Abstract: A method and apparatus to disturb a voice signal by attenuating and masking the voice signal are provided. The method includes; receiving a voice signal from a wired or wireless network; obtaining a masked voice signal by dividing the received voice signal into a plurality of segments of the same size; outputting the received voice signal and receiving a feedback signal of the output voice signal; obtaining an attenuated voice signal by performing a first sound attenuation operation on the feedback signal; and combining the attenuated voice signal and the masked voice signal and outputting the result of the combination as disturbing sound.

  • Publication number: 20090087121
    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.
