  • Patent number: 8598036
    Abstract: A method for forming a fine pattern having a variable width by simultaneously using an optimal focused electron beam and a defocused electron beam in a light exposure process Includes, after forming a first film on a substrate, forming a first film pattern including a first level area and a second level area having different distances from the substrate by changing a profile of an upper surface of the first film. A photoresist film having a first area covering the first level area and a second area covering the second level area is formed. To simultaneously light-expose the first area and the second area with the same width, a light exposure condition, in which an optimal focused electron beam is eradiated on the first area and a defocused electron beam is eradiated on the second area, is applied.

  • Patent number: 8565512
    Abstract: A method, medium, and system generating a depth map of a video image are provided. The depth map generating method extracts the ground of a video image other than an object from the video image, classifies the video image as a long shot image or a non-long shot image based on a distribution value of the extracted ground, calculates a depth value gradually varied along a predetermined direction of the extracted ground when the video image corresponds to the long shot image and calculates a depth value based on the object when the video image corresponds to the non-long shot image. Accordingly, a sense of space and perspective can be effectively given to even a long shot image in which the ground occupies a large part of the image and a stereoscopic image recognizable by a viewer can be generated even if rapid object change is made between scenes in a video image.

  • Publication number: 20130250975
    Abstract: A digital broadcasting system provides a method and device for packetizing a video stream. The packetizing device includes: a video frame check block for classifying an encoded video stream according to the frame type; a header setting block for setting a packet header for each of the classified frames; and a packetizing block for packetizing a video frame on the basis of the set packet header. The frame type may be one of an intra-coded (I) frame, a predicted (P) frame, and a bi-predictive (B) frame. Since a digital broadcasting stream is efficiently packetized, overhead due to a typical synchronization packet may be reduced, and accordingly, bandwidth may be efficiently used.
