    摘要: One embodiment of the present invention relates to a method and a apparatus for converting a three-dimensional image using depth map information. The apparatus comprise a depth map estimation unit which estimates the depth map information for each pixel present in each frame of input image data, a depth map application unit which moves each pixel by the depth map information in the X-axis direction, a 3D image interpolation unit which, when a blank pixel occurs in the frame due to the movement, forms an interpolated pixel in the blank pixel by applying a weight to adjacent pixels of the blank pixel, and a 3D image rendering processing unit which renders a left-eye image and a right-eye image to which the interpolated pixel is applied.

    摘要: Provided is a power allocation method and apparatus for providing a packet data service in a mobile communication system is capable of reducing outage of a line service while simultaneously providing the line service and the packet service. It is checked whether or not packet data traffic to be transmitted to a specified mobile station is newly generated. If the packet data traffic is newly generated, it is checked whether or not there is the mobile station making use of the line service where a current call is in progress. If there is the mobile station making use of the line service where the current call is in progress, it is checked whether or not the packet data traffic is currently transmitted to any other mobile station. If the packet data traffic is not currently transmitted to the other mobile station, the power transmitted to the mobile station making use of a new packet data service is gradually increased by a preset increment for a preset predetermined time. Thereby, it is possible to innovatively reduce the outage of the mobile station making use of the line service while simultaneously providing the line service and the packet service as compared with the prior art.
