    摘要： Methods and apparatus for video frame rate conversion are disclosed. In one aspect of the invention, a basic interpolation motion vector for an interpolated frame is generated using a motion vector of a current frame. The motion vector of the current frame is compared with a motion vector of a previous frame. The basic interpolation motion vector is offset and corrected according to a comparison result. The interpolated frame is generated by performing motion compensation using at least one of the basic interpolation motion vector and the corrected basic interpolation motion vector.

    摘要： Disclosed is an intelligent display method for a multimedia mobile terminal. The method includes the steps of determining a type of a camera shot existing in a sport game video; deciding a region of interest within an image frame of the sport game video when it has been determined that the camera shot is a long-distance shot, magnifying the region of interest, and displaying the region of interest on the mobile terminal, and displaying the entire image frame on the mobile terminal when it has been determined that the video shot is a non-long-distance shot. The method enables the user to watch images in a more understandable and comfortable manner.

    摘要： An apparatus for determining an encoding mode in an H.264 encoder is provided with a 16×16 macroblock number calculating unit and a threshold updating unit. The 16×16 macroblock number calculating unit calculates means of the number of 16×16 macroblocks. The threshold updating unit compares the number of 16×16 macroblocks of a frame, which is chosen to be currently encoded, with the mean of the number of 16×16 macroblocks among or within the frames, and updates a currently set threshold according to a result of comparing. Then, calculating unit checks the number of times by which the encoding mode is determined by the 16×16 macroblock in a frame whose encoding is currently completed, and the threshold updating unit compares the number of times with the currently set threshold to increase or decrease the threshold according to a result of the comparison.

    摘要： A method and apparatus for estimating the contour of a user object in a moving picture during video communications so that a personal background image is not provided during video communications. Information about center coordinates as well as a size of a face of the user object is extracted from a moving picture frame. Edges are extracted from the moving picture frame, and a boundary of a head of the user object is estimated using a semicircle. The boundaries of left and right shoulders and left and right arms of the user object are estimated using second-order function graphs that overlap a largest portion of the edges. An entire contour of the user object is estimated according to the boundaries of the head, the left and right shoulders, and the left and right arms of the user object.
