Filed: 2001-11-14
Abstract: PURPOSE: A method for detecting a motion using a hierarchical block base in a DVR is provided to detect the accurate motion without having extra hardware for detecting the motion. CONSTITUTION: Multiple resolution subband images are obtained by Wavelet transformation method. The multiple resolution subband images are divided into low frequency component bands and high frequency component bands. A motion of a block of a frame k is decided by finding out a position of a similar block in a frame k+1. A block matching process is continuously performed every level starting from images having low resolution. In low resolution, relatively large blocks(8,11) are used to detect positions. Therefore, a motion detected in the low resolution is used as an initial value of motion detection of high resolution. In the high resolution, the sizes of blocks(7,10) are reduced to more accurately control the detected motion. In the highest resolution, the sizes of blocks(6,9) are reduced maximally to detect the best accurate motions(601,901).

CONSTITUTION: The apparatus for manufacturing laminated material includes: heating unit which preheats a substrate(3); a T-die(2) which extrudes molten thermoplastic resin as a resin film(10); cutting unit which forms a laminating film by cutting ear portions(12) of the resin film(10) before lamination; lamination rolls which laminate the laminating film formed by cutting to the substrate(3); and a cooling device which quenches the formed laminated material.

Abstract: PURPOSE: A device and method for converting a scanning format are provided to adaptively change a scanning format of a macro block to reduce the quantity of calculations. CONSTITUTION: A scanning format converting device includes an intra-field interpolator(320), a motion compensator(340), and a data providing unit(310). The intra-field interpolator generates the second field from spatial-axis pixels of the first field of an input macro block to change a scanning format. The motion compensator converts the scanning format using the motion vector of the input macro block. The data providing unit adaptively decides a scanning format mode of the macro block on the basis of mode information and picture type of the macro block and the motion vector decoded, and then selectively provides the macro block to the intra-field interpolator and motion compensator.
