Title: Apparatus and method for converting frame rate
Inventor: SON YEONG UK
IPC: H04N5/44
Filed: 2002-12-26
Abstract: PURPOSE: A frame rate converting apparatus and method are provided to eliminate blocking artifact at a block boundary. CONSTITUTION: A frame rate converting apparatus includes a motion estimator(200-1) and a motion compensator(200-2). The motion estimator estimates a motion vector of a reference block having a little matching error from a reference block of a previous input image and a search region of the current image. The motion compensator checks ununiformity of the motion vector of the reference block and surrounding motion vectors and detects a pixel difference value at a position to which the reference block is moved in the search region and a pixel error value input from the outside to judge whether the entire image has a pixel error. The motion compensator counts the number of errors within a predetermined window and outputs a newly synthesized image by using a weight of a compensation value according to a normal motion vector and a weight of a pixel average value of two continuous input images, which are different from each other.

Abstract: PURPOSE: A novel mutant stain, Agrobacterium sp. beta 82(KCTC 10099BP), producing water-soluble polysaccharide, water-soluble polysaccharide produced thereby and a producing method thereof are provided. The water-soluble polysaccharide has immunological enhancement activity and anticancer activity. Therefore, it can be used in health foods, food additives, cosmetics and diet foods. CONSTITUTION: The mutant strain. Agrobacterium sp. beta 82(KCTC 10099BP), produces water-soluble polysaccharide. The method for producing the water-soluble polysaccharide comprises culturing Agrobacterium sp. beta 82(KCTC 10099BP) at pH 6.5 to 7.5 for 48 hours, wherein the water-soluble polysaccharide produced has immunological enhancement activity and anticancer activity, and is water-soluble glucan consisting of glucose, galactose and mannose in a ratio of 5.8:6.7:1.0.
