Patent number: 9350975Abstract: A display apparatus and a method for applying an OSD applying thereto. The display apparatus maintains the depth of the OSD to be displayed on the screen at a specific depth if the depth of a 3D image is adjusted. Accordingly, even if the depth of the 3D image is adjusted, the depth of the OSD remains the same. Therefore, a user may be provided with the OSD of which depth does not change even if the depth of the 3D image is adjusted.Type: GrantFiled: April 1, 2011Date of Patent: May 24, 2016Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ohjae Kwon, Young-wook Sohn, Lei Zhang

Patent number: 7555166Abstract: Disclosed is an apparatus and method for compensating for estimated motion vectors by deciding whether a pattern image exists in target blocks for motion estimation. A motion estimation part compares a current block of a current frame/field to a search area established in a previous frame/field, calculates plural motion estimation error values, and estimates a temporary motion vector of the current block based on the plural motion estimation error values. A pattern decision part analyzes the calculated motion estimation error values, and decides that the current block is a pattern image. A motion compensation part produces a compensation motion vector of the current block by use of the plural motion estimation error values if the current block is decided as the pattern image. A motion vector selection part selects a final motion vector based on a result of the pattern decision part.Type: GrantFiled: July 12, 2004Date of Patent: June 30, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-hee Lee, Ohjae Kwon
