20130070862 | VIDEO COMPRESSION ENCODING DEVICE IMPLEMENTING AN APPLIED MOTION COMPENSATION TECHNIQUE USING A SELECTIVE MOTION SEARCH, AND METHOD FOR DETERMINING SELECTIVE MOTION COMPENSATION - Disclosed is a method for generating a motion search area of a video CODEC for implementing motion compensation through motion estimation as a unit of block. Compression efficiency can be further improved by additionally creating various reference frames by an intentional motion blur and a deblur filter, filtering a motion search area using a motion blur filter and a motion deblur filter as a unit of block which is a unit of video coding, and selecting reference frame having small residual frame data during execution of the motion estimation as final reference frames among original reference frames and various reference frames (motion search areas) additionally created. | 03-21-2013 |
20130064302 | VIDEO COMPRESSION CODING DEVICE AND DECODING DEVICE APPLIED WITH MOTION COMPENSATION TECHNIQUE USING SELECTIVE REFERENCE FRAME, AND METHOD FOR DETERMINING SELECTIVE REFERENCE FRAME FOR MOTION COMPENSATION - Disclosed is a method of generating a reference frame of a video CODEC for implementing motion compensation through motion estimation. The present invention is to increase compression efficiency by additionally creating various reference frames applied to an intentional motion blur and a deblur filtering, and selecting reference frame having small residual frame data during execution of the motion estimation as final reference frames among original reference frames and various reference frames additionally created. | 03-14-2013 |
20120230425 | ENCODING APPARATUS AND METHOD OF CONVERSION BLOCK FOR INCREASING VIDEO COMPRESSION EFFICIENCY - A compression encoding method which, when performing data conversion using the fact that when data is converted into frequency components, the human eye is sensitive to components close to low frequency components and insensitive to components close to high frequency components, configures a filter in which importance is placed on DC data and its adjacent filter coefficients, calculates the cost for a conversion block which has undergone conversion and quantization, which is required for the data removal of compression encoding using the filter, determines data targets to be removed using the calculated cost and set reference values, and removes the corresponding data, thereby reducing the amount of data to be compressed and therefore increasing compression efficiency without influencing image quality. | 09-13-2012 |
