Publication number: 20150063452Abstract: Disclosed is a residual signal inter-channel intra prediction encoding method between a residual signal of a luminance component of an image and a residual signal of a chrominance component thereof. It is possible to improve an intra prediction encoding performance when the inter-channel prediction is performed between residual signal of the luminance component and the chrominance component of HEVC, and derive a prediction coefficient for linear prediction at a high speed while the quadtree block structure of the HEVC is not changed. In addition, it is advantageous to avoid degradation in inter-channel prediction performance, which is caused when quadtree block structures of prediction units (PUs) of the luminance component and the chrominance component are different.Type: ApplicationFiled: June 13, 2014Publication date: March 5, 2015Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Ig Kyun KIM, Kyung Jin BYUN, Nak Woong EUM

Patent number: 7464275Abstract: Provided is an apparatus for controlling multiple powers which is capable of turning on and off the multiple powers in their priorities for systems or components to be supplied with the multiple powers such as a liquid crystal display (LCD) module. In the apparatus for controlling multiple powers, an on-signal of high level is applied to an input terminal, and an output of a control signal generating unit is sequentially changed to a high level whenever a clock is applied to a clock signal input terminal by one period, so that outputs of the multiple powers are sequentially output. In addition, an off signal of low level is applied to the input terminal, and an output of the control signal generating unit is changed to a low level in a reversal order whenever a clock is applied to the clock signal input terminal by one period, so that outputs of the multiple powers are interrupted in the reversal order.Type: GrantFiled: August 26, 2005Date of Patent: December 9, 2008Assignee: Electronics and Telecommunications Research InstituteInventors: Tae Young Lim, Han Jin Cho, Soon Il Yeo, Ig Kyun Kim, Kyoung Seon Shin, Hee Bum Jung

Patent number: 6907074Abstract: An apparatus and a method for performing mixed motion estimation based on a hierarchical search are provided. In the method, motion vectors of previous image data are received. The median value of the motion vectors is obtained. Current image data is received.
