摘要： 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. Motion of the current image data is compensated for based on the median value of the motion vectors. SAD values of the previous image data are received and the maximum value of the SAD values is obtained. The motion compensation result is compared with the maximum value of the SAD values. Motion estimation of the current image data is skipped and the motion compensation result is output if the motion compensation result is smaller than the maximum value of the SAD values. Motion estimation for the current image data is performed if the motion compensation result is greater than or equal to the maximum value of the SAD values, and the motion estimation result is output.

摘要： 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.
摘要翻译：本发明提供了一种用于控制多个功率的装置，其能够在要提供给诸如液晶显示器（LCD）模块的多个功率的系统或组件的优先级中打开和关闭多个功率。在用于控制多个功率的装置中，将高电平的接通信号施加到输入端，并且每当时钟被施加到时钟信号输入端时，控制信号产生单元的输出被顺序地改变为高电平一个周期，从而顺序输出多个功率的输出。此外，只要将时钟施加到时钟信号输入端子一个周期，则将低电平的关闭信号施加到输入端子，并且控制信号产生单元的输出以反转次序改变为低电平，使得多个功率的输出以反转顺序中断。
