    • Provided are a motion estimation device and method adaptive to change in illumination. The motion estimation method includes the steps of: generating a current frame pattern block for a current frame block and a reference frame pattern block for a reference frame block; calculating the sum of absolute differences (SAD) for candidate pattern blocks corresponding to the current frame pattern block among the reference frame pattern blocks and determining the candidate pattern block corresponding to the SAD satisfying a predetermined condition among the calculated SADs as a motion vector; encoding the current frame block, by generating a residual signal using a difference signal between the candidate pattern block corresponding to the motion vector and the current frame pattern block then performing discrete cosine transform and quantization to the residual signal with a predetermined encoding mode; and adding flag information indicating the addition of a mean pixel value applied to the encoded current frame block and identification information on the encoding mode as header information corresponding to the encoded current frame block. By omitting insertion of a mean pixel value for some fields, it is possible to minimize the amount of bit streams transmitted to a decoder.
    • 提供了适应于照明变化的运动估计装置和方法。 运动估计方法包括以下步骤:产生用于当前帧块的当前帧模式块和用于参考帧块的参考帧模式块; 计算与参考帧图案块中的当前帧图案块相对应的候选图案块的绝对差(SAD)之和,并将所计算的SAD中满足预定条件的SAD对应的候选图案块确定为运动矢量; 通过使用与运动矢量相对应的候选模式块与当前帧模式块之间的差信号产生残差信号,然后以预定编码模式对剩余信号执行离散余弦变换和量化,对当前帧块进行编码; 以及添加指示将加到编码的当前帧块上的平均像素值的加法和编码模式的识别信息相加的标志信息作为与编码的当前帧块相对应的标题信息。 通过省略对某些场的平均像素值的插入,可以最小化发送到解码器的比特流的量。
