    • A method of converting an image rate by using image scaling includes changing a resolution of an input original image sequence and generating a changed resolution image sequence; determining a first motion vector by estimating motion of a first image by using a plurality of images from the changed resolution image sequence; determining a second motion vector by modifying the first motion vector of the first image to correspond to a resolution of an original image of the original image sequence, where the original image corresponds to the first image; detecting characteristic information of the original image; determining a third motion vector corresponding to the resolution of the original image by compensating the second motion vector based on the detected characteristic information; and converting an image rate of the input original image sequence based on the detected characteristic information of the original image and the third motion vector.
    • 通过使用图像缩放来转换图像速率的方法包括改变输入原始图像序列的分辨率并生成改变的分辨率图像序列; 通过使用来自改变的分辨率图像序列的多个图像估计第一图像的运动来确定第一运动矢量; 通过修改第一图像的第一运动矢量来对应于原始图像的原始图像的分辨率来确定第二运动矢量,其中原始图像对应于第一图像; 检测原始图像的特征信息; 通过基于检测到的特征信息来补偿第二运动矢量来确定与原始图像的分辨率对应的第三运动矢量; 以及基于检测到的原始图像的特征信息和第三运动矢量来转换输入的原始图像序列的图像速率。
