摘要：
PROBLEM TO BE SOLVED: To provide a technique for generating interpolation image by accurately detecting a scroll scene, even when an area which is difficult for detecting a motion vector is included in an image in a frame rate conversion apparatus. SOLUTION: A frame rate conversion apparatus compares a first frame image and a second frame image, detects a motion vector for each of blocks obtained by dividing a frame image into blocks, detects a scroll vector which indicates a uniform motion in an entire frame image based on the detected motion vector, and determines whether frame interpolation using the scroll vector is possible or not for each block in the first frame image, based on a correlation value in block matching of the block with an area obtained by shifting the block in the second frame image by an amount of the scroll vector, and a correlation value in block matching of the block with an area obtained by shifting the block in the second frame image by an amount of the motion vector.

要解决的问题：即使当在帧速率转换装置中的图像中包括难以检测运动矢量的区域时，通过精确地检测滚动场景来提供用于产生插值图像的技术。 解决方案：帧速率转换装置比较第一帧图像和第二帧图像，检测通过将帧图像分割成块而获得的每个块的运动矢量，检测指示整体上均匀运动的滚动向量 基于检测到的运动矢量的帧图像，并且基于块的块匹配中的相关值和通过移位块获得的区域来确定是否可以对第一帧图像中的每个块进行使用滚动向量的帧插值 在第二帧图像中以一定量的滚动向量，以及块的块匹配中的相关值与通过将第二帧图像中的块移位一定量的运动矢量而获得的区域。 版权所有（C）2011，JPO＆INPIT
