Abstract
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 in the first frame image 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 in the first frame image with an area obtained by shifting the block in the second frame image by an amount of the motion vector.
