摘要： PROBLEM TO BE SOLVED: To provide technology for converting a frame rate of a panned image wherein input images entirely move, with high quality.
SOLUTION: In a frame rate conversion process, an interpolation frame is created by performing interpolation process using an image (object) motion vector detected from a plurality of frames in an input image signal and then inserted in the input image signal frame sequence. When the input image is the panned image, the interpolation process is performed using a global vector indicating a direction of the overall movement of a screen instead of the motion vector in a region including ends of the image.
