According to one embodiment, an interpolated frame generator comprises first detector detects potential motion vector by block matching between input frame images, using first block of fixed size, second detector detects motion vector by block matching between the input frame images, using second block having fixed size larger than that of the first block, and generator generates interpolated frame by using the potential motion vector when first detector detects only one potential motion vector, and generates interpolated frame by using a potential motion vector closest to the motion vector detected by the second detector when first detector detects a plurality of motion vectors, wherein first detector includes extractor compares SAD of motion vector with SAD of motion vectors adjacent to the motion vector, and extracts potential motion vector having SAD smaller than any of the SAD of adjacent motion vectors, as a potential motion vector used in generator.
