Abstract
A frame interpolation device includes: a unit dividing two temporally different reference frames of moving image signal into block units; a unit detecting motion vectors in block units in accordance with correlation between blocks of the reference frames; a unit obtaining at least first and second motion vectors from the statistical amount of the motion vectors; a unit estimating the first or second motion vector for each block in accordance with the obtained first and second motion vectors; a unit translating the first and second motion vectors through a generated pixel in an interpolated frame between the reference frames, setting local areas at four points of the start and end points of the first and second motion vectors as search areas, and identifying the first or second motion vector from the search areas; and a unit performing motion compensation on the pixel by using the first or second motion vector.
