Apparatus, method, and computer program product for detecting motion vector and for creating interpolation frame

摘要

An apparatus (10, 12) for creating an interpolation frame (300) includes a first computing unit (104) that computes a first motion vector (MV1) in relation to a first block (210) in a first reference frame (200), a second extracting unit (108) that extracts a second block (410) in a second reference frame (400) based on the first motion vector (MV1), a first calculating unit (110) that calculates a correlation between the first block (210) and the second block (410), a third extracting unit (120) that extracts a third block (430a, 430b, 430c) that is shifted from the second block (410) by a certain number of pixels, a second calculating unit (122) that calculates a correlation between the first block (210) and the third block (430a, 430b, 430c), and a third computing unit (140) that computes a motion vector for an interpolation block (310) based on a most-highly correlated block-pair.
