Claim Text:
1. A motion vector correction device comprising: a circuitry that corrects the first motion vector to decrease the magnitude of first motion vector when the magnitude of first motion vector exceeds a first threshold, wherein when the magnitude of first motion vector exceeds the first threshold, the circuitry decreases the magnitude of first motion vector within a range where the magnitude of first motion vector is larger than the first threshold such that a decrement amount of the magnitude of first motion vector increases as a value between the magnitude of first motion vector and the first threshold increases, and outputs the result as a second motion vector, when the magnitude of second motion vector exceeds a second threshold, the circuitry keeps the magnitude of second motion vector unchanged from the second threshold to a third threshold larger than the second threshold, and outputs the result as a third motion vector, and when the magnitude of second motion vector exceeds the third threshold, the circuitry decreases the magnitude of second motion vector within a range where the magnitude of second motion vector is smaller than the second threshold such that a decrement amount of the magnitude of second motion vector increases as a value between the magnitude of second motion vector and the third threshold increases, and outputs the result as a third motion vector.
