Abstract
A video image encoding apparatus includes an in-picture motion vector calculation unit and a vector encoding unit. The in-picture motion vector calculation unit calculates an in-picture motion vector indicating a spatial movement amount between a block to be encoded and a reference block in an encoded region in the picture to be encoded. The vector encoding unit obtains a prediction vector for predicting the in-picture motion vector of the block to be encoded based on at least one of a first in-picture motion vector calculated in a first reference available region including a block encoded before the block to be encoded is encoded and a second in-picture motion vector calculated in a second reference available region including a block in a position corresponding to the block to be encoded in an already encoded reference picture, and performs prediction encoding on the in-picture motion vector based on the prediction vector.
