This disclosure relates to image processing apparatuses and methods for reducing the load of motion vector information coding and decoding operations that use the correlation in the temporal direction. In a coding mode, the motion vector information about a current small region is encoded by using the motion vector information about a reference small region located in the same position in a reference frame as the current small region and using the temporal correlation of the motion vector information, the current small region being formed by dividing a current partial region of a current frame image into small regions. If the reference small region is a small region not having its motion vector information stored in a motion vector information storage unit, a calculation unit calculates the motion vector information about the reference small region by using the motion vector information stored in the motion vector information storage unit. This invention can be applied to an image processing apparatus, for example.
