The invention relates to an image processing apparatus and method capable of improving an encoding efficiency. A reference block B which can correspond to a target block A by an inter-motion vector MV is calculated in a reference frame through a motion prediction process. Next, a block A′corresponding to the target block A is detected in a target frame through in-screen prediction and a block B′corresponding to a reference block B is detected in a reference frame. A difference between the pixel value of the target block A and the pixel value of the block A′and a difference between the pixel value of the reference block B and the block B′are calculated. Secondary difference information which is a difference between the above differences is generated, encoded, and transmitted to a decoding side. The invention is applicable to an image encoding apparatus performing an encoding process in accordance with, for example, the H.264/AVC scheme.
