摘要： An image processing apparatus includes a subsampling circuit to generate a subsampled image based on a sampling position of each frame of an input image; a control circuit to assign a frame at a sampling position which is substantially the same as a sampling position of a frame to be encoded as a reference frame based on information of the sampling position of each frame and a structure of a group of pictures; and an encoder to encode the frame to be encoded by compressing the frame to be encoded using inter-frame prediction based on a subsampled image of the frame to be encoded and the reference frame.
