Abstract: An encoding method is performed by an encoding apparatus, and the encoding method includes a step in which an image of an object captured by a camera in a plurality of frames of a moving image is analyzed and it is determined whether camera parameters relating to an intrinsic matrix of the camera are invariable, a step in which, when the camera parameters are invariable, six parameters representing destinations of three points for a projective transformation unit of the image of the object are generated, and a homography matrix is generated on the basis of the six parameters, and a step in which projective transformation is performed on the projective transformation unit of the image of the object using the homography matrix, and a prediction signal of the image of the object is generated on the basis of the result of the projective transformation.
