Claim:
1. A video encoding method, comprising: obtaining camera movement amount data indicating an original direction and an original amount of movement of a camera; performing motion compensation on image data received from the camera, based on a motion compensation vector that indicates movement of part of an image between a preceding frame and a current frame; determining an image search range for the motion compensation based on the camera movement amount data; dividing a frame into a plurality of blocks; setting an adjusted motion vector for each block among the plurality of blocks; each adjusted motion vector including an adjusted direction and an adjusted amount of movement of the camera; and wherein each adjusted motion vector is set by adjusting a corresponding original motion vector for each block among the plurality of blocks, according to a focal length of a lens of the camera; each original motion vector including an original direction and an original amount of movement of the camera; wherein the adjusted direction of each adjusted motion vector is set by adjusting the original direction of the corresponding original motion vector, and the adjusted amount of each adjusted motion vector is set by adjusting the original amount of the corresponding original motion vector; and wherein the image search range for the motion compensation is determined based on the adjusted motion vectors.
