1. An image movement vector detection apparatus for detecting an image movement vector from an image signal produced by a video camera, the image movement vector representing movement of an object within an image represented by the image signal, comprising: vibration vector detecting means for detecting a vibration vector from the image signal resulting from vibration of the video camera; and image movement vector detecting means for detecting an image movement vector representing movement of an object within an image represented by the image signal based on both the image signal and the vibration vector.
