PROBLEM TO BE SOLVED: To exactly grasp display contents and to perform legible display by simple device structure, with respect to a display device used in an environment with swing or oscillation. SOLUTION: This image display device having an image memory which accepts image data which should be displayed and temporarily stores them and a display part which performs image display based on read data from the image memory is provided with an image pickup part which picks up an image of at least a part of an observer of the image display device or an image of an object at a position fixed to the observer and a movement vector calculation part which calculates a movement vector indicating relative movement and the direction of the display part and the observer based on image pickup data of the image pickup part. The relative movement of the display part and the observer is alleviated or eliminated by controlling a reading address of the image memory based on movement vector from the movement vector calculation part.
