Patent ID: 8669919

Claim:
A head mounted display device comprising: an image display that is mounted on the head of a user to permit the user to visually recognize an image; an imager that takes an image in a direction of a field of view of the user and generates a taken moving image; a processor configured to execute instructions grouped into functional units, the instructions including: a unitary display image data acquisition unit that acquires unitary display image data which is to be displayed on the image display; a unitary moving image display that generates a unitary moving image correlated with the unitary display image from the moving image generated by the imager for each of the unitary display images which are displayed on the image display; a determination unit that, when any other unitary moving image correlated with the same unitary display image corresponding to one of the unitary moving images is generated, determines whether to replace the one of the unitary moving images with the any other unitary moving image; and a continual moving image display that, when the determination unit determines that the one of the unitary moving images should be replaced with the any other unitary moving image, replaces the one of the unitary moving image and combines unitary moving images that are not replaced and any other unitary moving image to generate coherent continual moving image.
