  • Publication number: 20200336717
    Abstract: An image acquisition unit 40 acquires a subject image in which a subject is positioned in front of a background with a single color. An eye gaze information determination unit 32 determines an eye direction and a viewpoint position of a user wearing an HMD and provides the eye direction and the viewpoint position for a display control unit 50. The display control unit 50 performs chroma-key composition such that the subject included in the subject image may become a foreground image with respect to a background image and thereby generates a display image according to the viewpoint position of the user. The display control unit 50 determines an orientation of the subject such that the subject may be made to face the viewpoint position of the user, in a case where the viewpoint position has been changed.
