Abstract:
An apparatus for displaying a video image, comprising:image display means for displaying an attentional subject in an attentional area in the video image;control means for moving the perspective of the video image in the direction in which the attentional subject moves in the video image, and moving the perspective of the video image and the attentional area so that said attentional subject will be located in a rear position opposite to said direction in which the attentional subject moves when said attentional subject is about to move out of said attentional area;coordinate transforming means for transforming coordinates of the attentional subject in a three-dimensional coordinate system into coordinates thereof in a plane field-of-view coordinate system;coordinate holding means for holding coordinates of the attentional subject transformed by said coordinate transforming means before and after the attentional subject moves;image display control means for displaying the attentional subject according to the coordinates transformed by said coordinate transforming means, together with a predetermined image, in the video image;decision means for deciding whether the attentional subject has moved out of said attentional area in the video image; andcalculating means for calculating a direction in which the attentional subject has moved based on the coordinates held by said coordinate holding means, if the attentional subject has moved out of said attentional area; and image perspective moving means for controlling said image display control means to move the perspective of the video image and the attentional area so that the attentional subject will be located in the rear position opposite to the direction calculated by said calculating means.
