An example of an image display system includes a goggles apparatus and is capable of setting an angle of view of a virtual camera to a first angle of view or a second angle of view smaller than the first angle of view. If the angle of view of the virtual camera is set to the second angle of view, the image display system generates an image for a left eye and an image for a right eye in each of which a part of the virtual space is enlarged, and displays the enlarged images for a left eye and for a right eye on a display of the goggles apparatus such that display areas of the enlarged images for a left eye and for a right eye are smaller than display areas if the angle of view of the virtual camera is set to the first angle of view.
