An image of a virtual object is generated in accordance with a position and orientation of a first display device. In a case where a first mode is set, the generated image of the virtual object is displayed on a first display device and second display device. In a case where a second mode different from the first mode is set, a still image of the virtual object is displayed on the second display device. A portion of the virtual object in the still image is selected based on an instruction input by a user observing the second display device during display of the still image of the virtual object. An image of the virtual object displayed on the second display device is updated based on the selected portion of the virtual object.
