An image display system comprising: a goggle apparatus; object placement means (20, S100) for placing an object in a virtual space which is a user interface that can be operated by a user; display control means for displaying, on a display section of the goggle apparatus, an image captured by a virtual camera in the virtual space; orientation acquisition means for acquiring an orientation of the goggle apparatus; and camera rotation means for rotating the virtual camera in the virtual space based on the orientation of the goggle apparatus; characterised by the image display system further comprising: detection means (S131, S133, S134) for detecting a change in a rotation of a line of sight of the virtual camera from a state where the line of sight of the virtual camera rotates in a first direction to a state where the line of sight of the virtual camera rotates in a second direction that is opposite to the first direction; and control means for, based on the detection by the detection means, performing a movement of the object so that at least a part of the object is located within an image capturing range of the virtual camera, wherein, in a case where the virtual camera is rotated with respect to a state where the object is displayed at the front of the virtual camera, if it is detected that the line of sight of the rotational angle of the virtual camera is reversed by a predetermined angle, the object is moved so that at least a part of the object is located within an image capturing range of the virtual camera, and if the line of sight of the virtual camera rotates in the first direction without reversing in the second direction, the control means does not perform the movement of the object. a goggle apparatus; object placement means (20, S100) for placing an object in a virtual space which is a user interface that can be operated by a user; display control means for displaying, on a display section of the goggle apparatus, an image captured by a virtual camera in the virtual space; orientation acquisition means for acquiring an orientation of the goggle apparatus; and camera rotation means for rotating the virtual camera in the virtual space based on the orientation of the goggle apparatus; characterised by the image display system further comprising: detection means (S131, S133, S134) for detecting a change in a rotation of a line of sight of the virtual camera from a state where the line of sight of the virtual camera rotates in a first direction to a state where the line of sight of the virtual camera rotates in a second direction that is opposite to the first direction; and control means for, based on the detection by the detection means, performing a movement of the object so that at least a part of the object is located within an image capturing range of the virtual camera, wherein, in a case where the virtual camera is rotated with respect to a state where the object is displayed at the front of the virtual camera, if it is detected that the line of sight of the rotational angle of the virtual camera is reversed by a predetermined angle, the object is moved so that at least a part of the object is located within an image capturing range of the virtual camera, and if the line of sight of the virtual camera rotates in the first direction without reversing in the second direction, the control means does not perform the movement of the object. detection means (S131, S133, S134) for detecting a change in a rotation of a line of sight of the virtual camera from a state where the line of sight of the virtual camera rotates in a first direction to a state where the line of sight of the virtual camera rotates in a second direction that is opposite to the first direction; and control means for, based on the detection by the detection means, performing a movement of the object so that at least a part of the object is located within an image capturing range of the virtual camera, wherein, in a case where the virtual camera is rotated with respect to a state where the object is displayed at the front of the virtual camera, if it is detected that the line of sight of the rotational angle of the virtual camera is reversed by a predetermined angle, the object is moved so that at least a part of the object is located within an image capturing range of the virtual camera, and if the line of sight of the virtual camera rotates in the first direction without reversing in the second direction, the control means does not perform the movement of the object.
