The second object on the second display screen corresponds to the first object on the first display screen, and is at a different level in a hierarchy from the first object on the first display screen. ## Claims ### Claim 1 A display control device, comprising: a controller configured to: determine a first plurality of levels in a hierarchy based on a first display area of a first display screen and a second display area of a second display screen; control display of a first object on the first display screen and a second object on the second display screen, wherein the second object on the second display screen is associated with the first object on the first display screen; and control display of transition content on the second display screen, wherein the display of the transition content is controlled based on a comparison of the first display area and the second display area, wherein the transition content shows an association between the first object on the first display screen and the second object on the second display screen, and wherein the transition content shows content that is in an intermediate display mode between a first display mode of the first object and a second display mode of the second object. ### Claim 2 (depends on 1) The display control device of claim 1, wherein the first object on the first display screen is at a higher level in the hierarchy than a plurality of objects displayed on the second display screen, and wherein the first object on the first display screen corresponds to the plurality of objects displayed on the second display screen. ### Claim 3 (depends on 1) The display control device of claim 1, wherein the second object on the second display screen is at a lower level in the hierarchy than the first object on the first display screen. ### Claim 4 (depends on 1) The display control device of claim 1, wherein the controller is further configured to increase an amount of information displayed on the second display screen, wherein the amount of information is increased based on the second display area of the second display screen that is larger than the first display area of the first display screen. ### Claim 5 (depends on 1) The display control device of claim 1, wherein the controller is further configured to adjust a size of the first object on the first display screen. ### Claim 6 (depends on 1) The display control device of claim 1, wherein the first object displayed on the first display screen is of a topmost level in the hierarchy. ### Claim 7 (depends on 1) The display control device of claim 1, wherein the controller is further configured to control display of third objects of a second plurality of levels in the hierarchy on the second display screen. ### Claim 8 (depends on 1) The display control device of claim 1, wherein an amount of information displayed on the second display screen is based on display information of the second display screen. ### Claim 9 (depends on 8) The display control device of claim 8, wherein the display information includes the second display area of the second display screen. ### Claim 10 (depends on 1) The display control device of claim 1, further comprising: a first display device including the first display screen, wherein the second display screen is included in a second display device external to the first display device. ### Claim 11 (depends on 1) The display control device of claim 1, wherein the controller is further configured to control concurrent display of the first object on the first display screen and the second object on the second display screen. ### Claim 12 (depends on 1) The display control device of claim 1, further comprising an imaging element. ### Claim 13 (depends on 1) The display control device of claim 1, wherein the controller includes a processor. ### Claim 14 (depends on 1) The display control device of claim 1, wherein the controller is further configured to control the display of the first object and the second object such that a fade out of the first object on the first display screen and an appearance of the second object on the second display screen occur concurrently. ### Claim 15 (depends on 1) The display control device of claim 1, wherein the first object on the first display screen and the second object on the second display screen have a same shape. ### Claim 16 (depends on 1) The display control device of claim 1, wherein the first object on the first display screen and the second object on the second display screen have a same color. ### Claim 17 (depends on 1) The display control device of claim 1, wherein the second object on the second display screen is displayed within a third object corresponding to the first object on the first display screen. ### Claim 18 A display control method, comprising: determining, by a processor, a first plurality of levels in a hierarchy based on a first display area of a first display screen and a second display area of a second display screen; controlling, by the processor, display of a first object on the first display screen and a second object on the second display screen, wherein the second object on the second display screen is associated with the first object on the first display screen; and controlling display of transition content on the second display screen, wherein the display of the transition content is controlled based on a comparison of the first display area and the second display area, wherein the transition content shows an association between the first object on the first display screen and the second object on the second display screen, and wherein the transition content shows content that is in an intermediate display mode between a first display mode of the first object and a second display mode of the second object. ### Claim 19 A non-transitory computer-readable medium having stored thereon, computer executable instructions for causing a computer to execute operations, the operations comprising: determining a first plurality of levels in a hierarchy based on a first display area of a first display screen and a second display area of a second display screen; controlling display of a first object on the first display screen and a second object on the second display screen, wherein the second object on the second display screen is associated with the first object on the first display screen; and controlling display of transition content on the second display screen, wherein the display of the transition content is controlled based on a comparison of the first display area and the second display area, wherein the transition content shows an association between the first object on the first display screen and the second object on the second display screen, and wherein the transition content shows content that is in an intermediate display mode between a first display mode of the first object and a second display mode of the second object.
