Display control apparatus, display control method, and program for controlling the display of images in a stacked configuration

1. An information processing apparatus comprising:

a processor that

controls a display to display representative images of a plurality of content items in a stacked configuration;

assigns movement to the representative images displayed in accordance with positions of the representative images in a stacking direction of the stacked configuration;

defines a group display region displaying an image group made up of the representative images of some of the plurality of content items;

when a change to the image group displayed in the group display region has been indicated, moves the representative images that compose a new image group to the group display region having assigned delays in accordance with respective positions of the representative images in the stacking direction, and

wherein at least some of the representative images are moved over a path that is curved to an extent determined by the respective positions of the representative images in the stacking direction.

2. The information processing apparatus of claim 1 , wherein the representative images are thumbnail images.

3. The information processing apparatus of claim 2 , further comprising:

a memory that stores a plurality of groups and content corresponding to each of the plurality of groups, wherein the processor generates the thumbnail images based on the stored content corresponding to each of the plurality of groups.

4. The information processing apparatus of claim 1 , wherein the stacking direction defines a foreground and a background, and wherein representative images in the foreground are displayed to at least partially overlap representative images displayed in the background.

5. The information processing apparatus of claim 1 , wherein the stacking direction defines a foreground and a background, and wherein the processor controls the display to display representative images in the foreground at a first size and representative images in the background at a second size, which is different from the first size.

6. The information processing apparatus of claim 5 , wherein the first size is greater than the second size.

7. The information processing apparatus of claim 5 , wherein the second size is greater than the first size.

8. The information processing apparatus of claim 1 , wherein the stacking direction defines a foreground and a background, and wherein the processor assigns a first amount of movement to representative images displayed in the foreground and a second amount of movement to representative images displayed in the background, the second amount of movement being different from the first amount of movement.

9. The information processing apparatus of claim 8 , wherein the second amount of movement is greater than the first amount of movement.

10. The information processing apparatus of claim 1 , wherein at least some of the representative images are moved over a first path that is a straight line.

11. The information processing apparatus of claim 1 , wherein the processor controls the display to display each of plurality of representative images corresponding to each of a plurality of groups in a list configuration.

12. The information processing apparatus of claim 11 , wherein the processor scrolls a plurality of representative images corresponding to each of the plurality of groups in the list.

13. The information processing apparatus of claim 12 , further comprising:

an interface that receives an instruction to scroll the plurality of representative images corresponding to each of the plurality of groups in the list.

14. The information processing apparatus of claim 1 , wherein the processor controls the display to move the plurality of representative images in a first direction and delay movement of representative images displayed closer to a direction of the first direction by a first amount of time and controls the display to delay movement of representative images displayed closer to a direction opposite the first direction by a second amount of time which is different from the first amount of time.

15. A method performed by an information processing apparatus, the method comprising:

controlling, by a processor of the information processing apparatus, a display to display representative images of a plurality of content items in a stacked configuration;

assigning, by the processor, movement to the representative images displayed in accordance with positions of the representative images in a stacking direction of the stacked configuration;

defining, by the processor, a group display region displaying an image group made up of the representative images of some of the plurality of content items;

when a change to the image group displayed in the group display region has been indicated, moving, by the processor, the representative images that compose a new image group to the group display region having assigned delays in accordance with respective positions of the representative images in the stacking direction, and

wherein at least some of the representative images are moved over a path that is curved to an extent determined by the respective positions of the representative images in the stacking direction.

16. A non-transitory computer-readable medium including computer-program instructions, which when executed by an information processing apparatus, cause the information processing apparatus to perform a method comprising:

controlling a display to display representative images of a plurality of content items in a stacked configuration;

assigning movement to the representative images displayed in accordance with positions of the representative images in a stacking direction of the stacked configuration;

defining a group display region displaying an image group made up of the representative images of some of the plurality of content items;

when a change to the image group displayed in the group display region has been indicated, moving the representative images that compose a new image group to the group display region having assigned delays in accordance with respective positions of the representative images in the stacking direction, and

wherein at least some of the representative images are moved over a path that is curved to an extent determined by the respective positions of the representative images in the stacking direction.
