Abstract

A mobile terminal device includes a display part, a receiving part that receives an operation to cause an image group displayed in the display part to transition, and a display controller that controls the display part such that the image group displayed in the display part makes transition based on the operation. When the image group is caused to transition, the display controller reduces an image constituting the image group and increases the number of images displayed in the display part.

Claims

1. A mobile terminal device comprising:

a display;

a touch sensor configured to detect a touch input; and

at least one processor configured to, when the touch sensor detects a first input comprising a slide and release of a touch on an image group displayed on the display,

determine a moving speed of the first input,

after the moving speed of the first input exceeds a predetermined speed, cylindrically curve the image group in a depth direction by gradually changing a degree of the curve, so as to reduce a size of one or more images within a center of the image group, while maintaining a size of one or more images at two ends of the image group, to increase a number of images displayed within the image group on the display,

scroll the cylindrically-curved image group in accordance with the moving speed of the first input, and,

when the touch sensor detects a further touch input following the release of the first input and during the scrolling,

initially stop the scrolling and maintain the cylindrical curvature of the image group on the display, and,

until the further touch input is terminated, when the further touch input comprises a continuous slide, scroll the image group in accordance with the slide and maintain the cylindrical curvature of the image group.

2. The mobile terminal device according to claim 1, wherein the at least one processor is further configured to not cylindrically curve the image group but scroll the image group, when the moving speed of the first input is equal to or slower than the predetermined speed.

3. The mobile terminal device according to claim 1, wherein scrolling the cylindrically-curved image group in accordance with the moving speed of the first input comprises gradually decelerating a speed of the scrolling.

4. The mobile terminal device according to claim 3, wherein the at least one processor is further configured to remove the cylindrical curvature of the image group, so as to restore the size of the one or more images within the center of the image group to an original size and decrease the number of images displayed within the image group on the display when the speed of the scrolling becomes slower than a predetermined speed by the deceleration and the touch sensor does not detect the further touch input before the speed of the scrolling becomes lower than that predetermined speed.

5. The mobile terminal device according to claim 1, wherein the at least one processor controls the display such that, during scrolling of the image group, the image group appears to move along a cylindrical curved surface, which is curved about an axis perpendicular to a moving direction of the image group.

6. The mobile terminal device according to claim 1, wherein the image group includes an icon.

7. The mobile terminal device according to claim 1, wherein the image group includes a thumbnail of an electronic file.

8. The mobile terminal device according to claim 1, wherein the first input comprises a flick.

9. The mobile terminal device according to claim 3, wherein gradually decelerating a speed of the scrolling comprises, while approaching a limit of the image group, correcting the speed of the scrolling so that the scrolling does not exceed the limit of the image group.

10. The mobile terminal device according to claim 1, wherein the image group comprises a plurality of images arranged in a triangular lattice.

11. The mobile terminal device according to claim 1, wherein the image group comprises a plurality of images arranged in a hexagonal lattice.

12. The mobile terminal device according to claim 1, wherein the at least one processor cylindrically curves the image group as soon as the moving speed of the first input exceeds the predetermined speed for a predetermined time period.
