Image display device, image display method and information recording medium for displaying and scrolling objects on a display
View Patent ↗To provide an image display device for displaying, when displaying a plurality of display targets while scrolling, the respective display targets in a manner that takes into consideration the sizes and scroll directions of the respective display targets. An image display device places a plurality of display targets on a virtual plane, instructs the size of a display area defined on a part of the virtual plane, displays an image showing a picture inside the display area, and moves at least either one of the display targets and display area along a predetermined direction set on the virtual plane, relative to the virtual plane, in which the respective display targets are placed so as to be included in an area which is a band area extending in the predetermined direction on the virtual plane, having a width corresponding to the instructed size of the display area, and partially overlapping the display area.
1. An image display device comprising:
an image display unit for displaying an image showing at least one of a plurality of display targets;
a target changing unit for sequentially changing the display target shown by the image by scrolling the plurality of display targets automatically on the display device; and
a restriction unit for stopping, when change of an increase in magnification ratio for the display target shown by the image is instructed by a user without selecting any of the display targets, scrolling of the display target by the target changing unit according to an instructed magnification ratio,
wherein the restriction unit, when change of the magnification ratio to a value equal to or larger than a predetermined value is instructed, restricts scrolling of the display targets by the target changing unit, and
wherein the restriction unit, when change of the magnification ratio to a value smaller than the predetermined value is instructed, releases scrolling of the change of the display targets.
2. The image display device according to claim 1 , further comprising
a placing unit for placing the plurality of display targets on a virtual plane,
wherein the image display unit displays an image showing a picture inside a display area defined on a part of the virtual plane and including at least one of the plurality of display targets placed,
the target changing unit moves at least either one of the respective display targets and display area along a predetermined direction defined on the virtual plane, relative to the virtual plane, to thereby scroll the display targets, and
the restriction unit restricts the scrolling of the respective display targets or the display area relative to the virtual plane, to thereby restrict change of the display targets.
3. The image display device according to claim 2 , wherein the restriction unit moves the display area or the respective display targets to a position which is determined based on a position of the display area and the respective display targets on the virtual plane at a time of receiving the instruction, and then stops the scrolling of the display area or the respective display targets.
4. An image display device, comprising:
a unit for displaying an image showing a picture in which a plurality of display targets sequentially automatically scroll on a screen; and
a unit for stopping, when change of an increase in magnification ratio for a display target shown by the image is instructed by a user without selecting any of the display targets, scrolling of the display targets on the screen according to an instructed magnification ratio,
wherein, when change of the magnification ratio to a value equal to or larger than a predetermined value is instructed, scrolling of the display targets is restricted, and
wherein, when change of the magnification ratio to a value smaller than the predetermined value is instructed, scrolling of the change of the display targets is released.
5. An image display method executed on a device having a processor comprising:
an image display step of displaying on a display an image showing at least one of a plurality of display targets;
a target changing step of sequentially changing the display target shown by the image by automatically scrolling the plurality of display targets on the display device; and
a restriction step of stopping, when change of an increase in magnification ratio for the display target shown by the image is instructed by a user without selecting any of the display targets, scrolling of the display target at the target changing step according to an instructed magnification ratio,
wherein, when change of the magnification ratio to a value equal to or larger than a predetermined value is instructed, scrolling of the display targets is restricted, and
wherein, when change of the magnification ratio to a value smaller than the predetermined value is instructed, scrolling of the change of the display targets is released.
6. A non-transitory computer readable information storage medium storing a program for causing a computer to function as:
an image display unit for displaying an image showing at least one of a plurality of display targets;
a target changing unit for sequentially changing the display target shown by the image by automatically scrolling the plurality of display targets on the display device; and
a restriction unit for stopping, when change of an increase in magnification ratio for the display target shown by the image is instructed by a user without selecting any of the display targets, scrolling of the display target by the target changing unit according to an instructed magnification ratio,
wherein the restriction unit, when change of the magnification ratio to a value equal to or larger than a predetermined value is instructed, restricts scrolling of the display targets by the target changing unit, and
wherein the restriction unit, when change of the magnification ratio to a value smaller than the predetermined value is instructed, releases scrolling of the change of the display targets.
