the controller makes the video file of the menu image replayed on the screen of the display so as to make the positions of the selection items changed.

3. The display apparatus according to claim 1 , wherein the generating unit generates a plurality of the menu images in which the selection items are arranged at different positions within a certain area, and

the controller makes the menu images be displayed on the screen of the display while switching the plurality of the menu images so as to make the positions of the selection items changed.

4. The display apparatus according to claim 1 , wherein the generating unit generates the menu image on the basis of combination of images for each of the selection items that is individually generated, and

the controller sets arrangement positions of the selection items of which the number is the same or more as the number of the selection items, and sequentially switches the selection items to be displayed at each of the arrangement positions so as to make the positions of the selection items changed.

5. The display apparatus according to claim 1 , wherein the controller makes a change speed of the positions of the selection items dynamically changed.

6. The display apparatus according to claim 1 , wherein, when one of the linearly arranged selection items is selected, selection items of the further lower layer are arranged in a circular pattern with a position of the selected selection item as a new center.

7. The display apparatus according to claim 1 , wherein

when a second selection is made from the selection items of the lower layer that are linearly arranged, a first menu of the selection extends linearly to one of a left direction and a right direction of the selection items of the lower layer that are linearly arranged,

when a third selection is made from the first menu that extends linearly, a second menu extends linearly to one of a left direction and a right direction of the first menu, and

the first menu and the second menu extend in the left and right directions alternately.

8. The display apparatus according to claim 1 , wherein

the controller displays the menu image on the screen so that the positions of the selection items in the menu image are dynamically changed in front of a plurality of users that surround the display apparatus such that selection of the selection items can be made from different directions around the display screen, and

the controller positions the selection items arranged in the circular pattern dynamically, such that every selection item comes to a front side of each user for a certain interval of time.

9. A non-transitory computer readable medium storing a program causing a computer to execute a process for image processing, the process comprising:

generating a menu image in which selection items of a menu are geometrically arranged; and

making the menu image be displayed on a screen of a display, and making positions of the selection items in the menu image dynamically changed,

the process further comprising:

generating the menu image separately for each layer of the menu set in a hierarchy,

making the menu image of a lower layer be displayed on the screen of the display when the selection item associated with the lower layer is selected among the selection items comprised in the displayed menu image, and makings the menu image of a higher layer from which the selection item was selected be displayed in a manner that indicates that selection items of the higher layer are not currently selectable, and

recognizing a position of an object image displayed on the screen of the display, and determining a display position of the menu image so as not to overlap the object image with the menu image, wherein

the selection items are arranged in a circular pattern,

the positions of the selection items arranged in the circular pattern are rotated and moved around a center of the circular pattern,

when the lower layer is displayed, a rotation of the menu image of the higher layer than the layer that is displayed at the last is stopped, and

when one of the circularly arranged selection items is selected, selection items of the lower layer are linearly arranged with the selected selection item as a base point, and

the menu image is displayed at the determined display position.

10. The non-transitory computer readable medium according to claim 9 , wherein

the menu image is generated as a video file where the selection items are rotated and moved on a predetermined circumference, and

the video file of the menu image is replayed on the screen of the display so as to make the positions of the selection items changed.

11. The non-transitory computer readable medium according to claim 9 , wherein a plurality of the menu images are generated in which the selection items are arranged at different positions within a certain area and

the menu images are displayed on the screen of the display while switching the plurality of the menu images so as to make the positions of the selection items changed.

12. The non-transitory computer readable medium according to claim 9 , wherein the menu image is generated on the basis of combination of images for each of the selection items that is individually generated, and

arrangement positions of the selection items of which the number is the same or more as the number of the selection items are set, and the selection items to be displayed at each of the arrangement positions are sequentially switched so as to make the positions of the selection items changed.

13. The non-transitory computer readable medium according to claim 9 , a change speed of the positions of the selection items is dynamically changed.

14. The non-transitory computer readable medium according to claim 9 , wherein, when one of the linearly arranged selection items is selected, selection items of the further lower layer are arranged in a circular pattern with a position of the selected selection item as a new center.

15. The non-transitory computer readable medium according to claim 9 , wherein:

when a second selection is made from the selection items of the lower layer that are linearly arranged, displaying a first menu of the selection extending linearly to one of a left direction and a right direction of the selection items of the lower layer that are linearly arranged,

when a third selection is made from the first menu that extends linearly, displaying a second menu extending linearly to one of a left direction and a right direction of the first menu, and

the first menu and the second menu extend in the left and right directions alternately.
