Abstract

An image display unit operational interface for easily selecting a lot of functions while checking the content of an underlying image is provided.

In an image display control device (3) for displaying on a display unit (5) a large menu having a plurality of menu items, and an underlying image, to allow performing menu item selection and operation according to instructions by a user, a controller (14) for, according to the instructions, selecting and controlling one of either of the large menu and a small menu that has as menu items a lone portion of the menu items in the large menu, and a menu image compositor (20) for, according to control by the controller, simultaneously displaying on the display unit the small menu together with the underlying image are included.

Claims

1. An image display control device for displaying on a display unit a large menu having a plurality of menu items, and an underlying image, to allow performing menu item selection and operation according to instructions by a user, the image display control device comprising:

a controller for, according to the instructions, selecting and controlling one of either of the large menu and a small menu that has as menu items a lone portion of the menu items in the large menu; and

a menu image compositor for, according to control by the controller, simultaneously displaying on the display unit the small menu together with the underlying image.

2. An image display control device according to claim 1, wherein the controller controls the menu image compositor so as to display on the small menu different menu items in the large menu according to the instructions.

3. An image display control device according to claim 1, wherein the controller controls the menu image compositor so as to indicate, when a nondisplayed menu item adjacent to a menu item displayed on the small menu is present, the direction in which the adjacent menu item is present.

4. An image display control device according to claim 1, wherein the controller controls the menu image compositor so as to display information regarding in what position a menu item displayed in the small menu is displayed in the large menu.

5. An image display control device according to claim 1, wherein the controller controls the menu image compositor so as to change according to a predetermined condition the position of the area in which the small menu is displayed.

6. An image display control device according to claim 5, wherein the controller controls the menu image compositor so as to change the display position of the small menu area every time a predetermined time period elapses.

7. An image display control device according to claim 5, wherein the controller controls the menu image compositor so as to change the display position of the small menu area to an area excluding the central portion of the underlying image.

8. An image display control device according to claim 5, wherein the controller controls the menu image compositor so as to change the display position of the small menu area according to light/shadow distribution in the underlying image.

9. An image display control device according to claim 8, wherein the controller controls the menu image compositor so as to change the display position of the small menu area according to temporal variation in the light/shadow distribution in the underlying image.

10. An image display control device according to claim 1, wherein, when the small menu is displayed, the menu image compositor halftones an area in which the area including the menu items included in the small menu is excluded from the large menu display area, and in the halftoned area transparently displays, on the display unit, the underlying image.

11. An image display system comprising:

a display unit; and

an image display control device for displaying on the display unit a large menu having a plurality of menu items, and an underlying image, to allow performing menu item selection and operation according to instructions by a user;

wherein

the image display control device comprises;

a controller for, according to the instructions, selecting and controlling one of either of the large menu and a small menu that has as menu items a lone portion of the menu items in the large menu; and

a menu image compositor for, according to control by the controller, simultaneously displaying on the display unit the small menu together with the underlying image.
