Abstract

An image display apparatus includes a display unit for displaying an image, a detecting unit for detecting a position designated by an operation of designating a position on the displayed image and a file operation unit operating a file. The display unit displays images generated from a file on page-by-page basis on a partial area of the display unit. The file operating unit operates the file in accordance with the change of position detected by the detecting unit, when, in a state in which no position has been detected by the detecting unit, a designated position outside of the prescribed partial area is first detected by the detecting unit and the designated position changes while the position designating operation is maintained and then no position is detected by the detecting unit. Thus, the user can easily and intuitively operate the displayed page image or the file.

Claims

1. An image display apparatus, comprising:

a display unit displaying an image;

a detecting unit detecting a position designated by an operation of designating a position on the image displayed by said display unit; and

a file operation unit operating a file;

wherein

said display unit displays an images generated from data contained in one file page by page on a prescribed partial area of said display unit; and

said file operation unit operates said file in accordance with the change of position detected by said detecting unit, when, in a state in which no position has been detected by said detecting unit, a designated position outside of said prescribed partial area is first detected by said detecting unit and the designated position changes while the position designating operation is maintained and then no position is detected by said detecting unit.

2. The image display apparatus according to claim 1, further comprising

a determining unit for determining, when the designated position outside of said prescribed partial area is first detected by said detecting unit in the state in which no position has been detected by said detecting unit, whether the designated position has come to be within said prescribed partial area, after the designated position changes while the position designating operation is maintained;

wherein

if it is determined by said determining unit that the designated position has come to be within said prescribed partial area, said file operating unit operates said file in accordance with a positional relation between a trajectory formed by the change of position detected by said detecting unit and said prescribed partial area.

3. The image display apparatus according to claim 1, wherein

said prescribed partial area is a rectangle;

and

information indicating said file operation is displayed in an area outside said prescribed partial area along at least one side of said rectangle.

4. The image display apparatus according to claim 1, wherein

said detecting unit includes a touch-detecting unit arranged on a display area of said display unit displaying an image, for detecting a touched position;

and

the operation of designating the position on the image displayed by said display unit is a touch operation.

5. The image display apparatus according to claim 1, wherein

said prescribed partial area is a rectangle;

and

the file operation by said file operating unit differs depending on which one of four sides of said rectangle intersects with a trajectory formed by the change of position detected by said detecting unit.

6. The image display apparatus according to claim 1, wherein

said file includes information related to an order of displaying said image displayed page by page;

and

the file operation by said file operating unit, when the direction of the change of position detected by said detecting unit while said image is displayed page by page on said prescribed partial area is a right/left direction, is an operation to change said image displayed page by page in accordance with said order of displaying.

7. The image display apparatus according to claim 1, wherein

said file includes information related to an order of displaying said image displayed page by page;

and

the file operation by said file operating unit, when the direction of the change of position detected by said detecting unit while said image is displayed page by page on said prescribed partial area is an upward/downward direction, is an operation of stopping displaying the image generated from the data contained in said file page by page, or an operation of printing the image generated from the data contained in said file page by page.

8. A method of operating an image display apparatus, comprising the steps of:

displaying an image on an entire surface of a display screen of an image display apparatus;

displaying an image generated from data contained in one file page by page on a prescribed partial area on said display screen;

detecting a position designated by an operation of designating a position on the image displayed on the entire surface of said display screen; and

operating said file in accordance with the change of position detected at said detecting step, when, in a state in which no position has been detected at said detecting step, a designated position outside of said prescribed partial area is first detected at said detecting step and the designated position changes while the position designating operation is maintained and then no position is detected.
