Abstract

There is provided an image processing apparatus which enables an image displayed on a display device to be optimally formed according to display capabilities of an information terminal, for display on the information terminal. Window information indicative of the size of a window in an image displayed on the display device is obtained form the display device. Display device information indicative of display capabilities of the information terminal is obtained from the information terminal. The image that is displayed on the display device is changed based on the window information and the display device information, and the changed image is displayed on the information terminal.

Claims

1. An image processing apparatus that is connected to a display device and an at least one information terminal, comprising:

a first information-obtaining device that obtains window information from the display device, the window information being indicative of a size of a window displayed on the display device;

a second information-obtaining device that obtains display device information from the information terminal, the display device information being indicative of display capabilities of the information terminal;

a changing device that changes size of the window displayed on the display device based on the window information and the display device information; and

a display device that causes the changed window to be displayed on the information terminal.

2. An image processing apparatus according to claim 1, wherein the window information comprises a height, a width, and coordinates of the window.

3. An image processing apparatus according to claim 1, wherein the display device information comprises a resolution of the information terminal with which the image can be displayed.

4. An image processing apparatus according to claim 1, wherein said changing device changes the size and a position of the window displayed on the display device based on a height and a width of the window and a resolution of the information terminal with which the image can be displayed.

5. An image processing apparatus according to claim 1, wherein said changing device comprises a size reduction ratio-determining device that determines a size reduction ratio by which the window displayed on the display device is reduced, based on a height and a width of the window and a resolution of the information terminal with which the image can be displayed.

6. An image processing apparatus according to claim 5, wherein said display device comprises a scroll device that scrolls a screen of the window, and wherein an amount of scroll movement of the screen carried out by said scroll device is reduced according to the size reduction ratio determined by said size reduction ratio-determining device.

7. An image processing apparatus according to claim 5, wherein when the window is reduced in size by the size reduction ratio, if a size of characters contained in the window becomes smaller than a predetermined size, said changing device changes the characters by a size reduction ratio that causes the size of the characters to be changed to the predetermined size.

8. An image processing apparatus according to claim 1, wherein said display device displays the changed window at a predetermined position in a screen displayed by the information terminal.

9. An image processing apparatus according to claim 1, wherein said changing device has a format in which a display position of the window is preset according to the display capabilities of the information terminal, and changes a layout of the window displayed on the display device based on the format.

10. An image processing apparatus according to claim 1, wherein the window comprises a plurality of windows, and said changing device changes the window such that the plurality of windows do not overlap when the plurality of windows are displayed on the information terminal.

11. An image processing method for an image processing apparatus that is connected to a display device and an at least one information terminal, comprising:

a first information-obtaining step of obtaining window information from the display device, the window information being indicative of a size and a position of a window displayed on the display device;

a second information-obtaining step of obtaining display device information from the information terminal, the display device information being indicative of display capabilities of the information terminal lay; and

a changing step of changing size of the window displayed on the display device based on the window information and the display device information; and

a display step of causing the changed window to be displayed on the information terminal.

12. An image processing method according to claim 11, wherein the window information comprises a height, a width, and coordinates of the window.

13. An image processing method according to claim 11, wherein the display device information comprises a resolution of the information terminal with which the image can be displayed.

14. An image processing method according to claim 11, wherein said changing step comprises changing the size and the position of the window displayed on the display device based on a height and a width of the window and a resolution of the information terminal with which the image can be displayed.

15. An image processing method according to claim 11, wherein said changing step comprises a size reduction ratio-determining step of determining a size reduction ratio by which the window displayed on the display device is reduced, based on a height and a width of the window and a resolution of the information terminal with which the image can be displayed.

16. An image processing method according to claim 15, wherein said display step comprises a scroll step of scrolling a screen of the window, and wherein an amount of scroll movement of the screen carried out in said scroll step is reduced according to the size reduction ratio determined in said size reduction ratio-determining step.

17. An image processing method according to claim 15, wherein when the window is reduced in size by the size reduction ratio, if a size of characters contained in the window becomes smaller than a predetermined size, said changing step comprises changing the characters by a size reduction ratio that causes the size of the characters to be changed to the predetermined size.

18. An image processing method according to claim 11, wherein said display step comprises displaying the changed window at a predetermined position in a screen displayed by the information terminal.

19. An image processing method according to claim 11, wherein said changing step uses a format in which a display position of the window is preset according to the display capabilities of the information terminal, and comprises changing a layout of the window displayed on the display device based the format.

20. A program for causing a computer to execute an image processing method for an image processing apparatus connected to a display device and an at least one information terminal, the program comprising:

a first information-obtaining module for obtaining window information from the display device, the window information being indicative of a size and a position of a window displayed on the display device;

a second information-obtaining module for obtaining display device information from the information terminal, the display device information being indicative of display capabilities of the information terminal; and

a changing module for changing size of the window displayed on the display device based on the window information and the display device information; and

a display module for causing the changed image to be displayed on the information terminal.
