Abstract

An image processing apparatus includes: a display which displays an image through at least one screen; a processor which processes the image to be displayed on the display; a pointer adjuster which adjusts a pointer to select at least two points on the image displayed on the display; and a controller which sets a selection area by selecting a partial image displayed within a boundary including the at least two points from the image displayed on the display, and controls the processor to display the selection area on a predetermined region of the display.

Claims

1. An image processing apparatus comprising:

a processor which processes a first image corresponding to a first channel to be displayed;

a display which displays the first image on a first screen;

a pointer adjuster which adjusts a pointer to select at least two points on the first image displayed on the first screen; and

a controller which sets a selection area by selecting a partial image displayed within a boundary including the at least two points from the first image displayed on the first screen, controls a user interface generator to generate a display setup menu for setting whether to display the selection area on a region of the first screen and to display the display setup menu on the first screen, and controls the processor to display the selection area as a second screen on the region of the first screen if the display setup menu is selected to display the selection area,

wherein when the first channel is changed to a second channel, the controller controls the processor to display a second image corresponding to the second channel on the first screen while displaying the selected partial image of the first image on the second screen, and

wherein the controller controls the user interface generator to generate a display adjustment menu for adjusting the selection area displayed as the second screen if the pointer is positioned on the second screen.

2. The image processing apparatus according to claim 1, wherein the display adjustment menu includes a position adjusting menu to adjust a display position of the second screen.

3. The image processing apparatus according to claim 1, wherein the display adjustment menu includes a signal shifting menu to make the first and second screens interchange images displayed thereon with each other.

4. The image processing apparatus according to claim 1, wherein the display adjustment menu includes a screen changing menu to display an image of the second screen on the first screen.

5. The image processing apparatus according to claim 1, wherein the pointer adjuster selects the at least two points by dragging and dropping the pointer.

6. The image processing apparatus according to claim 5, wherein the pointer adjuster comprises a pointing device.

7. The image processing apparatus according to claim 6, further comprising:

a receiver which is configured to receive different video signals corresponding to different channels including the first channel and the second channel; and

a channel selector which is configured to change the first channel to the second channel,

the first screen and the second screen.

8. An image processing apparatus comprising:

a processor which processes a first image corresponding to a first channel to be displayed;

a display which displays the first image on a first screen;

a pointer adjuster which drags and drops a pointer to select a part of the first image displayed on the first screen; and

a controller which sets a partial image of the first image, selected by dragging and dropping the pointer, as a selection area, controls a user interface generator to generate a display setup menu for setting whether to display the selection area on a region of the first screen and to display the display setup menu on the first screen, and controls the processor to display the selection area as a second screen on the region of the first screen if the display setup menu is selected to display the selection area,

wherein when the first channel is changed to a second channel, the controller controls the processor to display a second image corresponding to the second channel on the first screen while displaying the selected partial image of the first image on the second screen, and

wherein the controller controls the user interface generator to generate a display adjustment menu for adjusting the selection area displayed as the second screen if the pointer is positioned on the second screen.

9. A method of controlling an image processing apparatus with a display to display an image, the method comprising:

receiving at least one video signal;

processing and outputting the received video signal to the display;

dragging and dropping a pointer to select a part of a first image of the video signal displayed on a first screen of the display;

setting a partial image of the first image, selected by dragging and dropping the pointer, as a selection area;

generating a display setup menu for setting whether to display the selection area on a region of the first screen and displaying the display setup menu on the first screen;

displaying the selection area as a second screen on the region of the first screen if the display setup menu is selected to display the selection area; and

generating a display adjustment menu for adjusting the selection area displayed as the second screen and displaying the display adjust menu on the first screen if the pointer is positioned on the second screen,

wherein when a first channel corresponding to the first image is changed to a second channel, the displaying further comprises displaying a second image corresponding to the second channel on the first screen while displaying the selected partial image of the first image on the second screen.

10. A method of controlling an image processing apparatus with a display to display an image, the method comprising:

receiving at least one video signal;

processing and outputting the received video signal to the display;

adjusting a pointer to select at least two points on a first image of the received video signal displayed on a first screen of the display;

setting a selection area by selecting a partial image displayed within a boundary including the at least two points from the first image displayed on the first screen;

generating a display setup menu for setting whether to display the selection area on a region of the first screen and displaying the display setup menu on the first screen;

displaying the selection area as a second screen on the region of the first screen if the display setup menu is selected to display the selection area; and

generating a display adjustment menu for adjusting the selection area displayed as the second screen and displaying the display adjustment menu on the first screen if the pointer is positioned on the second screen,

wherein when a first channel corresponding to the first image is changed to a second channel, the displaying further comprises displaying a second image corresponding to the second channel on the first screen while displaying the selected partial image of the first image on the second screen.

11. The method according to claim 10, further comprising adjusting a display position of the second screen.

12. The method according to claim 10, further comprising interchanging an image displayed on the first screen with an image displayed on the second screen.

13. The method according to claim 10, further comprising displaying an image of the second screen on the first screen.

14. The method according to claim 10, wherein the at least two points are selected by dragging and dropping the pointer.

15. The method according to claim 14, wherein the at least two points are selected by a pointing device.
