Display device for displaying multiple screens and method for controlling the same
A method for controlling a display device that displays a frame buffer on a plurality of screens is provided. The method includes receiving a multi-screen mode execution command to display a single frame buffer on a plurality of screens, acquiring the frame buffer, splitting the frame buffer into a plurality of frame buffers to correspond to the plurality of screens, setting an offset for each of the plurality of split frame buffers, and displaying each of the plurality of split frame buffers on an associated one of the plurality of screens based on the set offset.
1. A method for controlling a first display device, the method comprising:
acquiring an image and a split boundary line to split the image to a plurality of parts;
determining whether an object is included in the image;
splitting the image to a first part of the image and a second part of the image according to the split boundary line;
recognizing whether at least part of the object is missed from the first part of the image or from the second part of the image;
in response to recognizing that at least part of the object is missed from the first part of the image adding the at least part of the object to the first part of the image;
displaying the first part of the image or the second part of the image; and
transmitting a remaining part of the image which is not displayed to a second display device such that the remaining part of the image is displayed on the second display device,
wherein the first part of the image entirely includes the object and the second part of the image includes the at least part of the object.
2. The method of claim 1 , wherein the splitting of the image to the first part of the image and the second part of the image comprises determining an offset between the first part of the image and the second part of the image, and
wherein the offset is a difference between a display end point of the first part of the image and a display start point of the second part of the image.
3. The method of claim 1 , wherein the determining of whether the object is included in the image comprises determining whether a character or a person's face is included in the image.
4. The method of claim 3 , wherein an overall shape of the character or an overall shape of the person's face is included in the first part of the image.
5. The method of claim 1 , wherein the second part of the image is displayed on a screen of the second display device while the first display device displays the first part of the image.
6. A first display device, comprising:
a display unit;
a transceiver; and
a processor configured to:
acquire an image and a split boundary line to split the image to a plurality of parts,
determine whether an object is included in the image,
split the image to a first part of the image and a second part of the image according to the split boundary line,
recognize whether at least part of the object is missed from the first part of the image or from the second part of the image,
in response to recognizing that at least part of the object is missed from the first part of the image, add the at least part of the object to the first part of the image,
control the display unit to display the first part of the image or the second part of the image, and
control the transceiver to transmit a remaining part of the image which is not displayed to a second display device, such that the remaining part of the image is displayed on the second display device,
wherein the first part of the image entirely includes the object and the second part of the image includes the at least part of the object.
7. The first display device of claim 6 ,
wherein the processor is further configured to determine an offset between the first part of the image and the second part of the image, and
wherein the offset is a difference between a display end point of the first part of the image and a display start point of the second part of the image.
8. The first display device of claim 6 , wherein the processor is further configured to determine whether a character or a person's face is included in the image.
9. The first display device of claim 8 , wherein an overall shape of the character or an overall shape of the person's face is included in the first part of the image.
10. The first display device of claim 6 , wherein the second part of the image is displayed on a display unit of the second display device while the display unit displays the first part of the image.
