Abstract

According to an embodiment, a processor of an electronic device identifies a combination of a first projection area for the electronic device and a second projection area for an external electronic device. The processor displays a portion of a visual object for guiding a reference aspect ratio in the first projection area. The portion is segmented from the visual object based on a location of the first projection area in the combination. The processor adjusts the portion, based on the motion of the electronic device. The processor displays, based on identification of an aspect ratio of the combination being corresponded to the reference aspect ratio, at least portion of media content having the reference aspect ratio in the first projection area.

First claim

What is claimed is:

1. An electronic device comprising:
a sensor;
communication circuitry;
a projection assembly;
memory comprising one or more storage media storing instructions; and
at least one processor,
wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify, based on an identification of an external electronic device through the communication circuitry, a combination of a first projection area where light of the projection assembly is projected and a second projection area where light of the external electronic device is projected;
display a first portion of a visual object for guiding a reference aspect ratio in the first projection area, wherein the first portion is segmented from the visual object based on a location of the first projection area in the combination of the first projection area and the second projection area, wherein the visual object comprises the first portion and a second portion;
identify a motion of the electronic device based on data of the sensor;
based on the motion of the electronic device identified while displaying the first portion of the visual object, display the second portion of the visual object that is segmented from the visual object based on the location of the first projection area in the combination of the first projection area and the second projection area, that is changed according to the motion; and
based on identifying an aspect ratio of the combination of the first projection area and the second projection area corresponding to the reference aspect ratio, display at least a portion of media content having the reference aspect ratio in the first projection area.

2. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to, in a state displaying the first portion of the visual object, transmit, to the external electronic device through the communication circuitry, a signal for displaying a third portion of the visual object such that the visual object having the reference aspect ratio is visible within the combination of the first projection area and the second projection area.

3. The electronic device of claim 1 , wherein the visual object is a rectangle having a width or a height of the combination of the first projection area and the second projection area,
wherein the aspect ratio of the visual object corresponds to the reference aspect ratio, and
wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to adjust the width or the height of the first portion of the visual object in the first projection area.

4. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify, in an image received through the communication circuitry, the second projection area at least partially overlapping the first projection area, and
based on the identified second projection area, display the first portion of the visual object.

5. The electronic device of claim 4 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to receive, from another external electronic device different from the external electronic device through the communication circuitry, the image.

6. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify the combination of the first projection area and the second projection area being larger than the first projection area, and
based on the location of the first projection area in the identified combination of the first projection area and the second projection area, selectively display the first portion of the visual object.

7. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to, based on an input to form a projection area larger than the first projection area, initiate identifying the external electronic device by using the communication circuitry.

8. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to adjust a first brightness of a first overlapping portion in the first projection area to which is overlapped to the second projection area, to a second brightness,
wherein the first brightness is different from the second brightness of a second overlapping portion of the first projection area, and
wherein the second overlapping portion is distinct from the first overlapping portion.

9. A method of an electronic device including a sensor, a projection assembly and communication circuitry, the method comprising:
identifying, based on an identification of an external electronic device through the communication circuitry, a combination of a first projection area where light of the projection assembly is projected and a second projection area where light of the external electronic device is projected;
displaying a first portion of a visual object for guiding a reference aspect ratio in the first projection area, wherein the first portion of the visual object corresponds to a location of the first projection area in the combination of the first projection area and the second projection area, wherein the visual object comprises the first portion and a second portion;
identifying a motion of the electronic device based on data of the sensor;
based on the motion of the electronic device identified while displaying the first portion of the visual object, displaying the second portion of the visual object that is segmented from the visual object based on the location of the first projection area in the combination of the first projection area and the second projection area, that is changed according to the motion; and
based on identifying an aspect ratio of the combination of the first projection area and the second projection area corresponding to the reference aspect ratio, displaying at least a portion of media content having the reference aspect ratio in the first projection area.

10. The method of claim 9 , wherein the displaying the first portion of the visual object comprises transmitting, to the external electronic device through the communication circuitry, a signal for displaying a third portion of the visual object such that the visual object having the reference aspect ratio is visible within the combination of the first projection area and the second projection area.

11. The method of claim 9 , wherein the visual object is a rectangle having a width or a height of the combination of the first projection area and the second projection area,
wherein the visual object has the reference aspect ratio, and
wherein the displaying of the first portion of the visual object comprises adjusting the width or the height of the first portion of the visual object through the first projection area.

12. The method of claim 9 , further comprising identifying the second projection area at least partially overlapping the first projection area in an image received through the communication circuitry,
wherein the displaying of the first portion of the visual object comprises displaying, based on the identified second projection, the second portion of the visual object.
