Abstract

A method and an apparatus for dual recording shooting in an electronic device including a dual camera are provided. The method includes acquiring a first picture from a first camera that is in an operation state, acquiring a second picture from a second camera that is in a wait state, outputting the first picture at a first resolution, downscaling the second picture to a second resolution, outputting the second picture downscaled to the second resolution, and synthesizing the first picture and the second picture that is downscaled to the second resolution and previewing the synthesized result, using a Picture In Picture (PIP) function and, when a dual recording start instruction event occurs, restoring the second picture that is downscaled to the second resolution to a previous resolution, outputting the second picture restored to the previous resolution, synthesizing the first picture and the restored second picture, and recording the synthesized result.

First claim

What is claimed is:

1. A method in an electronic device, the method comprising the operations of:
acquiring a first picture from a first camera that is in an operation state;
acquiring a second picture from a second camera that is in a wait state;
outputting the first picture at a first resolution;
downscaling the second picture to a second resolution;
outputting the second picture downscaled to the second resolution;
synthesizing the first picture and the second picture that is downscaled to the second resolution and previewing the synthesized result using a Picture In Picture (PIP) function;
when a dual recording start instruction event occurs, restoring the second picture that is downscaled to the second resolution to a previous resolution;
outputting the second picture restored to the previous resolution; and
synthesizing the first picture and the restored second picture, and recording the synthesized result,
wherein the first resolution is higher than the second resolution.

2. The method of claim 1 , wherein the second resolution of the second picture is a resolution lower than the previous resolution of the second camera, and
wherein a current consumption is greater when the second picture is output at the previous resolution than when the second picture is output at the second resolution.

3. The method of claim 1 , wherein the second resolution of the second picture is a resolution lower than the previous resolution of the second camera, and
wherein the second resolution is set to a minimum pixel supported by an image sensor of the second camera.

4. The method of claim 1 , wherein the second resolution of the second picture is a resolution lower than the previous resolution of the second camera, and
wherein the second resolution is a resolution corresponding to a minimum pixel capable of detecting a mouse shape of a subject.

5. The method of claim 1 , further comprising, while synthesizing the first picture and the restored second picture and recording the synthesized result, upon occurrence of a dual recording stop instruction event, outputting the first picture at the first resolution, downscaling the restored second picture to the second resolution, outputting the second picture that is downscaled to the second resolution, and synthesizing the first picture and the second picture that is downscaled to the second resolution and previewing the synthesized result, using the PIP function.

6. The method of claim 5 , wherein the dual recording stop instruction event occurs when a mouse shape is not detected from a subject of the second picture, or occurs when an object corresponding to a dual recording stop instruction is selected.

7. The method of claim 5 , wherein the dual recording stop instruction event occurs when a user inputs a dual recording stop instruction to the electronic device.

8. The method of claim 1 , wherein the dual recording start instruction event occurs when a mouse shape is detected from a subject of the second picture, or occurs when an object corresponding to a dual recording start instruction is selected.

9. An electronic device comprising:
a first camera for taking pictures;
a second camera for taking pictures;
at least one processor for executing computer programs;
at least one memory for storing data and instructions; and
at least one program stored in the memory, and constructed to be executable by the at least one processor,
wherein the program comprises an instruction of:
acquiring a first picture from the first camera that is in an operation state;
acquiring a second picture from the second camera that is in a wait state;
outputting the first picture at a first resolution;
downscaling the second picture to a second resolution;
outputting the second picture downscaled to the second resolution;
synthesizing the first picture and the second picture that is downscaled to the second resolution and previewing the synthesized result, using a Picture In Picture (PIP) function; and
when a dual recording start instruction event occurs, restoring the second picture that is downscaled to the second resolution to a previous resolution;
outputting the second picture restored to the previous resolution;
synthesizing the first picture and the restored second picture, and recording the synthesized result,
wherein the first resolution is higher than the second resolution.

10. The electronic device of claim 9 , wherein the second resolution of the second picture is a resolution lower than the previous resolution of the second camera, and
wherein a current consumption is greater when the second picture is output at the previous resolution than when the second picture is output at the second resolution.

11. The electronic device of claim 9 , wherein the second resolution of the second picture is a resolution lower than the previous resolution of the second camera, and
wherein the second resolution is set to a minimum pixel supported by an image sensor of the second camera.

12. The electronic device of claim 9 , wherein the second resolution of the second picture is a resolution lower than the previous resolution of the second camera, and
wherein the second resolution is a resolution corresponding to a minimum pixel capable of detecting a mouse shape of a subject.

13. The electronic device of claim 9 , wherein, while synthesizing the first picture and the restored second picture and recording the synthesized result, upon occurrence of a dual recording stop instruction event, the program further comprises an instruction of outputting the first picture at the first resolution, downscaling the restored second picture to the second resolution, outputting the second picture that is downscaled to the second resolution, and synthesizing the first picture and the second picture that is downscaled to the second resolution and previewing the synthesized result, using the PIP function.

14. The electronic device of claim 13 , wherein the dual recording stop instruction event occurs when a mouse shape is not detected from a subject of the second picture, or occurs when an object corresponding to a dual recording stop instruction is selected.

15. The electronic device of claim 9 , wherein the dual recording start instruction event occurs when a mouse shape is detected from a subject of the second picture, or occurs when an object corresponding to a dual recording start instruction is selected.

16. The electronic device of claim 9 , wherein a dual recording stop instruction event occurs when a user inputs a dual recording stop instruction to the electronic device.

17. A method in an electronic device, the method comprising the operations of:
detecting if a dual recording shooting instruction event occurs;
when the dual recording shooting instruction event does not occur, outputting a first picture from a first camera at a first resolution, downscaling a second picture to a second resolution, and outputting the second picture downscaled to the second resolution from a second camera;
synthesizing the first picture and the second picture that is downscaled to the second resolution and previewing the synthesized result, using a Picture In Picture (PIP) function;
when the dual recording start instruction event occurs, outputting a first picture from the first camera at a first resolution, restoring the second picture that is downscaled to the second resolution to a previous resolution, and outputting the second picture restored to the previous resolution; and
synthesizing the first picture and the restored second picture and recordi
