Method for dual recording shooting and electronic device thereof

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.

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 the 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 recording the synthesized result,
• wherein the first resolution is higher than the second resolution.
