Combining effective images in electronic device having a plurality of cameras

An electronic device having a plurality of cameras for combining effective images, the electronic device comprising:

• a first camera which successively photographs images in response to a photographing signal;
• a second camera which photographs a second image;
• and
• a controller which selects a first image satisfying a predetermined classification reference from the images successively photographed through the first camera and combines the first and second images.

A method of combining effective images in an electronic device having front and rear cameras, the method comprising:

• in response to a photographing signal, capturing front and rear images from the front and rear cameras, respectively;
• determining a difference in at least one of brightness and tone between the front and rear images;
• modifying at least one of the front and rear images to equalize brightness or tone between the front and rear images if the difference exceeds a predetermined threshold;
• and
• combining the front and rear images.
