Mobile terminal having two cameras and method for storing images taken by two cameras

Abstract

A mobile terminal includes a memory; a touch screen; a first camera having a first capturing angle; a second camera having a second capturing angle that is wider than the first capturing angle; and a controller. The controller is configured to: cause the touch screen to display a first preview image of the first camera, a second preview image of the second camera, or both the first and second preview images overlapping each other; cause the memory to store a first image taken by the first camera in response to a first capture command received while the first preview image is displayed; and cause the memory to store both the first image and a second image taken by the second camera when a wide-angle capturing condition is satisfied while at least one of the first preview image or the second preview image is displayed.

 measure a distance between the mobile terminal and a subject to be captured via the first or second camera; and 
 in response to a capture command:
 capture both a first image taken by the first camera and a second image taken by the second camera when the measured distance is satisfied for a specific distance condition; and

 capturing the first image only when the measured distance is not satisfied for the specific distance condition. 
 
 
     
     
       8. The method of  claim 7 , wherein the specific distance condition is satisfied when the measured distance is greater than a prescribed distance. 
     
     
       9. The method of  claim 8 , further comprising:
 displaying, on the touch screen, an image synthesized from the captured first image and second image.

 displaying, on the the touch screen, a graphic element to adjust a ratio of the first image to the second image for the synthesized image. 
 
     
     
       11. The method of  claim 9 , wherein the synthesized image is generated by overlapping at least a portion of the second image such that an object in the first image coincides with the same object in the second image. 
     
     
       12. The method of  claim 9 , further comprising:
 displaying, on the touch screen, a preview image synthesized from the first preview image and the second preview image before the first image and the second image are captured when the measured distance is satisfied for the specific distance condition.
