A method for compositing images in a portable terminal, the method comprising: acquiring a plurality of images; displaying the plurality of images on a display unit; determining a composition region of each of the plurality of images; compositing the plurality of images by using the composition regions of the plurality of images; and displaying a composed image on the basis of the composition regions on the display unit; characterised in that: the portable terminal comprises two cameras, a first camera, equipped at a first side of the portable terminal, and a second camera, equipped at a second side opposite to the first side of the portable terminal; the acquiring the plurality of images comprises acquiring in real time a first image via the first camera and a second image via the second camera; the determining the composition region of each of the plurality of images comprises: determining a plurality of candidate first composition regions in the first image and a plurality of candidate second composition regions in the second image; displaying the plurality of candidate first and second composition regions on the display unit; identifying a user input for selecting one of the candidate first composition regions and one of the second composition regions; and the compositing comprises compositing, in response to the identifying of the user input, a portion of the first image and a portion of the second image based on the selected candidate first composition region and the selected candidate second composition region. acquiring a plurality of images; displaying the plurality of images on a display unit; determining a composition region of each of the plurality of images; compositing the plurality of images by using the composition regions of the plurality of images; and displaying a composed image on the basis of the composition regions on the display unit; characterised in that: the portable terminal comprises two cameras, a first camera, equipped at a first side of the portable terminal, and a second camera, equipped at a second side opposite to the first side of the portable terminal; the acquiring the plurality of images comprises acquiring in real time a first image via the first camera and a second image via the second camera; the determining the composition region of each of the plurality of images comprises: determining a plurality of candidate first composition regions in the first image and a plurality of candidate second composition regions in the second image; displaying the plurality of candidate first and second composition regions on the display unit; identifying a user input for selecting one of the candidate first composition regions and one of the second composition regions; and determining a plurality of candidate first composition regions in the first image and a plurality of candidate second composition regions in the second image; displaying the plurality of candidate first and second composition regions on the display unit; identifying a user input for selecting one of the candidate first composition regions and one of the second composition regions; and the compositing comprises compositing, in response to the identifying of the user input, a portion of the first image and a portion of the second image based on the selected candidate first composition region and the selected candidate second composition region.
