A method of an electronic apparatus for providing a panorama image, the method comprising: acquiring photograph exposure values of first images that are photographed respectively through a first and a second camera (110; 110-1, 110-2); determining whether a difference between the photograph exposure values acquired respectively from the first and the second camera (110; 110-1, 110-2) is outside a preset threshold range; characterized in that the method further comprises: when the difference between the acquired photograph exposure values is determined to be within the preset threshold range, generating a panorama image comprising the first images that are photographed respectively through the first and second camera (110; 110-1, 110-2); the method further comprising displaying an icon for a reference camera setting; based on a selection of the displayed icon for the reference camera setting, displaying a list comprising objects respectively corresponding to the first and second cameras (110; 110-1, 110-2), while displaying the icon for the reference camera setting; and when the difference between the acquired photograph exposure values is determined to be outside the preset threshold range: based on a selection of one of the objects included in the displayed list, resetting the photograph exposure value to be applied to another camera among the first and second camera (110; 110-1, 110-2), by a photograph exposure value of a reference camera corresponding to the selected one of the objects among the first and second camera; and generating a panorama image comprising second images that are photographed respectively through the plurality of cameras (110; 110-1, 110-2) using the reset photograph exposure value. acquiring photograph exposure values of first images that are photographed respectively through a first and a second camera (110; 110-1, 110-2); determining whether a difference between the photograph exposure values acquired respectively from the first and the second camera (110; 110-1, 110-2) is outside a preset threshold range; characterized in that the method further comprises: when the difference between the acquired photograph exposure values is determined to be within the preset threshold range, generating a panorama image comprising the first images that are photographed respectively through the first and second camera (110; 110-1, 110-2); the method further comprising displaying an icon for a reference camera setting; based on a selection of the displayed icon for the reference camera setting, displaying a list comprising objects respectively corresponding to the first and second cameras (110; 110-1, 110-2), while displaying the icon for the reference camera setting; and when the difference between the acquired photograph exposure values is determined to be outside the preset threshold range: based on a selection of one of the objects included in the displayed list, resetting the photograph exposure value to be applied to another camera among the first and second camera (110; 110-1, 110-2), by a photograph exposure value of a reference camera corresponding to the selected one of the objects among the first and second camera; and generating a panorama image comprising second images that are photographed respectively through the plurality of cameras (110; 110-1, 110-2) using the reset photograph exposure value. when the difference between the acquired photograph exposure values is determined to be within the preset threshold range, generating a panorama image comprising the first images that are photographed respectively through the first and second camera (110; 110-1, 110-2); the method further comprising displaying an icon for a reference camera setting; based on a selection of the displayed icon for the reference camera setting, displaying a list comprising objects respectively corresponding to the first and second cameras (110; 110-1, 110-2), while displaying the icon for the reference camera setting; and when the difference between the acquired photograph exposure values is determined to be outside the preset threshold range: based on a selection of one of the objects included in the displayed list, resetting the photograph exposure value to be applied to another camera among the first and second camera (110; 110-1, 110-2), by a photograph exposure value of a reference camera corresponding to the selected one of the objects among the first and second camera; and generating a panorama image comprising second images that are photographed respectively through the plurality of cameras (110; 110-1, 110-2) using the reset photograph exposure value. based on a selection of one of the objects included in the displayed list, resetting the photograph exposure value to be applied to another camera among the first and second camera (110; 110-1, 110-2), by a photograph exposure value of a reference camera corresponding to the selected one of the objects among the first and second camera; and generating a panorama image comprising second images that are photographed respectively through the plurality of cameras (110; 110-1, 110-2) using the reset photograph exposure value.
