The control unit 140 controls each electronic device to perform photographing simultaneously in the camera module of the first electronic device # 1, the camera module of the second electronic device # 2 and the camera module of the third electronic device # A control signal can be transmitted.

For example, the touch input corresponding to the batch photographing can be detected by touching the collective photographing button as shown in the upper right of FIG. 4 (a). Alternatively, the touch input corresponding to the batch shooting can be detected by multi-touching all the preview screens 10, 20, and 30 displayed on the touch screen 130 at once.

According to the batch photographing, photographing is performed in the camera module of each electronic device, and when the photographing is completed, the first electronic device (# 1) can receive the photographed image in each electronic device.

For example, the first electronic device # 1 may display images photographed at each electronic device at once or sequentially on the touch screen 130, or may store the images in the storage unit 150. [

As another example, the first electronic device # 1 may display the images photographed in each electronic device on the touch screen 130 in a collage form according to the user's selection, or may store them in the storage unit 150. [ In this case, the first electronic device # 1 may provide the editing function of the photographed image in each electronic device.
