An image pickup device includes a main body, in which a processing unit is provided to electrically connect to a front image pickup unit mounted on a front side of the main body, an image display unit mounted to one side of the main body, a rear image pickup unit mounted on a rear side of the main body, and a memory unit and a power supply unit mounted in the main body. The processing unit has an image combination processing module for combining images picked up by the front and the rear image pickup unit into one image. With this design, images in front of and behind the image pickup device can be simultaneously captured and then combined into one to provide a photographer with more flexibility and fun in using the image pickup device.
