To hold a virtual photographing party using a photographing system 1 and a digital camera 10.

When a virtual photograph mode is set in a digital camera 10, the digital camera 10 detects photographing conditions, e.g. photographing direction and magnification, and delivers that data to a server 30. Three- dimensional data concerning to a virtual object is stored at a three-dimensional data storing section 40 and the server 30 generates a two-dimensional image from the three-dimensional data depending on the photographing conditions inputted from the digital camera 10. When the photographing direction, or the like, of the digital camera 10 is altered, a new two-dimensional image is generated depending on the alteration. An image generated from the server 30 is delivered to the digital camera 10 and displayed. Framing, or the like, of the virtual object can thereby be performed in the digital camera 10.
