Digital cameras which improve operability in checking, storing, and editing shot images have not been satisfactory. A digital camera and a user terminal including a file server are connected over a network. When the digital camera is powered on, it automatically establishes a network connection with the file server in an activation process. When the digital camera shoots an image, this image is transmitted to the file server automatically upon completion of the encoding and compression of the image. When image reproduction is instructed from the digital camera, the image is downloaded from the file sever over the network and displayed on the digital camera.
