摘要

For providing a communication system capable of easily and efficiently confirming information present in another device and easily and efficiently selecting desired information from such information, a digital camera informs a printer of format information of an image file (including a photographed image, a thumbnail image formed by reducing the photographed image) held in an internal memory of the digital camera, so that the printer can directly fetch the thumbnail image only from the image file held in the internal memory of the digital camera, for example by the pull-type data transfer method.
