<P>PROBLEM TO BE SOLVED: To exchange a large capacity of information between a plurality of information memory devices at high speed with low power consumption. <P>SOLUTION: When one of digital cameras C-01, C-02, C-03 and C-04 is used to photograph an image, index information about acquired image data (original image data) is transmitted to the other digital camera via wide-band low-speed communication. A display 208 of each digital camera also displays index images for images photographed by the other digital camera, whereby the user can select desired one of the images. When two of the digital cameras are connected to each other via narrow-band high-speed communication, the original image data indicative of the index image selected by the user is transmitted from one digital camera to the other digital camera via the narrow-band high-speed communication. <P>COPYRIGHT: (C)2010,JPO&INPIT |
