PASSIVE TRANSCEIVER FOR ELECTRONIC STILL CAMERAS

摘要

Electronic imaging system for bi-directional communication is disclosed wherein a base unit communicates with at least one electronic still camera using a passive transmission scheme. The base unit transmits a carrier signal encoded with base information to an electronic still camera. The electronic still camera then decodes that information and responds appropriately. When an image is captured by the electronic still camera, the image signal is modulated into the carrier signal then retransmitted from the camera to the base unit where the image can be decoded and stored.
