Camera system operable in accordance with stored memory
First Claim
1. In a camera system operable in accordance with memory data by means of carrying the memory data from a camera accessory to a camera body, the improvement comprising:
- first means for carrying electric power from the camera body to the camera accessory to power the camera accessory;
second means for carrying a train of clock pulses from the camera body to the camera accessory to synchronize the camera accessory with the camera body;
third means for serially carrying address data from the camera body to the camera accessory to locate the memory data;
fourth means for serially carrying the memory data corresponding to the address data from the camera accessory to the camera body; and
fifth means for carrying an initiating signal from the camera body to the camera accessory to control the timing of reading the memory data corresponding to the address data.

Abstract
A camera system is provided that permits memory data dedicated to particular camera accessories to be transmitted to the camera body for enabling the operation of the camera. The camera accessories can carry dedicated information or variable information to the camera body. Synchronization between the camera accessory and the camera body can be provided by a train of clock pulses. Information can be programmed in a fixed memory circuit to insure that only a particular accessory so designated will provide information to the camera body to prevent any erroneous inputting of data from a plurality of camera accessories that are contemplated for use with a particular camera body.
