Abstract
Abstract A camera system being comprised of a camera and an external device is disclosed. The external device is detachably mounted on the camera which memorizes a program or data necessary for executing a program therein. When the external device is mounted on the camera, they are connected electrically with each other and communicate therebetween in order to read a program or data memorized in the external device into a memory means provided in the camera. The camera is controlled according to the program designated by the external device.
