Abstract
A modular camera system includes a basic camera having an image forming optical system, image focal plane arrangement, and predetermined imaging and camera functions. The modular camera system further includes modules that are selectively attachable and connectable to the basic camera for providing additional camera and imaging functions and controls. The module includes appropriate module control circuitry for controlling the operation of the basic camera concerning predetermined camera and imaging functions when the module is attached to the basic camera to form the modular camera system.
