Abstract
A camera system including a camera and a data back has recording, display, and control functions. Signals are exchanged between CPU's of the camera and the data back through interface circuits. In one embodiment, the data back delivers periodic shutter release commands to the camera in an interval mode of operation so that the shutter is released cyclically. A shutter release signal causes an exposure operation, the completion of which terminates the shutter release signal. Then the shutter release signal is generated again to cause another exposure operation. If shutter release is not completed within a predetermined period, a new cycle of shutter release operation is nevertheless initiated.
