Abstract
A modular CCD includes a camera head and a camera body. The camera body includes an amplifier, an A/D converter, a D/A converter, a video simulator, a summation circuit and a switch. The switch is used to controllably switch between the output of the camera head and the video simulator output. A system is provided for adjusting the voltage supplied to the switch by the D/A converter to adjust the voltage output of the summation circuit to compensate for the difference between those outputs so that the camera body can accept different camera heads with different gain requirements.
