1-1 Overview Overview This User ’s Guide describes the operation and characteristics of the MC-780PIA and MC780PIH video cameras. This chapter gives an overview of the cameras and their features. Please read and keep this document as a reference. T opic Page 1.
Main Features 1-2 Overview 1.1 Main Features The MC-780PIA and MC-780PIH are black-and-white video cameras that use fixed-sensor charge-coupled devices (CCDs). The following paragraphs de- scribe some of the main features of the cameras. 1.1.1 High Image Quality With 380,000 image-sensing elements, the CCDs reproduce very detailed images.
Other Features 1-3 Overview 1.2 Other Features Long life span, high reliability Low distortion, high precision image High near infrared sensitivity Quick starting.

DC IN/SYNC T erminal 2-6 Nomenclature and Use of Each Component The odd fields are low and the even fields are high for the pin 1 field index output. The pin 5 image signal is provided for auto-iris use so it cannot be con- nected to a monitor . The dc voltage output from pin 6 is the same as the input voltage.
Internal Switches 2-7 Nomenclature and Use of Each Component 2.3 Internal Switches Remove the camera cover to set the internal switches. Viewing the camera from the front, the switches are located on boards in the center and the left. The center board is called the clock board, and the left board is called the pro- cess board.

Continuous Shutter 4-2 Using the Shutter Modes 4.1 Continuous Shutter On the rear panel mode switch SW3, set switch 1 to ON and switch 2 to OFF . Use the shutter speed control switch SW1 to set the shutter speed. Figure 4–1 shows the continuous shutter speed control timing.
Random Shutter (Fixed V Sync) 4-3 Using the Shutter Modes 4.2 Random Shutter (Fixed V Sync) On the rear panel mode switch SW3, set switch 1 to ON and switch 2 to OFF .
Random Shutter (V Sync Reset) 4-4 Using the Shutter Modes 4.3 Random Shutter (V Sync Reset) On the rear panel mode switch SW3, set switch 1 to OFF and switch 2 to ON. Use the shutter speed control switch SW1 to set the shutter speed. Figure 4–3 shows the random shutter speed control timing with V sync reset.
VI Mode Shutter 4-5 Using the Shutter Modes 4.4 VI Mode Shutter On the rear panel mode switch SW3, set switches 1 and 2 to ON. At this point there will be no image output. When an external VI command is input, expo- sure will occur for the period of the command.
Precautionary Items 4-6 Using the Shutter Modes 4.5 Precautionary Items Observe the following precautions when operating the electronic shutter . The CCD for this camera uses the frame transfer method. At shutter speeds of 1/500, 1/1000, and 1/1500 second, the exposure period and the transfer period conflict with the readout period.
