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.

1.1.1High Image Quality

With 380,000 image-sensing elements, the CCDs reproduce very detailed images.

1.1.2Mode Settings

Several modes can be selected depending on the intended use. For example, using external switches for gain, it is possible to select A (auto adjust), F (fixed), or M (manual adjust); using the internal switches for γ [gamma] charac- terisitcs, it is possible to select ON (corrected: γ = 0.45) and OFF (uncorrected:

γ= 1).

1.1.3External Sync

The camera module can be operated with external sync by inputting HD and VD signals. Internal or external sync can be selected with the mode switches.

1.1.4Output of Internal Synchronizing Signals

HD and VD signals can be output by switching their internal switches. Pixel clock signals and shutter monitor signals can also be selected and output.

1.1.5Electronic Shutter

A shutter speed can be selected from 1/500 to 1/8000 second to match sens- ing conditions. It is possible to select continuous shutter, random shutter, or optional time shutter.
