Main Features
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 describe 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.
1.1.2 Mode 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] characterisitcs, it is possible to select ON (corrected: γ = 0.45) and OFF (uncorrected:
γ = 1).
1.1.3 External 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.
1.1.4 Output 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.
1.1.5 Electronic Shutter
A shutter speed can be selected from 1/500 to 1/8000 second to match sensing conditions. It is possible to select continuous shutter, random shutter, or
optional time shutter.
