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 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.  
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] charac-  
terisitcs, 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 sens-  
ing conditions. It is possible to select continuous shutter, random shutter, or  
optional time shutter.

Mounting System  
2.1 Mounting System  
The following paragraphs describe the mounting system for the camera  
modules.  
2.1.1 Focus Ring  
C-Mount type lens and optical equipment are installed. If there is difficulty fo-  
cusing with the lens, fine adjustments can be made by loosening the two  
screws located on the ring. The lens can also be brought back closer to the  
CCD by removing the focus ring.  
2.1.2 Mounting Holes A  
There are four screw holes on the top and bottom for mounting the camera  
module. The gauge is M2.6 and the depth is 4.5 mm.  
2.1.3 Mounting Hole B  
There is a screw hole on the bottom for mounting the camera module. The  
gauge is M4 and the depth is 6 mm.  
2.1.4 Mounting Holes C  
There are screw holes on the bottom for mounting the camera module to a  
tripod. The gauge is 1/4UNC and the depth is 6 mm.

The odd fields are low and the even fields are high for the pin 1 field index

The dc voltage output from pin 6 is the same as the input voltage.  
2.2.8 DC IN/SYNC Terminal  
This terminal supplies the +12 V power, outputs the image from the camera  
module, and inputs/outputs sync signals, through cable connector

Using the External SYNC Mode  
The camera can be synchronized externally by inputting an external sync sig-  
nal. When using external sync, set the clock board’s sync signal input/output  
switch (SW1) to the external sync signal in (upper switch position) and  
switches 3 and 4 to the mode switch (SW3), located on the rear panel, to ON.

Precautionary Items  
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. There is black output from  
the line count, which conforms to the shutter speed; the image output fol-  
lows. Thus the lower part of the image output cannot be output onto the  
screen to the degree of the line count of the black output. Figure 4–5  
shows what occurs. Table 4–1 lists the line counts for each shutter speed.  
Figure 4–5. Exposure and Transfer Period Conflict With Readout Period  
The line count conforming to  
the shutter speed outputs black  
Screen  
The lower part of the image  
cannot output to the extent of  
the line count conforming to the  
shutter speed.

Duetothecircumstancesnotedabove, duringrandomshutter, whenthere  
is no shutter trigger input, the camera will be in continuous shutter mode.  
Consequentlythe bottom part of the image is not shown for shutter speeds  
of 1/500 through 1/1500 second. Images shot with random shutter have  
a full image output without the bottom part eliminated. Thus the image ap-  
pears to flicker because the positions shown on the monitor differ.  
Whenatimedexposureismadeofover1/60secondoperatinginVImode,  
impurities on the CCD may become exaggerated. Also, due to the occur-  
rence of dark current, the image may be rough. The image quality of timed  
exposures is uncertain.  
Use non-interlace scanning when in random shutter and VI modes.

Precautions for Use  
6.1 Precautions for Use  
6.1.1 Power Source  
The camera operates on +12 V. Use a stable ripple- and noise-free power  
source.  
6.1.2 Heat Reduction  
To keep the temperature inside the camera from rising in some situations  
(such as when operating the camera inside a tightly sealed case) it may be  
necessary to use forced air conditioning.  
6.1.3 Locations for Use and Storage  
Do not operate or store the camera in the following locations:  
Locations of extreme heat or cold. The proper temperature for use is 0°C  
to 40°C.  
Locations with considerable moisture or dust  
Locations in direct contact with rain (the camera is not waterproof or mois-  
ture-proof)  
Locations with corrosive gas  
Locations with flammable gas (it is not explosion-proof)  
Locations with severe vibration  
Near radios or television transmitters, which generate strong electrical  
waves  
6-2  
Precautions for Use  
 
Maintenance  
6.2 Maintenance  
Use a blower to remove dirt or dust adhering to the CCD glass cover. Wiping  
the glass forcefully can damage the glass or create static electricity that can  
damage the CCD.  
Use a soft, dry cloth to clean dirt off the exterior. If it is extremely dirty, use a  
small amount of a neutral detergent on a cloth to remove it, and then wipe with  
a dry cloth. Do not use alcohol or benzene, as they may discolor the surface  
and cause peeling.
