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.

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 shutter speed outputs black

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

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.
