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.
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.
1.1.1High 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] characterisitcs, 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 sensing conditions. It is possible to select continuous shutter, random shutter, or
optional time shutter.

2.3.5Outline Emphasis Circuit ON/OFF Switch SW2
Switch SW2 controls the outline emphasis circuit on the MC-780PIH. Do not
move this switch on the MC-780PIA. The outline emphasis circuit makes the
image easier to see by emphasizing the image outline when the camera is
used for surveillance. T able 2–12 lists the switch positions and functions, and
Figure 2–10 shows the switch.
The camera can be synchronized externally by inputting an external sync signal. 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.
On the rear panel, set switch 5 of mode switch SW3 to ON.

Using the Shutter Modes
This chapter describes the various shutter modes and how to use them.
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.
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.
The random shutter operates only when the shutter command has been
added, so continuous shutter is the normal operating mode.
Figure 4–2 shows the random shutter speed control timing with fixed V sync.

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, exposure will occur for the period of the command. This mode is only for non-interlace. The image quality may be lower due to timed exposures; use accordingly .

Precautionary Items
4.5Precautionary 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 follows. 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. T able 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.

1/5002219
1/7501311
1/100063
1/1500
-
Due to the circumstances noted above, during random shutter, when there
is no shutter trigger input, the camera will be in continuous shutter mode.
Consequently the 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 appears to flicker because the positions shown on the monitor differ.
-
When a timed exposure is made of over 1/60 second operating in VI mode,
impurities on the CCD may become exaggerated. Also, due to the occurrence 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.

Chapter 5
Initial Settings
This chapter describes the modes of operation and the initial switch settings.
With this unit it is possible to switch the operating modes to suit the intended
use. All mode settings can be set with switches. Table 5–1 summarizes the
modes and initial switch settings.
The camera operates on +12 V. Use a stable ripple- and noise-free power
source.
6.1.2Heat 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.
6.1.3Locations 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 moisture-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

Precautions for Use
6.2Maintenance
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.
