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.

Using the External SYNC Mode
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.

4.2 Random Shutter (Fixed V Sync)
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.

This mode is only for non-inter­lace. The image quality may be lower due to timed exposures; use accordingly . Figure 4–4 shows the VI mode shutter timing.

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 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 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.
Table 4–1.Line Table Corresponding to Shutter Speeds
Shutter Speed MC-7890PIA MC-780PIH
1/500 22 19 1/750 13 11 1/1000 6 3 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.

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 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
6.2 Maintenance
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.
