Ccd Properties - Hitachi HV-D25 Operation Manual

Lens
The correct lens is important for deriving optimum performance from the camera. Consult a Hitachi
Denshi dealer for a selection of fine lenses according to the application.
Installation and storage sites
The following types of environment can impair performance, lead to damage, pose safety hazards and
shorten the useful life of the camera. Select the sites for installing the storing the camera carefully.
• Direct sunlight, rain or snow
• Flammable or corrosive gasses
• Very hot or cold (beyond -10 to 45
• Humid or dusty
• Exposed to vibration or shock
• Strong electrical or magnetic fields
• Exceptionally strong light
Continuous operation Continuous operation Continuous operation Continuous operation
In situations where the camera is used continuously for long periods of time, the ambient temperature
should be kept below 40
maximum long-term reliability.
Cleaning Cleaning
Cleaning Cleaning
A photographers blower or lens brush can be used for clearing dust from the lens and optical filters.
Wipe dust from the case with a soft dry cloth. If soiling is severe, moisten the cloth with a solution of
neutral detergent. Afterwards, wipe the cover with a dry cloth.
Do not use petroleum distillates, alcohol or spray type cleaners.
Transportation Transportation Transportation Transportation
Remove the lens (install lens mount cap) and other attachments. Pack the camera carefully in its original
or equivalent container. Use ample cushioning to protect the camera from physical shock.

CCD properties

The following phenomena are inherent to a charge coupled device imaging element and do not indicate
malfunction.
1) Smear and blooming
Vertical bands are visible when a strong light enters the scene. Adjust the camera aiming direction
carefully to avoid strong direct or reflected light.
2) Fixed pattern noise
High ambient temperature can cause fixed pattern noise to appear throughout the scene.
