Phenomena inherent to CCD imaging device
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.
3) Moire
Interaction between patterns can produce an additional "phantom" pattern to appear. The CCD picture
elements (pixels) are arranged in a pattern, which can interact with a pattern in the scene (e.g., a performer
wearing a finely striped necktie) to result in a Moire pattern. The effect should be considered when selecting
costumes, props and other scene elements.
4) Ghosting
Strong direct or reflected light near an object of interest can cause ghosting of the object to appear in the
picture. The effect is more obtrusive with certain iris settings and lens types. Select the scene layout and
camera pointing direction carefully in order to avoid this effect.
Operating considerations Notes to users
1. Important safety notes
・ Use this camera with a 12VDC power supply,
・ Observe that flammable objects, water or metal do not enter the camera interior. These may lead to failure or accident.
・ Do not modify the camera or use the camera with external covers removed. These may cause failure, void any warranties
and pose a safety hazard.
・ Sop using the camera at the approach of electrical storm (thunder audible). Protect the camera from rain if using it
outdoors.
・ In event the camera shows any abnormality, switch off the camera and disconnect the power cord. Contract a Hitachi
Denshi service representative.
2. Handling
・ Do not attempt to remove cover.
・ When installing or removing a lens, be sure to use care that water or dust dose not enter the inside of the camera.
3. Installing and storage
Avoid installing or storing the camera in the following environments.
・ Environments exposed to direct sunlight, rain or snow.
・ Environments where combustible or corrosive gas exists.
・ Excessively warm or cold environment (Operating ambient temperature: -10 to 50℃).
・ Humid or dusty environment.
・ Place subjected to excessive vibration or shock.
・ Environment exposed to strong electric or magnetic field.
・ Do not aim the camera lens at the sun.
・ Do not shoot strong light.
When such a scene is shot, vertical trailing will appear. However, this is not due to failure. In case strong light enters camera
through the lens, partial deterioration in picture quality will result.
4. To obtain stable performance for long time
When the camera is used continuously for long time under high ambient temperature, the inside electrical parts become
deteriorated, resulting in shortening its life. To use the camera continuously for long time, the highest temperature must be
below 40℃.
5. Connectors
Confirm the power is off before connecting or disconnecting a signal cable. Grasp connectors by the body, not the attached
wires.
