CC5MPX Digital Camera

8.10 Image Quality
Lighting conditions have the greatest influence on image quality. The
CC5MPX camera produces the best images under normal daylight conditions.
Pictures taken in good daylight conditions produce crisper and brighter images,
as the camera uses the entire image to adjust the exposure settings of a scene.
Scenes that contain small variations in light intensities will produce better
exposed images. In scenes with high variations in light intensities, such as a
bright sky or a dark horizon, the image may contain portions that are under-
exposed and portions that are over-exposed, as with most cameras. The
CC5MPX utilizes various techniques to produce an overall good picture under
most lighting conditions.
8.10.1 Night Time Images
In general, the camera does not produce good images at night. If lighting is
present, such as street lights, then distinguishable pictures can be taken.
8.11 Lens
The standard and zoom lenses for the CC5MPX contain the following features:
•
C-Type Mount
• Varifocal (manual zoom)
•
Manual Focus
•
DC Iris
Access to the lens for adjusting the zoom and focus requires the removal of the
CC5MPX lens tube (see FIGURE 8-47 ). The lens tube is threaded on and
needs to be turned counter clockwise to be removed.
The zoom and focus adjustments are shown in FIGURE 8-48 . The
thumbscrews may need to be loosened prior to moving the adjustments. It is
important to tighten the thumb screws once the camera focus and zoom
adjustments are completed, to avoid problems from vibration.
The camera controls the iris of the lens using the cable with a 4-pin connector.
This connector must always be plugged into the receptacle (on the front lens
plate of the camera) for proper operation.
