Phenomena Specific To Ccd Image Sensors - Sony Power HAD EX DXC-D55PK Operating Instructions Manual

Important Notes on Operation
Phenomena Specific to CCD
Image Sensors
The following phenomena that may appear in images
are specific to CCD (Charge Coupled Device) image
sensors. They do not indicate malfunctions.
White flecks
Although the CCD image sensors are produced with
high-precision technologies, fine white flecks may be
generated on the screen in rare cases, caused by
cosmic rays, etc. This is related to the principle of
CCD image sensors and is not a malfunction.
The white flecks especially tend to be seen in the
following cases:
•when operating at a high environmental temperature
•when you have raised the master gain (sensitivity)
•when operating in Slow-Shutter mode
This problem may be alleviated by automatic black
balance adjustment (see page 81).
Vertical smear
When an extremely bright object, such as a strong
spotlight or flashlight, is being shot, vertical tails may
be produced on the screen, or the image may be
distorted.
Monitor screen
Aliasing
When fine patterns, stripes, or lines are shot, they may
appear jagged or flicker.
