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 product has a compensation function and the problem
may be alleviated by automatic black balance adjustment
(see page 59).
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.
