Basic Functions
Noise Reduction
The NR (Noise Reduction) function removes noise
(both random and non-random) to provide clearer
images. By combining 2D filtering according to
brightness and image color, and 3D filtering according
to noise caused by motion and time difference, lower
noise images can be obtained for the corresponding
image brightness of a moving subject.
This function has six steps: levels 1 to 5, plus off.
Level 1 applies to subject motion mainly using 2D
filter effects. With level 5, 2D and 3D filter effects are
maximized, providing the lowest-noise images,
although moving subjects may show trails.
At each level, two filters are set according to noise and
image motion characteristics, so the available level
selections depend on the situation. The default setting
is level 3.
Image Stabilizer (EVI-D90N/P only)
Switching ON the Image Stabilizer function reduces
image blurring caused by, for example, vibration,
which allows you to obtain images without much
blurring. A correction effect of approximately 90% is
possible for a vibration frequency of around 10 Hz.
The Image Stabilizer function employs the digital
zoom system, so the angle of view and resolution are
changed, but the sensitivity is maintained.
Hold Function of Image Stabilizer
With the Image Stabilizer function, suddenly stopping
high-speed movement (pan, tilt, etc.) of the camera
produces a blur sensor counteraction that may cause
image movement. In such a case, you can use a
command setting (hold) to maintain the correction of
the Image Stabilizer function. In this case the image
stabilizer is off, but there is no change in the angle of
view.
