Full functionality description
In the table below, the settings for each preset are summarized:
Table 1: Resizer settings - presets
Sharpness: Sets the sharpness of the displayed image. Sharp images may introduce unwanted
ringing in the image. The sharpness is thus always a compromise between “sharpness” of the
image and reducing the presence of “ringing”.
•
Sharp (see figure below-d): This setting applies a cut off of the unwanted higher frequencies in
the input signal as much as possible.
•
Normal (see figure below-e): This setting is applied by most display units and applying this set-
ting results in a moderate cut off of the unwanted higher frequencies.
•
Smooth (see figure below-f): This setting introduces a gradual cut off of the higher frequencies
in the input signal.
Anti-aliasing: Selection of algorithms designed to reduce the aliasing effect in processed images.
The filter template for Y’ and R’G’B’ components is used as guideline to meet with the requirements
for the broadcasting community. This setting is a compromise between “sharpness” of the image
and reducing unwanted anti-aliasing effects.
•
Boost (see figure below-a): Anti-aliasing is set to an extreme value. This setting is not advised
to display video content.
•
Balanced (see figure below-b): This type of anti-aliasing is applied by most display units and
results in a moderate setting.
•
Conservative (see figure below-c): This setting is preferred for video signals and results in a
strong reduction of anti-aliasing effects while preserving good sharpness of the image.
