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 setting results in a moderate cut off of the unwanted higher frequen-
cies.
• 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.
