Runco virtual high definition processor with aspect ratio control Luma Enhance, Chroma Enhance

MENU DESCRIPTION AND NAVIGATION

• SHARPNESS

This controls the ‘high-frequency’ detail of the image. The more sharpness is increased, the more detail is added into the picture. However, if it is increased too much, it will also increase ‘noise’ in the picture as well as other types of artifacts. This may be set to personal preference; midrange is factory-preset.

• LUMA ENHANCE

This is similar to the sharpness control, but it does not boost the frequencies all over the picture. Instead, this is more like an ‘edge enhancement’ that makes transi- tions between objects more or less defined. The edges of a building, for example, may appear more or less defined depending on the setting of LUMA ENHANCE. This affects areas of the image that do not have much color.

The LOW and HIGH FREQUENCIES setting on the bottom of the LUMA ENHANCE adjustment window are for different sources; it should be set to LOW FREQUENCIES if a lower quality source is used (VCRs), and HIGH FREQUEN- CIES if a good quality source like a DVD player is used. To select HIGH or LOW FREQUENCIES, use the ENTER button.

• CHROMA ENHANCE

This is basically the same as LUMA ENHANCE, but affects the color edges.It helps remove the watercolor look of NTSC images. Use low frequency for VCRs and cable and high frequency for DVDs.
