Aspect Ratio Control: Allows selection from standard aspect ratios, such as common top & bottom, common sides, 14:9 and Anamorphic. In addition, it allows for Flexview, a non-linear anamorphic aspect ratio
, to be used in up-conversions.
Detail Enhancement: Is an edge-sharpening filter based on a traditional film compositing technique called "Unsharp Masking." This filter corrects any blurring introduced during image capture, compression or resampling.
Noise Reduction Adjustable noise reduction controls offer a greater degree of temporal recursive noise reduction with fewer artifacts. A bias control allows the aggressiveness to be fine-tuned. For filter performance testing, a Red Overlay can be applied that will color pixels that are in motion in Red
Up-/Down-conversion:In situations where the highest image quality up- or down-conversion is necessary, Link’s HDU-925 uses proprietary PixelMotion™ De-interlacing and Detail Enhancement combined with powerful array processing to provide the best image solution.
APPLICATION: The first step in the conversion process is to identify whether the input material is video or film originated. The identification process happens in a fully automatic mode and selects either PixelMotion De- interlacing for video based material or 3:2 Detection for film based material. The goal is to apply the appropriate filter in order to recover the full vertical resolution of the input material.
PixelMotion de-interlacing produces perfect progressive frames in preparation for further processing. The processing aperture is adjusted on a pixel-by-pixel basis, which preserves all of the detail of the original interlaced image. Additionally, the filter eliminates “jaggies” in the output image, providing well-defined edges on objects and producing the sharpest images possible.
3:2 Detection recognizes the redundant fields inserted by the telecine during the conversion of film to video. This advanced 3:2 pull-down filter avoids frame rate conversion artifacts and provides the highest vertical resolution and motion quality.
Since the quality of the video de-interlacing is so high, there will be no difference visible in the vertical resolution seen with film originated material and that of the de-interlaced video originated material.
Once the image has been de-interlaced and up-converted, Detail Enhancement can be applied to the image to further sharpen and enhance the output. This filter adds an additional level of image quality by helping to better define the detail in the up-converted image. Detecting the edges of objects and adjusting the contrast ratio around those objects to help separate them from the Background achieve this.
