Video Processing

Synaptics multimedia processors leverage Qdeo video processing technology to deliver consistently high-quality results whether viewing pristine 4K/UHD or lower resolution sources. The Qdeo suite of "quiet video" technologies produces full resolution video with superb clarity and accuracy, whereas conventional alternatives may produce noise and distortion that are distracting on today's high-quality displays.

Qdeo technology video processing occurs in three main stages:

Video Processing - Stage 1

Noise Reduction reduces analog and/or digital noise while minimizing side-effects.

Most video material contains analog and/or digital noise. Noise Reduction refers to the process of reducing this noise while minimizing any side-effects. 3D per-pixel motion-adaptive Video Noise Reduction (VNR) completely removes flickering dots from a stationary background and in moving areas without causing side-effects like blurring, ghosting (double imaging) or loss of detail. Per-pixel content-adaptive Compression Artifact Reduction (CAR) removes block and mosquito noise without causing side-effects like blurring or loss of detail.

Stage 2: Format Conversion

Most video material needs to be converted from its original resolution to match the native resolution of the display.

Most video material needs to be converted from its original resolution to match the native resolution of the display. 3D per-pixel motion and edge adaptive de-interlacing produces full-resolution in regions where there is no motion and smooth and clean edges for moving objects. Vector Interpolation calculates the direction of the edge to interpolate in that direction, thereby rendering a smooth image without objectionable jagged edges. Qdeo Film Mode does inverse telecine of the film-originated material by identifying the correct film cadence and weaving together the appropriate fields. In addition, Qdeo de-interlacing is able to correctly identify video and film material when they are mixed together—as sometimes occurs in broadcast TV—and handles the content appropriately to avoid the introduction of feathering artifacts in the video content.

Stage 3: Enhancement

Enhancement improves contrast, brings out detail, makes colors more vivid, and creates a greater sense of depth.

Qdeo enhancement is the process of enhancing the appearance of the image by improving the contrast, bringing out the detail, making the colors more vivid, and creating a greater sense of depth. These enhancements can be done once the inherent noise is removed and the image has been converted to the desired display format. Adaptive Contrast Enhancement (ACE) expands details in the shadows without crushing the mid-tones or highlights. Intelligent Color Remapping (ICR) enables vivid colors in outdoor scenes without causing hue shifts or loss of detail or changes in skin tones. It provides the ability to enhance certain colors in the spectrum while leaving other colors untouched. And Natural Depth Expansion (NDE) brings out fine details in textured regions like walls and grass and sharpens boundaries of objects like windows and grills, without introducing side-effects like halos and ringing.
