A more advanced version of a Comb Filter that actually samples the picture information and makes corrections as it separates the color from the black & white. The results are improved detail and reduced "dot crawl" i.e. the little jagged edges that seem to shimmer where different colors meet on the screen.
A type of filter that digitally separates the colour and black and white components of a television picture. Doing this improves picture sharpness and is more effective in reducing the number of "artifacts" and "shimmer" than analog comb filters. (See also 3-line Digital Comb Filter)
Filter that digitally separates color and black and white signals in your TV, providing a sharper picture and reducing artifacting and shimmer. The best digital comb filters, called 3-line digital comb filters, compare three lines of video to ensure the best possible picture.
Digital filter which clearly separates the combined color and black-and-white video signals, preventing cross color interference also known as dot crawl and hanging dots.
See comb filter definition.
Digital circuitry cleanly separates black and white detail from color data virtually eliminating dot crawl and delivering unmatched, razor-sharp picture performance with 800+ lines of horizontal resolution.
Clear separation of the combined colour and black and white signals, preventing smudging, vibrating edges and ensuring precise details
Separates combined colour and black and white picture information to provide a sharp picture.
digital comb filter is used to separate brightness and color information from a composite video signal. Color and brightness is recombined to isolate red, blue, and green content to produce the picture. The comb filter has a frequency that looks like the teeth of a comb and the filter alternately accepts and rejects small bands of frequencies. Comb filters are used in mid grade to more expensive TV sets. The main types of digital comb filters are: 2-line digital, 3-line digital, and 3D digital. 2-Line Digital Comb Filters 2-line digital comb filter compares consecutive lines within a video field and adjusts to reduce cross color interference. 3-Line Digital Comb Filters 3-Line Digital Comb Filters compares 3 lines within a video field and reduces dot crawl and color bleeding. 3D Digital Comb Filters 3D digital comb filters almost eliminates dot crawl and color bleeding entirely by scanning not only consecutive lines within a video field, but also the preceding and following fields. The result is improved color purity.
Converting chrominance and luminance signals into digital format for enhanced color purity and reduced dot crawl.
