A device, or circuit in a device, which converts interlaced video to progressive scan video. Interlaced pictures are painted in two passes. Every other line is painted in the first pass and the alternate lines are painted on the second pass. A line doubler, aka deinterlacer, creates a complete picture, filling in all of the lines, for each scan. More lines results in a better picture.
A video processor that doubles the number of lines in the scanning system in order to create a display with scan lines that are less visible. Some line doublers convert from interlaced to progressive scan.
A video device which enhances picture quality by deinterlacing the picture into progressive frames.
This advanced technology scans the incoming picture and then reproduces the picture with twice as many "lines" of information. These extra lines decrease the jagged edges and improve the richness, or texture, of the image.
A device intended to synthesize a picture with twice as many scan lines with or without interlacing in the final result.
a device used to enhance video signals prior to display
an electronic device that converts analog or digital television (TV) video signals into a format suitable for display on a computer monitor
A device that that doubles the number of scan lines in a video picture. This fills the space between the lines of an interlaced signal, improving the image.
A video processor that can double the number of lines in a scanned display, making each of the lines smaller, and therefore less visible. One common form of line doubler converts an interlaced picture into a progressively scanned picture. See: Interlace, Progressive Scan, IDTV
Specially designed device to double the number of Scan Lines in an (usually) NTSC monitor or projector. Enhances picture quality by reducing jitter and video artifacts.
Electronic device meant to enhance a video picture by doubling the number of broadcasted lines per frame.
An Increased Definition Television (IDTV) feature that doubles the number of scan lines in a video picture. This fills the space between the original lines, making them less noticeable and increases the brightness of the picture. For example, the NTSC video field of 262.5 lines is doubled to 525 non-interlaced lines and the PAL field of 312.5 lines becomes 625.
Electronic device or circuit turning video signals (half images) coded by the interlaced scanning into full images. The Line Doubler removes the annoying line structure. The simplest form doubles the provided lines. This results in homogeneous images
A device that converts NTSC, or S-video and related video formats to VGA format. In order to convert the original video signal's 15.75KHz horizontal line rate to VGA's 31.5KHz rate, each line of the original signal is duplicated at the VGA rate. Each 240-line field of the original video signal becomes a 480-line VGA frame.
This is simply a de-interlacer. For instance it could take a 480i picture and double it to 480p, thus taking an interlaced image to progressive. A doubler can also take a 480i image and convert it to 960i, as the 240 lines being shown in 1/60 are the same as showing 480 lines at 1/60 second. Bob is a line doubling technique that repeats the last line to create new lines. Weave is another technique that combines one half the image (here being 240 fields) with the previous or next 240 fields to create a single 480 line frame.
A line doubler is a device used to deinterlace video signals prior to display.
