Most computer monitors, and some high-definition TV sets use progressive scan, as opposed to the NTSC standard of interlaced. In progressive scanning, all the horizontal scan lines for a single frame are painted on the screen from top to bottom in a single pass. DTV formats usually include both interlaced and progressive display methods. Progressive or non-interlaced video produces a higher quality image. Interlaced video suffers from flicker problems due to the full image not being displayed and from alignment problems where the odd lines do not exactly line up with the even lines. Such alignment problems can be particularly bad in video containing fast moving images.

Process of creating a 720p or 480p image on an HDTV monitor by displaying horizontal and vertical picture information on a screen simultaneously.

This is the opposite of interlaced scan.

Technology that creates DVD Images in one continuous Scan. Gives clearer, flicker free Images than the Conventional Interlaced System, which creates Images using Rapidly refreshed Horizontal lines.

A non-interlaced refresh system for monitors that cuts down on CRT flicker.

Complete picture. The normal Pal-image consists of half pictures. Some DVD players are able to display complete pictures instead of half pictures, which leads to a considerable increase of image quality.

Video signals are generated using horizontal lines. An interlaced picture ...

Some digital television broadcast formats (720p, 480p), and some higher-end DVD players, use a type of video signal known as progressive scan. Instead of splitting each video frame into two sequential fields like standard interlaced NTSC video, progressive-scan video displays the entire frame in a single sweep. So, where standard NTSC video displays 30 frames (60 fields) per second, progressive scan displays 60 full frames per second. Displaying progressive-scan video requires more bandwidth (there's twice as much vertical information) and a faster horizontal scan frequency than interlaced video. Progressive-scan picture quality is more filmlike, with more fine detail and less flicker. For progressive-scan viewing, you'll need a TV that's HDTV-ready.

New CCD design, allowing acquisition of both even and odd fields at the same time. In this type of sensor there is no integration of signals between adjacent lines, so each pixel contains information from one complete frame. While progressive scan method provides signals from all pixels during a single exposure, it is possible to obtain image signals delivering both high vertical and dynamic resolution without a mechanical shutter, which is impossible with a conventional CCD. The progressive scan CCD is ideal for use where rapidly moving objects must be captured with high resolution, such as in image measurement and image processing applications. Frame shutter - An electronic shutter mode where full frame image data is read out during single exposure.

Each frame of a video image is scanned complete, from top to bottom, not interlaced. Progressive scanning requires more bandwidth than interlaced scanning, but it eliminates artifacts that result from interlacing. It is commonly used in computer monitors and high-definition televisions.

A display where all horizontal lijnes are displayed simultaneously in a single frame, as opposed to an interlacing system that shows two separate alternating fields.

Progressive scan is a method of displaying an image on a cathode ray tube like a standard television (not an LCD or plasma screen.) A progressive scan system displays the entire image once every sixtieth of a second. The true framerate is therefore 60 frames per second.

Conventional TV pictures are made up of two fields, each one comprising alternate lines of the 625 used to make up a PAL TV picture or the 525 used in NTSC. Your eye is fooled into seeing a whole picture by the speed of the scanning. Progressive scan improves picture quality by scanning the whole field in one hit, not just half of the lines at a time, but to take advantage of this you need a video source - usually a DVD player - and a display device such as a TV or projector - capable of supporting this system. Progressive scan is currently only really relevant with NTSC signals, but work is being done to apply it to the British PAL TV system too.

Progressive scan, as opposed to interlaced video, scans the entire picture, line by line every sixteenth of a second. In other words, captured images are not split into separate fields as in interlaced scanning. Computer monitors do not need interlace to show the picture on the screen, but instead show them progressively, on one line at a time in perfect order i.e. 1, 2, 3, 4, 5, 6, 7 etc., so there is virtually no "flickering" effect. In a surveillance application, this can be critical when viewing detail within a moving image, such as a person running. A high-quality monitor is required to get the best from progressive scan. See also interlacing.

A method of drawing a picture frame on a television screen in its entirety without drawing two separate fields. The picture is drawn from left to right and top to bottom in one scan without skipping any lines. This method reduces the flicker of the picture on the television screen and results in smoother motion on the screen.

Progressive scan means drawing the odd and even scan lines in order without interlacing. Progressive scan by itself does not improve resolution. We still have the same 480 (for NTSC) illuminated scan lines' worth of picture detail. One reason for progressive scan is to reduce flicker.

A video display where an entire frame is drawn in a single sweep, instead of as fields consisting of either odd or even scan lines, as with the interlaced NTSC system. This results in greatly reduced flickering and artifacting, and a more film-like image overall.

Is a Non-Interlaced signal where all video scan lines are drawn in one frame instead of two This reduces artifacts and flicker that can result from the interlacing of odd and even fields.

The way a television decodes an image – also known as non-interlaced, the odd and even fields are scanned sequentially (1, 2, 3, 4…) every 1/60 of a second. 60 frames are produced every second, thus creating a smother, more vivid picture with less flicker. It is the same technology computer monitors use.

A television with progressive scanning can generate a picture in a single pass, in a similar way to a computer screen. High-end DVD players also support this technology. Compare with conventional interlaced scanning, which needs two passes to generate a picture, the first pass for the odd-numbered scan lines, the second for the even-numbered scan lines. Progressive scan has a refresh rate of 60 times per second, double the speed of conventional analog TVs, so the picture looks sharper, more solid and more cinematic. AT the moment progressive scan is only available on NTSC DVDs.

A method of image scanning that processes image data one line of pixels at a time, creating frames composed of a single field (as opposed to interlaced scanning, which meshes two fields, each composed of alternating scanned lines, per frame).

A DVD player with progressive scan can use the extra lines of resolution on an anamorphic DVD to improve the sharpness of the image when viewed using a compatible television.

Scanning method whereby each row of pixels is sequentially scanned as opposed to interlaced scanning whereby all odd pixels are scanned, then all even pixels.

A type of video display where each horizontal line is scanned consecutively from top to bottom, resulting in a full frame of video without the need for fields. (Compare to interlaced scan.)

A video display that scans all lines sequentially in each pass. A Line Doubler can create a progressively scanned image from an interlaced scan signal. See: Line Doubler.

A display which scans consecutive lines of a screen at a rate of 60 times a second.  This offers a smoother image than interlaced which scans every other line of a screen at 30 times per second. Also see:  Interlaced

A picture scanning process where all the lines of the image are scanned by every vertical scan. This is also called Non-Interlace Scanning.

Progressive Scan doubles the number of visible picture lines per field by displaying all picture lines at once. Frames are drawn in order of all lines, 1,2,3,4, etc. which eliminates line flicker.

The opposite of interlaced. All the lines are scanned sequentially.

the way a screen displays the image you see before you in a full picture per each frame, rather then the interlaced method in which it shows you the odd lines, then even. This shows you all lines at once. Ex: Computer Monitor

A method by which image detail on a TV picture is enhanced by showing both halves of a single frame at the same time, as opposed to showing only half a frame at a time

The conventional television system has 525 scan lines making up a frame, but these are scanned in alternate interlaced passes of the 262.5 odd scan lines and the 262.5 even scan lines (in the case of the NTSC color system). Since its frame rate is 30 frames per second, one of these passes, termed a field, occurs every 1/60 second. In distinction to this, a progressive scan is one where all of the lines are scanned successively in a single pass. By saving a field in memory, it is possible to convert an interlaced video signal to a progressive scan, which then allows the image to be refreshed every 1/60 second reducing flickers on a large screen.

Progressive scanning of the video signal consisting of two half images. Both half images are added to one full image. Thus subtle structures can dissolve To top

Term used to describe an image sensor that gathers its data and processes each scan line one after another in sequence. See also "Interlaced" for the other method.

The TV image is drawn or refreshed from top to bottom of the picture progressively (1 line after another). Progressively scanned images must be scanned faster than interlaced, to avoid the viewer "seeing" only part of the picture, instead of a full frame.

The process of scanning lines sequentially… One field produces one frame.

proper scanning of video frames top to bottom, never skipping a line, resulting in coherent freeze-frames. Detailed description

Progressive scan adds three dimensional and flicker free picture quality. A progressive display produces an entire frame of all visible lines of resolution, rather than the interlaced format of displaying odd lines on one frame followed by even lines on the next frame. Progressive scan devices also process information at a higher rate, which allows for a high color resolution.

the means by which the picture tubes of computer monitors and newer televisions display images. The process uses a progressive scanning tube to send information to each pixel on a screen sequentially—left to right, top to bottom—to create the image. The 720p (progressive) high-definition standard is a progressive-scanning standard. Progressive scan offers higher-quality pictures than does interlaced scan.

An advanced method of viewing video images that provides better quality than traditional interlaced images.

All horizontal lines of the frame are shown in one go. So will deliver a superior picture from a DVD or video player.

A video scanning system that displays all lines of a frame in one pass. Contrast with interlaced scan.

The process of imaging a picture by having the numerous scan lines that form it laid down continuously, eliminating artifacts that result from interlacing. Commonly used in computer monitors and high-definition television sets. See also Interlaced scan

Progressive scan displays the entire video frame in a single sweep at 60 frames per second. The result is less flicker and incredibly detailed images. You do need an HDTV ready TV for progressive scan viewing.

A method of scanning a TV display where all lines in a frame are displayed in sequence from top to bottom. This is the alternative to interlaced scan and also involves an increase in frame rate from 25 Hz to 50 Hz or 30 Hz to 60 Hz to avoid flicker.

A scanning system for video screens where each line is displayed progressively (1,2,3,4...) as opposed to interlaced (1,3,5...2,4,6...). Computer monitors use progressive scan. Some of the new HDTV standards call for progressive scan.

All horizontal scan lines of a video frame, even and odd, are beamed to the screen at one time, from top to bottom. Unlike interlaced scanning, progressive scanning eliminates the need to separate each frame into two fields. Therefore it takes half the time to display an entire frame of video. This doubles the frame rate to 60 full frames per second. Newer LCD and flat-screen displays are inherently progressive.

Each frame of a video image is complete, from top to bottom, not interlaced. For example, 480p means that each image frame is made of 480 horizontal lines drawn vertically. Computer images are all progressively scanned. Requires more bandwidth (twice as much vertical information) and a faster horizontal scan frequency than interlace images. The magnification of resonance factor of any resonant device or circuit. A driver with a high Q is more resonant than a driver with a low Q.

Is a superior way of viewing video images compared with the traditional interlaced method. With interlacing, the two fields of each video frame (the odd and the even horizontal lines) are shown one after the other. With progressive scanning all of the horizontal lines of the frame are displayed in one go. The advantages are a lack of 'flicker' and jagged edges, typical of interlaced displays like CRT TVs, and also smooth horizontal resolution. A number of DVD players can output video progressively, although it is only officially available with NTSC material. The signal must be fed to a non-interlaced display such as a plasma screen, or LCD or DLP projector. Certain TV's also feature progressive scan (or deinterlacing). Such sets analyze the video signal and insert extra scanning lines to increase the apparent resolution (compare with 100Hz scanning).

Method of displaying video images in which every horizontal line is drawn on screen in a single pass to create a complete frame or single full-screen video image. This is in contrast to interlaced images which draw the odd lines and then the even lines in two separate fields to create the final frame. Since fewer lines are projected at any given time using the interlaced format, there is a subjective degradation of picture quality and resolution compared to non-interlaced video.

The progressive scan format outputs data from the camera (the signal) in sequential order as it is scanned. The scan format produces a full frame of video in a continuous stream, rather than half the image per output sequence(interlaced image) in traditional RS-170 CCD cameras. Standard RS-170 video is interlaced and output in two separate fields, generating essentially half the image at a time.

Ability of the video camcorder to record all lines of an image to the tape for every frame of video. Cameras with progressive-scan CCDs read each row of pixels on the CCD sequentially when recording an image. Older models of CCDs either read a pair of rows at a time or read all even rows as one frame, then all odd rows as the next frame. Both of these older methods compromise image quality.

The process whereby a picture is created by scanning all of the lines of a frame in one pass. See also Interlaced Scan. The process of converting from interlaced to progressive scan is called "line doubling."

The progressive scan is a format for reading an image in sequential order, line by line.

See Non-interlaced.

This method displays the full picture frame at the same time. Most computer monitors work this way, giving a sharper better-quality picture. A display notation of 1080p indicates it uses a progressive scan. In digital TVs, 480p is the minimum standard for high definition.

Bij een (moderne) computermonitor wordt deze manier van scannen door de electronenstraal toegepast. Het volledige beeld ('frame' genoemd) wordt in één keer van links-boven met horizontale lijnen naar rechts-onder afgebeeld in licht op de beeldbuis. Interlaced mode is het 'tegenovergestelde' van progressive scan.

An alternate means to interlaced video used to create images on screen. Progressive scanning reproduces an entire video frame in a single pass, from top to bottom thereby reducing flicker, improving contrast and producing a more film-like result.

Realises DVD image frames in their entirety, allowing for flicker-free clearer images. Traditionally, a system of interlacing was used, where rapidly refreshed horizontal lines were interchanged to recreate the overall image.

A video scanning system that displays all lines of a frame in one pass instead of interlacing them.

A Progressive Scan is an improved scanning format for television systems. Where a standard television uses an interlacing format (alternating lines 60 times a second, creating a full image 30 times a second) higher market televisions and digital television systems use progressive scanning in which the television scans all the lines on the television in succession, and does a full screen 60 times a second. The result is a doubling of the frame rate and drastically improved picture quality.

See Interlaced vs. Progressive Scan.

Progressive or noninterlaced scanning is any method for displaying, storing or transmitting moving images in which the lines of each frame are drawn in sequence. This is in contrast to the interlacing used in traditional television systems.
