A display technique in which each TV picture, or frame, is produced using two sequential fields. One field contains the off-numbered lines of the frame, and the other the even-numbered lines. The TV tube, or image, is scanned twice, with the lines of two fields interweaved, or interlaced. The technique eliminates visible flicker which can be annoying at low frame rates.
graphics are often converted to an "interlaced" format. Interlacing causes the graphic to display on the web page as it loads, thus giving the illusion that the graphic is loading more quickly. A "blurry" version of the graphic appears first and details are added later. If graphics are not interlaced, the browser will display the graphic only after it has loaded the entire file. (The larger the graphic file size, the more noticeable the difference garnered from interlacing.)
A common way to compress video is to interlace it. Each frame of an interlaced ...
Images that are displayed progressively as they download. Interlaced images appear to come into focus gradually in contrast to images that are not interlaced, which are drawn from top down as they download.
A type of monitor that produces a certain amount of flickering compared to non-interlaced which reduces that flicker.
Interlace scanning is a method that can produce two images in a single scan, by scanning every other line. For example, if there are 480 scanning lines, only the oddnumbered lines are scanned for the first image (1, 3, 5, ... 479), and all the even-numbered lines are then scanned for the next image (2, 4, 6, ... 480). Interlace scanning has the advantage of displaying smooth movement. See Progressive Scan.
This refers to a type of display where the electron beams alternate between scanning the even numbered lines and then the odd numbered lines, resulting in the two vertical scans on the screen, with the field (each set of lines) being updates 60 times a second, and with the frame (both fields) updated 30 times a second.
Interlaced involves two passes when painting an on-screen image, painting every other line on the first pass and filling in the rest on second pass, causing flicker on display. Non Interlaced paints all of the lines in one pass and then paints an entirely new frame. Non interlace monitors deliver flicker free images, making them more preferable over less expensive interlaced monitors.
The pattern described by two separate field scans when they join to form a complete video frame. The two field scans interleave together to form a single, complete frame.
A scanning method that divides the screen into two fields, alternately drawing odd-numbered and even-numbered scan lines. A scheme to display a video image by displaying alternate scan lines in two discrete fields. Interlaced signals are used in broadcast video and are required for video to be compliant with NTSC.
The drawing of every other, or selected lines, so that a rough image can be displayed before the entire image is loaded.
Interlacing is a method to send picture data over the Internet. When a picture is interlaced, the following occurs: After one sixty-fourth of the picture is downloaded, you can see a general image of what the picture looks like. As more of the picture is downloaded, the resolution improves until the whole picture is displayed.
Every other line is scanned during each total vertical (full) screen refresh.
A method of displaying video, in which the odd and even scan lines are displayed separately. This method is used by the current television standard in North America, NTSC, for legacy purposes (when it was developed in the 1930s, the available display phosphors did not allow for a quality progressive-scan image).
Short for interlaced scanning. Also called line interlace. A system of video scanning whereby the odd- and even-numbered lines of a picture are transmitted consecutively as two separate interleaved fields. Interlace is a form of compression.
a technology used in a standard television display
Process of creating a television picture by sequentially drawing odd and even lines on a screen. The process is used by NTSC and several digital television signals.
A type of display in which the electronic beam of a monitor draws every other line with each pass, which lessens the overall effect of a lower refresh rate.
A video scanning system in which all of the lines in the frame are scanned alternately.
An attribute of video (especially NTSC video) where frames have been weaved together in order to take advantage of the display methods of televisions. (More)
Monitors draw an image every other line, before the monitor goes back to the top and fills in the lines missed. Can result in flickery images.
In television, a scanning format where each video frame is divided into two fields. One has the odd numbered horizontal scan lines, the other the even numbered lines. Each field is then displayed on an alternating basis. The purpose is to eliminate "flicker" of the viewed image. (compare with Progressive scanning).
A scanning technique in a video system where odd and even horizontal scan lines of a video frame are displayed during alternating update cycles.
A method whereby two interleaved fields are used to generate a single video frame. With interlacing, a single frame (in NTSC, 525 lines) is split into two fields of 262.5 lines. Each line is "drawn" on the screen consecutively, first one, then the other.
Interlacing is a method to send picture data over the Internet. When a picture is interlaced, after one sixty-fourth of it has been downloaded, you can see a general impression of what the picture looks like. As more of the image is downloaded, resolution improves until the entire picture is displayed.
A process by which a single frame of a TV signal is presented in two halves, known as â€˜fields
A procedure that displays an image in coarse form first, followed by finer detail. This allows you to get an idea about an image without having to display the entire image first.
This is an image formation where initially a half image (every second image line) is produced and thereafter the second half image is placed in the gap. Due to the double image frequency the flickering is reduced. All normal video norms work according to this principle while HDTV is working without line skip. Interlace is no longer common with data images
Term used to describe an image sensor that gathers its data by first processing the odd lines and then the even lines. See also "Progressive Scan" for the other (preferred) method.
Method of significantly increasing data densities at conventional horizontal scan rates.
The scanning process which combines the odd and even fields to produce a full video frame.
This means that the graphic data is split (usually into two parts), and is displayed alternately line by line. The first pass draws every even line, and...
When the monitor cannot repaint a screen in one burst but draws it is section which may apper as flickers.
A type of video stream made up of odd and even lines (or sometimes columns). Normal TV signals (like PAL & NTSC) are interlaced signals, made up of two odd and even line images called fields. These odd and even fields can be used to store stereoscopic left and right images, a technique used on 3D DVDs, although this halves the vertical resolution of the video.
An interlaced image is created when the cathode ray fills in even-numbered horizontal lines on one pass, and then odd-numbered lines on the second pass. This process, found mainly in older monitors, can create some onscreen flicker.
The combination of two separate fields joined together to form a single video frame.
A method of scanning a screen which results in alternate lines being drawn with each full pass of the electron beam. The resulting display is less stable than a flicker-free non-interlaced display.
A system that skips every other line of a picture on the first pass, then fills in those lines on the second pass. When talking about resolution, this method is indicated by "i" after the number of lines, as in "480i" or "1080i". When you watch analog television, you're looking at an interlaced video display. Because early television tubes couldn't draw the whole screen before the top began to fade, TV engineers implemented interlacing. This system might result in a little flicker, but it avoids having the bottom of the screen perpetually brighter than the top. On digital TVs, as on computer monitors, the whole screen is "progressive" (drawn line by line).
Short for interlaced scanning. A system of video transmission whereby all the odd number lines are delivered followed by all the even numbered lines. These two â€œfieldsâ€ combine to form a single frame of video.
An analog video signal consisting of alternating odd and even fields. The two fields are superimposed to create a single frame. See also interlaced odd and interlaced even.
A method of displaying a video image in which all the odd lines are drawn first and then all the even lines are drawn next.
A format of video display. Video is produced by updating the odd-number lines on the first scan and the even-numbered lines on the second scan.
A method of refreshing the image on a monitor. Instead of refreshing the entire image (non-interlaced), an interlaced monitor refreshes the odd-numbered scan lines first, then refreshes the even-numbered scan lines on the second pass. This reduces the amount of new information that has to be passed on each sweep, but causes almost unnoticeable flicker, that can result in eye fatigue.
Interlaced video is created by capturing every other line of an image, every other frame of the video. Because the images are played back in quick succession, it appears that a complete image is being created.
Display in which the monitor only draws every other line.
A system of video scanning where odd- and even-numbered lines of a TV picture are transmitted consecutively as two separate interleaved fields. Interlace is a form of compression and has been used for decades in analog (NTSC) TV.
Standard NTSC television signals are interlaced, meaning that each video frame is divided into two separate fields of alternating scanlines. The resulting fields are displayed sequentially, such that what was originally a 30 frame per second (fps) refresh becomes 60 Hz at half the vertical pixel addressability. Thin horizontal lines will appear to flicker on an interlaced display since their effective refresh rate is only 30 Hz.
This is the traditional way, and still the most common one, for a TV display to scan visual information. It splits each frame into two fields and combines them as odd and even lines. A display notation of 1080i means the display uses interlaced scanning.
camera Interlacing is when every other row of pixels on a digital sensor are processed and then the previously skip rows are processed. RS-170 is the EIA (Electronics Industries Association) standard for black and white interlacing used in North America, Japan, and a few other regions. CCIR is the standard used in Europe and many other parts of the world. See Progressive scan.
Two horizontal video scans (odd, even) per video frame, NTSC is a 2: 1 interlace system.
Describes a characteristic of a graphic IMAGE, which enables alternating rows of the image to be displayed in separate passes as it downloads. A fuzzy but complete version of the image thus appears quickly in the browser and gets progressively sharper as the details are filled in.
TV & CRT pictures must constantly be "refreshed". Interlace is to refresh every other line once/refresh cycle. Since only half the information displayed is updated each cycle, interlaced displays are less expensive than "non-interlaced". However, interlaced displays are subject to jitters. The human eye/brain can usually detect displayed images that are completely refreshed at less than 30 times per second.
HDTV is scanned in two different ways, one being progressive and the other being interlaced. Interlaced scanning is when the TV uses two separate passes to make an image on the TV. The first pass will display the odd horizontal lines such as 1, 3, 5, 7 and so on. On the next pass it displays the even lines such as 2, 4, 6, 8 and so on. Since this is done so fast the human eye sees this as being one picture instead of two. After the second pass the third will go back to displaying the odd lines, then even again and so on.
