Interlaced scanning
| CCTV glossary (глоссарий терминов по видеонаблюдению) |
- A scanning process for reducing image flicker in which the distance from center to center of successively scanned lines is two or more times the nominal line width, and in which the adjacent lines belong to different fields.
- A technique of combining two television fields in order to produce a full
- Scanning method in which half of the lines are scanned in one field (odd-numbered lines), and the other half are scanned in the next field (even-numbered lines). thus adjacent lines of a complete picture (one frame) belong to successive fields. doubles the screen refresh rate as seen by the viewer and reduces flicker. at screen refresh rates significantly higher than the 25/30 frames/second used in tv systems, interlaced scanning may not be necessary.
- A technique of combining two television fields in order to produce a full frame. the two fields are composed of only odd and only even lines, which are displayed one after the other but with the physical position of all the lines interleaving each other, hence interlace. this type of television picture creation was proposed in the early days of television to have a minimum amount of information yet achieve flickerless motion.
- Process whereby the picture appearing on a video screen is divided into two parts. interlaced scanning reduces flicker by increasing the electron beam’s downward rate of travel so that every other line is sent. when the bottom is reached, the beam is returned to the top and the alternate lines are sent. the odd and even line scans are each transmitted at 1/60 s, totaling 1/30 s per frame and retaining the standard rate of 30 frames per second. the eye’s persistence of vision allows the odd and even lines to appear as a single image without flicker. international annealed copper standard (iacs): conductivity measurement system in which the conductivity of annealed, unalloyed copper is arbitrarily rated at 100 percent and in which the conductivities of other materials are expressed as percentages of this standard.

Interlace, английский
To display a video frame in two fields. one field contains the even lines of the frame, the other field contains the odd lines. during playback, the lines in one field are displayed first, then the lines in the second field are displayed.
Interlace line, английский

Interlaced, английский
- Чересстрочная развертка. термин, означающий чересстрочную развертку у мониторов. луч электронной трубки проходит сначала по нечетным строкам, а затем по четным или наоборот. т.е. для получения изображения экран сканируется дважды. приводит к худшему качес
- 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.
- This is the term used to describe an image sensor that gathers its data by first processing the odd lines, and then processing the even lines.

- A picture in gif format that is gradually displayed in a web browser, showing increasingly detailed versions of the picture until the entire file has finished downloading.
Interlaced scan, английский
Interlaced video is a commonly used video capture technique in which the imagery consists of two fields of data captured a frame apart and played back in a manner that reproduces motion in a natural, flicker-free form. interlaced video takes up less storage capacity than progressively captured video.
Interlaced storage, английский
Запоминание в несмежных равноотстоящих областях
Interlaced video, английский
- Process of scanning video frames in two passes, with each pass painting every other line of the frame onto the screen. ntsc`s 525-line frame scans in two fields of 262.5 lines each that take 1/60 second to paint; a frame takes 1/30 second to paint. noninterlaced video scans complete video frames in one pass usually producing a higher image quality.
- Чересстрочное видео; видеоизображение, создаваемое с помощью чересстрочной развертки
- The traditional television system of display in which separate fields of odd-numbered scan lines and even-numbered lines are interlaced between each other.

An amplifier with input circuitry and output circuitry designed to eliminate the effects of changes made at either upon the other.
Incident light, английский
- The light that falls directly on an object.
- A ray of light that falls on the surface of a lens or any other object. the "angle of incidence" is the angle made by the ray with a perpendicular (normal) to the surface.
- The light that "makes it to the scene" after roughly 82% of it is absorbed and scattered.
- Light that shines onto the face of a solar cell or module.
