moire
adj 1: (of silk fabric) having a wavelike pattern [synonym: {moire},
{watered}]
n 1: silk fabric with a wavy surface pattern [synonym: {moire},
{watered-silk}]

Moire \Moire\ (mw[aum]r), n. [F. Cf. {Mohair}.]
1. Originally, a fine textile fabric made of the hair of an
Asiatic goat; afterwards, any textile fabric to which a
watered appearance is given in the process of calendering.
[1913 Webster]

2. A watered, clouded, or frosted appearance produced upon
either textile fabrics or metallic surfaces; moi`r['e].
[1913 Webster]


Moir'e \Moi`r['e]"\ (mw[aum]`r[=a]"; m[=o]"r[=a]), n.
1. A watered, clouded, or frosted appearance on textile
fabrics or metallic surfaces.
[Webster 1913 Suppl.]

2. Erroneously, moire, the fabric.
[Webster 1913 Suppl.]

3. A wavy pattern of lines produced by the superposition of
two patterns having closely spaced, often curved, lines,
so that the lines of the two patterns intersect at an
acute angle. When the superposing patterns are moved
relative to the observer or relative to each other, a
shimmering effect is produced in which the apparent
pattern changes, often producing a pleasing artistic
effect. The effect may be seen, for example, when the
superposed folds of a sheer fabric, such as a window
curtain, are observed with transmitted light.

Syn: moire pattern.
[PJC]

4. (Printing) An interference pattern produced by the dots of
a color printing process.
[PJC]

{Moire antique}, a superior kind of thick moire.
[1913 Webster]


Moir'e \Moi`r['e]"\, a. [F., p.p. of moirer to water (silk,
etc.). See {Moire}.]
Watered; having a watered or clouded appearance; -- as of
silk or metals.
[Webster 1913 Suppl.]


Moir'e \Moi*r['e]"\, v. t. [imp. & p. p. {Moir['e]ed}; p. pr. &
vb. n. {Moir['e]eing}.] Also Moire \Moire\ [F. moir['e].]
To give a watered or clouded appearance to (a surface).
[Webster 1913 Suppl.]

  • What is moiré? How can we avoid it? - Photography Stack Exchange
    What is the image defect called "moiré"? What causes it, and how can we avoid or reduce it? Is it related to "false color"?
  • astrophotography - What causes and how can I avoid this moiré pattern . . .
    The moire like pattern only becomes apparent on flattening the image I tried another series of images that were taken facing south and didn't get the strange effect
  • post processing - Is it possible to eliminate Moiré patterns from . . .
    The Moiré pattern you see is an artifact of the sampling frequency of the camera relative to that of the photographed display If the camera sensor's resolution isn't somewhat close to that of the projected image of the display, you won't see any Moiré, or the pattern you do see will be comparable in size to the screen itself One simple way to avoid this problem is to photograph the display
  • How To Reliably Trigger Moire? - Photography Stack Exchange
    The patterns from work best and print themselves without moire more easily than the test patterns from the — either or The concentric-circle patten in particular should be very effective, as it has decreasing distance between each circle making it almost guaranteed to interfere with your camera's sensor-pixel grid
  • does the presence of Moiré in a photo implies the lens outresolve the . . .
    As to your question about producing moire patterns when the sensor has higher resolution (resolvable line pairs) than the lens: I'm skeptical that that's possible, since an optically blurred image can't be sharpened by using more pixels You'll just get a better final image print of the blur itself
  • image quality - Photography Stack Exchange
    Aliasing- When the size of a detail (pattern) records the same size (or smaller) than the size of the pixels you can get false interference patterns (moire) This is combated by using an anti aliasing (AA) filter, which slightly blurs details and reduces sharpness
  • moire - Is there a name for artifacts for taking a photo of LCD LED . . .
    The effect is called Moire It is caused by the grid pattern of the photosites in your sensor and the grid of pixels in the screen interacting It happens when the grids do not exactly line up It can occur with any gird or parallel lines It is explanined in more depth here To reduce this effect try to reduce how much of line the screen is to the sensor
  • Why do photos of digital screens turn out the way they do?
    3 As other answers state, the effect is called Moire But why does it happen when you downscale or zoom-out? As prevoiusly stated Moire happens when two patterns interact, specially if the two patterns have a "frequency" (read size of the repeating characteristic) close enough to each other
  • image processing - Photography Stack Exchange
    Moire patterns caused by sampling a continuous image are aliases The same math applies to them just as it applies to high frequencies aliasing into a audio stream and sounding like background whistles It's the same stuff, with the same theory to explain it, and the same solution to deal with it
  • artifacts - What caused this pattern of lines (moire?) in this picture . . .
    What caused this pattern of lines (moire?) in this picture I scanned from a book? Ask Question Asked 10 years, 4 months ago Modified 10 years, 4 months ago
