Aberratio, латинский
Aberratio criminus, латинский
Aberratio ictus, латинский
Fehlgehen der tat: der täter trifft statt des anvisierten opfers oder tatobjekts ein anderes=versuch am anvisierten in tateinheit mit fahrlässigkeit am getroffenen opfer/tatobjekt. nicht zu verwechseln mit "error in persona".
Aberratio [onis, f], латинский
Aberration, английский
- A term from optics that refers to anything affecting the fidelity of the image in regards
- A term from optics that refers to anything affecting the fidelity of the image in regards to the original scene.
- A distortion of image quality or color rendition in a photographic image caused by optical limitations of the lens used for image capture. aberrations commonly show up in the form of halation around high-contrast portions of the image, or “smearing” of color toward the edges of the frame. aspheric lens surfaces and advanced lens coatings are often used in more expensive or complex lenses as a means of reducing aberrations. for more on this subject, see the explora article, “optical anomalies and lens corrections explained.”
- Any flaw introduced during the manufacturing or grinding of a spectacle lens that can result in image blur. it may be inherent in the lens design or may result from an error in processing.
- An action or growth which is not usual or expected
- An apparent change of place, or alteration of their mean position, in the fixed stars, caused by the earth`s orbital movement.— aberration of a planet signifies its progressive geocentric motion, or the space through which it appears to move, as seen from the earth, during the time which light occupies in passing from the planet to us.—crown of aberration is a spurious circle surrounding the proper disc of the sun.—constant of aberration, or amount of displacement in the sun`s longitude, arising from
- In celestial navigation, the apparent displacement of a heavenly body due to the observer’s motion.
Aberration (аберрация), английский
Термин из оптики, который обозначает все эффекты, влияющие на точность воспроизведения изображения относительно исходной сцены.
Aberration from standard, английский
Aberration-free system, английский
Chromatic, английский
- Having to do with color, or wavelength.
- Relating to or produced by color.
Chromatic aberration, английский
- Optical term, which refers to the distortion of an image as a result of a scattered focal point caused by a defect in a lens. a combination of lens can be used to correct this effect.
- Chromatic aberration. failure of a lens to focus all colours at the same point. the aberrations can be along the optical axis (longitudinal ca, or loca) or off-axis (lateral or transverse ca, tca).
- An optical defect of a lens which causes different colors or wave lengths of light to be focused at different distances from the lens. it is seen as color fringes or halos along edges and around every point in the image.
- Also known as the purple fringe effect. it is common in two megapixel and higher resolution digital cameras (especially those with long telephoto zoom lenses) when a dark area is surrounded by a highlight. along the edge between dark and light you will see a line or two of purple or violet colored pixels that shouldn`t be there.
- Also known as color fringing, chromatic aberration occurs when the collective color wavelengths of an image fail to focus on a common plane. the results of chromatic aberration are most noticeable around the edges of high-contrast images, especially toward the edges of the frame. chromatic aberration is most common on less expensive lenses, although even the best optics can occasionally display lower levels of chromatic aberration, under certain conditions.
- In terms of lens optics it is the failure of the lens to focus all colours (rgb) at the same point. it shows up as colour fringes in areas of the image where dark meet light (think edge of a building against the sky). it is more common in wide angle lenses, and those of inferior optics (kit lenses). it is correctable, to some degree, using photoshop, lightroom or software of your choice.
- Also known as purple fringing. it is fairly common in 2mp digital cameras and above, especially if they have long telephoto lenses. you can see it when a dark area is surrounded by a highlight. in between the dark and light, you may see a band of purple pixels that shouldn’t be there. there are ways of removing this which i have covered in the photoshop section.
- When a lens causes white light to be broken into various component colors with each focus at a different distance from the lens, commonly producing color fringe around a viewed image.
Chromatic aberration., английский
Longitudinal (axial)
Chromatic aberrations, английский
Image distortions caused by wavelength-dependent optical effects
Chromatic adaptation, английский
The eye`s ability to compensate, after a few minutes, for variations - sometimes drastic ones - in the color of light sources so that everything appears normal. tip: since the film doesn`t compensate, you may want to use a color-temperature meter.
Chromatic color, английский
Chromatic dispersion, английский
- Расширение светового импульса, вызванное разницей скоростей распространения волн различной длины, составляющих данный импульс (см. также коэффициент преломления)
- The frequency dependence of the phase velocity in a transparent medium
- Wavelength-dependent pulse spreading in optical fibers, measured in pico seconds (of pulse spreading) per nanometer (of source bandwidth) per kilometer (of fiber length). it is the sum of waveguide and material dispersion. reduced fiber bandwidth caused by different wavelengths of light traveling at different speeds down the optical fiber. chromatic dispersion occurs because the speed at which an optical pulse travels depends on its wavelength, a property inherent to all optical fiber. may be caused by material dispersion, waveguide dispersion, and profile dispersion.
- Хроматическая дисперсия
Chromatic dispersion (cd), английский
The variation in the velocity of light (group velocity) as a function of wavelength. it causes pulses of a modulated laser source to broaden when traveling within the fiber, up to a point where pulses overlap and bit error rate increases
Chromatic dispersion coefficient, английский
Chromatic gray, английский
Grays that exhibit a subtle, but discernible hue.
Chromatic simultaneous contrast, английский
Simultaneous contrast concerning color changes that occur due to the influence of the surrounding colors
Chromatic аberration, английский
Transverse, английский
- Across. a transverse section is a section across the length of a building or room.
- Поперечный
- Directions in wood at right angles to the wood fibers
- Perpendicular to the keel (athwartship).
- Across the vessel; athwartships. trim - fore and aft balance of a boat.
- Literally, “across,” usually signifying a direction or plane perpendicular to the direction of working.
