Moiré
By Vincent Bockaert
If a scene contains areas with repetitive detail which exceeds the resolution of the camera (1), a wavy moiré pattern (2) can appear, as shown in crop A.
Moiré patterns are often an undesired artifact of images produced by various digital imaging and computer graphics techniques, for example when scanning a halftone picture or ray tracing a checkered plane.
Moiré pattern - the colourful wavy pattern that appears on an image because the detail on the subject matter exceeds the resolution of the camera. You also used to see it on TV presenters when they wore fine checked ties or suit jackets.
Moiré
Moiré is a pattern visible in digital images, usually waves that appear when the repetitive nature of a detail exceeds the resolution of the camera's ability to differentiate the distinctive details in the actual subject.

Moiré An interference pattern created when a repeating pattern in the subject is overlaid on the image sensor grid. In Nikon D-SLRs, moiré is greatly reduced by means of advanced image processing algorithms and optical low-pass filters.
moiré
An undesirable pattern that appears when a graphic image is displayed or printed with an inappropriate resolution.
moiré
an undesirable optical pattern that occurs when one regular set of parallel lines or dots crosses another set, at various angles of intersection or by the regular pattern of mesh threads intersecting the halftone screen pattern.
Moiré. A visible pattern that occurs when one or more halftone screens are mis-registered in a colour image. Often produces a coloured checkerboard (or rainbow) pattern.

Moiré
An interference pattern which may occur when scanning images with a halftone screen. An example of aliasing error.

Moiré
An interference pattern brought about when images of differing resolution are superimposed. This problem may occur, for example, if small diamond shapes are to be reproduced on a television screen.
Moiré pattern
An undesirable screen pattern in colour printing that results from screen angles of overprinting halftone. Moiré usually results when you scan a halftone or when you scan images taken directly from magazines.
Moiré Effect
The moiré effect (pronounce 'Moa-ray') is an unintended pattern which appears when a regular pattern of grids or lines interferes with another regular pattern placed over it.
Moiré
Patterns formed in portions of a photographic image as a result of confusion between a pattern within the photographic scene and the pattern of pixels within the sensor.
Moiré is the unwanted addition of patterns on a print or scan. These patterns are usually caused when two similar repetitive grids are placed on top of one another

One problem related to digital cameras that merits serious consideration is moiré effect. Moiré is caused by repeating lines or patterns in the image composition that are at a certain frequency to the camera sensor's resolving power.
0, on the other hand, utilizes a unique Autoscan feature that analyzes the image to identify edges and problem areas, such as areas that could produce moiré patterns, halos or other artifacts.
The moiré issues in the scan marked "perfection" are artifacts of Photoshop's resampling algorithms. Note also how tough is it for Photoshop to resample my scan smoothly as the lines become as fine as a pixel. This is a tough target in digital! ...
Note the appearance of moiré in all four bottom squares, in addition to the third square of the first photo (subtle). Both maze-like and color artifacts can be seen in the third square of the downsized version.
This is an optical filter (also known as low-pass filter) placed on the sensor to create a slight blur or softening that helps counteract aliasing or moiré interference.
With the introduction of this ability (along with the option to change Moiré, Noise and Sharpness for
