All my shots from Canon G12 started to be striped.Like moire.

Il est fort possible que le Canon IXY 500 ne soit pas en mesure de lire correctement la carte m?moire ou que la carte m?moire soit d?fectueuse. Voici quelques ?tapes que vous pouvez suivre pour r?soudre ce probl?me voici ce qu'il y a ? faire :
Veuillez v?rifier que la carte m?moire est ins?r?e correctement dans l'appareil photo. assurez-vous que la carte est bien enclench?e et qu'elle est ins?r?e dans le bon sens.
Ensuite, essayez une autre carte m?moire. Si l'?cran de l'appareil photo fonctionne normalement avec une autre carte m?moire, cela signifie que la carte pr?c?dente est d?fectueuse et doit ?tre restaur?e.
Bien s?r, formatez la carte m?moire. Il est possible que la carte m?moire ait ?t? format?e pour une utilisation avec un autre appareil photo ou un autre p?riph?rique, ce qui peut causer des probl?mes de compatibilit?. Essayez de formater la carte m?moire dans l'appareil photo avant de l'utiliser.
V?rifiez que l'appareil photo est ? jour. Il est possible que l'appareil photo ait besoin d'une mise ? jour du firmware pour prendre en charge la carte m?moire que vous utilisez. V?rifiez le site Web du fabricant pour les mises ? jour du firmware. Je pense que ?a marchera.

you may need to adjust the scene mode by turning the knob to scn you may check out the manual through this link http://chriszaluski.com/com220/docs/Canon%20G12%20Handout.pdf turn to page 3

this camera must be fallen, in such situations the lens motor/gears struck. open it loosen the motor and peripheral parts.

The A530 works with SD cards, 2GB and smaller. It will not work with larger SDHC cards. You need to use SD cards, 2GB and smaller.

The following describes the symptoms, cause and prevention of the Moire effect. Symptoms of the Moire effect When you are shooting a subject that has a fine regular pattern such as stripes or plaids, a ripple that does not exist on the subject sometimes appears in the image. This effect is called the Moire effect. Why does the Moire effect occur? Digital cameras and camcorders are equipped with imaging devices such as CCD sensors and CMOS sensors that have pixels that are finely aligned horizontally and vertically that convert light into electronic signals. When the pixels and the pattern on the subject overlap slightly misaligned, an interference pattern occurs and a ripple that does not exist on the actual subject may appear. This is the Moire effect. Preventing the Moire effect You can reduce this effect by changing the distance, zoom setting or the angle of the image. If you are using a camera with manual focusing, the Moire effect can be reduced by simply changing the focus slightly. Reference You may find another Moire effect displayed on the LCD of the camera. As this is caused by the aligned pixels on the LCD, this effect does not necessarily appear in pictures you have taken.

When you are shooting a subject that has a fine regular pattern such as stripes or plaids, a ripple that does not exist on the subject sometimes appears in the image. An example of this can be seen in the pictures below. The photo on the left shows the fine plaids pattern on the shirt. The photo on the right is a distance shot of the same shirt. In this photo, you can see a ripple that is not visible in the photo on the left. This effect is called the Moire effect. Why does the Moire effect occur? Digital cameras and camcorders are equipped with imaging devices such as CCD sensors and CMOS sensors that have pixels that are finely aligned horizontally and vertically that convert light into electronic signals. When the pixels and the pattern on the subject overlap slightly misaligned, an interference pattern occurs and a ripple that does not exist on the actual subject may appear. This is the Moire effect. Look at the image above. This image shows red cross-stripes and black cross-stripes overlapped slightly misaligned. When you look at the entire image, you find a ripple that differs from either of the patterns. This is the same principle that causes the Moire effect. Preventing the Moire effect You can reduce this effect by changing the distance, zoom setting or the angle of the image. If you are using a camera with manual focusing, the Moire effect can be reduced by simply changing the focus slightly. Reference You may find another Moire effect displayed on the LCD of the camera.

Sometimes odd stripes or colors will appear in a digital image, either from a high-end digital camera, or from a scanned image. This effect is called moir? and is caused when a fine pattern in the subject (such as the weave in a fabric or very close, parallel lines in architecture) matches the pattern of the imaging chip. When two patterns meet, often a third, new pattern is created. This third pattern is called moir?. Notice in the illustration below the round, circular patterns (on the right) created as the two grids are combined; this is moir?. In order to reduce (or eliminate) moir?, a special anti-aliasing filter is mounted in the camera. If too strong a filter is mounted an overall soft image will be produced, but with no moir?. If a weaker filter is chosen the image will be sharper, but there is more of a chance for moir? to happen in some circumstances. Nikon has chosen to produce the sharpest image that can be made, even though there may be some moir? in parts of some images. Notice the red/blue stripes on the bottom of the bag (which should be solid grey) To help reduce moir? there are many techniques to use: Change angle of camera. Since the angle of the camera and subject causes moir?, slightly changing the angle of the camera (by rotating the camera) can remove or change any moire that is present. Change camera position Again, changing the angle relationship by moving left or right, up or down can reduce moir?. Change focus point Moir? is caused by very sharp focus and high detail on fine patterns; slightly changing the focus point changes the sharpness and can help to remove moir?. Change lens focal length Different lenses or focal length settings can be used to alter or remove moir? Remove with software Nikon Capture (as well as several third-party, Adobe® Photoshop® plug-ins) can be used to remove any moir? that does appear in the final image. Of course it may not be possible to remove all moir? in all cases, but in general an overall clean, sharp image with slight moir? is preferred over a soft focus image. Moir? can happen with images from all digital cameras and scanners, but is more likely to happen with an SLR-type digital camera system because the lens, sensor and software are designed to produce the sharpest, most accurate image possible. When reviewing images to see if moir? is present be sure to be looking at the image on the computer screen (or the camera's LCD) at the full, 100% view. If you zoom out on-screen a false moir? can be produced by the pattern of the monitor grill.
