The question begs another one or two before an answer can be given :- How is the digital image being viewed? - several possibilities exist :- 1)On the camera LCD display 2)On a computer monitor 3)On a TV set 4)As a print and if so printed by inkjet or laser printer 5)Some other mechanism - eg a standalone viewer into which the camera memory card is inserted Is the whole of the image being displayed or a "cropped" version ie only a part of the whole frame? Is the effect apparent in all tones of the picture or, say, only in the shadow/highlight areas?

Either the quality of the camera itself or the compression method used to transfer data.

When you push the shutter, all pixels of the camera become active and begin absorbing light while the shutter is open. This allows for high quality and non-grainy pictures. The live preview shown on cameras is only a very low quality preview for a small screen so you know what you are pointing the camera at.

It depends on which camera you use.If you have a netbook,the camera that is in the computer takes rather grainy photos.Apple computers have a program called Photo Booth that takes sharp,low resolution pictures.There are also separate cameras called webcams that are separately attached to the computer.Some have 5 megapixels and more and take sharper pictures.

In digital photography, there are a number of features that are thrown into consumer-grade cameras as "selling points." These selling points add no value to the camera, but appear impressive. One of these features is digital zoom. Some cameras may boast an 800X digital zoom. However, the image at 800X is so grainy and indecipherable that you won't be able to make out what it is anyway. It's important to remember that the only important zoom is optical zoom. If you do end up using digital zoom, make sure to only go barely beyond the range of the optical zoom.

If your ipad 2 is grainy or blurry you might want to try using it in the sun, its clearer.Still, for a device that costs a minimum of $500, it would be nice to have a better image sensor, rather than these bottom-of-the-barrel ones Apple insists on using.

Digital camera video features are great for small display or webcams. They do not hold the regular camcorder capacity. Same issue with cell phones but x2. Cell phones are even smaller so you will be dealing with grainy resolution and sketchy sound quality if you want to use it in bigger picture. Basically for blog, fun, webcam, short videos, small projects, etc. You can get away with using just a digital camera or cell phone but for things such as family vacations to corporate advertisements; you would want something more advanced. Not mentioned but memory capacity is really small in cell phones/digital cameras. You can only film a few minutes at most. Your digital camera and cell phone only have limited space and very short recording time. So it would depend on how much you want to record @ a time. I have all 3 & with the cell you can get something spontaneously, but if you go on vacation or have a certain event you plan to attend and want to capture the most of it I wouldnt do it with o

If you use an optical zoom, you can take pictures without getting really close to things. An optical zoom is better than a digital zoom, because an optical zoom does not cause pictures to be pixely or grainy, and digital zooms often do.

less than a drop of water in the chocolate to be grainy.

A megapixel is one million pixels. A pixel is a picture element. Like graphics displayed on a television or computer monitor, digital photos are made from millions of tiny colored dots, or pixels. The more pixels used to produce a photo, the less "grainy" it will appear and the better any enlargements made from it will be. A 6-megapixel camera can produce standard 4 x 6 photos at a remarkable 500 pixels per inch and 8 x 10 photos at 273 ppi. A megapixel (MP) is 1 million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.

Great question. However, you really can't have one without the other. High zoom without the picture density will leave you with grainy pictures. On the other hand, high megapixels though a good zoom will leave you with good macro pictures, anything else will require software manipulation. In the end- you have to determine what your use will be, and buy accordingly.

becaise when you are doing curls your muscsles are not use to the position so your muscles will have to ajust in order for your muscles to get bigger, and they feel grainy because when your doing the curl, the "grainy" will be your tissue muscle

Yeah, it's pretty lame. The photos that are produced by the 1.3 megapixel camera are pretty grainy, but it gets the job done, and that's what the LG Rumor is all about. The video, however, is not bad. It comes with an Image Enhancer, which allows you to touch up an image in a paused video.

yes because its grainy

A digital camera takes the light emitted from the photo subject, and focuses it into the image sensor within the camera. Instead of photographic film, a digital camera has a light-sensing grid called a CCD or CMOS, which can record light as binary data that represents the brightness and the color frequencies. It records the data for millions of individual points, called pixels, which can be put together to recreate the original image. This is the same technology used in almost all computer images.Using Digital CamerasLet's say you want to take a picture and e-mail it to a friend. To do this, you need the image to be represented in the language that computers recognize -bits and bytes. Essentially, a digital image is just a long string of 1s and 0s that represent all the tiny colored dots -- or pixels -- that collectively make up the image.At its most basic level, this is all there is to a digital camera. Just like a conventional camera, it has a series of lenses that focus light to create an image of a scene. But instead of focusing this light onto a piece of film, it focuses it onto a semiconductor device that records light electronically. A computer then breaks this electronic information down into digital data. A digital camera has a sensor that converts light into electrical charges.The image sensor employed by most digital cameras is a charge coupled device (CCD). Some cameras use complementary metal oxide semiconductor (CMOS) technology instead. Both CCD and CMOS image sensors convert light into electrons. A simplified way to think about these sensors is to think of a 2-D array of thousands or millions of tiny solar cells.Once the sensor converts the light into electrons, it reads the value (accumulated charge) of each cell in the image. This is where the differences between the two main sensor types kick in:A CCD transports the charge across the chip and reads it at one corner of the array. An analog-to-digital converter (ADC) then turns each pixel's value into a digital value by measuring the amount of charge at each photo site and converting that measurement to binary form.CMOS devices use several transistors at each pixel to amplify and move the charge using more traditional wires. The CMOS signal is digital, so it needs no ADC. .The amount of detail that the camera can capture is called the resolution, and it is measured in millions of pixels (megapixels). The more pixels a camera has the more detail it can capture and the larger pictures can be without becoming blurry or "grainy."

HDTV is hi definition tv , which is a digital signal with very good clarity. regular tv is analog signal, is more grainy with less detail and is more prone to static or interference.

constipation leads to loose grainy stool passing around a hard plug of stool. So constipation and encopresis.

Grainy rocks not only absorbs water better than crystal rocks, but it filters the water as well.

Pros of digital camerasdigital images can be seen immediately after taking the picture through the small monitor on the back of a cameradigital film (cards, storage devices) can be re-used almost indefinitely, so you do not have to continually buy more cards to take more picturesdigital cameras can handle a wider range of lighting conditions than film handlesdigital cards can generally hold more images than a roll of filmdigital information does not decay with time and does not degrade when copieddigital images do not require processing for viewingdigital images can easily be manipulated on a computer without being scanned firstdigital images can be mailed and shared with others who live far away through image sharing web sitesnewer digital cameras offer more features for the same price, or cost less for the same features than older digital camerasdigital "film" (cards) can be changed in broad daylightCons of digital camerasdigital cameras require electricity to operatedigital cameras can be more expensive than film camerasall digital cameras quickly become obsolete or outdatedthe digital camera you buy today can become outdated within 12 monthswhen you buy a better digital camera, you often have to upgrade digital cards and the computer you store your files on, which can be expensivedigital cameras create files that are relatively largehi-resolution digital images have very high file sizes, requiring large digital storage devicesdigital cameras require special storage cards to hold digital image filesdigital camera files must be downloaded to a computer and most computers are not inexpensivesome digital storage devices are subject to failure, causing a loss of stored imagessome people prefer to print digital images on paper, which requires a printer, ink and paper, all of which can become expensivetaking pictures in low-light conditions results in digital noise that can be difficult, or impossible to get rid ofdigital cameras with removable lenses can get dust on the sensor, resulting in a spot on every image taken with that camera -
