anti-shake?

Question

What is the anti-shake feature in a digital camera??

Answer 1

Morey0000's description is spot on for true anti-shake technology. And if you're looking for true digital anti-shake in a digital camera this is a good explanation.

Realizing that "anti-shake" is a buzz-word in the market these days there are a number of companies that are marketing (falsely in my opinion) "shake-reduction" technology that is supposed to remove the bluriness associated with hand-holding a camera.

They accomplish this by adjusting the ISO speed in the camera which in effect allows you to speed up the shutter speed, which in turn should reduce the bluriness of the shakes (remember the higher the shutter speed the less it is prone to camera shakes).

The problem is that by raising the ISO you also introduce graininess in your picture (often referred to as noise). This graininess significantly decreases the sharpness and contrast of your shots. It's a cheap way of marketing shake reduction at the expense of picture quality.

Do you homework before you buy. If the camera has true shake reduction as Morey outlined, you're better off than any trickery of raising the ISO will get you.

You know how hard it is to get a good picture when you are zoomed in all the way or when you are in the car on a bumpy road?
Well the anti-shake feature on a digital camera attempts to counter-act an unsteady hand. It does this in two ways...by slightly moving the lens so that it counter-acts the movement and by adjusting the sensor that captures the image.
It works pretty well most of the time, but it won't fix everything. Have fun taking pictures.

Answer 3

You know how you will be filming something you think you are holding still and then when you watch it back it is actually shakey because your hand got tired or something?

Anti-Shake takes care of that and stablizes the camera's focus so that even if your hands are slightly shakey it comes out perfect every time.

This doesn't mean you can shake the camera on purpose, but if you are trying to hold it still, the camera will compensate for those small shakes. It's awesome!

The anti-shake feature means that you can take a picture and it will be clear (good resolution) regardless of whether you are moving or not. You can take a picture from the window of your car, you can take a picture on a boat, you can even take a picture when slightly *happy*...it's a better version of the Sport feature-- that allows you to take clear pictures of other objects in motion. If you have an anti-shake feature and a Sport feature, you can be guaranteed non-blurry photos.

Answer 5

It moves either an optical element or the ccd (sensor) to compensate for the small hand shaking when you take a photo. Most of the good systems will buy you 2-3 stops of additional 'hand-hold' ability.

This means that instead of needed, let's say 1/80 sec to keep the image sharp. With AS (or IS), you'll be able to hand hold with shutter speeds 2 to 3 times lower, or 1/40 to 1/20 sec. Great for low light situations (where the subject isn't moving).

Answer 6

i'm not a camera junkie, but that's an easy question. anti-shake is an automatic feature on some cameras that will compensate for the shaking that some peoples hands are apt to do. ( even if they don't know it) it would be like, placing your elbows on your knees while steadying yourself as you take a picture.

Answer 7

When you zoom in really close, even the smallest movements of your hand can look really crazy in the camera. That feature helps the camera focus and reduces the visible shaking.

Answer 8

Pretty sure it's for for the picture-taker. If their hand is shaking while they take it, it will help keep the quality of the photo.

Answer 9

You cant take a picture and be drinking a chocolate shake at the same time. It freezes the picture too much.

Answer 10
