Major techniques Involved
- Optical. It is defined as a method used in a still or a video camera for stabilizing the recorded image by changing the optical path to the sensor. The fact that the optical stabilization systems stabilize the image projected on the sensor before the sensor transforms the same into digital information forms one of their basic elements.
- Digital. Real-time digital image technique is mainly used for video cameras. This popular technique helps in shifting the electronic image from frame to frame of video, enough to neutralize the motion. It employs the pixels for providing a buffer for the motion. This technique minimizes disturbing vibrations from videos and enhances still image quality by enabling a person to increase the exposure time without affecting the image quality. This technique hardly influences the noise level of the image.
- Stabilization filters. Most of the video non-linear editing systems make use of stabilization filters capable of correcting a non-stabilized image by keeping a track of the movement of pixels in the image and correcting the image by moving the frame.
Advantages of the technique
Blurry images are a major problem faced by a majority of photographers both amateurs and experienced ones. Blurriness usually arises by hand movements while capturing images. The problem is more common when a person uses digital cameras with slow shutter speeds or longer focal lengths.
This IS technique enables photographers to take excellent pictures under lighting conditions that once upon a time were considered too risky for capturing clear and sharp still images. The technique helps in capturing sharp pictures at shutter speeds three, four or five times less than the normal. With the introduction of this feature, amateur and experienced photographers would not have to worry about blurred images even while shooting in poor lighting conditions.
Always keep in mind that the IS feature also consumes power. Turning it on for a longer time drains the battery. It is advisable to switch it on only when required.
These are some of the prominent facts about the technique one must be aware of. A detailed understanding of the feature will help you know your device properly. Almost all the advanced digital cameras hitting the market come equipped with this feature today. You can consider buying the image-stabilized devices via an online electronic store these days. In addition to these devices, you can also consider buying the new camera lenses from these stores.
