Image Acquisition and Techniques to Perform Image Acquisition

Abstract

In the present scenario images have become the most suitable way to keep our past alive. Nowadays people are very busy in earning their livelihood and day to day life, even though they want to keep their golden moment alive for the rest of life. Images have touched almost all the fields like medical, sports, social networking and many more. It is the need of time to know how the images are being captured and stored into memory. To deal with images and before analyzing them the most important thing is to capture the image. This is called as Image Acquisition. Image Acquisition is achieved by suitable camera. We use different cameras for different application. If we need an X-Ray image, we use a camera (film) which is sensitive to XRays. If we want Infra Red image, we use cameras which are sensitive to Infra Red radiations. For normal images (family pictures etc.) we use cameras which are sensitive to visual spectrum.
