Reflecting imaging - Essay Example Cameras form the central part in understanding the image formation processes. The analogue forms the start of modern imagery with components remaining the same over the years. The principle of using reflected light from the object still forms the integral part in image formation. Some cameras such as those used at night in infrared radiation detection are one of the few types that do not use the same principle of reflection target object. Significant similarity between human eyes and digital cameras is very clear. Capturing, storage and display of the images has improved overtime with current images store in data form and displayed on the camera.in the article, an explanation of digitisation and the processes involved such as quantisation and sampling has remained elaborated. The article further explains terms and problems associated with this digitisation. Imaging is a form of visual representation of an object or reproduction of the same visual object. Reflection is the property of waves changing direction by bouncing off the surface of object as they cannot pass through or get absorbed. The bouncing of light is the most common and it is important in image formation even to human eyes. Reflected light imaging is the process of forming images when electro-optical waves bounce from the target to the camera or recording device. However, transmission imaging involves waves passing through the object before reaching the camera or recording device. In this imaging technique, the images produced depend on the absorption and reflective properties of the object at the specific wavelength of the incident light. Classification of images leads to an image being a digital or analogue image based their properties. Digital image relates to visual illustration of an object in an electronic form that can remains manipulated and stored by electronic devices, which are 2D image I[r, c]. These kinds of images are tangible but have
