Ever since the invention of the first camera obscura and the advent of photography in the 19th century, scientists have been fascinated by the use of light sensors to capture the world around us from the perspective of a man-made machine. Most recently, all eyes have been on image sensors relying on CCD or CMOS technology. These state-of-the-art camera devices can convert optical images into an electronic signal, and are used in applications for sectors including healthcare, automotive, media or security.
