Sony gives details of double-layered microlenses
Sony has detailed the double-layer microlens technology it used to maintain imaging performance in its chip featuring the industry's smallest pixel size. Its latest Semiconductor and Components online newsletter explains the structure of the ICX681SQW 14.2 MP 1/2.3" type CCD sensor that adds convex lenses beneath the existing microlenses to improve optical condensing (the process of directing more light onto the photodiode). The chip is used in the Cybershot H55 and several recent W Series compacts. The newsletter also gives details of the company's 3:2 aspect ratio, 1.03 million dot LED-lit LCD panel that sounds a lot like the one used in Canon's Rebel T2i.
