Document Type and Number:
WIPO Patent Application WO/2010/011070
Kind Code:
A2
Abstract:
The present invention relates to a wide-angle lens system and an electronic device including the same, and comprises first, second and third lenses that are sequentially installed behind an iris. Therefore, the invention uses the three lenses to rectify distortion problems occurring in a conventional wide-angle lens system having a view angle of 70° or more. In addition, as a result of the miniaturized and distortion-free configuration, the invention may be not only installed and used in an electronic device such as a mobile phone, but also utilized for digital zoom operations.
