Design of 8 mega-pixel mobile phone camera

  • The high-pixel mobile phone camera is demanded with the development of mobile phone market. An 8 mega-pixel lens system with large relative aperture and large field of view (FOV) is designed with Zemax. The system includes one glass aspheric lens, three plastic aspheric lenses, an IR cut filter and a sensor cover glass. The F-number is 2.45 and FOV is 68,the effective focal length and back focal length are 4.25 mm and 0.5 mm respectively. The sensor MT9E013 have 8 mega pixels which is made by APTINA, the maximum resolution is 3264 x 2448 and the minimum pixel is 1.4 m.The design result shows that RMS spot radius at different fields are less than 1.4 m,the MTF value is more than 0.5 in most fields of view at 1/2 Nyquist sampling frequency. Distortion is less than 2%, and TV distortion is less than 0.3%.
