百万像素手机摄像镜头模块规格（Module specifications for megapixel camera lens） Mega pixel mobile phone camera lens module specifications [duotu] Release date: March 7, 2009 hits: 119 Source: 52RD mobile research and development authors: With the worldwide mobile phone market growing dramatically, the camera lens from the traditional VGA class of 300 thousand pixels to 1 million 300 thousand pixels, showing leaps and bounds technology upgrade growth. Mobile phone image capture module is increased by 4 times the pixel, enhance joint image extraction module in optical lens, image sensor, DSP chip, memory capacity, white light LED and a liquid crystal display panel level, consumers will replace the mobile phone will. Therefore, the pixel level mobile phone taking lens module is a new type of mobile phone product which will lead to the marshal class innovation of mobile phones and new mobile phone products. Therefore, the related specifications and techniques of mobile phones are very important for those who understand the industry. The purpose of this paper is to make a compact and comprehensive introduction to the optical system of mobile image taking lens module, to introduce the basic technology, application and optical simulation concept of mobile image taking lens module. 1 million 300 thousand pixel cell phone taking lens specifications At present, Taiwan photoelectric industry has developed 1 million 300 thousand pixel mobile phone taking lens as soon as possible. Its specifications are shown in Table 1 [note 1]: The image detector 1/4 inch image detector size 3.584 x 2.688 mm 1290 x 966 pixels (1 million 300 thousand) pixel size 2.8 x 2.8 m focal length focusing effective focal length of 4.5 mm images of 4.6 mmMTF modulation transfer function 40% 65% main relative illumination light incident image detector Telcentric Angle Distortion -2% 18 degrees of distortion Table 1 specifications of optical lenses for typical CMOS image sensors In 2003, the lens industry has completed
