The development trend of CMOS image sensor

As sensor and the sensor, which is the core of the rearview camera, is also the key technology. There are two main types, one is CCD (or electric charge) element; The other is a CMOS (complementary metal oxide conductor) devices.

CCD is used in photographic camera's high-end technology components, CMOS is used in the lower image quality of products, it has the advantage of manufacturing cost is CCD is lower and lower power consumption, this is also the market a lot of using USB interface without external power supply products and cheaper prices.

Although technically quite different, the relevant professionals think CCD and CMOS performance gap is not very big, both of the light source is CMOS camera some higher requirements, but now has been basically solved the problem. After recent years of development, a CMO sensor on the wafer technology and imaging technology has made great progress. Among them, the imaging technology of wafer from the early 3 t, 4 t, 5 t, 6 t and 7 t, 8 t until the latest technology, the CMOS imaging technology gradually mature application, the application of this technique to a great extent, avoid the disadvantage of CMOS, and the advantages and obtained the very big enhancement.

In addition, CMOSSensor technology also has obtained the very good adaptability in industry applications, such as ITS high-speed capture/security, Anti - Blooming, Anti - Smear, etc.). And CMOSSensor semiconductor technology makes the low cost and high resolution, imaging effect of the big picture.

Forecast according to the relevant institutions, CMOS image sensor will grow by 8% in 2012, to $6.3 billion, and the configuration of the camera mobile devices, such as touchscreen smartphones, tablets, and automobiles, medical equipment, and safety of network equipment such as embedded digital image application of a new wave of traction, the CMOS image sensor market in 2016 is expected to increase year after year, will be up to $10.88 billion, five years from 2011 to 2016 average annual growth rate as high as 13.4%, compared with 5% of the 2006 ~ 2011.

As the video surveillance industry towards high quality, high to the requirement of image frame rate, high dynamic and low intensity of illumination direction, with CCD sensor as the carrier of high-definition cameras under cost pressure, such as resolution are hard to break through the above technical bottlenecks, make the development of CMOS sensor technology to fill the space, which is more and more become the security industry hd video image, the mainstream of high imaging speed application image sensor technology.
