In recent years, digital camera products have gone through a period of rapid development, from millions to 5 million, 8 million, or even higher. At present, consumer grade digital cameras have been as high as tens of millions of products, but the mainstream products are still hovering around 8 million - 12 million. According to industry analysis, from the point of view of practical application, at present, most users use digital cameras are used to take pictures, and then digital printing. The mainstream of the 5 million - 8 million pixels in social ownership has been basically able to meet the daily needs. In fact, 2 million pixels can reach the resolution of 1600*1200, which can reach the basic requirements of printing. In accordance with the 300dpi standard to calculate, 2 million 100 thousand pixels can produce standard 5 inch photos; 5 million pixels can reach about 2580*1936 resolution, can perfectly output 14 inch photos; 8 million pixels can produce more than 16 inch photos. There are two main types of photoreceptor component market popular digital camera products, one is CMOS (according to the current technical standards to judge should belong to the low-end CMOS), the manufacturing cost is low but the image quality is not good; the other is CCD, than the price of low-end CMOS is high, but in the same pixel value of imaging the effect is better than CMOS. The trend of application of these two kinds of photosensitive components, CMOS photoreceptor component lead into the low-end consumer level digital camera products, CCD photoreceptor component then began to spread and become the mainstream of the market catch up from behind. Because many consumers do not understand the technical development of digital camera, the contact time is late, the mainstream products are exposed to is basically already popular CCD senso
