One, sensitive implement

This can be to absorb the heart share that resembles a head, important cannot again important. Photograph commonly can divide like the head it is two kinds, it is CCD(Charge Coupled Device) , only a bit more high-grade photograph ability resembling a head to use this kind of sensitization implement, it has sensitivity tall, fight shake, volume is minor wait for an advantage, but price side is opposite also taller; 2 it is CMOS(Complementary Metal Oxide Semiconductor) , it has the characteristic of low power comsumption, low cost, but resolution, the respect such as dynamic limits and noise is goodish. As a whole CCD is become want prep above CMOS like level and quality. When we recommend high-end user to buy, should consider to use CCD sensitization above all implement product, of course, you need price respect to be paid more a bit.

2, resemble element
