In image capture and processing, Digital camcorder has a unique advantage. With the popularity of computer image processing techniques for the recognition of computer, digital camcorder is no longer a fashionable thing. And gradually they are into the practical stage.

Shutter: Digital camcorder shutter speed is another important parameter. In the consumer digital camera shutter speed to the fastest OLYMPUS number of C-2500L, and it has a 1 / 10000 second quick stop. Other consumer digital camera’s shutter is mostly in 1 / 1000 seconds. It is basically to meet most of the day to day shooting. Shutter not only depends on the “fast” depends on “slow” is the shutter delay. Such as the C-2020Z with 16 seconds up to the door quickly. It is enough to shoot a night scene but the shutter is too long will increase the digital photos “noise “. That is, the photo will appear mixed stripes. There’s more advanced camera adopted the “B” the shutter, but few, if latest NIKONCP990 a B shutter.
