Why dv beat out the image is fuzzy

Dv yesterday did not previously been used by a computer, but beat out the very point of view I do not know yet clear why the photo camera?
This is a dv parameters / 42/41333/param.shtml

Viewfinder 0.3 inches, color liquid crystal display (approximately 113,000 pixels)
this …it is too low pixel digital cameras are at least 400 Ah million 1/3.4 inch CCD
CCD imaging is the key to ordinary digital camera at least 1/2.5 of the CCD, which focused on DV-shot, and it should not every frame of the image is very clear, the basic 1 second Need 24 images, DV images are clear, it said DV every 1 second of video shot on at least 1M * 24 = 24M size of the store, which is clearly impossible, so not sure DV camera make it clear that if Your film is, so clear images Geng Shibi DV, the film definitely better than digital
there is a clear set of DV, you can set the video resolution, if you set too low, making the technology does not like how , Then I am sorry, make sure it's not up to much of

the whole video is stored in order to ensure speed and recording speed, can not substantially improve the quality of the image, which is why the players when they beat DV images Not as clear photos and images is not a lot of reasons, as if to make it clear, it will greatly increase the storage space required for storage and memory speed, which in the current digital standard DV technology, the basic reality of it is not at all, Of course, you can buy those high-definition video to the DV, which will be relatively good point
