In conventional cameras, both analogue and digital, they all make use of an interlace scan system. This system works on a two scan process. That is, the CCD is scanned twice in order to make one frame. Unfortunately only half of the available lines on the CCD chip are scanned each time for Jewelry Photography Los Angeles.
The first scan, for example, will scan line 1,3,5, etc. Then the second run will scan line 2,4,6….etc. These two separate scans make up one frame. The time between scans is 1/50th of a second. This system works fine for conventional video cameras and results in a smooth, full-motion picture.
However, the time gap between scan’s causes blur and slight information loss when the image is paused. So in a conventional DV camera with snapshot, the still image that is recorded is only half of the line resolution of the CCD.
