Sensor
Larger, higher-resolution CCDs contribute significantly to better image quality. Sensor sizes in consumer camcorders generally range between 1/6 and 1/3 of an inch, and resolutions usually fall between 300,000 pixels and 1 megapixel per CCD. When you compare cameras, look at effective resolutions instead of gross sensor resolutions. Hobbyists and semipros should opt for a three-CCD camcorder: it will deliver better color rendition and fewer image artifacts than a single CCD. Progressive-scan CCDs also produce better image quality than interlaced sensors, especially for stills. However, shooting video in progressive-scan mode results in jerkier footage; some people prefer this look for its "filmlike" quality. Read the product information carefully if you're looking for progressive scan, since some vendors use misleading language to describe features that merely imitate true progressive scan.
