converts visible light into an electronic signal, which the camcorder reads and stores to tape. Generally, the bigger the CCD the better; broadcast camcorders often have 1/2-inch to 2/3-inch CCDs, while consumer camcorders usually have them within the window of 1/6-inch to 1/3-inch. The larger the CCD, the more light is taken in with the image, resulting in brighter pictures with better colors. CCD size becomes quite important in low light situations. CCD sizes in consumer camcorders vary with every model and manufacturer, and always should be considered. The difference between a 1/6-in. and a 1/4-in. CCD may seem small, but when those values are squared to measure the surface area, it has a large effect on video and low-light quality.
The other key distinction is the difference between one and three CCDs. Professional camcorders always have three CCDs, one for each
