Interlaced (the opposite of progressive) CCD units read an interlaced image in two passes, similar to the way a TV displays an image. • Batteries: • What are the best choices? Lithium for disposables or NiMH for rechargeables, probably. Note that lithium batteries are very expensive, around $9-$15 for a set of four, but also last a really long time. (Tip: Home Depot carries lithium AA batteries for $4.17 for a two-pack, making a set of four just $8.34. Wal-Mart charges $4.97 for a two-pack, making a set of four just $9.94). NiMH batteries are supposed to be better than NiCd batteries for rechargeables. Olympus sells NiMH batteries for the D-320L. The bad news is that NiMH batteries are rumored to suffer from rapid loss of charge when not being used (I’ve heard 3-5% loss per day). NiCd batteries lose charge much more slowly ( Tip: if you decide to use NiCd batteries, try to get the new
