New York -- By
almost every measure, small-format HD cameras should be worse than
their larger counterparts. So why do their pictures seem so good?
They
are HDTV and do use technologies available 25 years after the first
broadcast solid-state camera. But, can a 1/6-inch-format $200 HD
camcorder, or even a 1/3-inch-format $5,000 HD camcorder, perform as
well as a $25,000-and-up 2/3-inch-format camera?
No. All else
being equal, each pixel’s individual sensor on the smaller-format
imager (chip converting images into video signals) is smaller. Less
area means less dynamic range (contrast ratio).
