Video Performance* (9.75)*
The Samsung SC-HMX20 is equipped with an enormous 1/1.8-inch CMOS. The gross pixel count is 6,400,000, with an effective pixel count of 4,000,000. A sensor this big—particularly a CMOS as opposed to CCD sensor—should theoretically produce amazing low light performance. (We'll explore that in detail later down the page.) The pixel density, however, is quite high, which could cut into some of those potential gains in surface area.
