How a Low Power CMOS Can Save Battery

Low power CMOS sensors are one of the greatest advancements in digital camera technology during the past decade. Digital imaging was first made possible through CCD image sensors that produced great images, but also required frequent battery changes during a day of shooting. Those CCD image sensors are quickly being replace with power efficient CMOS sensors. While battery changes are still necessary, you don't need to do them as frequently.

CMOS chips, by their nature, don't consume a lot of power. Aside from not draining your batteries quickly they also don't produce a lot of heat. This allows you to shoot images that aren't corrupted by thermal electronic noise. It also make it possible to create larger image sensors that create higher quality images. They're also inexpensive to mass produce compared to CCD image sensors. This has a lead to a decrease in the price of digital cameras.

A CMOS camera requires less power from the battery than it's CCD counterpart. This allows you to shoot longer without having to swap out the battery. But, if you're in a situation where you have to spend a couple hours constantly shooting then you might be better off leaving the camera continuously on instead of always turning it on and off. CMOS sensors only consume a lot of juice when powering on and off.
