Battery Life When Recording on DV Format Video Explained
When recording in DV format video, your camera is dependent on a battery for power. There are many factors that affect how quickly the battery will be drained, but the most important one is your image sensor. The image sensor is responsible for making your digital video become digital.
Light passes through the lens of your camera and gets projected onto the image sensor, which turns the image into digital data. There are two types of image sensors: CCD (charged coupling device) and CMOS (complementary oxide semi conductor). CCD sensors have been around longer than CMOS sensors, and until recently, were considered to produce higher quality images. They also require more power to operate.
CMOS sensors, on the other hand, do not require as much power, which means that you can shoot longer. Another benefit to CMOS sensors is that they're a lot cheaper to manufacture compared to their CCD counterparts. That means that the prices of camcorders and cameras are going down.
So, to understand battery life when recording on DV, you need to know
which image sensor your camera is working with. Because CMOS sensors
use less power than CCD sensors, you will end up having a longer battery
