The Life X44022 has a CCD sensor type which is better than the MOS sensor type found on most bridge camera digital cameras that have been around for around the same time as it. CCD sensors produce high quality, low-noise images but consume a lot more power than CMOS sensors. CCD is the most common image sensor type used in digital cameras.
This camera's sensor type (CCD) is in fact the best sensor type across all recently released comparable spec cameras.
A MOS sensor type is the worst sensor type across similar types of camera.
