The GE X450 has a better sensor type than most digital cameras of this age and spec. This digital camera has a CCD sensor type, whereas most digital cameras that have been around for around the same time as it have a MOS sensor type. 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.
A CCD sensor type is in fact the best sensor type amongst all bridge camera digital cameras that have been around for around the same time as the X450.
A MOS sensor type is the worst sensor type amongst similar types of digital camera.
