The WB1100F has a CCD sensor type which is better than the MOS sensor type found on most cameras that have been available for a comparable time to 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.
A CCD sensor type is actually the best sensor type amongst all digital cameras of this age and spec.
A MOS sensor type is the worst sensor type amongst comparable types of digital camera.
