We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using DXO Analyzer software to generate the data to produce the graphs below.
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
Our analysis shows that the Olympus SZ-14 has better signal to noise ratio results than the Canon IXUS125 HS at all but ISO 80, and the Nikon Coolpix S8200 at all sensitivities but ISO 1600. At all other sensitivities the SZ-14 out performs the comparison cameras. When it comes to dynamic range the charts show that the competition all have better results except at the higher end of the sensitivity scale where the SZ-14 just takes the lead.

JPEG Signal to Noise Ratio
JPEG images from the Olympus SZ-14 show better signal to noise ratio across the sensitivity range than the comparison cameras, except for the Canon IXUS 125 HS at ISO 80 and the Nikon Coolpix S8200 at ISO 1600.
