These graphs were produced using data generated by DXO Analyzer.
We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG images from the Nikon Coolpix S9100 produce a good signal to noise ratio when compared with the Panasonic Lumix DMC-TZ20, Canon IXUS 220 HS and Fujifilm Finepix 550 EXR, beating all but the Canon IXUS 220 HS at ISO 800.
Dynamic range
This chart indicates that the Nikon Coolpix S9100's JPEGs have a at least a 0.5EV lower dynamic range than the comparison cameras up to a sensitivity of ISO 800.
