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 Samsung WB700 just beat the Panasonic Lumix DMC-TZ20 signal to noise ration score at ISO 100. From ISO 200 results for the WB700 are less impressive than the comparison cameras.
This chart indicates that the Samsung WB700's JPEGs compare well with the Panasonic TZ20 up to ISO 200, but as the sensitivity increases its perfomance drops off.
