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.
For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.
Our analysis shows that the Ricoh CX6 produces good results for both signal to noise ratio and dynamic range. For signal to noise ratio the CX6's results are on par with Canon IXUS 230 HS and Nikon Coolpix S8200 up to a sensitivity of ISO 800, above this value the CX6 out performs the others, showing less noise at the higher sensitivities. Dynamic range results again show that the CX6 just has the edge across the whole sensitivity range.
Signal to noise ratio
JPEG images from the Ricoh CX6 compare well against the Canon IXUS 230HS and Nikon Coolpix S8200 up to a sensitivity of ISO 800. From ISO 800 the results remain consistent showing noise is kept to a minimum at the higher sensitivities and out performing the other cameras.
This chart indicates that the Ricoh's JPEGs have at least a 1EV higher dynamic range than the Canon IXUS 230HS and Nikon Coolpix S8200 at ISO 100. Although results between sensitivities of ISO 400 and 1600 are similar to the Canon IXUS 230HS, at the highest sensitivity setting the Ricoh again gains a better result.
