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.
Signal to noise ratio
JPEG images from the Sony HX10V show similar signal to noise ratio results to Nikon Coolpix S9300 throughout its sensitivity range, and also produces similar results to the Sony HX9V between ISO 400 and ISO 800. The camera produces stronger results than the Panasonic TZ25 and Sony HX20V at every ISO setting.
In contrast, images from the Sony HX10V are the weakest of all the other cameras in terms of dynamic range. Its results almost line up with those of the Sony HX20V between ISO 100 and ISO 200, and are most similar to those of the Nikon Coolpix S9300 between ISO 200 and ISO 400, but they tail off after that. The camera consistently performs weaker than the Panasonic TZ25 and Sony HX9V.
