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 Canon IXUS 500 HS handles noise well and compares closely with the Samsung WB750 from ISO 200. The dynamic range results are also consistent across the sensitivity range, and whilst the scores are good it is beaten by both the Samsung WB750 and Panasonic FX90 at all sensitivities.
However with a minimum score of 8.35 for dynamic range at ISO 3200 it still puts in a good performance, showing that it will capture a good amount of detail even at its highest sensitivity value in low light conditions.
JPEG Signal to Noise Ratio
JPEG images from the Canon IXUS 500 compare closely with the Samsung WB750 from a sensitivity of ISO 400. At the higher end of the sensitivity range results stay just above 30, showing that although noise will appear in images it is acceptable and handled well for a compact.
