Signal to noise ratio

A high signal to noise ratio (SNR) indicates a cleaner and better quality image.

This chart indicates that the Canon PowerShot SX40 HS's JPEGs are an improvement over the Canon PowerShot SX30 IS and just take the lead over the Sony Cyber-shot HX100V from a sensitivity of ISO 800. This shows that the Canon PowerShot SX40 is capible of capturing a more shadow and highlight detail in low light conditions than the Sony HX100V, Panasonic Lumix DMC-FZ48 and Canon PowerShot SX30 IS.
