Initial results from the labs data show that the Canon IXUS handles noise well at the low to mid sensitivity range, although it does become an issue above ISO 1600. However, when it comes to dynamic range the results are impressive with dynamic range beating the Samsung WB700 and Olympus XZ-1 at all sensitivities.
As part of our image quality testing for the Canon IXUS 1100 HS, we've shot our resolution chart.
If you view our crops of the resolution chart's central section at 100% (or Actual Pixels) you will see that, for example, at ISO 100 the Canon IXUS 1100 HS is capable of resolving up to around 22 (line widths per picture height x100) in its highest quality JPEG files.
