Our Canon IXUS 230 HS review is on the way, but in the meantime we would like to share the resolution chart images and the noise and dynamic range results.
The Canon IXUS 230 HS was announced back in August alongside the Canon IXUS 1100 HS and is the upgrade to the Canon IXUS 220 HS. The major updates have been an increase in optical zoom from 5x to 8x, and a larger 3" rear LCD screen.
Initial results from the labs data show that the Canon IXUS 230 HS handles noise well across the sensitivity range, with results better both the Samsung PL170 and Panasonic Lumix DMC-FS22. As with the Canon IXUS 1100 HS dynamic range results are high, outperforming the Samsung PL170, Panasonic Lumix DMC-FS22 and Nikon Coolpix S8200.
The Canon IXUS 230 HS is available to buy now, with prices starting around £229.
Resolution charts
As part of our image quality testing for the Canon IXUS 230 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 230 HSis capable of resolving up to around 22 (line widths per picture height x100) in its highest quality JPEG files.
Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:
ISO 100, score: 22 (see full image)
ISO 200, score: 22 (see full image)
ISO 400, score: 20 (see full image)
ISO 800, score: 20 (see full image)
ISO 1600, score: 18 (see full image)
ISO 3200, score: 16 (see full image)
Noise and dynamic range
These graphs were produced using data generated by DXO Analyzer.
We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG images from the Canon IXUS 230 HS signal to noise ratio results show a good consistent result throughout the sensitivity range, with the results closely relating to the Nikon Coolpix S8200 upto ISO 1600.

Dynamic range
This chart indicates that the Canon IXUS 230 HS's JPEGs dynamic range results are consistently high beating the Samsung PL170, Nikon Coolpix S8200 and Panasonic Lumix DMC-FS22. This shows that the Canon IXUS 230 HS is capible of resolving a higher than average amount of shadow and highlight detail across the sensitivity range.
