As part of our image quality testing for the Sony Cyber-Shot DSC-TX20, 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 125 the Sony Cyber-Shot DSC-TX20 is capable of resolving up to around 18 (line widths per picture height x100) in its highest quality JPEG files.
For a full explanation of what our resolution charts mean, and how to read them, check out our full explanation of our camera testing resolution charts.
