Resolution Chart Comparison
Comparison cameras:
- HP Photosmart R707 (5 mp, 3x zoom)
- Canon PowerShot S60 (5 mp, 4x zoom)
- Samsung Digimax V50 (5 mp, 3x zoom)
- Sony Cyber-Shot DSC-F88 (5 mp, 3x zoom)
Shots here are of the PIMA/ISO 12233 standard resolution test chart (more of which are available in our comparison database). This resolution chart allows us to measure the actual performance of the lens and sensor system. It measures the ability of the camera to resolve lines at gradually higher resolutions and enables us to provide a definitive value for comparison purposes. Values on the chart are 1/100th lines per picture height. Thus a value of 15 equates to 1500 lines per picture height.
Studio light, cameras set to auto, all settings factory default. If possible aperture was selected for optimum sharpness. Exposure compensation +0.7 EV to +1.3 EV.

| LPH | Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical) |
| 5° Diagonal | Lines set at 5° diagonal |
| Absolute res. | Point at which all lines of a resolution bar are still visible and defined, beyond this resolution loss of detail occurs (below Nyquist frequency). |
| Extinction res. | Detail beyond camera's definition (becomes aliased) |
| n/a | Not Available (above the capability of the test chart) |
| n/v | Not Visible (not visible on test results) |
The R707 is certainly no slouch when it comes to resolving fine detail, and the images are pretty clean too. It is outperforming the Sony DSC-F88, and isn't far off the Canon S60 or Samsung V50 - two of the best 5MP compacts we've tested recently.
