Sony DSC-P9 Review
Compared to... (contd.)
Now we'll use the data in our review database to compare the P9's colour and resolution to three other four megapixel digital cameras: the Canon PowerShot S40, Olympus C-40Z and Sony DSC-S85.
Colour Chart Comparison
Colour charts are shot in daylight, Auto White Balance, EV compensation +0.3 (all cameras), measured light ~10 EV. This test is also dependent on the accuracy of the camera's auto white balance, the colour charts are shot in daylight but some camera's white balance is better than others. All cameras are given 20 seconds to "settle" before the shot is taken.
|Sony DSC-P9||Canon PowerShot S40|
|Olympus C-40Z||Sony DSC-S85|
In the table below we're only measuring colour. The RGB values were measured from a VGA reduced image (to average colours, remove noise and eliminate JPEG artifacts) using the Eyedropper tool in Photoshop with a 5 by 5 Average Sample Size.
Again, it's fairly easy to see the 'red bleed' into the dark blue patch, this has had the effect of turning this patch purple (this appears to be a daylight auto white balance issue).
Resolution Chart Comparison
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. So a value of 8 equates to 800 lines per picture height.
Studio light, cameras set to auto, all settings factory default. Exposure compensation +0.7 EV for all cameras.
|Horizontal resolution||Vertical resolution||5 degree diagonal res.|
|Canon PowerShot S40|
Measurable findings (three measurements taken for each camera):
|Camera||Measurement||Absolute Res.||Extinction Res.|
|Sony DSC-P9||Horiz LPH||1100||1400|
|5° Diagonal LPH||1000||n/a|
|Canon PowerShot S40||Horiz LPH||1250||*1400|
|5° Diagonal LPH||1000||n/a|
|Olympus C-40Z (D-40Z)||Horiz LPH||*1200||*1350|
|5° Diagonal LPH||1000||n/a|
|Sony DSC-S85||Horiz LPH||1250||*1650|
|5° Diagonal LPH||1000||n/a|
* Some artifacts / moiré visible
Definition of terms:
|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 Resolution||Still defined detail (below Nyquist frequency*)|
|Extinction Resolution||Detail beyond camera's definition (becomes a solid gray alias)|
|n/a||Not Available (above the capability of the test chart)|
|n/v||Not Visible (not visible on test results)|
image detail. Beyond the Nyquist frequency aliasing occurs.
The DSC-P9 performed pretty much as we'd expected, based on what we've seen from its sample images and in comparison to the S40. Horizontal resolution is around (but just slightly less) than some of the other competition, vertical resolution is identical to the S40 and C-40Z (D-40Z). The DSC-S85 was included for comparison, as you can see it still manages to hold onto its crown for the highest resolution four megapixel consumer digital camera.
