Resolution Charts

Shots here are of the PIMA/ISO 12233 standard resolution test chart (more available for comparison in our cameras database). How to read the charts: All values are 1/100 th lines/picture height. So the "10" value equates to 1000 lines/picture height.

"What, you're comparing it to the Coolpix 990?", I hear you cry. Well, my logic is that the S1 Pro should be much better because of FujiFilm's SuperCCD technology. Pixel counts are similar (Nikon Coolpix 990 3.14 million effective, FujiFilm S1 Pro 3.07 million effective). For reference we've shot the resolution chart at both 3040 x 2016 and 2304 x 1536.

FujiFilm S1 Pro (@ 3040 x 2016) Nikon Coolpix 990 (@ 2048 x 1536)

FujiFilm S1 Pro (@ 2304 x 1536) Nikon Coolpix 990 (@ 2048 x 1536)

Well there you are, interestingly the S1 Pro shows much higher resolution than the Coolpix 990 (probably not just down to the CCD but also the lens) but has some strange artifacts (and moiré aliasing) visible in angular lines as blue or yellow artifacts - take a look also at fine detail in the images in the samples galleries and you'll see the same thing. A side effect of the SuperCCD's honeycomb design?

Measurable findings (three measurements taken for each camera):

Camera Measurement Absolute Res. Extinction Res.
FujiFilm
Finepix S1 Pro
Horiz LPH 1300 1450
Vert LPH 1200 1400
5o Diagonal LPH * 1000 n/a
Nikon
Coolpix 990
Horiz LPH 900 1300
Vert LPH 900 1400
5o Diagonal LPH 900 n/a

* Visible moiré artifacts

Definition of terms:

LPH Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical)
5o Diagonal Lines set at 5o 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)

* Nyquist frequency defined as the highest spatial frequency where the CCD can still faithfully record
image detail. Beyond the Nyquist frequency aliasing occurs
