Region of interest with slanted-edge

ROI(Region of interest) with slanted-edge

“ROI 158x291 (26%)” means - ROI size 158x291 and 26% of the distance to the corner.

Accuracy 100%(5.71 degs) means 100% scanned lines of the ROI processed successfully and edge angle equals approximately 5.71 degrees.

Most important measurements:
  CA (chromatic aberration)
  MTF50 (50% contrast spatial frequency)
  10-90% rise distance

Most important image quality measurements - CA(chromatic aberration), MTF50(50% contrast spatial frequency) and 10-90% rise distance

CA=0.54pix(0.03%PH, 0.13%fc) means the area chromatic aberration equals 0.54 pixels, 0.03% per image height and 0.13% of the distance from image centre

MTF50: 0.320 c/p (1244.2 LPH) means 50% contrast spatial frequency equals 0.320 cycles per pixel or 1244.2 lines per image height

10-90% rise: 1.21 pix (1600.3 PH) means 10-90% (of maximum energy) rise distance equals 1.21 pixels or 1600.3 rises per image height

Spatial frequency by contrast

Spatial frequency by user defined MTF level (contrast)

 MTF47: 0.325 c/p (1263.6 LPH) means 47% contrast spatial frequency equals 0.320 cycles per pixel or 1244.2 lines per image height. Drag the slider to define contrast

Rise distance by rise range

Rise distance by user defined range

 13-87% rise: 1.10 pix (1760.7 PH) means 13-87% rise distance equals 1.10 pixels or 1760.7 rises per image height. Drag the slider to define interested range

MTF level by spatial frequency

MTF level by user defined spatial frequency

 MTF28 at 0.36 c/p means spatial frequency 0.36 cycles per pixel corresponds to 28% contrast

Noise measurements

Noise measurements

Dsh(45.1) = 1.22(max 6.8) means dispersion of high-frequency noise in shadows equals 1.22, average signal level equals 45.1. Maximum quadratic deviation equals 6.8

Dhi(189.1) = 1.30(max 8.0) means dispersion of high-frequency noise in highlights equals 1.30, average signal level equals 189.1. Maximum quadratic deviation equals 8.0
