Region of interest with slanted-edge
![ROI(Region of interest) with slanted-edge](images/roi_info.jpg)
|
“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](images/base_info.png) |
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)](images/mtr_by_contr.png) |
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](images/us_def_rise.png) |
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](images/mtf_by_frec.png) |
MTF28 at 0.36 c/p means spatial frequency 0.36 cycles per pixel corresponds to 28% contrast |
Noise measurements
![Noise measurements](images/noise_info.png)
|
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 |
