WebThe photon transfer curve is one of the most valuable tools for calibrating, characterizing, and optimizing the performance of CCDs and CMOS Imagers. Its primary purpose is to determine the conversion gain of the system from camera which many of the other performance parameters such as read noise, dark current, QE, full well etc. are determined. WebMay 16, 2024 · The low endpoint for Engineering Dynamic Range is determined by where the SNR curve crosses the value of 1. Here is an extreme close-up of that area of the Photon Transfer Curve: The ISO 100 line crosses 0 (the log 2 (1)) at 1.63 EV. So Engineering Dynamic Range is 14.00 EV - 1.63 EV = 12.37 EV.
