  1. Dynamic Range DR(dB) = 20*log(Vsat / Vnoise) Example: 1V max linear output from pixel 200uV input referred read noise DR = 74 dB

  2. Stouffer Chart

  3. Reading the chart Enhance contrast, and find last visible step. Every step is 2dB in dynamic range.

  4. HDR sensor Stouffer Chart Tint2 Tint1 Tint3 All the bars are visible to 41 > 82dB dynamic range Need a longer Stouffer Chart!
