This paper investigates the application of Noise Equivalent Quanta (NEQ) as a comprehensive metric for assessing dynamic range in imaging systems. Building on previous work that demonstrated NEQ’s utility in characterizing noise and resolution trade-offs in imaging systems using the Dead Leaves technique, this study seeks to validate the use of NEQ for dynamic range characterization, especially in high-dynamic-range (HDR) systems where conventional metrics may fall short. This paper makes use of previous work that showed the possibility to measure noise and NEQ on the dead leaves pattern which is otherwise typically used for the measurement of the loss of low contrast fine details, also called texture loss. This shall now be used to improve the measurement of the dynamic range.
