By adding stabilization and super-sampling to a digital pixel readout integrated circuit (ROIC), line of sight motion, that is usually costly and difficult to control, instead becomes an ally, doubling the effective FPA resolution in some systems. The base repartitioned digital pixel architecture supplements analog signal accumulation with off-pixel digital accumulation, greatly increasing dynamic range. Adding address mapping and increasing the ratio of memory locations to pixels, enables stabilization and resolution enhancement. Additional stabilization at sub-frame intervals limits the effect of latency and simplifies complex address mapping. Pixels gains are compensated in-ROIC, without requiring multipliers. A unique partitioning of functions between the ROIC and subsequent logic allows pixel biases and non-isomorphic sampling effects to be compensated off-ROIC, reducing overall system complexity and power.
