Abstract: The accumulation of registered sub-frame residuals in an address-mapped repartitioned digital pixel matches the intensity resolution (dynamic range) to the spatial resolution of the image. The digital accumulation of pixel quantization events (QEs) is extended to include sub-frame residuals. After all QEs are digitally accumulated, then removed from the analog accumulator, an analog residual value remains. Residual capture logic is configured to trigger residual digitization logic at least twice per frame interval for selected pixels to capture, digitize and then clear the residual value on the storage device. Memory update logic is configured to accumulate the quantization event digital values and residual digital values into existing digital values at the address-mapped memory locations in digital memory. Resolution enhancement is enabled by an address mapping that maps a one-pixel spacing on the detector to two or more pixel spacing in the digital memory.

Abstract: 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.
