摘要： 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.
