A method for processing signals collected by pixels of a detector, each pixel being able to collect a signal under the effect of radiation to which the detector is subjected comprises: identifying a pixel, termed the affected pixel, generating a signal greater than a threshold, defining at least one adjacent pixel of the affected pixel, and, for each adjacent pixel: selecting a first comparison group associated with the affected pixel and a second comparison group associated with the adjacent pixel, the first and second comparison groups not comprising any pixel in common, comparing signals collected by each comparison group so as to determine the comparison group that has accumulated the most significant amount of signal.

A detector for imaging and efficiently digitizing a spatial distribution of photon flux includes pixel circuits that compressively encode pixel values generated by integrated analog to digital converters (ADCs). On-pixel digital compression circuits (DCCs) implement compression to increase continuous frame rate by reducing the number of bits per pixel while keeping quantization error below Poisson noise. Several mapping algorithms for photon-counting and charge-integrating detectors and compact digital logic implementations are presented.
