AI Technical Summary
Photon counting accuracy is degraded in CMOS image sensors due to readout noise, gain, and offset value variations among pixels, which hinder accurate photon discrimination during binning processes.
A photon counting device and method that includes a CMOS image sensor with a correction unit to adjust digital values based on common gain and offset values, using a computer to correct and convert digital values to photon counts, thereby minimizing the impact of pixel variations.
The solution effectively curbs the degradation of photon counting accuracy by ensuring consistent digital value corrections, allowing precise photon counting with reduced readout noise and improved discrimination between electron counts.
