Analog Read Noise and Quantizer Threshold Estimation From Quanta Image Sensor Bit Density
Estimation of the analog read noise level and quantizer threshold level to within a few hundredths of an electron can be obtained by measuring the output bit density, D, of a single-bit quanta image sensor (1bQIS) as a function of quanta exposure, H. Analysis of the D-H characteristics as a function...

| Summary: | Estimation of the analog read noise level and quantizer threshold level to within a few hundredths of an electron can be obtained by measuring the output bit density, D, of a single-bit quanta image sensor (1bQIS) as a function of quanta exposure, H. Analysis of the D-H characteristics as a function of read noise and quantizer threshold levels is performed and a procedure for extraction of estimated read noise and quantizer threshold is suggested and demonstrated. |
