EMVA 1288 Standard
The European Machine Vision Association standard EMVA 1288 defines a unified methodology for measuring and reporting image sensor performance. Key parameters include:
Sensitivity Metrics
- Quantum Efficiency (QE) — photon-to-electron conversion efficiency
- Responsivity — output signal per unit irradiance (A/W)
- Absolute Sensitivity Threshold — minimum detectable photon count
Noise Metrics
- Temporal Dark Noise — read noise in electrons RMS
- PRNU — pixel-to-pixel gain variation
- SNR_max — maximum achievable SNR = sqrt(FWC)
Capacity Metrics
- Saturation Capacity (FWC) — maximum charge per pixel
- Dynamic Range — ratio of FWC to noise floor
- Useful Bits — effective ADC resolution considering noise
Grade System
Parameters are color-coded by quality:
- Green — excellent performance for the metric
- Blue — typical/acceptable performance
- Red — below typical, may limit application suitability
TIP
The SNR curve shows actual vs ideal (shot-noise-limited) performance. The gap between curves indicates how much the sensor deviates from ideal photon counting.
