MESUREMENT METHOD
Ai329CA
1. Sensitivity
˝ Set to SILC ( Standard Illumination Conditions* )
˞ Measure the average value of signal output ( V_OUT )
˟ Calculate the efficiency of V_OUT to light intensity
2. V_SAT
˝ Adjust light intensity to 200 times of SILC
˞ Measure the average value of signal output
3. Smear
˝ Adjust light intensity to 200 times of SILC & readout clock
˞ Measure the signal output at horizontal optical black ( V_HOPB )
˟ Measure the signal output at vertical blanking dummy ( V_VBD )
ˠ Smear = { (V_VBD - V_HOPB) / V_SAT } ƒ 100 ( % )
4. Blooming
˝ Adjust light intensity to 200 times of SILC & readout clock
˞ Measure the signal output at horizontal optical black (V_HOPB )
˟ Measure the signal output at blooming dummy area ( V_BD )
ˠ Blooming = { ( V_BD - V_HOPB ) / V_SAT } ƒ 100 ( % )
5. OSNU
˝ Set to SILC
˞ Measure the average value of signal output ( V_OUT )
˟ Measure the maximum value and the minimum value of signal output
ˠ OSNU = ( V_MAX - V_MIN ) / V_OUT ƒ100 (%)
6. ǚSr,ǚSb
˝ Set to SILC
˞ Measure the average value of signal output ( V_OUT )
˟ Measure the maximum value and minimum value of chroma output
ǚSr = Ȉ( Cr_MAX - Cr_MIN ) / V_OUT Ȉƒ100 (%)
ǚSb= Ȉ( Cb_MAX - Cb_MIN ) / V_OUT Ȉƒ100 (%)
7. V_DARK
˝ Measure the average value of signal output at dark condition
8. DSNU
˝ Measure the voltage difference between minimum and maximum of dark signal
