13-4 Measurement method
Sensitivity
Set the measurement condition to the standard imaging condition I. After setting the luminous intensity
of 10 times that of the standard imaging condition and the electronic shutter mode with a shutter speed
of 1/150 s, measure the Gr and Gb signal outputs (VGr, VGb) at the center of imaging area, and
substitute the values into the following formula.
S = {((VGr + VGb)/2) × (1/10) × (150/120)} [LSB]
Sensitivity ratio
Set the measurement condition to the standard imaging condition II. After adjusting so that the average
value of the Gr and Gb signal output is 333 [LSB], measure the R signal output (VR [LSB]), the Gr and
Gb signal outputs (VGr, VGb [LSB]) and the B signal output (VB [LSB]) at the imaging area Center in
frame readout mode, and substitute the values into the following formulas.
VG = (VGr + VGb)/2
RG = VR/VG
RB = VB/VG
Saturation signal
Set the measurement condition to the standard imaging condition II. After adjusting the luminous
Intensity to 20 times the intensity with the average value of the Gr, Gb signal outputs, 333 [LSB],
measure the average value of the Gr, Gb, R and B signal outputs.
Video signal shading
Set the measurement condition to the standard imaging condition III. With the lens diaphragm at F2.8,
adjust the luminous intensity so that the average value of the Gr and Gb signal outputs is 333 [LSB].
Then measure the maximum value (Gmax [LSB]) and minimum value (Gmin [LSB]) of the Gr and Gb
signal outputs, and substitute the values into the following formula.
SH = ((Gmax  Gmin)/Gmax) × 100 [%]
Dark signal
Measure the output difference between 1/15 [s] signal output (Va) and 1/15000 or less [s] signal output
