ICX274AL
4. Video signal shading
Set to the standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjusting the luminous
intensity so that the average value of the signal output is 150mV. Then measure the maximum value (Vmax
[mV]) and minimum value (Vmin [mV]) of the G signal output and substitute the values into the following
formula.
SH = (Vmax – Vmin)/150 × 100 [%]
5. Dark signal
Measure the average value of the signal output (Vdt [mV]) with the device ambient temperature of 60°C
and the device in the light-obstructed state, using the horizontal idle transfer level as a reference.
6. Dark signal shading
After measuring 5, measure the maximum (Vdmax [mV]) and minimum (Vdmin [mV]) values of the dark
signal output and substitute the values into the following formula.
∆Vdt = Vdmax – Vdmin [mV]
7. Lag
Adjust the signal output generated by the strobe light to 150mV. After setting the strobe light so that it
strobes with the following timing, measure the residual signal amount (Vlag). Substitute the value into the
following formula.
Lag = (Vlag/150) × 100 [%]
VD
