4. Video signal shading
Set to the standard imaging condition III. With the lens diaphragm at F5.6 to F8, adjusting the luminous
intensity so that the average value of the Gr signal output is 150mV. Then measure the maximum value
(Grmax [mV]) and minimum value (Grmin [mV]) of the Gr signal output and substitute the values into the
following formula.
SHg = (Grmax – Grmin)/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. Line crawl
Set to the standard imaging condition II. Adjusting the luminous intensity so that the average value of the
Gr signal output is 150mV, and then insert R, G and B filters and measure the difference between G signal
lines (∆Glr, ∆Glg, ∆Glb [mV]) as well as the average value of the G signal output (Gar, Gag, Gab).
Substitute the values into the following formula.
Lci =

× 100 [%] (i = r, g, b)
8. Lag
Adjust the Gr signal output value 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 [%]
