4. Video signal shading
Set to standard imaging condition III. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity
so that the average value of the Gr signal output is 150mV. Then measure the maximum (Grmax [mV]) and
minimum (Grmin [mV]) values 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 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 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 = ∆Gli/Gai × 100 [%] (i = r, g, b)
8. Lag
Adjust the Gr signal output value generated by strobe light to 150mV. After setting the strobe light so that it
strobes with the following timing, measure the residual signal (Vlag). Substitute the value into the following
formula.
Lag = (Vlag/150) × 100 [%]
