5. 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 signal output is 200mV. Then measure the maximum (Vmax [mV]) and

minimum (Vmin [mV]) values of the signal output and substitute the values into the following formula.

SH = (Vmax – Vmin)/200

× 100 [%]

6. 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.

7. Dark signal shading

After measuring 6, 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]

8. Flicker

Set to standard imaging condition III. Adjust the luminous intensity so that the average value of the signal

output is 200mV, and then measure the difference in the signal level between fields (

∆Vf [mV]). Then

substitute the value into the following formula.

F = (

∆Vf/200) × 100 [%]

9. Lag

Adjust the signal output value generated by strobe light to 200mV. 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/200)

× 100 [%]
