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. Uniformity between video signal channels

After measuring 4, measure the maximum (Rmax [mV]) and minimum (Rmin [mV]) values of the R signal

and the maximum (Bmax [mV]) and minimum (Bmin [mV]) values of the B signal, and substitute the values

into the following formulas.

∆Srg = (Rmax – Rmin)/150 × 100 [%]

∆Sbg = (Bmax – Bmin)/150 × 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. 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)

9. 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 [%]
