7. Dark signal

Measure the average value of the Y signal output (Ydt [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.

8. Dark signal shading

After measuring 7, measure the maximum (Ydmax [mV]) and minimum (Ydmin [mV]) values of the Y signal

output and substitute the values into the following formula.

∆Ydt = Ydmax – Ydmin [mV]

9. Flicker

1) Fy

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

output is 200mV, and then measure the difference in the signal level between fields (∆Yf [mV]). Then

substitute the value into the following formula.

Fy = (∆Yf/200) × 100 [%]

2) Fcr, Fcb

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

output is 200mV, insert an R or B filter, and then measure both the difference in the signal level between

fields of the chroma signal (∆Cr, ∆Cb) as well as the average value of the chroma signal output (CAr, CAb).

Substitute the values into the following formula.

Fci = (∆Ci/CAi) × 100 [%] (i = r, b)

10. Line crawls

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

output is 200mV, and then insert a white subject and R, G, and B filters and measure the difference

between Y signal lines for the same field (∆Ylw, ∆Ylr, ∆Ylg, ∆Ylb [mV]). Substitute the values into the

following formula.

Lci = (∆Yli/200) × 100 [%] (i = w, r, g, b)

11. Lag

Adjust the Y 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 (Ylag). Substitute the value into the following

formula.

Lag = (Ylag/200) × 100 [%]
