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.
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.
ΔYdt = Ydmax – Ydmin [mV]
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 (ΔYf [mV]). Then
substitute the value into the following formula.
Fy = (ΔYf/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 (ΔCr, ΔCb) as well as the average value of the chroma signal output (CAr, CAb).
Substitute the values into the following formula.
Fci = (ΔCi/CAi) × 100 [%] (i = r, b)
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 (ΔYlw, ΔYlr, ΔYlg, ΔYlb [mV]). Substitute the values into the
following formula.
Lci = (ΔYli/200) × 100 [%] (i = w, r, g, b)
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 [%]
