6. Uniformity between video signal channels
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 maximum (Crmax, Cbmax [mV]) and minimum (Crmin, Cbmin
[mV]) values of the R – Y and B – Y channels of the chroma signal and substitute the values into the
following formula.
Sr = | (Crmax – Crmin)/200 |
×
100 [%]
Sb = | (Cbmax – Cbmin)/200 |
×
100 [%]
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. 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)
9. 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)
