Definition of standard imaging conditions
Set to standard imaging condition I. After setting the electronic shutter mode with a shutter speed of
1/100s, measure the signal outputs (V
screens, and substitute the values into the following formula.
Set to standard imaging condition II. After adjusting the luminous intensity to 20 times the intensity with the
average value of the Gr signal output, 150mV, measure the minimum values of the Gr, Gb, R and B signal
outputs.
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, first adjust the average value of
the Gr signal output to 150mV. Measure the average values of the Gr signal output, Gb signal output, R
signal output and B signal output (Gra, Gba, Ra and Ba), and then adjust the luminous intensity to 500
times the intensity with average value of the Gr signal output, 150mV. After the readout clock is stopped
and the charge drain is executed by the electronic shutter at the respective H blankings, measure the
maximum value (V
into the following formula.
Sm = 20
Set to standard imaging condition II. 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
Use a pattern box (luminance: 706cd/m
(Pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0mm) as an IR
cut filter and image at F5.6. The luminous intensity to the sensor receiving surface at this point is defined
as the standard sensitivity testing luminous intensity.
Image a light source (color temperature of 3200K) with a uniformity of brightness within 2% at all angles.
Use a testing standard lens with CM500S (t = 1.0mm) as an IR cut filter. The luminous intensity is adjusted
to the value indicated in each testing item by the lens diaphragm.
