Measurement conditions
Definition of standard imaging conditions
Set to standard imaging condition I. After setting the electronic shutter mode with a shutter speed of
1/250s, measure the signal voltage (Vs) at the center of the screen, and substitute the value into the
following formula.
S = Vs
Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with the
average value of the signal output, 150mV, measure the minimum value of the signal output.
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, first adjust the luminous intensity
to 500 times the intensity with the average value of signal output, 150mV. Then 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 (VSm [mV]) of the signal output and substitute the value 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 signal output is 150mV. Then measure the maximum (Vmax [mV]) and
minimum (Vmin [mV]) values of the signal output and substitute the values into the following formula.
SH = (Vmax – Vmin)/150
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.
voltage conditions.
black level (OB) is used as the reference for the signal output, which is taken as the value measured at
point [ B] of the measurement system.
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 F8. 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.
