Measurement conditions
Definition of standard imaging conditions
Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of
1/250s, measure the signal output (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
average value of the signal output, 200mV, measure the minimum value of the signal output.
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity to
500 times the intensity with average value of the signal output, 200mV. When 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.
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 200mV. 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)/200
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.
indicated on the device, and the device drive conditions are at the typical values of the bias and clock
voltage conditions.
black (OB) level is used as the reference for the signal output, and the value measured at point [ A] in the
drive circuit example is used.
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.
