Imaging Characteristics
(Light source with 3200K of color temperature and IR cut filter (CM-500S, 1mm thickness) are used. It is
recommended that the sensor should operate in compliance to the following typical values. The control registers
are set to the default values. T

NOTES:
1. Minimum output level measured at 100 lux illumination for exposure time 1/30 sec. 7X7 rank filter is applied to the
whole pixel area to eliminate the values from defective pixels.
2. Average output measured at 25% of saturation level illumination for exposure time 1/30 sec. Green channel output
values are used for color version.
3. Average output measured at zero illumination without any offset compensation for exposure time 1/30 sec.
4. 20 log (saturation level/ dark level rms noise excluding fixed pattern noise). 60dB is limited by 10-bit ADC.
5. 20 log (average output level/rms noise excluding fixed pattern noise) at 25% of saturation level illumination for exposure
time 1/30 sec.
6. Difference between maximum and minimum pixel output levels at zero illumination for exposure time 1/30 sec. 7X7
median filter is applied to the whole pixel area to eliminate the values from defective pixels.
7, Difference between maximum and minimum pixel output levels divided by average output level at 25% of saturation
level illumination for exposure time 1/30 sec. 7X7 median filter is applied to the whole pixel area to eliminate the values
from defective pixels.
8. For the column-averaged pixel output values, maximum relative deviation of values from 7-depth median filtered values
for neighboring 7 columns at 25% of saturation level illumination for exposure time 1/30 sec.
9. For the row-averaged pixel output values, maximum relative deviation of values from 7-depth median filtered values for
neighboring 7 columns at 25% of saturation level illumination for exposure time 1/30 sec.
