The S5K3A1EA is highly integrated single chip CMOS image sensor, fabricated by SAMSUNG
0.18um CMOS image sensor process technology. It is developed for image application to realize high
efficiency photo sensor. The sensor has 1280 x 1024 effective pixels with 1/3 inch optical format. The
sensor has on-chip 10-bit ADC blocks to digitize the pixel output and also on-chip CDS to reduce Fixed
Pattern Noise (FPN) drastically. With its few interface signals and 10-bit raw data directly connected to
the external devices, a camera system can be configured easily.

NOTES:
1. Measured minimum output level at 100 lux illumination for exposure time 1/30 sec. 7X7 rank filter is applied for the whole
pixel area to eliminate the values from defective pixels.
2. Measured average output at 25% of saturation level illumination for exposure time 1/30 sec. Green channel output values
are used for color version.
3. Measured average output 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 for 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 for 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 rows at 25% of saturation level illumination for exposure time 1/30 sec.
