S5K433CA Datasheet, PDF (9/25 Pages) Samsung semiconductor – 1/4 Optical Size 640x480(VGA) 3.3V/2.8V VGA CMOS Image Sensor

1/4 INCH VGA CMOS IMAGE SENSOR
S5K433CA, S5K433LA
Imaging Characteristics
(Light source with 3200K of color temperature and IR cut filter (CM-500S, 1mm thickness) is used. Electrical
operating conditions follow the recommended typical values. The control registers are set to the default values. T_A
= 25°C if not specified.)

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 columns at 25% of saturation level illumination for exposure time 1/30 sec.
