Signal to
A temporal noise measurement is made with the image sensor in the dark and analog
gain changed to the maximum setting of 4X. Signals are measured in LSB on the sensor
output. Two consecutive dark frames are captured. Temporal noise is calculated as the
average pixel value of the difference frame:
The dynamic range is calculated according to the following formula:
A flat-field light source (90 lux, color temperature 4400K, broadband, with IR cut filter) is
used as an illumination source. Signals are measured in LSB on the sensor output. Two
consecutive illuminated frames are captured. Temporal noise is calculated as the
average pixel value of the difference frame (according to the formula shown in Test 4).
The signal-to-noise ratio is calculated as the ratio of the average signal level to the
temporal noise according to the following formula:
Where S
measured for the i-th pixel from the second frame, and N
els contained in the array.
Where
Where σ
measured for the i-th pixel from the first frame, and N
contained in the array.
