Performance Specifications
Notes:
Table 15 summarizes the specification for each performance parameter.
Performance definitions are detailed in the following sections.
A flat-field light source (90 lux, color temperature 4400K, broadband, w/ IR cut filter) is
used as an illumination source. Signals are measured in LSB on the sensor output. A
series of four frames are captured and averaged to obtain a scalar sensitivity output
code.
The image sensor is held in the dark. Analog gain is changed to the maximum setting of
4X. Signals are measured in LSB on the sensor output. A series of four frames are
captured and averaged (pixel-by-pixel) into one average frame. DSNU is calculated as
the standard deviation of this average frame.
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
series of four frames are captured and averaged (pixel-by-pixel) into one average frame,
one series is captured under illuminated conditions, and one is captured in the dark.
PRNU is expressed as a percentage relating the standard deviation of the average frames
difference (illuminated frame - dark frame) to the average illumination level:

tested without a lens. Multiple images were captured and analyzed.
Setup: VDD = VAA = VAAPIX = LVDSVDD = 3.3V. Testing was done with default frame timing and default
register settings, with the exception of AEC/AGC, row noise correction, and auto black level, which were
disabled.
