<Inspection conditions>
Ta=25˚C, VDD=12V, VøH=VVH=VSH=VRH=5V (pulse), fC=fR=1MHz, Tint (accumulation time)=10ms
Light source: Daylight fluorescent lamp with IR/UV cutting filter
Optical system: A slit with an aperture dimensions of 20mm
× 20mm is used at a distance of 200mm from the sensor (equivalent
to F=10).
Load resistance = 100k Ohms
These specifications apply to the 512 valid R and G pixels and the 1024 valid G pixels excluding the dummy pixels D1 to D8.
Note 1) Responsivity (R)
This is the value obtained by dividing the average output voltage (V) of the all pixels by the exposure (lx· s).
The exposure (lx· s) is the product of the illumination intensity (lx) and the accumulation time (s).
Since the responsivity changes with the spectral distribution of the light source used, care should be taken when using a
light source other than the daylight type fluorescent lamp specified in the inspection conditions.
Note 2) Photo response non-uniformity (PRNU)
This is defined by the following equation where Xave is the average output voltage of the valid pixels of each of the colors
R, G, and B, and
∆x is the difference between the output voltage of the maximum (or minimum) output pixel and X
ave,
when the photodetector region is illuminated with light of a uniform illumination intensity distribution.
The incident light intensity shall be 50% of the standard saturation llight intensity.
