Unit
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 X
ave
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.
