Notes)
1. In accordance with the given electrooptical characteristics, the black level is defined as the average value of
D18, D19 to D67.
2. For the sensitivity test light is applied with a uniform intensity of illumination.
3. PRNU is defined as indicated below. Ray incidence conditions are the same as for Note 2.
VOUT = 500mV (Typ.)
PRNU = × 100 [%]
(VMAX – VMIN)/2
VAVE
4. Use below the minimum value of the saturation output voltage.
5. Saturation exposure is defined as follows.
VSAT
SE =
R
Where R indicates RR, RG, RB, and SE indicates SER, SEG, SE B.
6. Optical signal accumulated time τ int stands at 5.5ms.
7. VOUT-G = 500mV (Typ.)
8. Vos is defined as indicated bellow.
