Electrooptical Characteristics (Note 1)
(Ta = 25°C, VDD = 12V, fφRS = 1MHz, Input clock = 5Vp-p, Light source = 3200K, IR cut filter CM-500S (t = 1.0mm))
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-G= 500mV (Typ.)
PRNU = × 100 [%]
Where the 5340 pixels are divided into blocks of 100, the maximum output of each block is set to V
MAX, the
minimum output to V
MIN and the average output to VAVE.
4. Use below the minimum value of the saturation output voltage.
5. Saturation exposure is defined as follows.
SE =
Where R indicates R
R, RG, RB, and SE indicates SER, SEG, SEB.
6. Optical signal accumulated time τint stands at 5.5ms.
7. VOUT-G = 500mV (Typ.)
8. Vos is defined as indicated below.
VOUT indicates VOUT-R, VOUT-G and VOUT-B.
