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 = (VMAX – VMIN)/2 VAVE × 100 [%]
Where the 5340 pixels are divided into blocks of 100, the maximum output of each block is set to VMAX, the minimum output to VMIN 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 = VSAT R
,
VOS GND
Where R indicates RR, RG, RB, and SE indicates SER, SEG, SEB. 6. Optical signal accumulated time τint stands at 5.5ms. 7. VOUT-G = 500mV (Typ.) VOUT 8. Vos is defined as indicated below. VOUT indicates VOUT-R, VOUT-G and VOUT-B.
