PRNU (1) = Dc ´ 100 (%) c When ? is average of total signal output and Dc is the maximum deviation from ? . The amount of incident light is shown below. www.datasheet4u.com Red = 1/2・SE Green = 1/2・SE Blue = 1/4・SE Note 4: PRNU (3) is defined as maximum voltage with next pixel, where measured 5% of SE (typ.). Note 5: Image lag is defined as follows. Note 6: VSAT is defined as minimum saturation output of all effective pixels. Note 7: Definition of SE SE = VSAT (Ix × s) RG Note 8: VDRK is defined as average dark signal voltage of all effective pixels. DSNU is defined as different voltage between VDRK and VMDK when VMDK is maximum dark signal voltage. Note 9: DC signal output voltage is defined as follows. Reset noise voltage is defined as follows. 4 2002-12-25 TCD2558D Note 10: Random noise is defined as the standard deviation (sigma) of the output level difference between two adjacent effective pixels under no illumination (i.e. dark conditions) calculated by the following procedure. www.datasheet4u.com 1) 2) 3) Two adjacent pixels (pixel n and n + 1) in one reading are fixed as measurement points. Each of the output level at video output periods averaged over 200 ns period to get V (n) and V (n + 1). V (n + 1) is subtracted from V (n) to get DV. DV = V (n) - V (n + 1) 4) The standard deviation of DV is calculated after procedure 2) and 3) are repeated 30 times (30 readings). DV = 5) 6) 1 30 å | DVi | 30 i = 1 s= 1 30 2 å (| DVi | - DV ) 30 i = 1 Procedure 2), 3) and 4) are repeated 10 times to get sigma value. 10 sigma values are averaged. s= 1 10 å sj 10 j = 1 7) I value calculated using the above procedure is observed 2 times larger than that measured relative to the ground level. So we specify random noise as follows. NDs = 1 2 .
