PI201M-A4 Datasheet, PDF (4/6 Pages) AMI SEMICONDUCTOR – 200DPI CIS Sensor

(5) Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the nonuniformity percentage pixel to pixel
(6) Ud = Vdmax - Vdmin
Vdmin is the minimum output on a black document(O.D.=0.8)
Vdmax: maximum output voltage of black document (O.D.= 0.8)
(7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 4.0 lp/mm
Vmin: minimum output voltage at 4.0 lp/mm
(8) lp / mm: line pair per mm
(9) O.D. Optical Density
Switching Characteristics (25⁰C)
