Definition:

1.

Tint: line scanning rate or integration time. Tint is determined by the interval of two SPs.

2.

Freq is the main clock frequency.

3.

Vpavg =

∑ Vp(n)/1728

4.

Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%

5.

Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%

Upadj is the non-uniformity percentage of adjacent pixels

6.

Ud = Vdmax – Vdmin

Vd is the voltage amplitude between the output video's reset level and its dark level.

Vdmin is the minimum output with LED light off.

Vdmax: maximum output voltage with the LED light off

7.

MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]

Vmax: maximum output voltage at 4.0lp/mm

Vmin: minimum output voltage at 4.0lp/mm

8.

lp / mm: line pair per mm
