Notes:

(1)

Tint: line scanning rate or integration time. Tint is determined by the interval between two start pulses (SP).

(2)

f: main clock frequency also equals the video sampling frequency.

(3)

Video output level is controlled with an adjustment as well as integration time.

(4)

Up = {[Vp(max) –Vp(min)]/Vp(max)}x100%

Where VP(max) = maximum peak pixel and VP(min) = minimum pixel.

(5)

Ud = Vdmax – Vdmin

Vdmin is the minimum output voltage with LED off.

Vdmax is maximum output voltage with LED off.

(6)

This level is measured from the reset level, which is located between the pixels, during the pixel reset duration. The reset level is at ground, 0V. It can be adjusted

with the offset potentiometer located on the module.

(7)

MTF = [(Vp(n) – Vp(n+1)] / (Vp(n)+ Vp(n+1)] x 100 [%]

Vp(n): n

V(n+1): (n+1)
