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 the 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 on.
(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 or near ground, 0V. Note that
the gain is adjustable on each output. However, it is recommended that the gain should not be increased above the level where the reset ground level starts to
increase above zero.
(7) A graph of a typical MTF is shown in Figure 3.
