The exposure starts at the rising edge of the EXPOSE POS signal (or the falling edge of the
EXPOSE NEG signal). The exact exposure end point is on the preceding of the falling edge of the
EXPOSE POS signal in the range of maximum 1.11 micro seconds from the falling edge (referred to
below as exposure uncertain interval). The position of the point varies according to the integral of
the quantity of light input on the exposure indefinite interval. The relation between the light input and
the output of the camera is non-liner during the exposure uncertain interval. The red diagonal areas
on the following timing chart show the exposure uncertain intervals.
