3.6.5 Clipping
If the gain and offset on one or more of the
lines in an L304
kc camera are set
incorrectly, “high clipping” or “low clipping”
can occur.
High clipping is caused when the
combination of gain and offset is set so
that the range of light level data in the
scene being captured by a line exceeds
the range of the line’s output. In this
situation, all of the pixels that are seeing a
light level higher than the line can
represent will be “clipped” at the line’s
maximum output value as shown in Figure
3-20.
Low clipping is caused when the
combination of gain and offset is set so
that a large part of the light level data in the
darker areas of scene being captured by a
line is below the range of the line’s output.
In this situation, all of the pixels that are
seeing a light level lower than the line can
represent will be “clipped” at the line’s
minimum output value as shown in Figure
3-21.
If the camera is experiencing clipping, a
clipping error flag will be set. You can
determine whether clipping is present by
checking the camera status as described
in Section 3.14.
