LQ-401CL

Setting example:
Left side = -3 or 3
Area : 6, 2nd : 4, 3rd : 2
4096th Pixel
Fig. 24 Setting example
Note: 1) If left side pixel is set at -2 or +2, only Area and 2nd can be configured.
3rd cannot be set.
2) If left side pixel is set at -1 or +1, only Area can be configured.
Caution on calibration:
The object must be charts or materials which have clear and sharp discrimination of white and
black edges. The volume of color difference in peripheral area is measured by using the image
analysis software. Check how many pixels of R and B channels are shifted against G channel. In this
function, maximum three pixels are compensated.
For instance, if R channel is shifted 1 pixel to the left in the left end of the image, this means “-1”
and set the command CABLR to 1.
The compensation for the right side is automatically effected.
6.2.12 Aperture filter
LQ-400CL has a circuit for image enhancement in order to improve visible MTF. The compensation
coefficient is a fixed value and cannot be changed. The factory default for this function is OFF. This
function does not depend on the operating mode.
6.2.13 Binning
In this mode, the camera combines the charge collected in two adjacent pixels. This halves the
effective resolution to 2048 pixels, but doubles the sensitivity. The line rate is not affected by
binning. This function does not depend on the operating mode.
