Mirror Image - Basler A400K User Manual

3.10 Mirror Image

When the mirror image feature is enabled, the pixel values for each line will switch end-for-end
about the line's center point. If you use full resolution, on each line the value for pixel 1 will be
swapped with the value for pixel 2352, the value for pixel 2 will be swapped with the value for pixel
2351, the value for pixel 3 will be swapped with the value for pixel 2350, and so on.
The mirror image feature also works for AOIs. The swapping of pixel values is analogous to the
swapping at full resolution. On each line the value of the first pixel is swapped with the value of
the last pixel, the value of the second pixel is swapped with the value of the next-to-last pixel, and
so on.
Enabling/Disabling the Mirror Image
You can enable/disable the mirror image feature by using the Camera Configuration Tool Plus
(CCT+) or by using binary write commands from within your own application to set the camera's
control and status registers (CSRs).
With the CCT+
With the CCT+ (see Section 4.1), you use the mirror mode parameter in the Output parameters
group to enable or disable the mirror image feature.
By Setting CSRs
You can enable/disable the mirror image feature by writing a value to the Mirror Mode field of the
Mirror Image Mode CSR (see page 4-32).
See Section 4.2.2

Note
If you use the mirror image feature for a color version, remember to also
swap the assignments of colors (R, G, B) to the pixels (see Section 3.11)
by setting your frame grabber appropriately. If, for example, the original
sequence in a line was G, R, G, R, ... the new sequence in the same line
must be R, G, R, G, ...
Note
If you run a sequence of AOIs and if you have enabled the mirror image
feature, the mirror image feature will be applied to all AOIs.
