4.11.2 White pixel · Black pixel correction data acquisition condition
◆
When acquiring white pixel correction data
Remove the lens cap to make the subject white uniform. Any white correction data
can be acquired with this. When the lens is attached, the shading of the lens and the
light source are corrected at the same time, but since the shading of the subject is
directly reflected, shift the focus.
◆
When capturing black pixel correction data
Please attach the lens cap and shade the light.
