The image of the flat non-textured plane is recorded as Flat Field Image. The result image is output as the subtracted image between Flat Field Image and Input Image.
Train Flat Field Image with the following procedures:
Set the flat non-textured plane in front of the camera.
Adjust the exposure time in order that the peak of the histogram is at the center of the histogram and the maximum value of the pixel is less than 255.
Click [Set] button to record [Flat Field Image]. After when Flat Field Image is trained, Flat Field Image displays in the image display and its histogram displays in the graph and the table.
Switch [Image Display Mode] to [Result Image].
Make sure that the uneven lighting is corrected in the result image.
