I am trying to image some ChArUco targets using a monochrome machine vision camera with a CMOS sensor and the attached images show the artifact I am observing:
2-pixel-wide bright vertical streaks adjacent to light-to-dark edges (only on light-dark transitions from left to right).
Here is another example where the white-to-black edge is nearly vertical, and the contrast is higher.
The "ghost shadow" of the edge is less perceptible but still there
Any ideas as to the cause and remedy?
I have tried changing the camera's gain, exposure time, lens aperture etc. But, all these settings do is change image exposure and contrast, which can mask the effect, but not eliminate it (as in the 2nd example image).
I have received some guidance suggesting the streaks may be caused by the over-exposure and saturation of the white regions. I will try and reduce the exposure...
