Parallax Correction: Using the Camera at Non-
Perpendicular Angles to the Object
When using a Linea Lite color camera at an angle to the objects surface, the object pixel size for
the red-blue and green pixel arrays are slightly different. This is due to parallax. If the camera
angle and the lens angular field of view are sufficiently large, this may cause color artifacts at the
extremities of the image. The color camera includes a Parallax Correction Pixel Stretch
feature that
can correct these color artifacts.

Notes:
• This feature will be most useful when processing RGB image formats using 4K cameras with
long focal length lenses.
• Parallax correction of the individual colors cannot be performed due to the row summing in
the sensor. Therefore, at high angles, a degradation in MTF at the end pixels may occur.
• Selection of the color to adjust is dependent on positive or negative angle. It is not sensitive
to scan direction.
• The stretch value for green is always half that of the stretch value for red-blue.
