Compensate for barrel distortion
Barrel distortion is a phenomenon where straight lines appear increasingly bent closer to the edges of the frame. A wide field of view
often creates barrel distortion in an image. Barrel distortion correction compensates for this distortion.
Note
Barrel distortion correction affects the image resolution and field of view.
1. Go to Settings > Image > Image correction .
2. Turn on Barrel distortion correction (BDC) .
3. Use the slider to improve the image.
Verify the pixel resolution
To verify that a defined part of the image contains enough pixels to, for example, recognize license plates, you can use the pixel
counter.

3. In the camera’s live view, adjust the size and position of the rectangle around the area of interest, for example where you

You can see the number of pixels for each of the rectangle’s sides ( X and Y ), and decide if the values are enough for
your needs.
