Motion Blur Photography and Shutter Speed
What is Motion Blur?
Motion blur is related to exposure. If the camera shutter length / exposure length is long relative to object speed, either linear and/or angular blur can occur.
What does Motion Blur do?
Motion Blur make objects in images look blurry, for both humans and for computers.
Exposure Has a Major Impact on Computer Vision and Machine Vision
Pei et. Al show how motion blur degrades the performance image classification. They show that VGG and Alexnet are more effected by angular motion blur than blur length, but both jointly degrade performance.
Avoiding Motion Blur is important to all computer vision tasks!

Trying to Determine Your Camera Requirements?
Use our free web-based AoV Calculator to determine your system's Field of View Requirements. Then, use the M12 Lens calculator to match your requirements with the available lenses. Our Depth of Field Calculator also provides the hyperfocal distance and depth of field for every sensor and lens combination.
We also have a couple of other calculators that many engineers find interesting.
