Working on a machine vision project requires understanding each part of the system, including light sources, frame grabbers, and computers. Here is a primer on two essential machine-vision terms.

Extended depth of field imaging systems represent a significant advancement in optical design, enabling sharp imaging over a broader range of distances. By incorporating methods such as wavefront ...

Put simply, depth of field refers to how much depth in your image is in focus. If objects both close to and far away from he camera are sharp, then you have a deep depth of field. If the foreground or ...

"What type of camera are you using? A small digital pocket-style or a larger DSLR with interchangeable lenses? This is important because getting a narrow DOF and blurred background is dependant on ...

I’m going to be using an imaginary lens of F4-F22 here for this discussion. It’s important to understand how the aperture works on your camera, but don’t get too obsessed in it. Think of the aperture ...

Lexy was a producer and on-air presenter who covered consumer tech, including the latest smartphones, wearables and emerging trends like assistive robotics. She won two Gold Telly Awards for her video ...

If you have a newer smartphone, then it likely came with the ability to shoot 3D images, or at least images with some depth of field involved. Making that happen requires your phone to have two ...

One of the most striking differences between your iPhone and a large camera like a DSLR is the way the two cameras focus and control depth of field. In a DSLR, depth of field is easy to manage by ...

Professional photographers use depth of field effects to keep one part of a photo in focus while blurring everything else, but you can also use image-editing software to do this when creating images ...

Our approach to extending the depth of field utilizes the concept of point spread function (PSF) engineering to greatly increase the axial range clearly imaged in a single exposure. The basic concept ...
