For more than a hundred years, cameras have shared a frustrating limitation with human eyes: they can only focus on one ...

For more than a century, photographers have had to choose which part of a scene should be tack sharp and which parts would ...

The depth-defying lens can focus on multiple objects at different distances.

In photography, depth of field refers to how much of a three-dimensional space the camera can focus on at once. A shallow depth of field, for example, would keep the subject sharp but blur out much of ...

A new method allows nearly perfect optical sharpness for scenes requiring a wide depth of field, with just two photos.

In an image, estimating the distance between objects and the camera by using the blur in the images as clue, also known as depth from focus/defocus, is essential in computer vision. However, ...

“In optics, there was a problem,” says Amit Agrawal, a physicist at the National Institute of Standards and Technology in Gaithersburg, Md. If you wanted to focus a single lens to two different points ...

Researchers from Carnegie Mellon University's College of Engineering have proposed a new photography method that eliminates the need to choose between focusing on the foreground, midground, ...

The first thing to know about buying a digital camera in 2024 is that it's virtually impossible to buy a bad one. You probably have a great camera in your hand right now. For many people, a smartphone ...

The proposed method takes as input the focal stack and camera settings, and establishes a cost volume based on a lens defocus model. This design enables depth estimation with different camera settings ...
