The plenoptic function is a ray‐based model for light that includes the colour spectrum as
well as spatial, temporal and directional variation. Although digital light sensors have greatly …

A number of computational imaging techniques are introduced to improve image quality by
increasing light throughput. These techniques use optical coding to measure a stronger …

In recent years, several cameras have been introduced which extend depth of field (DOF) by
producing a depth-invariant point spread function (PSF). These cameras extend DOF by …

a-Si (amorphous Silicon) microbolometer FPAs (Focal Place Arrays) with TEC-less (without
Thermo-Electric Cooler) and shutterless capabilities have become the technology of choice …

Over the last decade, a number of computational imaging (CI) systems have been proposed
for tasks such as motion deblurring, defocus deblurring and multispectral imaging. These …

A number of cameras have been introduced that sweep the focal plane using mechanical
motion. However, mechanical motion makes video capture impractical and is unsuitable for …

Recently, several camera designs have been proposed for either making defocus blur
invariant to scene depth or making motion blur invariant to object motion. The benefit of such …

Two or more images are taken wherein during the image taking a focal sweep is performed.
The exposure intensity is modulated during the focal sweep and done so differently for the …

For centuries, cameras were designed to closely mimic the human visual system. With the
rapid increase in computer processing power over the last few decades, researchers in the …

For small camera modules in consumer applications, such as mobile phones or webcams,
size and cost are important constraints. An autofocus system increases both size and cost …
