Sensors and Cameras

Interested in trying out plenoptic light field camera technology, but don't have access to a Lytro camera (or for that matter, a Toshiba sensor prototype)? The Chaos Collective has developed a free online tool that enables you to approximate the approach using a recent-model DSLR that's capable of capturing not only still images but also […]

Plenoptic camera technology, most commonly known nowadays by virtue of Lytro's ongoing promotion of the concept (and sales of the first-generation implementation), has received primary mainstream attention to date because the light field-based approach allows for post-capture selective focus on particular depth regions of an image. However, embedded vision advocates likely are alternatively intrigued by

Lytro's light ray-based plenoptic camera technology, which enables post-capture selective focus on any particular depth region of an image, has received periodic mention on this site. Back in October of last year, for example, I covered the cameras' initial unveiling. And more recently, BDTI engineers Eric Gregori and Shehrzad Qureshi discussed the underlying technology in

The image sensor is a key piece of any embedded vision system design, of course. As such, many of you are probably already familiar with the term "Bayer Pattern," which I discussed in some detail in a technical article published last fall. A Bayer Pattern sensor transforms the inherently monochrome light capture process into a
