Panasonic Patents Image Sensor for Full-Resolution Light Field Recording

Panasonic Patents Image Sensor for Full-Resolution Light Field Recording Today’s light field technology is facing a trade-off: The more depth resolution you want, the smaller the effective image becomes. Two years ago, German light field specialist Raytrix introduced a light field camera with an effective image resolution of 25 % the sensor’s resolution, which was already a big step upward.
Now, Panasonic has been granted a patent titled “Light field image capture device and image sensor”, which details a new sensor system that records light fields at 100 % of the sensor resolution.

HTC One M8: the World’s First Dual Camera Smartphone with Dedicated Depth Sensor?

HTC One M8: the World's First Dual Camera Smartphone? (picture: HTC) Last week, HTC unveiled the much anticipated, new HTC One M8, which immediately started selling in the UK, and will roll out across Europe, the Middle East and Africa, on April 4.

As rumoured, the new Android smartphone features a dual camera system (dubbed “Duo Camera”), where the additional camera is a dedicated depth sensor. To our knowledge, it’s the first time this technology has made it into a commercially available smartphone. The recorded depth information is used to bring a range of new camera features to HTC’s new flagship smartphone:

  • UFocus: Tap to refocus
  • Foregrounder: Apply filters (Pencil Sketch, Zoom Blur, Cartoon, Black&White) to the background.
  • Dimension Plus: Tilt your phone to change the perspective/distortion
  • Seasons: Add foreground-background-aware animations (falling rose petals, floating dandelion seeds, maple leaves, or snow)

Lytro Meltdown Update: Viewer 2.0 and Communicator with New Features

Lytro Meltdown Update: Viewer 2.0 and Communicator with New Features A few days ago, Jan Kučera released updates to both the Lytro Compatible Viewer and Lytro Compatible Communicator, bringing a range of new viewing options to the earlier, and wireless LFP download to the latter.

The author summarizes what’s new:

The wave of major updates finishes with a new release of the viewer. It now renders sub-aperture, epipolar and raw squared views that can also be exported. The sub-aperture images can be laid each over other to achieve subtle refocus effect. The precision improvements and usage of all microlenses should lead to noticeably better previews. Overall stability, especially when dealing with invalid files, was also improved.
This comes with a small update to the communicator as well, allowing you to generate LFP files from the camera over Wi-Fi, so you no longer need to connect it over USB to get your pictures.

Complete changelogs and download links after the break: Continue reading

Tesseract: Light Field Photography, Automated Subject Extraction and 3D Filters for your Smartphone

Tesseract Logo Remember Focii? The innovative light field capture method, developed by Kshitij Marwah at MIT Media Lab, allows users to convert ordinary cameras into light field cameras just by placing a coded mask film on top of the image sensor. Marwah has successfully ported Focii to a smartphone, and recently launched Tesseract Imaging to make the technology commercially available.
In a recent presentation at INKtalk, Kshitij Marwah presented the new product, and demonstrated three features on his modified Android smartphone (details below), live on stage: Continue reading
