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.
Pelican Imaging has recently released a short video where CEO Chris Pickett explains what’s so interesting about light field photography:
In the 2-minute clip, Pickett explains how Pelican’s Array Camera works, and shows its most exciting features: software refocus, multiple focus (focus on several depths in one image), segmentation (automatic depth-based object extraction). Continue reading →
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)
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.
