About

MetaHammer is about tools and resources with impact. A metahammer is a script, a tool, a piece of software, an idea, or... anything... that has impact on what we do and on how we think.

If a picture is worth a thousand words….

When addressing technical problems, it’s often a paradigm shift that makes for the most compelling breakthroughs. PiCam is an experimental new micro-camera array from Pelican Imaging intended to be used on mobile devices. It provides high resolution images by using an array of tiny lenses instead of one large one. Think about radio telescope arrays and how they are able to gather celestial data much more efficiently than a single large instrument. With PiCam, you have an array of 12 lenses, each gathering information on an isolated sensor. The red, green, and blue spectra are gathered separately, with 4 sensors each. With such small lenses, the focal length is reduced and depth of field becomes nearly infinite.

Then the magic happens as the software combines the images buy kamagra oral jelly canada. What makes this compelling is parallax. You would think having multiple lenses would cause image degradation due to the fact that each lens is looking at the subject from a slightly different angle. But the engineers are using the parallax to create a depth map from the parallax data. Almost like using a stereo camera. So not only does the software correct for angles, they it can do it selectively according to the distances of the various surfaces in the scene. Among the side benefits of this process are both 3D views and user-variable depth of field. Watch the video for a full explanation:
