Invention – a moving base from Satarii that allows your camera to follow you
by Marshall Brain | February 11, 2011
This is a great idea, nicely implemented to make it simple. It is a base that allows your camera to automatically track you as you move around: This is not so conceptually unusual. For example, people have been making people-followers for awhile in the form of paintball sentries: Satarii has radically simplified the problem with [...]
The typical consumer digital camera offers 10 to 12 megapixels. Pro cameras tend to top out at about twice that – 24 megaixels or so, like this Nikon: 24 megapixels apparently isn’t enough however. Now there is an 80 megapixel camera from a company named Phase One: According to this article… Phase One pushes ahead [...]
In most cameras, you take a large image sensor (say 12 million pixels) and use those pixels to capture more detail across the X and Y axis of the image. What if you changed the lens on a camera so that it used all those pixels to capture more data about the Z dimension instead? That is the basic idea behind the plenoptic lens shown here…
This truly has to be one of the best attempts ever to take a product that is not selling and trying to find the right marketing niche for it…
An amusing comparison between the $1,800 Canon 7D and the $50 Barbie Video Girl: You can find a fair number of these comparisons if you look around. In the Canon vs. Barbie comparison the difference in image quality is obvious. In some of the others, it is harder to tell: Comparison between Canon 7D and [...]
Behold, the Frankencamera. It lets developers, hobbyists and experimenters play with camera components and algorithms to create new things: From the video’s description: Although there has been much interest in computational photography within the research and photography communities, progress has been hampered by the lack of a portable, programmable camera with sufficient image quality and [...]
This morning, FanStuff’s Tracy V. Wilson pointed out an article by Wired’s Priya Ganapati, in which she talks about a brand-new technology for digital camera image sensors. A California-based company named InVisage Technologies has created an image sensor that uses quantum dots rather than silicon as you’d find in the charged-couple device (CCD) or complementary silicon oxide semiconductor (CMOS) image sensors that predominate the digital camera industry.
While listening to the Skeptic’s Guide to the Universe podcast, I heard an amazing fact: scientists at the University of California had created a camera capable of taking 6.1 million pictures in a single second. Talk about high-speed photography!
A little research turned up this article by Brandon Keim from Wired. The camera uses a laser to illuminate the subject of the photograph. The scientists call the technology serial time-encoded amplified microscopy, or STEAM.
Here’s a breakdown of what happens when they use the camera: the laser runs through a series of 3,000 different wavelengths of light. Each wavelength corresponds to a specific pixel on the sensor of the camera. When the sensor detects the light reflected back to the camera from the subject, it matches each wavelength to the appropriate pixel. The camera sends a matching wavelength to the pixel to compensate for the lack of light.
Welcome to the first TechStuff Podcast Super Happy Fun Time Roundup (TechStuff Podcast Roundup for short). At the end of every week I’ll give a quick rundown on the episodes of TechStuff we just published. We’re following the lead of Josh and Chuck: podcast hosts, bloggers and senior writers extraordinaire!
This week on TechStuff, Chris and I tackled two very different topics. On Monday’s episode you’ll hear us discuss digital camera tips and tricks. Listen in to find out how you can take better shots with your digital camera. You’ll also get the chance to hear me wax rhapsodic about professional wrestling. I’m not sure why my go-to example always involves a match between John Cena and the Undertaker — I need to work CM Punk in there somewhere.
Wednesday’s episode saw us return to a topic that we’ve looked at several times before: computer viruses. But that’s not all…
