The Minoru 3D Webcam is a stereoscopic webcam by Promotion and Display Technology of Salford, Greater Manchester. Released in January 2009, it won the "Fans Favorite" award at the Consumer Electronics Show in Las Vegas. According to the company, it is the "world's first consumer 3D webcam." It was designed by David Holder.
The webcam, which hooks to a computer via a USB port, consists of two cameras "roughly the same distance apart as human eyes" are held together in a device that resemble Wall-E in appearance. It is capable of 3D, 2D, and Picture-in-picture. Its image can be output from 320x240 pixels to 800x600 pixels and it has a frame rate of 30 frames per second. The 3D imagery can be produced in anaglyph and side by side format.The camera has 2 x VGA 640x480 CMOS sensors, 2 x High quality wide angle lens, and a built in USB microphone.

4. Read the text and translate it: TV Goes Digital
The term "digital TV" is used in many different ways right now, depending on whom you're talking to. There's also the term "HDTV," which is the most advanced form of digital TV in use in the United States. The reason it gets confusing is because digital TV in the United States combines three different ideas.
The first idea that is new to digital TV is the digital signal. Analog TV started as a broadcast medium. TV stations set up antennas and broadcast radio signals to individual communities. You can attach an antenna to your TV and pick up channels 2 through 83 for free. Digital TV started as a free broadcast medium as well. For example, in San Jose, Calif., you can tune in to about a dozen different commercial digital TV stations if you have a digital TV receiver and an antenna broadcasts, so until the digital transition is complete, each broadcaster has an analog TV channel and a digital TV channel. The digital channel carries a 19.39-megabit-per-second stream of digital data that your digital TV receives and decodes. Each broadcaster has one digital TV channel, but one channel can carry multiple sub-channels if the broadcaster chooses that option.
Here's how it works: On its digital channel, each broadcaster sends a 19.39-megabit-per-second (Mbps) stream of digital data. Broadcasters have the ability to use this stream in several different ways. These streams are called sub-channels, and this type of broadcasting is called multicasting. The reason that broadcasters can create sub-channels is because digital TV standards allow several different formats. Broadcasters can choose between three formats.
(The "p" and "i" designations stand for "progressive" and "interlaced." In a progressive format, the full picture updates every 60th of a second. In an interlaced format, half of the picture updates every 60th of a second.)
The 480p and 480i formats are called the SD (standard definition) formats, and 480i is roughly equivalent to a normal analog TV picture. When analog TV shows are upconverted and broadcast on digital TV stations, they're broadcast in 480p or 480i.
The 720p, 1080i and 1080p formats are HD (high definition) formats. When you hear about "HDTV," this is what is being discussed -- a digital signal in the 720p, 1080i or 1080p format.
Finally, the HD formats of digital TV have a different aspect ratio than analog TVs. An analog TV has a 4:3 aspect ratio, meaning that the screen is 4 units wide and 3 units high. For example, a "25-inch diagonal" analog TV is 15 inches high and 20 inches wide. The HD format for digital TV has a 16:9 aspect ratio.
Many countries are replacing over-the-air broadcast analog television with digital television to allow other uses of the radio spectrum formerly used for analog TV broadcast. Digital television supports many different picture formats defined by the combination of size, aspect ratio and interlacing. There are a number of different ways to receive digital television. One of the oldest means of receiving DTV is using an antenna. DTV images have some picture defects that are not present on analog television or motion picture cinema, because of present-day limitations of bandwidth and compression algorithms such as MPEG-2. This defect is sometimes referred to as "mosquito noise". Because of the way the human visual system works, defects in an image that are localized to particular features of the image or that come and go are more perceptible than defects that are uniform and constant. However, the DTV system is designed to take advantage of other limitations of the human visual system to help mask these flaws, e.g. by allowing more compression artifacts during fast motion where the eye cannot track and resolve them as easily and, conversely, minimizing artifacts in still backgrounds that may be closely examined in a scene (since time allows).
