Panasonic 3D Full HD truck The problem with anaglyph 3D is that it strains the eyes, and can cause headaches and nausea in some people. Others have a dominant eye, and find it difficult to see the image as three dimensional.A newer process for 3D in the cinema uses a special screen and polarized glasses. In this system images for the left and right eye are rapidly alternated, and the glasses pick up the appropriate image for each eye. A similar technique has now been introduced for high definition LCD televisions by LG Electronics in South Korea and Hyundai in Japan. The system, known as X-Pol, projects the different images in the even and odd horizontal lines of the video, and the polarized glasses sort it all out for the viewer. The original 3D experience of movies depended on the viewer wearing stereoscopic green and red glasses. The illusion of 3D in the image came from superimposed green and red images taken from slightly different angles. Each eye saw only one image, and the viewer’s brain combined them to give the illusion of three dimensions. 3D movies using this technology, called anaglyph 3D, can be viewed on any TV, as long as the viewer wears the glasses. Panasonic executive Peter Fannon said the new high definition 3D televisions will give viewers an experience just like being there, rather than watching it on TV.Panasonic will be releasing some Full HD 3D models later this year, with Sony’s version coming on the market later. Buyers of the new TVs will also need 3D-compatible Blu-ray disc players. The glasses will be supplied with the TV sets. There is no information yet on the prices of these televisions.

LG Electronics 47LH50 3D LCD TV (PhysOrg.com) — Sony and Panasonic have recently announced a new technology, called “active shutter” for producing the experience of 3D on high definition TVs. The first models are expected to be available in late 2009 or early 2010.

By watching these images through special LCD glasses that are timed to open and close the right and left lenses in synchronization with the alternating images, the viewer is treated to exciting 3D realism. Image: Panasonic Now Sony and Panasonic have introduced an “active shutter” technique for high definition plasma and LCD TVs. The viewer still has to wear polarized glasses, but in this system the glasses have LCD active shutters that are synchronized with signals from the TV. The shutters rapidly block the right and left eye views alternately so each eye receives the correct image. The new system gives higher resolution than X-Pol because in active shutter technology each eye sees all the lines in the video, whereas in X-Pol each eye sees only half the lines.

Kolkata: A water treatment plant with capacity of 55 million gallon is coming at Uttarpara in Hooghly district.A review meeting to take stock of the work was held by state Municipal Affairs minister Firhad Hakim at the conference hall of Kolkata Metropolitan Development Authority (KMDA) on Tuesday. “The Palta water treatment plant came up before the Independence. Now Uttarpara is getting a water treatment plant which happens to be the largest in the state since independence. It will be responsible for supplying water in seven municipalities in Hooghly and about 10 adjoining panchayat areas. The supply line will be similar to that followed in Kolkata Municipal Corporation,” Hakim said after the meeting.

According to the chairman of Uttarpara Municipality, Dilip Yadav, work to develop the infrastructure for the water treatment plant such as laying of pipeline for water supply and construction of water tanks have started since five months. The complete work will take around two years. The estimated cost for the project is Rs 1,760 crore. “Work was delayed because of the Model Code of Conduct (MCC) that was in effect because of the elections. There were some problems regarding the contractor firm selected for executing the work. The minister not only took stock of the progress of work but also gave necessary instructions on how to speed up work,” an official of Uttarpara Municipality, who attended the meeting said.
