Sony demos 3D display prototype

Hi! Very interesting! Or at the very least it's a lot more interesting than the current crop of 3D technologies needing glasses and whatnot.

If you salivate at the thought of 3D displays, but don't like wearing those dorky glasses, then Sony's latest prototype might be just up your street.

The display, which is due to be demonstrated at Japan's Digital Content Expo this Thursday, can be seen over at Impress (Babelfish translation), and it's certainly a departure from the norm.

Rather than a traditional flat screen, the 13 x 27cm cylinder looks more like a stylish desktop water cooler than a display. However, at the heart of the device is a wraparound OLED display that shows an image that can be viewed from any angle - in true 3D. This makes it very different from standard 3D displays that project a 3D picture via anaglyph images or polarising filters.

Sadly, the resolution is currently far from high definition standards: although the little figure is presented in glorious 24-bit colour, it's a mere 96x128 pixels in size (0.12 megapixels), so it's not exactly photo-realism.

That said, the device is clearly a prototype, and a smart one at that. Sony reckons the device will be handy for anyone who needs to work with three dimensional objects, such as those in the medical imaging market. What's more, it will also have the obvious "cool" factor that could see it being snapped up as a neat 3D photo frame - as long as someone releases a decent 3D camera, that is.

A video of the device is available on Sony Japan's website, although the true test of the gadget will of course be the public demonstration on Thursday.

Does Sony's latest wheeze looks like the 3D display you've always wanted, or does the technology have a long way to go before products such as this will be genuinely marketable? Share your thoughts over in the forums.

Japanese Students Create 3D Version of Destroyed Neighborhood

Hello to you

I was surfing the Net and found the article about very touching act. I think these guys deserve to be proud if.

Students at Japan's University of Nagasaki are attempting to recreate a neighborhood an atomic bomb destroyed. Seventy thousand people died when the United States dropped an atomic bomb on Nagasaki to end World War II. Pictures and memories of the Urakami neighborhood at the city's center vanished with them. But a 3D project is bringing the neighborhood back to life.

University of Nagasaki professor Byondok Jun's vision to recreate the city's Urakami neighborhood began with one image: an aerial photo of Nagasaki, taken by a U.S. warplane.

The image was snapped two days before the U.S. dropped an atomic bomb on the city near the end of World War II. But it was only released a few years ago. The black and white image captured a hospital, the university and surrounding homes; all buildings that were destroyed on August 10, 1945.

Jun says the image brought back the trees, the laughter, the city that existed before the attack. It gave him the first glimpse into life in Urakami and inspired him to recreate a three-dimensional image of the neighborhood.

Jun only planned to complete the aerial image - but students Yurika Uchijima and Kanouko Maeda asked to take the project a step further. They wanted to recreate street corners and store fronts - making the images more personal - for their graduate thesis.

Maeda says they had no idea where to start. They studied the professor's 3D aerial image first. Then they set out in search of old pictures of the Urakami neighborhood.

There was one problem: most photos of the community were destroyed in the attack. With few images to draw from, Maeda and Uchijima went in search of atomic bomb survivors and relied on their descriptions of Urakami.

Eighty-year-old Yoshitoshi Fukahori heard about the project and agreed to help out.

Fukahori says some question why I did this for free. But I felt an obligation to share my story as an atomic bomb survivor.

Fukahori was a teenager in 1945. He describes the Urakami neighborhood as one big family that opened its doors to everybody. He recalls the community gathering at the local barbershop to celebrate the smallest accomplishments and share in each other's joy.

In the early 1940s, Japan had conquered much of Asia and was at war with China, Britain and the United States. To end the war in August 1945, the United States dropped the first atomic weapons ever used on the cities of Hiroshima and Nagasaki. A few days later, Japan surrendered.

Fukahori was not home the day of the bombing but his sister was.

He says he found her dead a few days later. She was grasping the beam of their home. His uncle was crushed under the building and his aunt died as well.

Fukahori has spent the past 30 years collecting pictures of his old neighborhood for Nagasaki's Foundation for Peace.

Now those pictures are the foundation of a project to bring his memories back to life.

Student Yurika Uchijima says Fukahori pointed them to the playgrounds and a well where neighborhood children gathered to relax. She says he put a personal story behind every one of the buildings.

The students have used those stories and the few pictures available to recreate 3D images of more than a tenth of Urakami's building. They hope to complete the project by December. Uchijima and Maeda do not have any idea how their images will be used after that but professor Jun sees it as a tool for peace, one that teaches another generation about the power of a nuclear weapon.

Fujifilm Brings 3D Still Camera to the US

Hello! The new technique in US.

Fujifilm’s Real 3D W1 camera doesn’t throw the term “3D” around lightly. It actually creates three-dimensional still and video images, and prints them out on special paper. Here’s how it works: The camera has two sensors and two lenses, and Fujifilm’s Real Photo 3D processor combines them into a single image. On the back of the camera, a special monitor controls the direction of light sending different images into each eye, so you can preview the 3D stills without special glasses. Special paper basically mimics this concept, laying the image onto a “lenticular sheet” that creates a different angle of view for each eye.

In addition to the automatic 3D photography, the 3D W1 has a few advanced photo modes, allowing you to snap shots at different angles or at different time intervals, creating a greater illusion of depth. And while previewing the photos, you can actually control the parallax effect that separates foreground and background images.

Gimmicky? Sure, so it’s helpful that the 3D W1 also lets you shoot in tried-and-true 2D. The image sensor has 10 megapixels, and the lens zooms to 3x. Bundled software converts 3D images into 2D. There’s no exact word on availability asking price will be around $600.
