Sony Develops High Frame Rate Single Lens 3D Camera Technology



High Frame Rate Single lens 3D (prototype) camera captures natural and smooth, high quality 3D images at 240fps


Sony press release:


Sony Corporation today announced the development of a single lens 3D camera technology capable of recording natural and smooth 3D images of even fast-moving subject matter such as sports, at 240fps (frames per second). This technology combines a newly developed optical system for single lens 3D camera which captures the left and right images simultaneously, together with existing high frame rate (HFR) recording technology to realize 240fps 3D filming. Sony will demonstrate a prototype model incorporating this technology at “CEATEC JAPAN 2009”, to be held at Makuhari Messe convention center in Chiba city, Japan, from October 6th.

Optical system for single lens 3D camera














240fps 3D Filming

Optical tests have shown that a frame rate 240fps represents the limit of human visual perception, and beyond that it becomes difficult to detect differences in terms of blur and “jerkiness” of moving images (where images that were continuous are now seen as a series of distinct snapshots). By developing a 240fps frame rate CMOS image sensor with properties close to the human eye, which is capable of capture natural images of even fast moving subject matter, Sony has succeeded in further enhancing the quality of 3D video images.

The combination of Sony’s new single lens 3D system and its 240fps high frame rate technology has realized a single lens 3D camera system, based on universal properties of the human eye, which enables natural and smooth 3D images with no accommodation-vergence*1 conflict to be recorded.

Technological Features
1. New single lens optical system
- Captures left and right images simultaneously to deliver natural and smooth 3D images with no accommodation-vergence conflict.
- Eliminates the need for lens synchronization, ensuring easily accurate control of 3D zoom and focus functions.
- When polarized glasses are not used, viewers with still be able to see natural 2D images, as the disparity of the images for left and right eyes are within the range that human eyes can recognize as a blur.

2. 240fps image capture to realize high quality motion images
- Realizes high quality capture of 3D content including fast-moving subject matter such as sports.
Prototype to be demonstrated at “CEATEC JAPAN 2009”

Within the growing 3D cinema industry, Sony has supported and driven the expansion of 3D by providing a wide variety of professional equipment for the shooting, production and screening of movies in 3D. The number of digital 3D screens is increasing rapidly, and is expected to reach 7,000 worldwide by the end of 2009*2 In addition to 3D movies, Sony’s range of professional 3D products and technology is also driving the growth of 3D production and distribution across a range of entertainment industries, from theatre and music performances to sport and beyond. Furthermore, Sony is also aiming to continue to lead the way in delivering new 3D viewing experiences by bringing 3D to the home in 2010.

Hasselblad H4D-60 review

UPDATE 18 May, 2012: Hasseblad is set to reduce the price on the H4D cameras by as much as $11,000 / 6,200 Euros on the H4D-60, bringing the price to 23,900 euros ($30,995 / £21,995). Please see here for more details.

The last couple of decades have been turbulent for medium format camera manufacturers, but now after several well-known names have withdrawn, the market looks healthy. Two new unexpected entrants, Leica and Pentax have added to the dynamic at opposing ends of the pricing scale, forcing the two established system players to compete fiercely in their traditional rarefied role as well as the entry-level.

Partnering with both Leaf and Mamiya, Phase One has developed a trio of entry-level Mamiya DM models starting at under $14k/ £9k while continuing to offer a wide range of Phase One and Leaf backs, up to 80-megapixels. Through various offers and incentives these backs, are most likely to be partnered with the 645DF body but they are in fact compatible with a wide range of …

Fujifilm IS Pro UV-IR DSLR review

Fuji’s IS Pro is the up-date to maker’s earlier S3 UV-IR camera, and like that particular camera, the IS Pro adopts a modified image sensor that’s not shielded from UV or IR light. Consequently, with various filtration methods, the IS Pro is designed for Ultraviolet (UVA), visible and near Infrared photography.

Although there is a healthy demand for DSLRs with IR capability especially, and there are number of independent vendors (mainly in the US, but the UK also) that offer IR dedicated and full-spectrum conversion of current Nikon and Canon bodies, it’s anticipated the IS Pro will appeal largely to the scientific and forensic communities. With the departure of the S3 UV-IR, Fuji’s IS Pro continues to be the only dedicated full-spectrum interchangeable lens based DSLR that has professional-level support from a camera maker. As well as official product support and 12-month warranty, for government agencies and the like, the OEM status of the IS Pro will be particularly reassuring an…

Introduction


Unlike the process of dithering liquid ink in an inkjet, dye-sublimation printers produce authentic continuous tone images with an analogous look like that of a conventional lab-produced print. They achieve this using thin c…
