Charles Chi, a graduate of Ottawa's Carleton University who sold the optical networking company he founded, Lightera Networks, to Ciena Corp. for $ 452 million in the late 1990s, has re-emerged as chairman of Mountain View, Calif., company Lytro Inc. Lytro has developed a new method of taking pictures that can capture the angle, colour and placement of every ray of light within an image, producing a photo that is light years ahead of current photographic technology. The company says it will introduce a point-and-shoot camera with the new system this fall that will be priced in range of existing digital cameras. Current camera technologies break a two-dimensional image into tiny pixels and then assign each pixel to an address that allows the image to be recreated on a screen. The more pixels used to make the image, the sharper the image will be. But Lytro's technology makes pixel mapping technology look like a floppy disk. " It redefines the term megapixel," Chi said in an interview Wednesday. " What we are capturing now are rays. Rays are much more important than pixels. " The innovation here is being able to actually capture the light rays. The angle that the light came in, the power, the intensity, the colour. All those aspects. I think a lot of photographers are going to embrace this and learn a new way of taking pictures." Lytro says its cameras will be capable of taking images far faster than digital cameras can. They'll be better in lowlight situations, and the technology used to snap the image means every picture taken will be, by default, a 3-D image. As well, it promises photographers that they will never again produce an unfocused image. All the information needed to refocus an image will be stored in the image file and can be used after the picture is taken to sharpen the photograph. The technology, called light field photography, could advance picture-taking in the same way that digital cameras pushed photographers to give up their aged film-based cameras, its inventors say. " This is the next big evolution of the camera," said Ren Ng, founder and chief executive of Lytro. " The move to digital from film was extraordinary and opened up picture taking to a much larger audience. Now you can snap once and focus later to get the perfect picture." The technology started out as a research project in a Stanford University lab in the mid1990s. In 2005, Ng began working with the technology as part of his PhD studies at the Palo Alto, Calif., school. Until then, taking a photo that captured all the light rays within an image required hundreds of cameras hooked to a supercomputer. " This is a huge revolution, a very big change. I think as a company we can bring a lot to the table in terms of a product," said Chi. " It's a very large market. It doesn't take much of the market share for us to become a large, substantive, independent company." The company expects to begin selling its first point-and-shoot camera to American consumers later this year. An international launch will follow. Chi wouldn't say what the price of the new camera would be. But he said it would be " competitive" with more traditional digital camera prices.
