University of Toronto, a world-leading research university, announces a breakthrough development in video camera design. The Omni-focus Video Camera, based on an entirely new distance-mapping principle, delivers automatic real-time focus of both near and far field images, simultaneously, in high resolution. This unprecedented capability can be broadly applied in industry, including manufacturing, medicine, defense, security — and for the consumer market.

Inventor and principal investigator of the Omni-focus video camera, Professor Keigo Iizuka of The Edward S. Rogers Sr. Department of Electrical and Computer Engineering, explains that, “the intensity of a point source decays with the inverse square of the distance of propagation. This variation with distance has proven to be large enough to provide depth mapping with high resolution. What’s more, by using two point sources at different locations, the distance of the object can be determined without the influence of its surface texture.” This principle led Professor Iizuka to invent a novel distance-mapping camera, the Divergence-ratio Axi-vision Camera, abbreviated “Divcam,” which is a key component of the new Omni-focus Video Camera.

The Omni-focus Video Camera is produced in collaboration with consulting investigator Dr. David Wilkes, president of Wilkes Associates, a Canadian high-tech product development company. It contains an array of color video cameras, each focused at a different distance, and an integrated Divcam. The Divcam maps distance information for every pixel in the scene in real time. A software-based pixel correspondence utility, using prior intellectual property invented by Dr. Wilkes, then uses the distance information to select individual pixels from the ensemble of outputs of the color video cameras, and generates the final “omni-focused” single-video image.

“The Omni-focus Video Camera’s unique ability to achieve simultaneous focus of all of the objects in a scene, near or far, multiple or single, without the usual physical movement of the camera’s optics, represents a true advancement that is further distinguished in terms of high-resolution, distance mapping, real-time operation, simplicity, compactness, lightweight portability and a projected low manufacturing cost,” says Dr. Wilkes.

The resulting image shown in Figure 1a (taken with a prototype using two-color video cameras) clearly demonstrates how the omni-focused output dramatically differs from that of a conventional camera, shown in Figure 1b. Note that in the omni-focused image, the fingers in the foreground are so sharply focused that even the fingerprints are easily recognized.

Figure 2 illustrates the Omni-focus Video Camera’s high pixel resolution. Although the two sewing needles were photographed approximately 1.2 meters apart, both are in sharp focus. Note the eye of the back needle, is actually viewed through the eye of the front needle.

The camera is still in the research phase. But it’s not difficult to imagine how far-reaching an impact the Omni-focus Video Camera could have on several industries. As for the future direction of his research, Professor Iizuka sees the following possibilities:

(1) Application of the Omni-focus Video Camera to TV studio cameras. Consider the example of a musical concert being televised by a major network. Even though the singer is in sharp focus, band members in the background, are invariably out of focus. Conventional video cameras are unable to focus simultaneously on both the singer and band members in the background. The Omni-focus Video Camera removes this limitation to deliver higher-quality video images and improved quality of experience to potentially millions of TV viewers, worldwide.

(2) Application of the Omni-focus Video Camera to medicine. Says Professor Iizuka, “I’d like to apply the principle of the Omni-focus Video Camera to the design of a laparoscope. It would help doctors at the operating table, if they can see the entire view without touching optics of the laparoscope, especially if dealing with a large lesion.”

TORONTO, ON – With infrastructure spending a big part of government economic stimulus plans across North America, concrete is suddenly looking like a hot commodity. The University of Toronto’s Faculty of Applied Science and Engineering is at the forefront of innovation when it comes to concrete, sustainability and engineering solutions to some of the world’s most pressing issues. Now, one of our top professors has received recognition from the industry and the federal government.

R. Doug Hooton was appointed today Chairholder of the Natural Sciences and Engineering Research Council (NSERC) of Canada/ Cement Association of Canada Industrial Research Chair in Concrete Durability and Sustainability.

“Industrial Research Chairholders have to be outstanding researchers, able to build and nurture successful relationships with their industrial partners,” says Suzanne Fortier, president of NSERC. “Dr. Hooton is an excellent example of this blend of talent and skills. The Canadian cement and concrete industries will benefit greatly from his research goal to produce stronger, higher quality building materials.”

The Chair’s funding is valued at $1.8 million over five years with contributions from the University of Toronto, NSERC, the Cement Association of Canada, Holcim Canada and Whitemud Resources. The financial award will create a new tenure-track faculty position in this area and also allow for funding graduate student and research associate positions.

The goal of the Research Chair is to provide innovative and effective approaches to improve both the environmental sustainability and durability of concrete, as well as to provide leadership in development of specifications and industry standards. Enhancing the durability of concrete, while incorporating recycled local materials, improves the sustainability of buildings and infrastructure.

“This Chair will help focus research and teaching in an area that is critical to making informed choices in infrastructure renewal and addressing the environmental and energy sustainability challenges facing the cement, concrete and construction industries,” said Dr. Hooton. “This area is of utmost importance to the Canadian cement industry and to Canadian industry and infrastructure as a whole, and I want to thank NSERC and the industrial partners for their commitment, even in tough economic times.”

Attendees at the event

Some of Professor Hooton’s discoveries in the chemical degradation of concrete by alkali-silica reaction and in the rate of penetration of de-icing salts leading to corrosion of steel in concrete bridges have been adopted by the Ontario Ministry of Transportation as well as in Canadian (CSA) and US (ASTM) standards. He is also using sophisticated nanotechnology level tools to examine the chemistry and mineralogy of concrete and to investigate its durability. He also hopes to use ‘particle packing’ down to the nano level to make what he calls “quantum leaps” in the properties and durability of concrete.

“Professor Hooton is a leading innovator in the important field of sustainable concrete engineering and cement research,” said Cristina Amon, Dean, Faculty of Applied Science and Engineering. “We are grateful to NSERC and our industrial partners for enhancing our efforts to address concrete sustainability and its environmental implications in the infrastructure renewal.”
