Immervision has announced real-time video distortion correction software to help create professional quality videos on smartphones. The Montreal company also revealed an off-the-shelf 125-degree wide-angle lens, enabling mobile phone makers to improve their next-generation smartphone cameras.
The software algorithms are now available for mobile phone makers to license from Immervision’s exclusive distribution partner Ceva and promise to enhance images through artificial intelligence and machine learning.
The wider field of view (FOV) in phones creates more apparent distortion than you would see with other cameras. But the software algorithms from Immervision help correct stretched bodies and can adjust proportions — of objects, lines, and faces — in real time. The AI can take a line that looks like a banana and straighten it out, said Alessandro Gasparini, executive vice president of operations and chief commercial officer at Immervision, in an interview with VentureBeat.
Whether the goal is to leave the preset as is, fully customize it, let end users decide, allow phone orientation to dictate, or leverage machine learning to control the result, Immervision said it can help phone makers differentiate their hardware.
Gasparini said the algorithms offer real-time distortion correction in both videos and pictures, adjusting the perspective, capturing more of a scene with less distortion, and correcting line and object distortion.

While the majority of tier one phone makers have wide-angle lenses in their phones, tier two and tier three mobile brands have yet to adopt them. Immervision’s technology has been preconfigured on popular sensors, including Sony, Omnivision, and Samsung, and has one lens with ready-to-use software, reducing camera customization and integration time. The lens is 6.4 millimeters high and ranges from eight megapixels to 20 megapixels in terms of image quality.
“We design lenses for the mobile industry, with action cameras and broadcast cameras of different sizes, different resolutions, and different field of views,” Gasparini said.
Immervision surveyed users to find out what kind of image quality and distortion issues mattered most. Some lenses with low FOV numbers can make people on the edges of photos look fatter than they are, and that really makes people mad, Gasparini said. Most smartphones have lenses that are 100 to 130 degrees FOV. Immervision’s competition in this market includes Apple and Samsung, which do their own work. But Immervision aims to arm the rest of the industry with the same kind of high-quality cameras.

Gasparini said Immervision specializes in a combination of optical design and image processing, with different types of engineers under the same roof.
“We find ourselves to be one of the largest independent optical design firms in the world,” he said. “If you look at some of the companies that manufacture optics today for smartphones, they might have one or two optical designers in their factory. Actually, we have more, and we have cross-pollination of different competencies in our company.”
Immervision was founded in 2000 and employs around 30 people. Gasparini said the company has managed good profit margins as it works to help cameras better reproduce reality.
“Software can do certain magic on images. But there are limitations,” Gasparini said. “And there are challenges the next generation has dealing with more video. The new smartphones are cinematographic, and more people will be shooting short films and movies with them. This will increase the challenge of processing them in real time.”
