Linear Optical Technology

Because distortion correction is done in the lens optically, no additional dewarping software or hardware is required. Images appear more natural and have greater resolution compared to lenses with barrel distortion such as fisheye lenses. With a fisheye lens, not only are there unilluminated pixels on the sensor (illuminating only about 2/3 of a 3 megapixel sensor) but the image gets compressed at the edges. Theia's rectilinear lens actually increases the object size closer to the image edges.

Comparison of Theia's low distortion lens to a fish eye lens with distortion

Another comparison showing straight lines (such as lights and the balcony railing) remain straight in the image.
