A stereoscopic vision system uses at least two cameras having different parameters to image a scene and create stereoscopic views. The different parameters of the two cameras can be intrinsic or extrinsic, including, for example, the distortion profile of the lens in the cameras, the field of view of the lens, the orientation of the cameras, the positions of the cameras, the color spectrum of the cameras, the frame rate of the cameras, the exposure time of the cameras, the gain of the cameras, the aperture size of the lenses, or the like. An image processing apparatus is then used to process the images from the at least two different cameras to provide optimal stereoscopic vision to a display.

Wide-angle stereoscopic vision with cameras having different parameters

A method for controlling an optical system including at least one active light-controlling element to better control the illumination of a scene when imaged on an image sensor is presented. This active light-controlling element is used to control the amount of light in an image zone depending on an electric signal from a controller. This allows imaging scenes with bright objects without over-exposure or scenes with dark objects without under-exposure on the image sensor. After image processing to reverse the effect of the active light-controlling element, the resulting processed images have an enhanced depth without the drawbacks associated to traditional HDR imaging. The method can use any shape of sub-elements in the active light-controlling element depending on the application. The method can also be used with multiple active light-controlling surfaces to further control the light on the image sensor, including separating the colors in the image.

Adaptive relative illumination optical system

A method for designing an optical system for providing reliable, robust and successful realization of a distortion variation function is presented. In a preferred embodiment, the proposed distortion variation optical system includes at least two non-symmetrical elements, which are moving in the transverse direction. The proposed freeform lens contains two transmissive refractive surfaces. The freeform elements designed with this method have preferably a flat surface and a non-symmetrical freeform surface. The two plano-surfaces are preferably made to face each other, so that a miniature camera can be offered. The value of the non-symmetrical freeform surface is used to produce variable optical power when the two freeform elements undergo a relative movement in the vertical direction. Using this method, an optical system with an active distortion, smaller form factor, and better imaging quality can be obtained.

Optical system with dynamic distortion using freeform elements

Systems and methods in accordance with the invention allow automatic recording, sharing, and communicating of different parameters associated with images and their imager to define a specific system behavior of a display device or an algorithm unit. Examples of information include imager parameters, environment parameters, image processing and enhancement parameters, coordinates of a section of wide-angle scene image content, display parameters, defined user experience, defined system behavior or any information to be recorded, shared, and communicated. To avoid loss of information, the information is encoded directly in the picture using a marker. This way, the information is robustly transferred from the imager to the display unit. According to the information, the final image can be automatically corrected and enhanced before display, different associated parameters can be displayed on final image or be used with another output. The end user experience or system behavior can thus be defined and be reproduced.

Automated identification of panoramic imagers for appropriate and efficient panoramic image distortion processing system

An image distortion transformation method for transforming an original image by an imager having an original distortion profile to a transformed image optimized for a distortion processing unit includes inputting the original image from the imager into the transformation unit, inputting an original image distortion profile into the original distortion profile memory of the transformation unit, and inputting a target distortion profile into the target distortion profile memory of the transformation unit. The target distortion profile is different from the original distortion profile. The method further includes transforming the original image into a transformed image by transforming the distortion profile of the original image from the original image distortion profile to the target image distortion profile, and outputting the transformed image from the transformation unit.
