METHOD TO DESIGN MINIATURE LENSES WITH ON-PURPOSE DISTORTION
A method to design miniature wide-angle and ultra-wide-angle lenses by using on-purpose distortion to have shorter focal length than usual for a given image sensor size and a desired image projection. This results in optical systems having miniaturization ratio, defined as the ratio between the total track length and the image footprint diameter, smaller than 0.8. The resulting image from these systems having on-purpose distortion can then be processed with a processor to remove the on-purpose distortion and to output an image with the targeted distortion profile.

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.

This results in optical systems having miniaturization ratio, defined as the ratio between the total track length and the image footprint diameter, smaller than 0.8. The resulting image from these systems having on-purpose distortion can then be processed with a processor to remove the on-purpose distortion and to output an image with the targeted distortion profile.
A miniature wide-angle imaging lens has a miniaturization ratio, of a total track length from the center of a first surface to a focal plane by an image circle diameter, with a value less than 3.0. The imaging lens includes, starting from an object side of the lens, a first group of at least three optical elements, a second group including an aperture stop and an optical element immediately in front of or behind the aperture stop, and a third group of at least two optical elements.

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

A panoramic camera is provided with an orientation sensor to record orientation along with a panoramic image. The display or print image is selected from the captured panoramic image, a warped, non-scale-correct image. The selection of the display image is done using the orientation sensor. The orientation sensor data can be recorded with the panoramic image as metadata. The orientation sensor can also be used to control an external display and/or panoramic image selection during browsing.
