Abstract: A method for enhancing a wide angle image to improve the perspectives and the visual appeal thereof wide-angle images uses custom adaptive dewarping. The method is based on the scene image content of recognized objects in the image, the position of these objects in the image, the depth of these objects in the scene with respect to other objects and the general context of the image.

Abstract: 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.

Abstract: An optical apparatus captures images of a wide-angle scene with a single camera having a continuous panomorph zoom distortion profile. When combined with a processing unit, the hybrid zoom system creates an output image with constant resolution while allowing continuous adjustment in the magnification and field of view of the image without interpolation like a digital zoom system or without any moving parts like an optical zoom system.

Abstract: 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.

Abstract: Miniature optical lenses are disclosed having a ratio of the optical image diameter divided by the total track length that is greater than 0.85. These thin optical lenses are often used in applications requiring large image sensors and small thickness like in consumer electronic applications. The miniature optical lenses presented have fields of view between 130° and 170° or more specifically inside the well-desired 140° to 160° field of view range in order to cover the ultra-wide-angle field of view range. The optical lenses presented also respect some dimensionless ratios in order to maximize the optical performance of the lenses.

Abstract: A method for designing an optical system creating at least two optical images with different field of view on a common image plane. The optical system includes at least one common optical element receiving the rays of light from the object, at least one splitting element to separate the rays of light in a primary and at least one secondary optical path, at least one reflecting element to orient the rays, at least one element forming an image in the primary path and at least one element forming an image in each secondary path. When an image sensor is located in the common image plane, at least one digital image file can be created from the optical images. Further image processing of the at least one digital image is possible in order to further improve the output from the system.

Abstract: A method for designing a wide-angle optical system having at least one freeform optical surface without rotational symmetry to create a custom 2D object-image mapping. The method is based on iteratively adjusting the at least one freeform optical 2D surface shape to have the exact 2D object-image mapping required and then adjusting the optical element surfaces to meet the other required optical specifications. The iterative method is applied until both the desired 2D object-image mapping and the other required optical specifications are reached.
