Abstract: Methods for correcting an image acquired through an Ultra Wide-Angle (UWA) lens is disclosed, where the entire image is mapped via a transformation that substantially improves the perspective, yet maintains all image information. Additional locally adaptive transformations can be applied to regions of interest in the image to fully restore the perspective. This de-warping scheme allows for flexible manipulation of the image while no content would be lost.

Abstract: Systems and methods for obtaining mapping of Ultra Wide-Angle (UWA) lenses are disclosed. Captured image of a set of grid points on the inner surface of a precision made calibration dome is used as an input image. Image processing techniques are used to identify components of the image and compute the lens mapping. The lens mapping can be used to calibrate the lens against a standard or against other lenses. The mapping can further be used for perspective correction applications.

Abstract: Systems and methods for improving color and brightness uniformity of an image displayed on a backlit LCD are disclosed. In one example, a correction map is computed and applied to the LCD pixel values. In another example, the voltage settings of the backlight source components are also corrected in addition to the LCD pixel values. For efficient hardware implementation, corrections are applied using function representation of a grid data transformation relating measured values to corrected values. In one particular exemplary embodiment, the backlight source is provided by a plurality of LEDs. In another exemplary embodiment, the display consists of a plurality of OLEDs wherein the light source and the display panels coincide.
