Abstract: Method and apparatus for removing general geometric lens distortion from images. A geometric distortion removal algorithm is implemented according to a general 5-parameter distortion model that includes both radial and tangential lens distortion components. The algorithm may be implemented in a two-stage process in which one-dimensional elements in one planar dimension (rows or columns) of an input image with geometric distortion are rendered to generate an intermediate buffer, and then one-dimensional elements in the other planar dimension (columns or rows) of the intermediate buffer are rendered to generate an output image with geometric distortion reduced or removed. Thus, one-dimensional sampling is performed, and interpolation is performed in one planar dimension, rather than 2-D interpolation. An input row or column may be decimated, if necessary, before row or column interpolation is performed to generate an output row or column.

Abstract: A method is operable to receive an image, where the image includes an input scene, which in turn includes one or more objects. The method associates a non-regular distribution of pins with the input scene, wherein each pin is associated with a respective portion of the input scene, wherein said associating transforms the image into a first deformation domain.

The method detects structural and/or local similarities between the first and the second domain, and transforms the output scene from the second deformation domain into an output image while preserving both the structural and the local similarities.

Abstract: A display apparatus comprises a display on which first video content of a video signal is presented. In addition, second video content is simultaneously presented e.g. superimposed on the first video content. A presentation processor (209) determines a first characteristic for the presentation of the first video content and a characteristics processor (211) determines a presentation characteristic for the second video content from the first characteristic.

In this case a characteristic of the overlaying is adjusted in response to the presentation characteristic. The invention may provide an advantageous adaptation of secondary (overlay) information to the current characteristics experienced when presenting primary video content.

The calculated volume values are stored in the volume value generator. Under the control of a system controller, the volume values stored in the volume value generator are output to a coefficient generator.
