1. A system for correcting wide-angle image data, said system comprising:
- a first input buffer configured to store wide-angle image data;
an image data processor operably coupled to said first input buffer and configured to transform wide angle image data stored in the first input buffer into corrected image data;
an encoder operably coupled to said image data processor and configured to receive and encode the corrected image data in a format suitable for at least one of display and recording of corrected images; and
wherein said corrected image data is not stored in a buffer from the time of transformation by the image data processor until the time said undistorted image data is received by the encoder.

Abstract
An imaging system produces undistorted image data from buffered wide-angle image data without the need for a separate output buffer. Wide-angle image data is transformed, on a pixel-by-pixel basis, as the data for a pixel is required for encoding, to produce output signals in real-time. Predetermined values for functions used in the transformation process are obtained from one or more look-up tables to facilitate transformation.

14. A method for displaying and/or recording corrected image data from wide-angle image data, said method comprising steps of:
-
buffering wide-angle image data;
transforming the buffered wide-angle image data into corrected image data; and
encoding the corrected image data into one or more output signals, without buffering the corrected image data; and
displaying and/or recording the output signals from the encoder. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A system for correcting wide-angle image data, said system comprising:
-
means for storing wide-angle image data;
means for transforming wide angle image data stored in said storage means into corrected image data, said image transformation means being operably coupled to said storage means; and
means for encoding the corrected image data into a format suitable for at least one of display and recording of corrected images without storing the corrected image data in a buffer from the time of transformation by the image transformation means until the time the corrected image data is received by the encoder means, said encoder means being operably coupled to said image transformation means.
