Patent ID: 7382399

Claim:
A system for providing perspective corrected views of a selected portion of a received optical image captured using a wide angle lens, the received optical image being distorted, the system comprising: image capture means for receiving signals corresponding to said received optical image and for digitising said signal; input image memory means for receiving said digitised signal; input means for selecting a non-predetermined portion of said received image to view; image transform processor means for processing said digitised signals to produce an output signal corresponding to a perspective corrected image of said selected portion of said received image; output image memory means for receiving said output signal from said image transform processor means; and output means connected to said output image memory means for recording or displaying said perspective corrected image of said selected portion; characterised in that said image transform processor means comprises transform parameter calculation means for calculating transform parameters in response to the selection of said selected portion of said image and processes said digitised signal based on said calculated transform parameters to generate said output signal.
