Abstract
An apparatus and method is provided for converting digital images for use in an imaging system. The apparatus includes a data memory which stores digital data representing an image having a circular or spherical field of view such as an image captured by a fish-eye lens, a control input for receiving a signal for selecting a portion of the image, and a converter responsive to the control input for converting digital data corresponding to the selected portion into digital data representing a planar image for subsequent display. Various methods include the steps of storing digital data representing an image having a circular or spherical field of view, selecting a portion of the image, and converting the stored digital data corresponding to the selected portion into digital data representing a planar image for subsequent display. In various embodiments, the data converter and data conversion step may use an orthogonal set of transformation algorithms.

32. 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 the received optical image and for digitizing the signal; input image memory means for receiving the digitized signal; input means for selecting a portion of the received image to view; image transform processor means for processing the digitized signals to produce an output signal corresponding to a perspective corrected image of the selected portion of the received image; output image memory means for receiving the output signal from the image transform processor means; and output means connected to the output image memory means for recording or displaying the perspective corrected image of the selected portion; wherein the image transform processor means comprises transform parameter calculation means for calculating transform parameters for the selected portion of the image and processes the digitized signal based on the calculated transform parameters to generate the output signal. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A method for providing perspective corrected views of a selected portion of an optical image captured with a wide angle lens, the received optical image being distorted, the method comprising:
-
providing a digitized signal corresponding to the optical image; selecting a portion of the optical image; transforming the digitized signal to produce an output signal corresponding to a perspective corrected image of the selected portion of the received image; and displaying or recording the perspective corrected image of the selected portion; wherein the step of transforming the digitized signal comprises calculating transform parameters for the selected portion of the image, the calculated transform parameters being used to control the transformation of the digitized signal to generate the output signal. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)
