A method and apparatus electronically correct real image distortions caused by lens defects, designed-in distortions (fish-eye lenses), and angular distortion (due to trigonometry, and present in all lenses). The distorted images is directly detected by a photo-sensor array (e.g. a CCD image pickup) as pixel data representing the distorted image; optionally the lens is scanned over a small CCD array to generate different images. The raw image data is downloaded to a computer, in which special software corrects the distortions and reconfigures each raw image onto a virtual spherical surface. The corrected images are juxtaposed to build up a composite virtual image on the virtual sphere. Data representing the virtual image can be transformed back to a flat display surface for viewing any portion of the composite scene without distortion and without discontinuities between juxtaposed images.
