Image processing system comprising fixed cameras and a system simulating a mobile camera
First Claim
1. An image processing system comprising:
- a system of n fixed real cameras arranged in such a way that their individual fields of view merge so as to form a single wide-angle field of view for recording a panoramic scene,an image construction system simulating a mobile, virtual camera (Cv) continuously scanning the panoramic scene to furnish a target sub-image (Iv) corresponding to an arbitrary section of the wide-angle field of view and constructed from adjacent source images (I1, . . . , Ii, Ij, . . . , In) furnished by the n real cameras,wherein said processing system is a digital system that further comprises;
a luminance equalizing system for overall equalizing of corresponding luminance levels of first and second portions of a digital target image derived from two adjacent source images (Ii, Ij), said luminance equalizing System including first and second luminance correction modules which apply a first and a second correction law (Gi, Gj), respectively, to first and second sets (R,S) of the corresponding luminance levels of the first and the second portion (Ivi, Ivj) of the digital target image derived from said two adjacent digital source images (Ii, Ij), to equalize the corresponding luminance levels to the best possible extent, in accordance with a relation Gi(R)=Gj (S).

Abstract
System for processing digital images includes a system of n fixed real cameras whose individual fields of view merge for recording a panoramic scene. An image construction system simulates a mobile, virtual camera continuously scanning the panoramic scene (Iv) to furnish an arbitrary sub-image, referred to as a digital target image (Iv) constructed from adjacent source images of the real cameras. A luminance equalizing system includes modules which apply correction laws (Gi, Gj), respectively, to the sets (R and F(R)) of the corresponding luminance levels, in portions (Ivi, Ivj) of a digital target image (Iv) constructed from two adjacent digital source images (Ii, Ij) to equalize these corresponding levels in accordance with the relation Gi(R)=Gj[F(R)].
