    摘要: 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)].

    摘要: A method of processing a digital image in order to construct a calculated image, termed the target image (I*), which represents a so-called source image (I) reconstructed with modifications to the tilting angle, panning angle and scale factor in relation to this source image. This method includes determining a common view point (P), for the source image (I) and the target image (I*), as the origin of an orthonormal reference frame; and calculating, for every pixel (M*) with address (X*, Y*) in the target image (I*), spherical coordinates (.alpha., .beta.) by a linear function G.sup.-1 such that (.alpha., .beta.)=G.sup.-1 (X*Y*), the coefficients being functions of the modified tilting and panning angles and scale factor. Finally, the method includes reading a pair (X, Y) which is stored in a table and which constitutes the address of a point (M), in the source image (I), corresponding to the pixel (M*) in the target image (I*), by the matching, to the resolution of the table, the spherical coordinates (.alpha., .beta.) with one of the addresses (.alpha..sub.o, .beta..sub.o) of the table.
