Patent ID: 7176968

Claim:
Camera system comprising a camera ( 1 ) provided with an optics system ( 2 ) and a photosensitive image surface ( 3 ) disposed near the optics system symmetrically relative to its optic axis (L), the image of the object (K) refracted by the optics being projected onto the image surface, the photosensitive image surface ( 3 ) being a concave spherical surface whose center of curvature is at the focal point of the optics ( 2 ) and consisting of a matrix of individual photosensitive detecting elements, characterized in that the detecting elements are so arranged on the image surface ( 3 ) that their density is at a maximum on the optic axis (L) and diminishes from the optic axis toward the edge zones, characterized in that the density distribution of the detecting elements on the image surface ( 3 ) is consistent with the function: I ⁡ ( r ) = I 0 ⁢ e - a ⁡ ( x 2 + y 2 + z 2 r 0 ) 2 , where I 0 =density of detecting elements at the origin (on the optic axis), I(r)=local density of detecting elements at radius r from the origin, and a=scaling factor.
