Claim:
An illuminating system for a camera, comprising: a light source disposed immediately preceding a monolithic illuminating lens, the light source emitting light; and the monolithic illuminating lens arranged in an optical path of the light emitted from the light source and having a fly-eye lens surface with a plurality of lens cells thereon immediately preceding one of an aspherical and spherical lens surface opposite to the fly-eye lens surface, wherein the emitted light is substantially received directly by the fly-eye lens surface from the light source, wherein the illuminating system satisfies the condition: 15 ⁢ ° ≤ tan - 1 ⁢ d D ≤ 31 ⁢ ° where d is a height of each of the lens cells, and D is a distance between the light source and the fly-eye lens surface.
