Patent ID: 7663677

Claim:
An imaging apparatus, comprising: an optical lens unit of a photographic optical system; an imaging device which converts light received through the optical lens unit to electrical signals to output analog image signals; a zooming device which changes a focal length of said photographic optical system; a zooming position detector which detects a current zooming position of the optical lens unit; an A/D converter which converts the analog image signals outputted from said imaging device to digital image signals; a gradation sequence converter which converts a gradation sequence characteristic of said digital image signals by referring to a gradation sequence conversion table for converting the gradation sequence characteristic; a storage device which stores values of a flare characteristic of the optical lens unit, which are preliminarily measured in correspondence with zooming positions of the optical lens unit; and a control device which changes converting amounts of said gradation sequence conversion table based on the current zooming position detected by said zooming position detector and the stored values of the flare characteristic of the optical lens unit so as to remove the influence of the flare, the flare being caused by light other than light from a subject being imaged.
