Image pickup apparatus for endoscopes

摘要

An image pickup apparatus for endoscopes, which makes an image of an object to be observed employing a solid-state image pickup device such as a charge-coupled-device, is provided with an optical filter disposed on the optical path including an illumination optical system for applying illumination light to the object to be observed and an objective optical system for forming an optical image of the object to be observed on said solid-state image pickup device, for correcting the spectral properties of said optical path, thereby permitting a faithful color picture image to be reproduced and a picture image suitable for a kind of the object to be observed to be made.
