ABSTRACT:
An image processing apparatus for an endoscope including a smearing component extraction device for extracting a smearing component caused by a high luminance light beam from an original image composed of an image signal of a subject to be imaged. The image processing apparatus also includes a device for correcting the original image composed of the image signal by use of the signal of the smearing component extracted by the smearing component extraction device and reduces or eliminates smearing when a laser treatment is carried out to thereby improve the quality of an image to be observed.
