IMAGE PROCESSING APPARATUS, ENDOSCOPE APPARATUS, AND IMAGE PROCESSING METHOD

摘要

This image processing apparatus includes: an image acquisition unit 110 that acquires a plurality of images including a first image and a second image; a filter processing unit 120 that extracts first to N-th frequency band components on the basis of first to N-th band-pass filters; a correlation computing unit 130 that calculates first to N-th correlation computation results at a pixel of interest by computing a correlation between an i-th frequency band component of the first image and the i-th frequency band component of the second image; a reliability level calculation unit 140 that calculates reliability levels of the respective correlation computation results; a weight setting unit 150 that sets weights with respect to the respective correlation computation results on the basis of the reliability levels; and a parallax amount computing unit 160 that calculates a parallax amount on the basis of the weights and the first to N-th correlation computation results.
