PROBLEM TO BE SOLVED: To provide a mechanism for comparing an affected area existing in captured images with the same color characteristics, without being subjected to stressful load when a user captures an image and without affecting the change with time of the affected area.SOLUTION: An image processing apparatus includes: setting, as a reference region, a rachel region excluding an affected area existing in a teacher image that serves as a reference image (S1502) obtaining a through-image that is an input image related to the same object as the teacher image (S1503) calculating a color-correcting coefficient for changing the color of the rachel region in the through-image corresponding to the reference image into the color of the reference region and (S1504) correcting the color of the through-image based on the color-correcting coefficient.COPYRIGHT: (C)2014,JPO&INPIT【課題】ユーザーが撮影時に多大な負荷を受けること無く、患部の経時変化に影響されずに同じ色特性で撮影画像に存在する患部を比較できる仕組みを提供する。【解決手段】基準画像である教師画像に存在する患部領域を除く肌色領域を基準領域として設定し、前記教師画像と同一の被写体に係る入力画像であるスルー画像を取得し(S1502)、前記基準領域に対応する前記スルー画像の肌色領域の色を前記基準領域の色に変換する色補正係数を算出し(S1503)、前記スルー画像を前記色補正係数に基づいて色補正を行う(S1504)。【選択図】図15
