IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD AND PROGRAM

To provide an image processing device which enables color evaluation for each portion even when color differences that is allowable for a reference color differ for each part of an inspection object article.SOLUTION: An image processing device 100 is a device that performs color inspection of an article, and includes a reference color setting part 203 that sets a reference color in color inspection, an allowable color difference setting part 201 which sets an allowable color difference in color inspection for each of predetermined image regions of an inspection image object image obtained by photographing the article, a color difference calculation part 204 which calculates a color difference from a reference color in the inspection object image, and a color difference determination part 205 which evaluates a color difference calculated by the color difference calculation part 201 based on the allowable color difference set by the allowable color difference setting part 201.SELECTED DRAWING: Figure 2 【課題】基準となる色に対して許容される色差が検査対象物品の部分毎に異なるような場合でも、各部分の色評価を可能にする画像処理装置を提供する。【解決手段】画像処理装置１００は、物品の色検査を行う装置であって、色検査における基準色を設定する基準色設定部２０３と、物品を撮影した検査画対象像の所定の画像領域毎に色検査における許容色差を設定する許容色差設定部２０１と、検査対象画像における基準色からの色差を算出する色差算出部２０４と、許容色差設定部２０１で設定された許容色差に基づいて、色差算出部２０１で算出された色差を評価する色差判定部２０５と、を備える。【選択図】図２
