Description
Claims (5)
- 画像内の解析領域のデータに基づいて前記画像の解析処理を行う画像処理装置において、
画像を構成する各画素のデータに基づいて、前記画像における正反射領域の位置を検出
する領域検出手段と、
矩形領域の位置または大きさを変更する毎に、矩形領域内に前記正反射領域が含まれない場所を検索し、検索により得られた矩形領域に対して評価値を算出し、該算出した評価値に基づいて前記解析領域を設定する領域設定手段と、
を備え、
前記評価値は、前記矩形領域の移動と前記矩形領域の縮小計算毎に更新され、
前記領域設定手段は、予め決められた閾値を超える優良な評価値をもつ矩形領域が得られる毎に前記解析領域の検索範囲を狭めることを特徴とする画像処理装置。 - 前記領域設定手段は、前記算出した評価値と既に行った検索により得られている検索済み評価値との比較に基づいて、前記検索済み評価値を更新し、該更新した検索済み評価値が評価値についての条件を満たす場合、前記検索済み評価値に対応する矩形領域を前記解析領域に設定することを特徴とする請求項1に記載の画像処理装置。
- 前記領域検出手段は、画像全体の画素値の標準偏差と平均値を算出し、該算出した標準偏差と平均値に基づいて第1の正反射領域の画素を抽出し、前記画像を予め決められた大きさの領域に分割して、該領域毎に画素値の標準偏差と平均値を算出し、該算出した標準偏差と平均値に基づいて第2の正反射領域の画素を抽出し、前記第1の正反射領域の画素または前記第2の正反射領域の画素の少なくともいずれかに該当する画素の位置を前記正反射領域の位置として検出することを特徴とする請求項1または請求項2に記載の画像処理装置。
- 画像データに基づいて、画像における測色対象の輪郭を検出する輪郭検出手段を備え、
前記領域設定手段は、前記検索により得られた矩形領域が、前記輪郭検出手段により検出された輪郭の内側にある場合、評価値を算出することを特徴とする請求項1から請求項3のいずれか一項に記載の画像処理装置。 - 前記輪郭検出手段は、前記輪郭検出手段が検出した対象物の輪郭の大きさに応じて、前記矩形領域の初期の大きさを算出することを特徴とする請求項4に記載の画像処理装置。
