To correct a difference in coloring processing on transparent images between manufacturers and obtain an accurate determination result as to contents, etc.SOLUTION: Color correction information for the occurrence ratio of each pixel value in a histogram of hues for other models and a histogram of image information of saturation and luminance per prescribed angle in a hue circle to be precisely matched to the occurrence ratio of each pixel value in a histogram of hues for a main model and a histogram of image information of saturation and luminance per prescribed angle in a hue circle is created. This color correction information for hue, saturation and luminance is converted into color correction information for red, green and blue colors, and the color tone of the image information for other models is converted into the color tone of the image information for the main model by the color correction information for red, green and blue colors. Meanwhile, an object of the image information for other models converted into the color tone of the image information for the main model is determined on the basis of a previously learned learning image for the main model for object determination.SELECTED DRAWING: Figure 7 【課題】透視画像に対する各メーカ間の着色処理の差を補正して内容物等の正確な判定結果を得ることを可能とする。【解決手段】他機種用の色相のヒストグラム及び色相環上の所定の角度毎の彩度及び輝度の画像情報のヒストグラムにおける各画素値の出現率を、主機種用の色相のヒストグラム及び色相環上の所定の角度毎の彩度及び輝度の画像情報のヒストグラムにおける各画素値の出現率に合わせ込むための色補正情報を作成する。また、この色相、彩度及び輝度の色補正情報を赤色、緑色、青色の色補正情報に変換し、他機種用の画像情報の色合いを、赤色、緑色、青色の色補正情報により、主機種用の画像情報の色合いに変換する。そして、主機種用の画像情報の色合いに変換した他機種用の画像情報のオブジェクトを、予め学習されたオブジェクト判定用の主機種用の学習画像に基づいて判定する。【選択図】図７
