To improve accuracy of character recognition results for a mixed character string in which printed characters and handwritten characters are mixed.SOLUTION: An image processing device includes: acquisition means for acquiring a scanned image obtained by scanning a document including a mixed character string in which printed characters and handwritten characters are mixed; character recognition means for performing character recognition capable of handling both the printed characters and handwritten characters on each character block obtained by performing block selection on the scanned image to acquire each of the character recognition results corresponding to each character block; and extraction means for extracting character recognition results corresponding to the mixed character string in which accuracy of the character recognition results is equal to or more than a threshold from among each of the character recognition results.SELECTED DRAWING: Figure 5 【課題】活字と手書き文字とが混在している混合文字列に対して、文字認識結果の精度を向上させる。【解決手段】画像処理装置は、活字と手書き文字とが混在する混合文字列を含む文書をスキャンして得られたスキャン画像を取得する取得手段と、前記スキャン画像にブロックセレクションを実行することにより得られる各文字ブロックに対して前記活字及び前記手書き文字の双方に対応可能な文字認識を行い、前記各文字ブロックに対応する各文字認識結果を取得する文字認識手段と、前記各文字認識結果の中から、文字認識結果の精度が閾値以上である前記混合文字列に対応する文字認識結果を抽出する抽出手段と、を備える。【選択図】図５
