Summary:To efficiently extract a character with high lightness without performing binarization processing again for an entire image.SOLUTION: An extracting means for extracting a second area which is an area other than the first area recognized by an area analysis processing is provided; a binarization means sets a first threshold value to be set when a binarization process is performed on the second area extracted by the extracting means lower than a second threshold value to be set when the binarization process is performed on the scan data, and a binarization process is performed on the second area based on the first threshold value.SELECTED DRAWING: Figure 7 【課題】 画像全体に対して再度二値化処理を実行することなく、明度の高い文字を効率的に抽出することを目的とする。【解決手段】 領域解析処理によって認識された前記第一の領域以外の領域である第二の領域を抽出する抽出手段と、を有し、二値化手段は、抽出手段により抽出された第二の領域に対して二値化処理を実行する際に設定する第一の閾値を、前記スキャンデータに対して二値化処理を実行する際に設定する第二の閾値よりも低く設定し、第一の閾値に基づき前記第二の領域に対して二値化処理を実行することを特徴とする。【選択図】 図７
