IMAGE PROCESSING DEVICE, IMAGE READING DEVICE, AND PROGRAM

PROBLEM TO BE SOLVED: To prevent a frequent switchover of processing such as image reading, character recognition and adjustment of an illumination light source while maintaining character recognition accuracy to improve processing efficiency.SOLUTION: An image processing device comprises: a character area extraction unit 281 for extracting character areas from read images under a plurality of illumination conditions; and a character recognition image determination unit 284 for, according to the density of a character included in each of the character areas extracted by the character area extraction unit 281, under the plurality of illumination conditions, determining a read image to be used for character recognition from among the read images under the plurality of illumination conditions.SELECTED DRAWING: Figure 6 【課題】文字の認識精度を維持しつつ、画像の読み取り、文字認識、照明光源の調整という処理の頻繁な切り替えを防ぎ、処理効率を向上させる。【解決手段】複数の照明条件下における読取画像から文字領域を抽出する文字領域抽出部２８１と、前記文字領域抽出部２８１で抽出された前記複数の照明条件下における前記文字領域毎に含まれている文字の濃度に応じて、前記複数の照明条件下における前記読取画像のうち文字認識に用いる読取画像を決定する文字認識画像決定部２８４と、を備える。【選択図】図６
