PROBLEM TO BE SOLVED: To provide a technique capable of more easily recognizing a numerical value at a counter part.SOLUTION: A character recognition device includes: an image acquisition part 101 for acquiring a picked-up image in which an area including a plurality of characters in parallel is imaged in gradation; a filter processing part 102 for generating a binary image in which the picked-up image is binarized; a character extraction part 104 for extracting a plurality of partial images respectively including a plurality of characters in the picked-up image on the basis of a lengthwise direction projection in which a total brightness is calculated for each ordinate of the binary image and a crosswise direction projection in which a total brightness is calculated for each abscissa of the binary image; and a matching processing part 107 for recognizing characters by matching each of the plurality of partial images with previously stored dictionary data.SELECTED DRAWING: Figure 3 【課題】より容易にカウンタ部の数値を認識することができる技術を提供する。【解決手段】実施形態によれば、並列する複数の文字を含む領域が階調で撮像された撮像画像を取得する画像取得部１０１と、撮像画像を二値化した二値化画像を生成するフィルタ処理部１０２と、二値化画像の縦座標毎に合計輝度値を算出した縦方向射影と、二値化画像の横座標毎に合計輝度値を算出した横方向射影とに基づいて、記撮像画像における複数の文字のそれぞれを含む複数の部分画像を抽出する文字抽出部１０４と、複数の部分画像のそれぞれと予め記憶された辞書データとをマッチングして文字を認識するマッチング処理部１０７を備える。【選択図】図３
